THE TECHNICAL FIELD

The present invention relates to the infinite structures and, in particular, to the technical fabrics, which are used in the production of non-woven products. More specifically, the present invention relates to supporting elements such as tape or sleeves, which are used in the production of having the figure, marked or textured non-woven products.

THE LEVEL OF TECHNOLOGY

For many years known methods of production of non-woven products. According to one method of fiber layer or canvas is processed by the flow of water or water jets for plexus fibres with each other and enhance the physical properties, such as strength of the canvas. For decades, the known ways of processing of the fibers jets of water, as can be seen from the description of U.S. patent # 3214819, №3508308 and # 3485706.

In General this method involves the interlocking of single fibers with each other through the action of high pressure water jets, which act on the fibre structure as needles and provide the opportunity to direct a part of fibers for the formation of a cloth in the thickness direction.

Currently, this method is widely developed and used not only in the production of what are known as "hitrospleteniya" or "Hydrobotany", for use in the textile industry, in particular for applications in the field of medicine and hospitals, treatment, filtration and packaging of tea bags, and perforation of the small openings in continuous media, such as paper, cardboard, film, even plastic sheets, etc. and the resulting products can be regular and homogeneous, as follows from the description of U.S. patent number 3508308, and optionally may contain patterns that result repurpose fiber, which is important for aesthetic purposes, as can be seen from the description of U.S. patent number 3485706.

In connection with the products of the type "hitrospleteniya" or "Hydrobotany" it has long been known that the final properties of the product can be selected through the formation of mixtures of material, for example, by combining fabrics, containing fibers of different types, for example, natural, artificial or synthetic, or even canvases in which fiber pre-mixed (blade type "spanbond" and so on) with reinforcing elements that can be built into the woven structure.

In patents France FR-A-2730246 and 2734285 corresponding to the U.S. patent # 5718022 and # 5768756 described solutions successfully process hydrophobic fibers or their blends with other hydrophilic fibers or even paintings, composed entirely of natural fibers, by means of water jets.

In General terms, in accordance with the ideas of these documents processing involves processing of fabric bases, generated from a single fibers of the same type or of different types, compression and hydration specified canvas basics and then weave the fibers with at least one rack allied jets of water under high pressure acting on a fabric basis.

To this end, the canvas basics moves forward on a moving infinite porous support and transferred to the surface of a perforated rotating cylindrical drum to the internal part of which is attached a partial vacuum. Canvas basics of mechanical compressed between the porous support and a rotating drum that both are moving forward essentially the same rate. Directly downstream from the zone of compression water curtain goes to the canvas and continuously passes through the porous support, compressed fabric basis and supports the perforated drum, which sucks the excess water.

Single fiber continuously infused still on a rotating cylindrical drum, when concise and moistened cloth is exposed at least one rack jets of water under high pressure. In General binding is implemented by successive racks jets of water that act or on the same side, or alternatively on both sides of the fabric, the pressure inside the poles and speed jets from one stand to another usually decreases.

It is important to note, as FR 2734285 that perforated shaft can contain holes, distributed randomly. If necessary, after the initial linking processing of fiber non-woven fabric may be subjected to a second treatment is applied to the reverse side.

In the process of production of nonwoven hitrospletenij and hitrospletenij products it is desirable to create a picture or marking on the final product, in order thus to give the product the desired appearance (design). Usually, such a picture or marking create using the helper process that uses the shaft calender, separately from the formation of non-woven sheet, and of the process of wrap. Typically, these shafts are expensive and operate on the principle of compression certain sections of fiber cloth to create the desired picture or markings. However, there are several disadvantages of using separate processes for creating a drawing or marking on non-woven product. First, for the acquisition of calender rolls require large initial investment of money, which may limit the amount of work that can be economically justified by the manufacturer. Second, due to the additional stage of drawing or markings appear higher production costs. Third, the final product will have more material than it takes to save the item thickness after shrinking at the stage calendering. Finally, a two-stage process will lead to a small volume of final products due to strong compression in the calendering process. Known from the prior art nonwoven products made by such known process of drawing, do not have clear, precise elevated part and, consequently, the required drawings trudnorastvorimy. In addition, the size of the elevated parts known from the prior art embossed non-woven products unstable, and raised the elements loose their three-dimensional structure, when they are under stress, such as when using or washing.

