The present invention relates to methods of manufacturing composite fabrics, containing one or more discrete polymeric regions of thermoplastic elastomer composition.

Manufacture of products, characterized by flexibility, i.e. the possibility of at least partially recover the original shape after moderate stretching, may be required for various reasons. For example, the elasticity can be a useful property for fasteners, similar to the garments (for example, diapers, training pants, dresses and so on). The elasticity of clothing can be defined as dynamic adjustment of the service, i.e. the ability to stretch and return to its original state in accordance with the movements of the user.

Elasticity can be useful also in other applications. For example, some fasteners can provide a more stable mount, if they are supported in a taut condition, in which they can be translated by stretching, then under the action of the reducing efforts are held in this state. In other embodiments, the materials elasticity may allow to easily adjust the size (length), fasteners or other items.

Despite the fact that the elasticity allows for is to teach a number of advantages in different applications, her achievement in the manufacture can be associated with a number of problems. Many attempts to ensure the elasticity of the materials was based on the use of discrete elastic components, which, for example, glued or sewn to the lining or other inelastic material component. The problem in the manufacture of such composite products may lie in the difficulty of fixing the elastic components and(or) hold them in place. Additionally, there may be relatively higher cost and greater the volume of works on preparation and attachment of the discrete elastic component of the material. Preparing and attaching discrete elastic components can lead to performance degradation, the emergence of additional waste (if unable to securely attach separate components), etc.

In other examples, the device may be so designed that provides the desired elasticity. For example, many elastic fastening systems based on the use of elastic multilayer linings, in which the elastic material is contained in the form of a film having properties compatible with the lining. This approach may lead to additional increases in the cost of material, because you have to enter compatible elastic layer consisting of several layer is. In addition, many elastic materials are not breathable. If elastic multilayer lining is to be used in garments, it is desirable to perforate the lining to provide the desired permeability. However, such an additional process step increases the cost of manufacturing a flexible multi-layer lining. Another potential disadvantage of elastic multilayer linings is the difficulty of ensuring diversity elastic restoring forces, which you want to create in different parts of the lining.

DETAILED DESCRIPTION of ILLUSTRATIVE embodiments of the INVENTION

The present invention relates to methods and systems for manufacturing kompozitnykh tissues, containing substrate with discrete elastomeric polymeric regions formed on the surface and(or) within the substrate. Below describes the different patterns corresponding to different variants of the composite fabrics that can be produced in accordance with the methods according to the present invention. These illustrative patterns in no way limit the scope of the present invention, which is limited only by the points of the following claims.

For example, certain embodiments of the present invention is described in relation to disposable absorbing moisture products, such as disposable diapers. Nevertheless, it is obvious that the present invention can also be applied to the manufacture of other products, such as hats, dresses, shoes, hygiene items for women, areas of service, requiring connection and so on).

Figure 1 shows a view in section of part of one of the composite fabrics made in accordance with the methods according to the present invention. The composite fabric includes a substrate 10 with a first major surface 18 and a second major surface 19. On the first main surface 18 of the substrate 10 formed many discrete polymeric regions 14. Region 14 may be preferably made of an elastomeric thermoplastic whom is osili, as explained in detail below.

Discrete polymeric region 14 is divided uncovered areas 16 on the first main surface 18 of the substrate 10. As shown in figure 1, the interval, i.e. the size of the unprocessed area 16 between the discrete polymeric regions 14 may be constant or variable. For example, the open area 16 between the leftmost pair of discrete polymeric regions 14 more of an open area 16 between the rightmost pair of discrete polymeric regions 14.

Discrete polymeric region 14 can cover the desired part of the surface of the substrate 10 on which they are formed, although it should be understood that the discrete polymeric region 14 may not cover the entire surface of the substrate 10. Some changes of the percentage of the surface covered by the discrete polymeric regions can be the same as the changes described, for example, in the application for U.S. patent No. 09/257 447 "MATERIAL WITH particular regions of the CONNECTING PARTS," filed February 25, 1999 (published as international application number WO 00/50229).

Despite the fact that the discrete polymeric region 14 is described as being mutually unconnected, it should be understood that some composite fabric made in systems and in accordance with the methods according to the present invention may include a relatively thin skin layer is of a thermoplastic composition, used to generate discrete polymeric regions. This skin layer can in some cases mutually connect some or all of the discrete polymeric region of the composite fabric. For example, where the skin layer is formed of an elastomeric thermoplastic composition, the amount of polymer in the skin layer is, however, sufficient to ensure the elasticity of the substrate outside of the thicker discrete polymeric regions 14.

Discrete polymeric region used in combination with composite fabrics according to the present invention can have various structures. For example, the substrate may be made of woven, nonwoven or knitted material, of paper, film or other continuous material that can be stretched across the gap for processing. The substrate may have a variety of properties, such as extensibility, elasticity, flexibility, compatibility, permeability, porosity, stiffness, etc. in Addition, the substrate may have folds, corrugations or other parts of the deformation of a flat sheet surface.

In some embodiments, the substrate may vary to a high degree of elasticity, in other - elasticity. Tensile fabric, which may be preferred, can be the source of the ultimate tensile strength of at least 50 g with/with whom, preferably 100 g-C/see also tensile fabric can be preferably stretchable non-woven fabrics.

Suitable processes for the manufacture of nonwoven fabrics that can be used when implementing the methods according to the present invention, include, inter alia, the ejection air flow, obtaining a nonwoven spunbond method, the water-jet method, the processes of the material forming the aerodynamic method from the melt and Carden materials. Non-woven materials obtained spunbond method, is produced by extrusion of molten thermoplastic yarn) from a set of output parts (small diameter) comprised by the parts of the mouthpiece of the extruder. The diameter of the extruded filaments decreases rapidly when the tension provided neurectomy, ejector spunbond or other mechanism, as described in U.S. patent No. 4340563 (Appel and others), 3692618 (Dorschner and others), 3338992 and 3341394 (Kinney), 3276944 (Levy), 3502538 (Peterson), 3502763 (Hartman) and 3542615 (Dobo and others). The fabric obtained spunbond method, preferably paste (in some parts or the entire region).

The layer of non-woven fabrics may also be made of bonded carded fabrics. Cardin fabric made from the individual staple fibers passed through the comb - or carding machine, in which there is a separation and combining piece pelnik fibers in the direction of pulling, in the resulting non-woven material with fibers oriented generally in the direction of broaching in the car. For violation of this uniform direction of fiber orientation devices are used for random orientation of fibers.

After the formation of carded fabric paste one or several ways to give the material the desired properties for stretching. One way of bonding powder glue - distribution in tissue with subsequent activation, usually by heating tissue and adhesive with hot air. Another way is decorative bonding, in which a heated calender rolls or equipment ultrasonic welding is used to connect fibers, usually in the form of localized areas of the picture, although if necessary, the fabric can be glued along its entire surface. As a rule, the more fibers glued together, the better stretchability of the fabric.