In the U.S. patent # 5098764 and # 5244711 disclosed application supporting element in the later method of obtaining of non-woven cloths or products. Supporting elements contain the configuration with the characteristic surface topography, as well as an array of holes. In this process the source of fiber cloth is placed on supporting element with relief surface. Supporting element with on him fiber cloth is held under the jets of liquid, usually water, under pressure. A jet of water cause the fibers to twist and weaved with each other in a special design, based on the configuration of the surface relief support element.

Figure formed by the surface topography and the holes in supporting element is crucial for the structure of the obtained non-woven products. In addition, supporting element must have sufficient structural integrity and strength to maintain fiber cloth, while streams of liquid reorienting and twist fiber in the new order with the formation of stable tissue. Supporting element should not be exposed to any significant curvature under the action of liquid streams. In addition, supporting element must have a means for removal of relatively large amounts of fluid used to hitrospleteniya fibers to avoid "flooding" fiber cloth that would prevent the effective tangling. Usually supporting element contains the drain holes which should be sufficiently small to ensure the integrity of fiber cloth and prevent the loss of fibers through which form the surface. In addition, supporting element on the merits should not contain burrs, hooks and similar irregularities that may hinder withdrawal of tangled non-woven products. At the same time supporting element should be such that the processed on him fiber optic paintings will not be washed away by the action of liquid jets.

One of the main tasks that occurs when obtaining of non-woven products, is to reach the clutch patterns to make products of the mechanical characteristics of the application, along with preserving and making special physical characteristics, such as volumetric weight, tactile sensations, appearance, etc.

Properties such as volume, absorbing ability, strength, softness and aesthetic appearance is really important for many non-woven products, when used as intended. For obtaining of non-woven products with these characteristics, it is often necessary to create such supporting fabric, tape, or the sleeve in which contact with the surface of the sheet has a surface relief.

It should be noted that the fabric can be in the form of an infinite loop, or can be made of the infinite and work like a conveyor belt or worn in the front of the sleeve. In addition, it should be noted that obtaining of non-woven products is a continuous process, which is carried out at a considerable speed. That is, the individual fibres or layers of fibers continuously put on forming material forming part of, while it is just made of non-woven cloth continuously wound on rolls after drying.

SHORT DESCRIPTION OF THE INVENTION

Provided other benefits, such as, but not limited to, more efficient wet molding, improved removing the paintings in comparison with known from the prior art woven materials, due to the lack of rocker threads present in woven materials to capture a single fibers, and improved ease of cleaning.

Hence, the main purpose of the invention consists in hitrospletenij" or "gidrostanok" support item, such as cloth, tape or sleeve that contains contact with the canvas surface pattern of the sequence raised pads and corresponding grooves, which gives texture made it non-woven product.

Another aspect of the description of the invention consists in that structure contains cavities, such as through-hole for passing water or air, or both.

In one embodiment, the implementation revealed the structure of the fabric that is used to create textured non-woven products, permeable to air and water, containing contact with the sheet surface with the image consisting of a sequence raised pads and corresponding grooves giving the texture made it non-woven product, and the sequence through voids, ensuring the passage of water and air from the surface of the fabric inside surface.

One variant of implementation relates to supporting element such as tape or sleeve, for keeping and transportation of polymer fibers in the process of hitrospleteniya or Hydrobotany. Many non-woven products are calendering after forming in the helper process. During this process, one shaft calender (or both) may contain on the surface of the picture that used to give texture nonwoven product. Tape or sleeves according to the present invention show the following non-limiting advantages in comparison with the specified separate process calendering, sleeves are relatively less expensive elements and do not require large financial investments in stationary equipment, drawing directly in the molding process, thanks to which eliminated the need for separate additional process; you can achieve lower material consumption of final products, as the thickness of the products is not reduced after compression in the calendering process; can be made of the final products a large volume weight, as it is uncompressed at any stage. For the manufacturer of nonwoven roll goods, in addition, the advantages of the process leads to the following advantages of the final product: lower cost hitrospletenij and hitrospletenij paintings with pictures or marking; possibility of manufacturing products according to customer requirements, because it greatly reduces the alignment of the size of the figure is higher production performance, since more volumetric weight leads to more absorbency, which is of great importance in the application of the consumer.

Tape or sleeve according to the present invention are endless structure with permeability usually in the range of 100 to 500 cubic feet per minute (2,83-14,15 m 3 /min) and may contain any number of layers, such as one, two or three layers. Polymeric materials such a structure can consist of extrudable thermoplastic materials or resins in which cross-connections are formed or at room temperature, or when UV radiation, or heat, for example, in collections of polyester, acrylic or polyurethane copolymers. Materials are chosen so that to guarantee the use of process hitrospleteniya at pressure water stream up to 250 bar.

One variant of implementation refers to the tapes or sleeves to get hitrospletenij and hitrospletenij non-woven products. Tape, or supporting element, or sleeve is permeable to water or air support element, which can be extruded or laminated films in which these holes to obtain the necessary permeability to water and/or air. These holes can have various diameters in the range from 0.01 mm to 5 mm and different input angles on the surface of the tape or sleeves. The shape of the holes can be round, square, oval or any other, such as a star. The holes on the surface of the supporting element can be placed randomly or specific density in some areas or are evenly on the surface, depending on the desired effect. Instead of a hole can be cut/corroded lines or grooves on the support element or the ribbon to create drawings or even logos. Supporting element can be manufactured with one or more layer of polymer film, with or without amplification, and it can be woven or non-woven. In addition, it can be made in the form of laminate with woven or non-woven layer located between two or more layers of the polymer film. This increased improves mechanical characteristics and stability tape/sleeves.

The supporting surface of the item can be processed to create a relief surface cutting or engraving of a picture, for example, cellular structure, and/or can be processed chemical coating for specific applications, such as the dissipation of static charge, Department of dirt/mud, increase lifetime and so on the Surface of the supporting element can be engraved, for example, to create a relief surface for printing. Supporting element can be done as a sleeve for installation on a drum (sleeve), or as an infinite or stitched tape, or as a supporting element. Use of support element of this type provides a better reflection of hydraulic energy in comparison with known from the prior art standard belt. Supporting element of this type improves traction in non-woven material and prevents the penetration of fibers in a hole/hole/void-aware tape, which can lead to loss of fibres or cause difficulties when removing non-woven material evenly with a supporting tape/sleeves, as can be seen in woven strips or supporting elements. The result is a better grip fibers and less plucking fibers, as a consequence, improves the removal of the cloth or a transfer with the specified supporting element to another, supporting element or to another position. Contact with the machine components party may have a set of strings of single fibers oriented in the machine direction (MN), laminated or partially embedded in a supporting tape/ sleeve to create a higher degree of drainage.

A DETAILED DESCRIPTION OF THE PREFERRED OPTIONS FOR THE REALIZATION

Here is a detailed description of the invention with reference to the accompanying drawings which depict the preferred options for the implementation of the invention. However, the present invention can be implemented in many forms and should not be construed as limited presented in this description of variants of realization. On the contrary, the data presented in this description of options for implementation are listed in order to present the description was very complete and fully transferred to the specialists volume the invention.

For example, the present invention provides continuous support element for use in the device shown in figure 1 and 2. Specified non-woven supporting element performs the functions of a traditional woven supporting material and contributes towards made it non-woven products required textures, tactile sensations and volume. Supporting element according to the present invention can reduce production time and costs associated with the production of nonwoven materials.