The ejection air flow is another process by which it is possible to manufacture a fibrous non-woven fabric according to the present invention. In this way the small bundles of fibers, typically having a length of from about 6 to about 19 mm, are separated and fed in vozduhonagrevatel, and then are directed to forming a grid, often there is of negative pressure. Randomly distributed fibers are then glued together, for example, under the action of hot air or spray adhesive.

The fused nonwoven fabric can be formed by extrusion of thermoplastic polymers of the output parts subject to the mouthpiece of the extruder. The flow of molten polymer immediately attenuated high-speed stream of air or steam, is injected along the two surfaces of the mouthpiece of the extruder directly in the place where the polymer goes from the output parts subject to the mouthpiece of the extruder. The final fibers are woven in a concatenated fabric in a turbulent air stream before going on the surface of the collection. As a rule, to ensure sufficient integrity and strength of the fabric according to the present invention the molten fabric should be further bonded to one of the above methods - ejection air flow, sealing or ultrasonic welding.

The tissue can be made stretchable, doing it the slots with a certain interval, as described, for example, in international application number WO 96/10481 (Abuto and others). If you want to get elastic tensile fabric, the frames must be continuous and executed in the fabric before the fabric is connected to any elastic component. Despite the fact that h is of this is attributed to higher difficulties, you can perform the slits in the layer of non-elastic fabric after inelastic fabric layer on the elastic fabric. At least part of the grooves in the inelastic fabric should be almost perpendicular (or have almost perpendicular direction) to the direction of stretching or elastic elongation (at least the first direction) of the layer of elastic fabric. This means that the angle between the longitudinal axis of the selected slot or set of slots and the direction of stretching is 60-120°C. a Sufficient number of required slots is almost perpendicular to the direction of stretching, so that the entire multilayer structure (laminate) is elastic. The formation of the grooves in two directions allows you to take advantage of it if you want the elastic laminate was elastic at least in two different directions.

Non-woven fabric used according to the present invention, may be a tapered or narrowing with the ability to recover non-woven material, described in U.S. patent No. 4965122, 4981747, 5114781, 5116662 and 5226992 (Morman). In these versions of the invention, the nonwoven fabric is extended in the direction perpendicular to the desired direction of stretching. If the nonwoven fabric is left in this extended condition, it will be ways the ability to stretch and recover the original shape in the direction of stretch.

The substrate used according to the present invention may preferably be porous on one or both major surfaces so that when the molten thermoplastic composition is applied on one of main surfaces of the substrate, forming a mechanical connection between the molten thermoplastic composition and the substrate after the molten thermoplastic composition is impregnated and(or) capsulebuy part of the porous surface of the substrate. The term "porous"as used in the description of the present invention relates to structures having voids, as well as structures formed by the set of fibers (e.g., woven, nonwoven, knitted and similar fabrics), allowing the molten thermoplastic composition to seep into the interstices between the fibers. If a porous surface contains fiber, thermoplastic composition may preferably be capsulerebel fiber or a portion of the fibers on the substrate surface.

Used in the present description, the term "fiber" refers to fibers of indefinite length, such as filaments and fibers of a specific length, such as staple fibers. In the methods according to the present invention can be used multicomponent fiber. The term "multicomponent fiber" refers to fibers containing at IU the e two differ from each other equally stretchable in the longitudinal direction of the domains of structured polymers (cross-section) of a fiber, in contrast to mixtures in which such domains dispersed, randomly distributed or not structured. These are distinct from each region can be formed from polymers of different classes (for example, of nylon and polypropylene) or polymers of the same class (for example, of nylon), but differing in properties and characteristics. Thus, the term "multicomponent fiber" refers, inter alia, to concentric and eccentric fiber structures with shell, symmetric and asymmetric fiber structures with in-line arrangement, islet fiber structures, wedge-shaped fiber structures and hollow fibers of these configurations.

The type and structure of the material (material) of the substrate should be considered when selecting an appropriate substrate, on which is applied to the molten thermoplastic composition. Typically, such materials are of such type and structure that they do not melt, soften and do not decompose at the temperature and pressure observed when applying thermoplastic composition to the substrate. For example, the substrate must have sufficient internal strength so that it was not destroyed during the process. Preferably, the substrate should have such strength in the direction of flow in the car when the temperature of the transferring roller, so that it could b the C damage to separate from the platen.

Although the substrate according to the present invention, shown in different cross-sections, defined as a single-layer structure, it should be remembered that they can be both single-layer and multilayer structures. If a multilayer structure, it should be remembered that different layers can have the same or different properties, structures, etc. are Some of the options structures can be described, for example, as submitted in the application for U.S. patent No. 09/257447 MATERIAL WITH particular regions of the CONNECTING PARTS," filed February 25, 1999(published as international application number WO 00/50229).

Discrete polymeric region 14 can be formed on a variety of thermoplastic polymeric materials. Thermoplastic compositions used in the methods according to the present invention must be able to flow into cavities formed in the surface of the transferring roller for transferring the polymer to the substrate, as explained below. In addition, you may want some thermoplastic composition also had a relatively high degree of formemost, i.e. the ability to flow into the cavity and preferably take the form under certain temperature and pressure.

Suitable thermoplastic compositions are compositions capable of being who I am melting. Polymers, which possess a fluidity sufficient for at least partial filling of the recesses, and whose properties do not deteriorate significantly in the melting process. Numerous variety of thermoplastic compositions have the desired melting characteristics and fluidity that can be used to implement the methods according to the present invention, depending on the geometrical characteristics of the recesses and treatment conditions. In addition, it may be preferable that the molten processed materials and processing conditions were selected in such a way that any viscoelasticity properties recovery thermoplastic composition did not lead to a significant separation of the material from the walls of the recesses, while not required to transfer thermoplastic composition to the substrate.

In the description of the present invention, the term "thermoplastic" (and its variants) refers to a polymer or polymer composition which softens under the action of heat and returns to its original state or in a state close to its original state when cooled to room temperature.

Some examples of thermoplastic compositions according to the present invention, among other things, serve as polyurethanes, polyolefins (e.g., polypropylene, polyethylene and the like, polystyrenes, polycarbonates, polyesters, polymethacrylates, copolymers of ethylene and vinyl acetate, copolymers of ethylene and vinyl alcohol, polyvinylchloride, copolymers of ethylene and vinyl acetate, modified acrylate, copolymers of ethylene and acrylic acid, nylone, fluorinated hydrocarbons and the like, These materials can be elastomeric and elastomere (for example, polycarbonates, polymethacrylates and polyvinylchloride).