Tape or sleeve, as specified in this description contains two sides: in contact with the canvas or list and contact details of the machine or the opposite direction. The first side to support the so called because it speaks to the newly formed non-woven cloth. The last side of the so called because it passes on the side and touches the ramparts or cylinder machines for production of non-woven products.

Figure 1 shows the device for continuous production of non-woven products with the use of the support item in accordance with the present invention. Depicted in figure 1 the device contains belt 80, which actually serves as a supporting element with a relief surface in accordance with the present invention. As is known from the prior art, the tape moves counterclockwise, for example, around a pair of shafts, placed at a distance from each other. Above conveyor belts 80 is throwing liquid distribution pipeline, 79, joining the ranks or group 81 nozzles. Each group contains one or more of a number of nozzles or holes of a very small diameter, approximately 0.007 " (0,018 cm), on 30 such nozzles per inch (2.54 cm). Water is supplied to groups 81 nozzles under a pre-set pressure and ejected from the nozzle in the form of very thin, essentially a columned, not divergent streams or water jets. The distribution pipeline is equipped with gauges 88 and regulating valves 87 to adjust the pressure of the fluid in each row or group of nozzles. Below each number or group nozzles located Luggage suction 182 removal of excess water and prevent excessive flooding of the site. Fiber cloth 83, which will be formed in the fabric according to the present invention, served on supporting element with a relief surface or conveyor belt. Water sprayed through the appropriate tip 184 on fiber cloth for preliminary humidifying incoming sheet 83 and for the control of fibers as they are under-emitting liquid distribution pipelines. Suction crack 85 located below the specified tip to remove excess water. Fiber cloth is held under throwing water distribution pipeline counterclockwise. Working pressure in any group 81 nozzles can be installed independently from the operating pressure, installed in the other group 81 nozzles. Typically, however, the working pressure in the group 81 nozzles located closer to the tip 184, is relatively low, for example 100 pounds per square inch (psi) (0,69 MPa), which helps when you install incoming sheet on the surface of the support element. Because the web is in a counterclockwise direction, as shown in figure 1, the working pressure in each group 81 nozzles normally increases. Not necessarily that each group 81 nozzles works at a higher pressure than the neighboring group in a clockwise direction. For example, two or more neighbouring groups 81 nozzles can work under the same pressure, after which the next group of 81 nozzles (counterclockwise) will work under a different pressure. Usually working pressure at the end of a conveyor belt, where the cloth is removed, higher than where the canvas originally supplied to the conveyor belt. Although figure 1 shows six groups 81 nozzles, this number is not mandatory, but will depend on the volume weight fabrics, speed used pressure, quantity of rows of holes in each group, etc. After the passage between throwing liquid separation pipeline and suction separator piping, a newly formed non-woven fabric passes over additional intake slit 186 to remove excess water. Usually the distance from the bottom surfaces groups 81 nozzles up to the top surface of the fiber cloth 83 varies from about 0.5 to 2 inches (1,27-5.08 cm), preferably from about 0.75 to 1 inch (1,91-2.54 cm). Obviously, the canvas can't be located as close to the distribution pipeline that they touch. On the other hand, if the distance between the bottom surface of nozzles and the top surface of the canvas is too large, liquid jet will lose energy and the process will be less effective.

Figure 2 shows schematically the other device to obtain the nonwoven materials with the use of the support item in accordance with the present invention. This device supports an element with a relief surface is sleeve 191 rotating drum. For example, the drum 90 under the sleeve 191 rotates counterclockwise. The outside surface of the sleeve 191 drum contains the desired supports the configuration of the terrain. Near the part of the external surface of the drum is the distribution pipeline 89 connecting strip 92 nozzles for water or other liquids on the fibre cloth 193, located on the outer surface curved plates. Each band of the nozzles may contain one or more rows of holes of a very small diameter above in this type description. Usually the hole diameter is approximately 0.005-0.010 " (0,013-0,026 cm). May be there are 50 or 60 holes per inch or more, if required. Water or other liquid is directed through a series of nozzles. Basically, and as explained above, the pressure in each group nozzles normally increases from the first group, which runs fiber cloth, to the last group. Pressure regulating the appropriate regulatory valves 97 and tracked with the help of manometer 98. Drum connected to septic tank, 94, which can be attached to a vacuum in order to facilitate the removal of water and prevent flooding of the site. During the operation of fiber cloth 193 feature on the top surface of the supporting element with a relief surface before throwing water distribution pipeline 89, as seen in figure 2. The fiber blade goes below bands nozzles and is formed in the non-woven material according to the present invention. Then formed the road passes over the section 95 of the device, in which there are no bands nozzles, but continues to use the vacuum. Material after dehydration is removed from the drum and pass through a sequence drying drums 196 for drying.

Now let us turn to the structure supporting elements such as described above tape or sleeve, supporting elements can have relief in the form of pass-through cavities. Through emptiness can have, inter alia, geometrical characteristics, providing superior surface relief sheet and the volumetric weight of non-woven products or sheets/canvases, for example, made on supporting element 80, 191. Another advantage of these supporting elements is more than simply removing the paintings from the support element.

In addition, the supporting elements made according to the present invention, in the form of a deeper "fingerprints"that leads to the creation of non-woven products with large volumetric absorption capacity and smaller density. It should be noted that the term "through the emptiness" is synonymous with the term "through hole" means any hole that completely goes through supporting element, such as a tape, or a sleeve. Supporting element, which is presented in this description includes, but is not limited to, technical fabrics, such as conveyor belts and hoses or cylindrical tape, especially used in production of nonwoven materials.

Another advantage is that the design of a supporting tape/sleeves avoids the limitations and necessary in a traditional loom, because through emptiness, grooves or other images can be located anywhere on the picture, and, therefore, can be improved aesthetic appearance sheet/leaf. Surface-aware tape/sleeves can be processed to create pictures by cutting or engraving of a picture, for example, cellular structure, and/or can be processed chemical coating for specific applications, such as the dissipation of static charge, Department of dirt/mud, longer service life, etc. Use of support element according to the present invention provides a better reflection of energy in comparison with the known standard woven ribbon, which improves the tangling fiber non-woven products and prevents fibers in the gap/hole/void-aware tape, which can lead to loss of fibres or cause difficulties when removing non-woven material evenly with a supporting tape/sleeves, as can be observed when using woven tapes or supporting elements. The result is a better grip fibers and less plucking fibers, as a consequence, improves the removal of the canvas or moved with the specified supporting element to another, or to another position.

For example, on figa and 4B illustrates one way to get support item, such as a tape or sleeve, according to one variant of realization of the present invention. For example, on figa and 3B illustrates top view-through cavities 102 formed as part of the continuous support of the item 104, according to the manner illustrated in figa and 4B. Through the emptiness in some application areas can serve as drainage holes for passage of fluid, water and/or air. On figa shown many cross-cutting void 102 in the perspective of upper or of contacting with the plate surface 106 supporting element 104. Each of the cross-cutting voids 102 may have a conical shape, in which the inner surface of each of the 108 void 102 narrowed from inside the hole 110 on the upper surface 106 through the hole 112 (FIGU) on the bottom or in contact with components of the machine surface 114 (FIGU) supporting element 104. Bore diameter 110 on the X-axis is indicated as Δx 1 , and bore diameter 110 on the Y-axis is indicated as Δ 1 . According FIGU likewise bore diameter 112 on the X-axis is indicated as Δ 2 , and bore diameter 112 on the Y-axis is indicated as Δ 2 . As seen on figa and 3B, diameter Δ 1 hole 110 X on the upper side 106 supporting element 104 greater than the diameter Δ 2 holes 112 X on the bottom 114 supporting element 104. In addition, the diameter Δy 1 hole 110 on the Y-axis on the upper side 106 supporting element 104 greater than the diameter Δ 2 holes 112 on the Y-axis on the bottom 114 supporting element 104. In other variant can be used opposite geometry. For example, the diameter of the holes on the contact sheet side may be greater than the diameter of the holes on the side in contact with the components of the machine.