At least one or more discrete polymeric regions formed on a substrate made of composite fabrics according to the present invention, is made of an elastomeric thermoplastic composition. Elastomeric thermoplastic composition is a polymer composition, which returns to its original state or in a state close to its original state when cooled after melting and exhibits elastomeric properties at ambient temperature (for example, at room temperature and normal pressure). In the description of the present invention "elastomeric" means that the material is practically restores the original shape after stretching. Elastomeric materials may preferably have only a small residual strain, preferably not exceeding 30%, and more preferably not exceeding approximately 20% of the original length at moderate elongation, for example, approximately 50% after deformation and recovery. Elastomeric materials can be as pure elastomers, and mixtures thereof with elastomeric phase, exhibiting sufficient elastomeric properties at room temperature. In U.S. patent No. 5501679 (Krueger and others) discussed discrete elastomeric materials that can be used when implementing the methods according to the present invention.

Elastomeric thermoplastic composition can contain one or more polymers. For example, an elastomeric thermoplastic composition may be a mixture of polymers with such elastomeric phase, which composition exhibits elastomeric properties at room temperature. Suitable elastic thermoplastic polymers include block copolymers, as block copolymers a-b or a-b-C (for example, block copolymers of styrene-isoprene-styrene, styrene-butadiene-styrene, styrene-ethylene-butylene-styrene), elastomeric polyurethanes, olefinic elastomers, in particular elastomeric copolymers of ethylene (for example, ethylene-vinyl acetates, the elastomer on the substrate copolymers, ethylene/octene, the elastomer on the substrate ternary copolymer of ethylene-propylene-diolefin), and also mixtures of the aforementioned substances and mixtures of these substances with other elastomeric or elastomere thermoplastic polymers.

Ter is plasticine composition, used according to the present invention may also be combined with various additives introduced to achieve the desired effect. Such additives include, for example, fillers, substances to reduce the viscosity, plasticizers, increase stickiness, dyes (for example, paints and pigments, antioxidants, antistatic agents, improves binding properties of the additive, caking substances that improve slip additives, stabilizers (for example, a stabilizing state upon exposure to heat and ultraviolet rays), foaming agents, beads, glass beads, reinforcing fibers (e.g., microfiber), facilitating connector mold substances, thermally conductive particles, electrically conductive particles and other experts in the field of processing and use of such materials will be able to determine the amount of the above substances, which can be useful in thermoplastic compositions.

Figure 2 and 3 shows another variant of the composite fabric produced by the method according to the present invention. This fabric includes a substrate 110, on which formed are many discrete polymeric regions a and 114b. The width of the substrate 110 formed of folds 102 (width is defined between the opposite edges 111 of the substrate 110).

Discrete sex is dimensional region a is an example of discrete polymeric region, extending along the length of the substrate 110 so that the discrete polymeric region a covers many folds 102, as shown in figure 2 and 3. Discrete polymeric region 114b are examples of reduced discrete polymeric regions covering only one fold 102 formed in the substrate 110.

If discrete polymeric region a and(or) 114b made of an elastomeric thermoplastic composition, they can prevent smoothing the folds 102 or restore folds to their original condition when the substrate 110 is stretched so that the folds 102 smoothed.

Discrete polymeric region 114b of smaller size have an oval shape, however, it should be understood that these areas may have different shapes, for example the shape of squares, rectangles, hexagons, etc. Area can not only be right or irregular geometric shape, but also to form arbitrarily with the perimeters of irregular shape. In addition, the area may not necessarily be continuous spatial figures, but may contain internal cavities which do not enter thermoplastic composition. In yet another embodiment, some or all of the discrete polymeric region can be in the form of characters, such as letters, numbers, or graphics.

Figure 4 show the n perspective view of one system and illustrated the method of forming discrete polymeric regions on one surface of the substrate 210 according to the present invention. The system, shown in figure 4, includes a substrate 210, which defines the path pulling the material through the system. The substrate 210 is moved through the system in a downward direction shown by the arrow of rotation of the various rollers. After uncoiling or supply a different way from the source (for example, the substrate 210 can be made using the system shown in figure 4), the substrate 210 is directed into the gap to transfer between the support roller 220 and carrying the platen 230.

The process of forming discrete polymeric regions on the substrate 210 provides for the filing of the molten thermoplastic composition on the exterior surface 232 transferring roller 230, the outer surface 232 which is made from one or more recesses 234. The molten thermoplastic composition 241 is supplied to the outer surface 232 transferring roller 230 transfer device in the form of troughs 240 (or other device such as an extruder, gear pump and the like). Excess molten thermoplastic composition is removed from the outer surface 232 of the rod 242 in contact with the outer surface 232 transferring roller 230. Despite the fact that the ideal is the removal of the entire thermoplastic composition from the exterior surface 232 transferring roller 230, a portion of thermoplastic composition may remain on the outer surface is STI 232 after the removal compositions of the rod 242.

In the recess 234 formed in the outer surface 232 transferring roller 230, preferably take the part of the molten thermoplastic composition, when the molten thermoplastic composition is applied to the outer surface 232 transferring roller 230. If the recess 234 is not completely filled during the deposition of the molten thermoplastic composition, removing thermoplastic compositions of the rod 242 with the outer surface 232 transferring roller 230 can facilitate proper filling of the recesses of the molten thermoplastic composition.

Although figure 4 illustrates the application of only one thermoplastic composition using the carrying roller 230, it should be understood that the outer surface of the carrying roller 230 can be applied at least two different thermoplastic compositions. On figa shows part of one system, in which the groove 340 is used to feed the three of molten thermoplastic compositions (in zones a, b and C) on the surface of the transferring roller 330, rotating around the axis 331. Trench 340 may, for example, contain partitions 342, so that the molten thermoplastic composition in the different zones of the trench 340 will not be commingled with the application process. In another embodiment, a separate and different troughs can be used for different thermoplas the ranks of the compositions, supplied to the transferring roller 330. Gutters or zone used, for example, to simultaneously feed carrying roller 330 elastomeric and not elastomeric thermoplastic compositions.

Carrying roller 330 also contains different sets of recesses a, 334b and s, through which might be different molten thermoplastic composition. Deepening in different zones on the carrying roller 330 different shape, have different sizes and are placed with different time intervals. For example, a triangular depressions in the area placed in irregular, non-repetitive order, and deepening in zones a and b in a regular, repetitive manner.

Using the system shown in figa, different sets of discrete polymeric regions can be formed on a single substrate using different thermoplastic compositions. In thermoplastic compositions can be selected for any set of different properties associated with the production or end use of the finished products made from composite fabrics.

Temperature control various rollers in the system, shown in figure 4, can be useful for obtaining the desired products. For example, it may be preferable that the outer surface 232 transferring roller 230 is heated to a selected temperature less than the melting temperature of thermopla is part of the composition, transferred to the substrate 210. The heat transferring roller 230 may also contribute to the filling of the recesses 234 molten thermoplastic composition.

Since the molten thermoplastic composition 241 itself generates heat in the groove 240, the rod 242 is usually heated molten thermoplastic composition. In another embodiment, it may be necessary to adjust the temperature of the rod 242 separately from the temperature of the trench 240, in which the molten thermoplastic composition 241. For example, you may need to heat the rod 242 to a temperature above the melting temperature of thermoplastic composition.