On figa shows a cross-section of one of the cross-cutting void 102 depicted on figa and 3B. As previously described, each of pass-through cavities 102 may have a conical shape, in which the inner surface of each of the 108 void 102 narrowed from inside the hole 110 on the upper surface 106 through the hole 112 on the lower surface of 114 supporting element 104. The conical shape of each of the end-to-end voids 102 can be formed as a result of the incident optical radiation 202, generated optical source, such as CO2 laser or other device. Using laser radiation 202 with the relevant characteristics (for example, output power, focal distance, pulse duration, and so on), for example, to non-woven supporting element can be formed through the emptiness 102 as a result of perforating surfaces 106, 114 supporting element 104 laser radiation. In addition, to create the above-through cavities or holes can be used for mechanical perforation or penetration.

As shown in figa, according to one aspect of laser radiation 202 creates when exposed first raised edge or ledge 204 on the upper surface 106 and second raised edge or ledge 206 on the lower surface of 114 supporting element 104. In addition, the data raised edges 204, 206, can be called as the flared or edge. Top view from the top point on the raised edge 204 marked A. Similarly, bottom view from the lower point on the raised edge 206 marked A. The height of each raised edges 204, 206 can vary from 5 to 10 microns. The height is calculated as the difference of levels between the surface of the support element and the top of the raised edge. For example, the height of the raised edge 204 is measured as the difference of levels between the surface 106 and the upper part 208 raised edges 204. Raised edges, such as 204 and 206, provide, among other benefits, local mechanical reinforcement for each cross-cutting void or each through hole. In addition, deeper void create deeper "fingerprints" in the resulting non-woven material, as well as lead, for example, to the big volume weight and lower density. It should be noted that the attitude Δx 1 /Δx 2 can be equal to 1.1 or greater, while the ratio of Δ 1 /Δ 2 can be equal to 1.1 or greater in all cases. Alternatively, it may be used opposite geometry. For example, the diameter cavities or holes in contacting with the plate surface may be greater than the diameter cavities or holes on the surface that is in contact with components of the machine. Alternatively, in some or all cases, the attitude Δ 1 /Δ 2 can be set to 1 and the ratio Δ 1 /Δ 2 can be set to 1 with the formation of the so-through cavities of the cylindrical form. In addition, the "ledge" can be formed on one or both surfaces.

Laser head 310 brings falling optical radiation 312 on supporting element 302 from the outlet of 314 for the formation of through voids 304. Falling optical radiation 312 may be exposed to a variety of components that form the optical beam various forms, before exiting outlet 314. For example, can be used in different location optical lenses to achieve the required working distance (i.e. D w ) between the outlet 314 laser head 310 and the top surface of the support item 302. In addition, optical couplers, isolators, polarizers, cracks and/or other components can be used to change various properties associated with the incident optical radiation 312 coming out of the laser head 310. For example, the regulation of the size and shape of the spot may be one desired properties. In fact, the incident optical radiation prosverlivayut (or cuts) through hole or through emptiness in supporting the item 302. In addition, the same device can be used for engraving or etching drawings from attachment, continuous or intermittent, straight, wavy, or sinusoidal inside surface. In addition, can also be erased logos.

Supporting element 302 can be mounted or placed on a suitable device 320 (for example, on this, what is depicted in figure 5), with different mechanical components, guides, videos, etc. to facilitate the movement to support the 302 and/or laser head 310 in a certain direction X and Y coordinates. By controlling the movement to support the 302 in the direction of the X and Y coordinates, it can be created in the surface topography of the through holes, grooves, pictures, logos, etc required according to different pictures. In addition to move in the direction of the X and Y coordinates distance D w can be changed by setting the laser head 310 on artificial platform that provides moving in the direction of the coordinate Z. You can develop a system whereby the laser head moves in three directions, while supporting element remains stationary. Alternative, the laser head can move across a supporting element in cross-machine direction ("MO") axis "X" (cross-machine direction), while supporting the item is moved in the machine direction ("MN") or on the axis "Y". In addition, you can install a system in which supporting element moves in three directions relative to mechanically fixed laser head.

Figure 5 shows cited as an example of the embodiment of the device 320 used to generate cross-cutting gaps in the ribbon or the sleeve according to one aspect of the invention. It should be understood that supporting element 322, depicted in figure 5, is a relatively short part of a complete tape supporting element 322. Where supporting element 322 is infinite, will be the most practical to install it around a couple of rolls, not shown in the drawing, but well known to specialists. In this situation the device 320 will be located on one of the two sides, the most comfortable on the upper side, supporting element 322 between the two shafts. However, regardless of whether it is supporting element 322 infinite or not, preferably where it is located, with a corresponding tension. Moreover, to prevent sagging supporting element 322 while moving through the device 320 can be supported from below the horizontal support element.

Now refer to figure 5, which supports the item 322 shown moving upstairs through the device 320, as implemented method according to the present invention, a device 320 contains a sequence of several positions, through which supports the item 322 can be carried out with a certain step, while from it produce a tape or a sleeve.

The above variant of implementation of the tape or sleeves is one example of a supporting element to be manufactured according presented in this description of systems and methods. Required characteristics through these cavities formed in the ribbon or the sleeve, improve one or more characteristics associated with the production of non-woven products manufactured by car to hitrospleteniya or Hydrobotany.

Figure 6 shows the contact sheet side and side-contact details machines that support elements made according to one aspect of the present invention. The image 602 illustrates through emptiness in supporting element, as they are visible from the upper part or the part that is in contact with the sheet, supporting element. The image 604 illustrates through emptiness in supporting element, as they are visible from the bottom party support element (i.e. from contact with parts of the machine). Criteria through the voids are designed to achieve round-through cavities containing the top open area on the side in contact with the sheet. As seen in the image 604 602 and, on contact with the plate side there are big holes (6) in comparison with the holes located on the side in contact with the components of the machine (Fig.6). Through the emptiness can be drilled using C0 2 laser, which can be programmed or exploit for generation of optical pulses preset duration.

Figure 7 depicts a supporting element, is made according to one aspect of the present invention. The image 702 illustrates through emptiness in supporting element, as they are visible from the top surface of the supporting element (i.e. from the side in contact with the leaf). The image 704 illustrates through emptiness in supporting element, as they are visible from the bottom party support element (i.e. from contact with parts of the machine). In this case the criteria through the void was an achievement oval pass-through cavities with the top open area in contact with the sheet-side relative to the opposite party or parties, in contact with components of the machine supporting element. The images 702 and 704 depicted the large openings (Fig.7) on the top or in contact with the sheet side compared with the holes on the bottom or in contact with components of the machine surface (Fig.7). These pass-through cavities can also be drilled with the use of CO 2 laser, which can be programmed or exploit for generation of optical pulses preset duration. As illustrated by figure 7, form holes is essentially oval compared with through emptiness, shown in Fig.6. Different factors and/or parameters (for example, drilling speed) can contribute to the difference in the form of pass-through of emptiness and open areas through voids (%) relevant to both surfaces to support the contact list and contact details of the machine.