On FIGU shows a partially enlarged view in section, which illustrates the relationship between the rod 242 and a recess 234 in carrying platen 230. Another feature of the squeegee 242, which can be adjusted is the thickness or length 243 along the outer surface of the carrying roller 230 (measured in the direction of flow in the car or in the direction of rotation of the transferring roller). For example, Raquel 242 increased thickness or length will allow the molten thermoplastic composition to stay longer in the recesses 234, thus improves the filling of the recesses. In addition to changing the length of the rod 242 is also possible to regulate the pressure or force acting on the carrying roller 230 withfrom device 242, in accordance with various factors, including, for example, characteristics of the molten thermoplastic composition, the characteristics of the transferring roller, etc.

When the recess 234 is at least partially filled with the desired molten thermoplastic composition, carrying the platen 230 continues to rotate as long as the recesses 234 and the molten thermoplastic composition contained in the cavities will not be brought into contact with the substrate 210 by using the supporting roller 220 in the gap between the transferring rollers (for example, in the gap formed between the transferring roller 230 and the supporting roller 220). At this point begins the transfer of the molten thermoplastic composition from the recesses 234 on the substrate 210. It should be remembered that, under certain conditions, only a portion of thermoplastic composition can be transferred from the recesses 234 on the substrate 210.

If the implementation of the methods according to the present invention uses the substrate 210 containing at least one porous main surface, on which is applied to the molten thermoplastic composition, the mechanical connection is formed preferably by infiltration of the molten thermoplastic composition in the porous surface of the substrate 210. The term "porous"as used in the description of the present invention, tositsa structures, with emptiness, as well as structures formed by the set of fibers (e.g., woven, nonwoven, knitted and similar materials), allowing the molten thermoplastic composition to seep into the interstices between the fibers.

The pressure in the gap between the transferring roller 230 and the supporting roller 220 preferably should be sufficient to ensure that the portion of thermoplastic composition in discrete polymeric regions has infiltrated portion of the porous substrate 210 or capsulerebel part of the substrate 210 to improve the fastening of the discrete polymeric regions on the substrate 210. If the surface of the substrate 210 contains fiber (for example, if the main surfaces of the substrate 210 has a woven, nonwoven or knitted material), it may be preferable that thermoplastic composition has capsulerebel all or part of at least some of the fibers on the surface of the substrate 210 to improve the fastening of the discrete polymeric regions on the substrate 210.

Under certain conditions, the molten thermoplastic composition contained in the recesses 234, may completely pass through the substrate 210, for example, if the substrate 210 porous throughout the thickness. In other conditions, the infiltration of the molten thermoplastic composition may be limited to the outer layer or layers of the substrate 210.

However, the footprint of the em understand although the outer surfaces of the substrate 210 may vary some porosity, the pores do not necessarily extend through the entire thickness of the substrate 210. For example, the substrate 210 may include various layers, one of which contains almost no time. In another embodiment, the entire thickness of the substrate 210 pores may be absent, although in General the outer surface of the substrate 210 may vary some porosity.

The supporting roller 220 may have different characteristics depending on the types of substrate materials and(or) the molten thermoplastic compositions. In some versions the outer layer bearing roller 220 may be made of rubber or other tight-fitting material that takes the form of a carrying roller 230. If you use a tight-fitting material, such as rubber, it can be determined by the Durometer hardness 10-90 units shore, A.

One of the options in the migration process in the gap illustrated in figs, which shows that the adjacent support roller 330 enters the portion of the substrate in the recess 334 (which contains a thermoplastic composition 341). If the surface of the substrate 310 facing the recess 341, contains pores, the portion of the molten thermoplastic composition 341 may be entered or to impregnate the porous surface of the substrate 310. Enter the substrate 310 deepened in the e may be especially useful if the recess 334 is not completely filled with the molten thermoplastic composition 341. When such operation increases the likelihood of a reliable contact between the substrate 310 and the molten thermoplastic composition 341.

In another embodiment, the substrate can be entered into the cavities on the surface of the transferring roller by means of the supporting roller. The area of the gap between the rollers for this option is shown in fig.4D. The support roller 320' includes protrusions 322', matching or coordinated with grooves 334' on the surface of the transferring roller 330'. In a preferred embodiment, the protrusions 322' direct substrate in the recess, which allows to obtain the same results and advantages described above for the variant shown in figs. The support roller 320' may be made of any compatible material, incompatible material or combinations thereof.

The process of heating or temperature control carrying roller has been described above. Note that you can also adjust the temperature of the outer surface of the bearing roller. For example, you may want to cool the surface of the support roller to a selected temperature below the temperature of the transferring roller. Cooling bearing roller may be useful to maintain the integrity of the substrate, especially if the integrity of the substrate may be the arosen the heat-carrying platen when the platen is heated or molten thermoplastic composition in the recesses on the surface of the transferring roller.

After passing through the gap formed between the supporting roller 220 and the transferring roller 230 and the substrate 210 around the supporting roller 220, as shown in figure 4. In some embodiments, the portion of the molten thermoplastic composition in the recesses, can remain in the recesses 234 as long as the substrate 210 is supplied from a transferring roller 230. In the molten thermoplastic composition in the recesses 234 may be in the form of threads to run between the recesses in the surface of the transferring roller 230 and the substrate 210.

To separate these strands of thermoplastic compositions which can be formed as branches of the substrate 210 from the carrying roller 230 may be used such a device as a heated wire 244, shown in figure 4. To separate the filaments of molten thermoplastic composition can also be used with other devices and / or methods. Examples, among others, can serve as a hot air knives, lasers, etc. in Addition, under certain conditions, the filament thermoplastic composition may not be formed in the process.

The possibility of formation of filaments of molten thermoplastic composition contained in the recesses 234, at the exit of the substrate from a gap between the rollers also poses another problem is s, which should be taken into account in the development of technological processes according to the present invention. This problem is related to the internal cohesive strength and / or tensile strength of the substrate 210. This problem can be especially acute if the substrate 210 has a fibrous structure (for example, made of a fibrous woven, nonwoven or knitted material), which can be separated from the rest of the substrate, applying force when the substrate 210 is supplied with a carry roller 230. These problems can be particularly important if the molten thermoplastic composition has properties (e.g., adhesion, tensile strength and so on)that the threads of this composition can affect the substrate 210 with a force greater than the internal cohesive strength and / or tensile strength of the substrate 210.

For example, if the substrate 210 includes a non-woven part with a polymeric binder, the temperature of the transferring roller 230 and(or) the molten thermoplastic composition can rise above the melting temperature of the rubber, which can lead to the decrease of internal cohesive strength and / or tensile strength of the substrate 210. In another embodiment, the nonwoven substrate can contain fibers having a melting temperature comparable to the temperature of the transferring roller 30 and / or the molten thermoplastic composition, therefore can decrease the internal cohesive strength and / or tensile strength of the substrate 210.

In any case, you may need to adjust the temperature of the platen and(or) the molten thermoplastic composition to ensure the integrity of the substrate during the transfer to it of the molten thermoplastic composition. For example, the support roller 220 can be cooled, resulting in the substrate 210 also cool and will be supported by the required internal cohesive strength.

In another embodiment, it is possible to heat-carrying platen 230 and(or) the supporting roller 220 to increase the internal cohesive strength and / or tensile strength of the substrate 210. For example, if the substrate 210 includes a multicomponent fiber or fiber containing a different composition, when heated substrate 210 during the transfer to it of the molten thermoplastic composition from carrying roller 230 may be a slight sticking of fibers with other components of the substrate 210, which can improve the integrity of the substrate due to the formation of the skin layer or other reinforcing structures on the surface or inside of the substrate 210. Some examples of such processes are described in U.S. patent No. 5470424 (Isaak and others).

Having described some basic characteristics of composite tissues, as well as methods and systems for manufacturing according to us is oasea the invention, describe specific applications of the present invention.

Figure 5 as an example of the finished product shown disposable diapers 470 containing at least one component made in accordance with the present invention. Diapers 470 contain the basis 472, which may be made of various materials used for the manufacture of such products. Discrete examples of structures diapers are described in particular in U.S. patent No. 5399219 (Roessler and others) and 5685873 (Bruemmer and others).

Diaper 470 includes a mounting tabs 474, protruding laterally from the base 472 and attached to opposite side edges of at least one waist portion 473 for fastening sections of the waist part of the product on the body of the child during use of the product. In a preferred embodiment, the mounting tabs 474 made of composite fabrics according to the present invention.

Diaper 470 also includes the area of 476 for receiving fastening straps placed in the waist part of 475 at the opposite end of the diaper 470. The mounting tabs 474 may be connected to portions 476 to secure the diaper on the body of the child. Although figure 5 shows only two of the bracket with the tabs, it should be understood that in some versions can only be used one such area b is lesego size, passing in the transverse direction in the area of the waist portion 475.

Region 476 fastening of the fastening straps may be of any suitable structure for holding the mounting tabs 474. For example, if the fastening tab contains 474 formed on her hooks region 476 may be performed, for example, in the form of loops, for which engage the hooks to hold the mounting tabs 474 in the field 476.

Figure 6-8 shows various views of one of the mounting reeds 474 attached to the diaper 470, to illustrate various features of the present invention. The mounting tab 474 includes a substrate 410, which is formed of different discrete polymeric region. These discrete polymeric region represent a mechanical fastening (a) for attaching straps 474 additional surface (for example, the receiving surface 476 shown in figure 5) and elastic elements (414b) to impart elasticity of the fastening tongue 474. Tongue 474 preferably has an axis of tension 478 shown in Fig.6.

Discrete polymeric region a placed near the far end of the webbing 474. 7 shows a view in section along the line 7-7 shown in Fig.6, and patterns 412 protruding from the base 413 discrete polymeric region a. In the variant shown in Fig.7, patterns 412 are mounting structure in which noreste hidden areas of short rods with heads, although may be used instead a variety of other mounting structure.

Patterns 412 are oriented almost perpendicular to the base 413 discrete polymeric region a and the substrate 410, although it should be understood that the exact form and structure of the rods 412 may vary depending on the destination of the composite fabric. In addition, although all the terminals 412 is shown as having the same size and shape, it should be understood that depending on the purpose of fixing tongue 474 can be used rods 412 of different sizes and / or shapes.

Discrete polymeric region a can be made of elastomeric or elastomeric materials, although preferred, may be discrete polymeric region a made from elastomeric materials, if you want the discrete polymeric region a also distributed load over the width of the fixing tongue 474 (width measured generally in the direction transverse to the axis of stretching 478 shown in Fig.6). You may want to distribute the load applied during stretching straps 474, to prevent narrowing or kinking straps 474. The load distribution can also be useful to improve the uniformity of applying loads in the direction across the width of the webbing 474.

The mounting tab 474 also includes discrete on kernie region 414b, which preferably function as elastic elements, which gives the elasticity of the strap 474, if you are using inelastic substrate 410. If you are using elastic substrate 410, the discrete polymeric region 414b can still be used as elements for improving the elasticity of the strap 474. In order region 414b could perform the function of elastic elements, they are made of an elastomeric thermoplastic composition as defined above.

Despite the fact that the substrate 410 in the preferred embodiment, is extensible, inextensible substrate 410 can do tensile, for example, through the slot 406. In a preferred embodiment, the slot 406 is performed with the interval defined by at least one discrete elastomeric polymeric region 414b. Some examples of execution of the slots described in the international patent # WO 96/10481 (Abuto and others). To ensure or improve the elasticity of the substrates used in the implementation of the methods according to the present invention can also be used in other ways. For example, the processes of mechanical strain described in U.S. patent No. 4223059 (Schwarz) and 5167897 (Weber and others).

In the described embodiment, the discrete polymeric region 414b placed on the same surface of the substrate 410, and the discrete polymeric region a. In the preferred embodiment, to which each of the discrete polymeric regions 414b length placed along the axis of stretching 478. For the purposes of the present invention the length of the discrete polymeric regions 414b equal to the size of the longest straight line regions 414b, measured along the surface of the substrate 410.

Another feature of the discrete polymeric regions 414b is uneven or varying width. As shown in Fig.6, the discrete polymeric region 414b become wider as the distance from the discrete polymeric region a. If the height or thickness of the discrete polymeric regions 414b above the surface of the substrate 410 is constant, the effect of changing the width, illustrated at 6, is that the amount of elastomeric material in discrete polymeric regions 414b increases as the distance from the discrete polymeric region a. Changes in the volume of elastomeric material, for example, you can receive the fastening tongue 474 with different elasticity and / or relative lengthening at different sites along the axis of stretching 478. Other variants of the distribution of mass of elastomeric material in discrete polymeric regions 414b can be used to provide the required elasticity and(or) relative elongation of the fixing tongue 474, for example, you can adjust the thickness of the polymeric regions, materials, etc.

Figure 9 shows one system that can be used for manufacturing, for example, mounting straps 474 shown in Fig.6-8, in which all discrete polymeric region placed on the same surface of the substrate 410. The system is provided to transfer a substrate 410 in the direction of the arrows on the left and right sides of the media path, and rotation arrows on different cylinders.

The substrate 410 is initially directed in a first gap formed between the support roller 420 and the first carrying roller a. In the outer surface a first carrying roller a formed deepening a. The device a supply of the molten thermoplastic composition, mounted on a carrying roller a, is used to fill the recesses 43 4A desired molten thermoplastic composition.

After passing through the first gap of the transfer material on the substrate 410 are formed of discrete polymeric region a. Since in the preferred embodiment, the discrete polymeric regions a formed on the fixing tongue 474, there is some structure formed to provide a mechanism of the mounting substrate 410 with discrete polymeric regions a can be directed into the gap formed between a tool for molding 450 and the support roller 422. In the described system, this gap for molding is a process line for transferring the gap to carry the CA.

Despite the fact that the gap for molding shown as formed between a tool for molding 450 and the support roller 422, it should be understood that in another embodiment, the clearances for transferring and molding can be formed using the same bearing roller. Use the same bearing roller to form gaps for transferring and molding allows to obtain such an advantage, as, for example, reducing the number of components and(or) the area occupied by the equipment in the system.

In those systems and the ways in which the gaps for transferring and molding are formed using different supporting rollers, a thermoplastic composition in discrete polymeric regions a can be sufficiently melted to form structures in the gap for molding. In this case, the discrete polymeric region a on the substrate 410 may need to be heated before passing through the gap for forming (heating can be performed, for example, both contact and non-contact heat source).

Tool for forming 450 having the form of a roller, contains a cavity 452 formed in the surface. Specialists in the art of well-known tools for molding shown in Fig.9. Separate tools for molding is described, for example, in U.S. patent No. 4984339 (Provost and the R.), 5077870 (Melbye and others), 5755015 (Akeno and others), 5868987 (Kampfer), 6132660 (Kampfer), 6190594 B1 (Gorman and others), 6287665 B1 (Hammer).

Tool for forming 450 and(or) support roller 422 can be heated or cooled to the selected temperature depending on the properties of thermoplastic compositions formed to improve the formation of discrete polymeric regions with cavities 452 in the tool 450. For example, it may be desirable to heat or cool the tool for forming 450 to improve the molding process. Depending on the speed of execution of the process and other factors discrete region of thermoplastic composition, placed on the substrate 410 may also mainly to preserve some properties of melt migration on the substrate 410.

In any case, the part of thermoplastic composition in discrete polymeric regions a placed on the substrate 410, introduced in the cavity 452 on the instrument for molding 450. As a result, such structures as the connecting rods of the parts shown in figure 9 (see also Fig.6 and 7), can be formed in discrete polymeric regions a placed on the substrate 410.

In some embodiments the invention, thermoplastic composition is applied in discrete areas on the substrate 410 may have such properties (such as viscosity and the like), thermoplastic composition which I repeats the shape of the cavities 452 tool for molding 450. The term "repeats the form" (and its variants) refers to both full and partial repetition of form cavities 452 thermoplastic composition. In other embodiments, the properties (such as viscosity and the like) thermoplastic composition can lead to the transfer of the composition to the substrate 410 in such a form that, despite the difference of this form from the form thermoplastic composition before forming tool 450, the shape of the cavities 452 is not repeated, as it was necessary in accordance with the above conditions.

After transfer of thermoplastic composition and the formation of discrete polymeric regions a substrate 410 is sent to the second carrying gap, in which the substrate 410 are formed of discrete polymeric region 414b. The second transfer gap is formed between the second transferring roller 430b and the support roller 420b, and also the device 440b supply of the molten thermoplastic composition mounted on the carrying roller 430b to fill the recesses 434b formed in the outer surface 432b-carrying roller 430b, the desired molten thermoplastic composition.

The substrate 410 extending from the second carrying gap contains a second set of discrete polymeric regions 414b formed in addition to the discrete polymeric regions a with two sets, positioning the situations on the same surface of the substrate 410. Different sets of discrete polymeric regions a and 414b may be made of the same thermoplastic compositions.

Because the substrate 410, coming in the second carrying gap, contains a set of discrete polymeric regions a may require, for example, use anchor rollers with the design used for the systems shown in figv and 4C, to provide additional efforts to facilitate the transfer process of the material.

Figure 10 shows a composite tissue 500, which may be at least partially made using the system shown in Fig.9. Composite fabric contains 500 different discrete polymeric region a and 514b. Furthermore, the composite fabric contains 500 lines branch 517 defining the boundaries of different fastening tongues similar to the tongues described above with reference to Fig.6-8. Line departments 517 define the integrated configuration of the fixing reeds, including discrete polymeric region a and 514b, so that can reduce the amount of waste, when the composite fabric 500 is separated along the lines 517 to obtain the required mounting reeds. Line departments 517 can have any suitable shape that facilitates the separation of the composite fabric 500 along the lines of separation, for example, this can be the scribing line, the line of weakness, perforin the private lines, etc

In a preferred embodiment, the longitudinal axis of the composite fabric 500 runs along the direction of the straight line branch 517 passing from left to right, as shown in figure 10. Despite the fact that the composite fabric 500 width contains only two pairs of built-in mounting straps (width measured in the direction perpendicular to the longitudinal axis of the material), it should be understood that a single composite fabric according to the present invention can be used any desired number of nested pairs.

On 11-13 show various views of another fastening tongue 674, which can be used for different items of clothing and, in particular, for a diaper. The fastening tongue 674 includes a multilayer substrate 610, which includes a variety of discrete polymeric region. These various discrete polymeric region provide mechanical fastening (using discrete polymeric regions a) to attach the tongue 674 additional surface and elastic elements (region 614b) to impart elasticity of the fastening tongue 674. In a preferred embodiment, the tongue 674 has an axis stretching 678, shown at 11.

Mechanical fasteners in the form of discrete polymeric regions a placed near the far end of the fixing tongue 674. On Fig shows a view in section along line 12-12, while the Anne of figure 11, and structure 612 (e.g., hooks)protruding from the discrete polymeric regions a. In the embodiment of the invention shown in Fig, structure 612 are in the form of hooks, though, instead of such hooks can be used a variety of other suitable structure. Discrete polymeric region a used to provide mechanical bonding with the tongue 674, can be made of elastomeric or elastomeric materials.

The fastening tongue 674 also contains discrete polymeric region 614b, which preferably function as elastic elements, which gives the elasticity of the reed 674, if you are using inelastic substrate 610. If you are using elastic substrate 610, the discrete polymeric region 614b can still be used as elastic elements, which gives the elasticity of the reed 674. In order discrete polymeric region 614b could perform the function of elastic elements, they are made of an elastomeric thermoplastic composition as defined above.

In the described embodiment of the invention the discrete polymeric region 614b placed between the substrates Suite 610a and 610b of the multilayer substrate 610. Such a structure may be necessary for the protection of discrete elastomeric polymeric regions 614b and enhance the softness of the fastening tongue 674. One and the variants of the method and system of manufacturing multilayer composite fabric is described below with reference to Fig.

In the preferred embodiment, each of the areas 614b in length placed along the axis of stretching 678. For the purposes of the present invention the length of the discrete polymeric regions 614b equal to the size of the longest straight line regions 614b, measured along the surface of the substrate 610.

Unlike polymeric regions with variable widths, shown in Fig.6, the polymer region 614b are almost constant width over its entire length. Variables elasticity and(or) relative elongation can, however, get, forming a more discrete polymeric regions of different lengths, so that their total volume or mass became larger as the distance from the discrete polymeric regions a along the axis of stretching 678. If the height or thickness of the discrete polymeric regions 614b, the measured thickness of the substrate 610, are constant, the effect of changing the width, illustrated at 11, is that the amount of elastomeric material in discrete polymeric regions 614b increases as the distance from the discrete polymeric region a. Changes in the volume of elastomeric material, for example, you can receive the fastening tongue 674 with different elasticity and / or relative lengthening at different sites along the axis of stretching 678. Many other variants of distribution of the mass of elastomeric material in thesis the specific polymer areas 614b may be used to provide the required elasticity and(or) relative elongation of the fixing tongue 674, for example, you can adjust the thickness of the polymeric regions, materials, etc.

On 11 and 13 illustrates another additional feature in the form of a binding site 628 formed on the substrate 610. Section 628 may be used to facilitate attachment of the mounting tongue 674 to a larger object, such as a diaper, dress, etc. To facilitate attachment of the binding site 628 may have a different configuration. For example, the binding site 628 may be a fortified area of the woven or non-woven material suitable for thermal or other methods of hardening. In another embodiment, or in addition to a hardening materials the binding site 628 may contain one or more materials to promote adhesion, such as block copolymers, ethylene vinyl acetates, ethylene-vinyl acetates, high adhesiveness, adhesives (contact, curing, thermoactivation etc.), amorphous polyolefins, and the like, the Specific choice of materials for the formation of a section 628 depends on the type of communication and binders.

One of the advantages, which allows to obtain the binding site 628, is that it can be made from materials that are suitable for almost used method of attachment, such as heat-sealing, ultrasonic welding, etc. the Other is the second advantage is that what is the size of the binding site can be defined so that it was large enough to perform the desired function, but not too large that I had to remove waste any materials used in the formation of the site. Depending on the composition of the materials used in the forming section 628, this area can be formed by means of transfer materials described in this invention, when forming section 628 you want to use thermoplastic composition.

In some disposable products, such as training pants, the binding sites can be generated to associate the item with a similar item. The plot of clutch formed on one or both elements. On figa shows the product contains two binding site a and 628b, placed on opposite sides of the field containing discrete elastomeric polymeric region 614 on the substrate 610. If the product shown in figa should be used as, for example, the fastening tab may be preferred that one or both of the binding site a and 628b were adapted for receiving mechanical fasteners that can be attached to the strap separately. In another embodiment, an adhesive (e.g., contact, curing, thermoactivation etc)or binder may be placed inside one or two sections of the clutch a and 628b.

On FIGU shown another product containing discrete polymeric regions on the substrate according to the present invention. The product formed on the substrate 610', contains two discrete polymeric region 614', which may contain, for example, hooks, rods with the heads and other mounting structure. At least one, and preferably several discrete elastomeric polymeric regions 615' placed between two discrete polymeric regions 614' on the product.

On Fig shows one of the systems, which can be fabricated, for example, fastening straps 674, as shown at 11 to 13, in which the discrete polymeric region is placed on the outer surface of the substrate 610, and the other region between the substrates, forming a multi-layer substrate 610. In the system provides the transfer fabric in the direction of the arrows on the left and right sides of the media path, and rotation arrows on different cylinders.

The substrate a is initially directed into the first gap for transfer formed between the support roller a and the first carrying roller a. In the outer surface of the first carrying roller a formed recess. The device a supply of the molten thermoplastic composition, mounted on a carrying roller a, is used to fill the recesses of the required races is lawrenoe thermoplastic composition. After passing through the first gap to transfer material to the substrate a formed discrete polymeric region a.

The system also includes the supply of the second substrate 710b, which is sent to the second gap formed between the support roller 720b and the second transferring roller 730b. In the outer surface of the second transferring roller 730b formed recess. The unit 740b supply of the molten thermoplastic composition, mounted on a carrying roller 730b, is used to fill the recesses of the desired molten thermoplastic composition. After passing through the second gap of the transfer material on the substrate 710b are formed of discrete polymeric region 714b.

Since in the preferred embodiment, the discrete polymeric regions 714b, there is formed a structure to ensure the retention mechanism, the substrate 710b, including discrete polymeric region 714b, can be directed into the gap formed between the tool for forming 750a and the support roller 720b. In the path of feed of the substrate 710b this gap for molding is for clearance for the transfer of the composition.

Tool for forming 750a, having the form of a roller, contains a cavity formed in the surface. Specialists in the art of well-known tools for molding, as shown figure 11. OTDELENIE tools for molding described, for example, in U.S. patent No. 4984339 (Provost and others), 5077870 (Melbye and others), 5755015 (Akeno and others), 5868987 (Kampfer), 6132660 (Kampfer), 6190594 B1 (Gorman and others), 6287665 B1 (Hammer).

Tool for forming 750a and(or) support roller 720b can be heated or cooled to the selected temperature depending on the properties of thermoplastic compositions formed to improve the formation of discrete polymeric regions with cavities in the tool 750a. For example, you may need to heat or cool the tool for forming 750a to improve the building process. Depending on the speed of execution of the process and other factors separate area of thermoplastic composition, placed on the substrate 710b may also mainly to preserve some properties of the melt during the transfer to the substrate 710b.

In any case, the part of thermoplastic composition in discrete polymeric regions 714b placed on the substrate 710b, is introduced into the cavity of the tool for forming 750a. As a result, such structures as the rods, as shown figure 11, can be formed in discrete polymeric regions 714b placed on the substrate 710b.

After transfer of thermoplastic composition and the formation of discrete polymeric regions 714b substrate a and 710b are directed into the gap for lamination, formed between the rollers 750b and 722, where the substrate superimposed on each other is so the discrete polymeric region a placed between the substrates a and 710b, a discrete polymeric region 714b - on the surface of the laminated substrate 710.

In the gap lamination formed between the rollers 722 and 750b, the portion of thermoplastic composition in discrete polymeric regions a can soak into the substrate 710b and(or) to capsulerebel at least part of at least some of the fibers, if any, in the substrate 710b. If this mechanism is used for laminating substrates, no additional materials or processes for lamination is not required.

When performing lamination in the absence of any substances or technical equipment may be required to polymer region a remained in the molten state, which will allow for linking with the response of the discrete polymeric regions on the opposite substrate or the opposite substrate. In another embodiment, the lamination of the substrates a and 710b can be performed using a variety of materials and(or) different ways, known to experts in the art, for example by heat sealing, by means of adhesives, resins, binders, films and fabrics, etc. See for example, U.S. patent No. 2787244 (Hickin), 3694867 (Stumpf), 4906492 (Groshens), 5685758 (Paul and others) and 6093665 (Sayovitz, and others).

The layered structure of the description of the data with links to 11-14, can be useful, for example, to make both surfaces of the composite fabric more natural look or softness, ensuring air permeability, porosity, etc. These features make the multi-layer composite materials from fabrics in which all discrete polymeric region is available on the open surface of the composite fabric. Such multi-layer structure of the composite fabric, as shown at 11 and 12, can also be used to impart different properties opposite sides of the composite fabric. Different substrate a and 710b may have different porosity and other properties.

Clearance for lamination formed between the rollers 750b and 722 may also function as a station of deformation structures formed on discrete polymeric regions 714b, if such operation is required. Station deformation can be performed, for example, different processes of deformation structures in discrete polymeric regions 714b after their formation in the gap for molding. Examples of suitable processes running in the field station, strain, serve, among other things, straightening, removal of a layer of abrasive processing with heat or fusion (using contact or non-contact heat source), bending or other deformation structures. If you use t is the cue structures such as rods, the deformation may include, for example, forming heads on the rods, forming a hook on the rod, bending fittings, etc. Some of the devices and processes described, for example, in U.S. patents 5077870 (Melbye and others), 5868987 (Kampfer and others), 6039911 (Miller and others), 6054091 (Miller and others) and 6132660 (Kampfer).

After leaving the gap laminated substrate 710 may be directed to additional workspace, formed rollers 780 and 724. This workspace can also perform the function of deformation in addition to the gap for laminating or instead of the gap. Another potential process that can be performed in the area between the rollers 780 and 724 are formed in the laminated substrate 710 lines of separation, similar to the lines of separation 517 described above with reference to figure 10.

On Fig shows in plan is shown as one example of the deepening 834 in carrying platen 830 according to the present invention, and Fig - deepening 834 in section along line 16-16 shown in Fig. Deepening 834 has a round tip shape (i.e. round hole shape deepening 834 on the surface of the roller 832), the diameter of which is designated as d. Deepening 834 has a depth (indicated by the letter h), measured from the outer surface 832 carrying roller 830.

In a preferred embodiment, carrying VA is IKI, used when implementing the methods according to the present invention may contain cavities that are large enough for the formation of discrete polymeric regions with dimensions sufficient to support, for example, the formation of multiple short of fasteners or other structures in each of the discrete polymeric regions. Deepening can be described in different ways. For example, deepening 834 can be described in terms of the area occupied by the recess on the outer surface of the tool for forming the maximum size (in any direction on the surface of the roller), the volume of the recess, the shape of the recesses, etc.

If the cavities are described from the point of view of the area occupied by the recesses, each recess 834 occupies an area of not less than approximately 4 mm2. In other embodiments, each of the recesses 834 may have an area of not less than approximately 8 mm

Another way of describing recesses, the maximum size occupied by the recess when measured at the surface 832 carrying roller 830. To deepen the circular form shown in Fig and 16, most will be resized in any direction, however, the recesses formed according to the present invention can have any desired shape (e.g., elongated, irregular, etc.), in which the maximum size is determined is only in one or more directions on the outer surface of the carrying roller 830. If for descriptions of the recesses, use the largest size occupied by the recess, the recess can have the greatest size of not less than approximately 2 mm, in certain embodiments not less than approximately 5 mm

Recesses formed according to the present invention may also be characterized by the volume. For example, the indentations may have a volume of at least approximately 3 mm3in another embodiment, at least 5 mm3. The volume of the discrete polymeric regions may be important to ensure thermoplastic composition in a quantity sufficient for the proper filling of the cavities in the tool for molding. The volume of the recesses may play an important role as well because at least part of thermoplastic composition can stay in the pits during migration of the material, i.e. in a preferred embodiment, the volume of the cavities can be determined with a margin relative to the preferred volume of the discrete polymeric regions to compensate for the amount of thermoplastic composition, lingering in the recesses.

On Fig shows two recesses 934 formed in the outer surface 932 carrying roller, and Fig - view of one of the recesses 934 in section along line 18-18 shown in Fig. Deepening 934 have an elongated shape, e.g. is made in the form of a gutter. Compared with round recesses 834 shown in Fig and 16, a longer recess 934 shown in Fig and 18, are larger in the longitudinal direction than in the cross.

The orientation of the recesses 934 may be selected based on many factors. Deepening 934 elongated shape can be oriented in the feed direction of the substrate in the car, in the transverse direction of the material (i.e. in the direction transverse to the feed direction of the substrate) or in any other direction between the direction of flow in the machine and transverse direction of the fabric.

On Fig and 20 shows another embodiment of the methods of manufacturing composite fabrics according to the present invention. On Fig shows a view in plan of part of the composite fabric made in accordance with the present invention. The composite fabric includes a substrate 1010, which includes two discrete polymeric region 1014 and 1015. The substrate has two opposite edge 1011 extending along the length of the composite fabric. These edges together define the length of the composite fabric in the longitudinal direction.

Discrete polymeric region 1014 is formed as a line of thermoplastic composite material, deposited on a substrate 1010 by the length of the composite fabric in the longitudinal direction. Discrete polymeric region 1014 may be continuous is Noah in the longitudinal direction of the composite fabric, as shown in Fig.

Discrete polymeric region 1015 is a variant of the discrete polymeric region 1014. Region 1015 has a wavy shape in contrast to the relatively straightforward form of discrete polymeric region 1014. However, the wavy shape of the discrete polymeric region 1015 is stretched along the longitudinal direction of the composite fabric. In addition, the discrete polymeric region 1015 may be continuous in the longitudinal direction of the composite fabric, as shown in Fig.

On Fig shows a perspective view of one carrying roller 1030, which can be used to transfer thermoplastic compositions in the form shown in Fig, in accordance with the methods according to the present invention. On the surface of the transferring roller 1030 formed recess 1034, in the preferred embodiment, extending continuously along the outer circumference of the roller 1030 for the formation of discrete polymeric region 1015 shown in Fig. In carrying the shaft 1030 is provided by the deepening 1035, which also passes through the outer circumference of the roller 1030, thus forming the discrete polymeric region 1015, as shown in Fig.

On Fig shows another embodiment of the methods of manufacturing composite fabrics according to the present invention. On Fig shows a view in plan of part of the composite is the second fabric, manufactured in accordance with the present invention. The composite fabric includes a substrate 1110, which formed discrete polymeric region a, 1114b and is located across the width of the substrate. The substrate 1110 has two edges 1111 extending along the length of the composite fabric. These two edges that define the width and the length in the longitudinal direction of the composite fabric.

Each of the discrete polymeric regions a, 114b and is formed in a line from thermoplastic composition applied to the substrate in the transverse direction, i.e. between the opposite edges 1111 substrate 1110. Discrete polymeric region a, 1114b and s have different shapes. Region a and 1114b have the form of straight lines, and the area s - wave shape. For methods according to the present invention can be defined a variety of accommodation options, shape and / or orientation of the discrete polymeric regions.

In addition to applying thermoplastic polymer in discrete areas, it is assumed that the main surface of the substrate can be by known methods applied additional materials. These materials can be, for example, adhesives, described in particular in U.S. patent No. 5019071 (Bany and others), 5028646 (Miller and others) and 5300057 (Miller and others), or binding materials, described in particular in U.S. patent No. 5389438 (Miller and others) and 6261278 (Chen et al).