In a similar example in Fig illustrated image through holes on both surfaces corresponding to the side in contact with the sheet, 902 and the side in contact with the components of the machine, 904, where the top and bottom holes through voids are essentially a rectangular shape. Similarly, according to another is given as an example of the implementation variant figure 9 shows the experimentally pictures from the cavities for the formation of through cavities according to another aspect of the invention. In some instances may be required through the emptiness of the increased size. For example, shown in figure 9 image 1010 and 1012 correspond through the voids, which are formed on the basis of various operating parameters, such as, but not limited by them, drilling speed, frequency, and the slow rate of frequency modulation, the output power of the laser, etc. Accordingly, form holes 1014-through cavities on the surface, corresponding to the image 1010, is essentially round, while the shape of the holes 1016-through cavities on the surface, corresponding to the image 1012, is essentially rectangular. One factor, among others, affecting the shape of the holes on the surface, may be scanning speed (i.e. mm/s) laser when the incident radiation is moved from one location to another for the formation of following through emptiness in supporting element.

In another embodiment, the structure supporting element contains contacting with the plate surface, which has a branched structure through voids, adapted to give non-woven product texture. Figure 10 shows examples of the cross-section structure 10 supporting element containing branched structure cavities or holes 11 containing small holes 10A and 10b on the contact sheet side 12, which is tilted so that they blend into the great emptiness 10th on the opposite side of the surface of 14. As shown, an extensive hole 11 may also be formed to include raised edges or flanging 16 adjacent to the circles of holes 10A and 10b. Although not figure 10 shows the raised edge or flanging can also be built adjacent to the circumference greater emptiness 10th on the opposite side 14 structure supporting element. Though the holes 10A and 10b depicted as merging into the void 10th, can be designed structure extensive cavities containing three or more holes, for example, 10A, 10b, 10C and 10A merging in great emptiness 10th, as shown in FIGU and 10S, whereby can be formed flanging ensuite or with smaller diameter hole in contact with the sheet side, or with larger diameter holes on the opposite side, or near the openings of both species. Emptiness can be direct (cylindrical or conical. For example, can be designed conical holes of various patterns, so that they are more and properly distributed on one side, such as contact with the sheet side, while through holes on the opposite side of contact with the machine components can be essentially aligned in MN, whereby, for example, improved drainage. Specified branched emptiness can be formed in the image of the structure or in layered basis. Emptiness can be formed in several ways punching or combination thereof, including drilling laser, mechanical punching and stamping. For example, voids can be formed by combining drilling laser with a stamping or punching laser etching/engraving, laser, etc.

This structure provides a large number of small holes in the structure supporting element, along with providing small long-term lengthening supporting element in the machine direction MN, as well as ensuring its Flexural rigidity in cross-machine direction MO. In addition, this structure can be adapted to, for example, form holes in the structure of the supporting element of a smaller diameter than the thickness of the substrate, without education, for example, clogged by contamination of holes.

Void larger diameter on the top surface and emptiness of a smaller diameter on the opposite side of contact with parts of the machine may have, for example, capture, shape, and/or orientation of fibers, located on the supporting structure of the element at the specified pattern and form of non-woven products with a large volume weight.

On figa-11TH contains a picture of the pads and corresponding grooves formed, for example, engraving or cutting, which marked areas are pads 62. On fig.11D represents emptiness or a hole 66 in contact pads. Textured images can be similar and repetitive, unequal and repetitive, as well as unequal and random. Pads 62 textured pattern include separate islets 62 or continuous site (not shown), and deepening 64 may include separate islets or continuous 64 platform. The shape of the island can be round, oblong, square, rectangular, trapezoidal, pentagonal, hexagonal, diamond-shaped in the form of a truncated cone, triangular or in the form of another polygon. On figa the figure, which has about 3 pads 62 per cm 2 . On FIGU and 11D drawn picture, containing separate rectangular pads 62 approximately 2.0 mm to 1.0 mm and continuous deepening 64 who share guides column 63A and 63b separate pads 62, about the size of 1.0 mm Other columns 63A pads 62 separated by grooves 64A approximately 1 mm

It should be noted, as mentioned above, that usually tapes used in obtaining of non-woven products, do not attach made them non-woven products characteristic structure that is different from the structure obtained by weaving drawings and weave. This structure is limited to the actual size of threads that can be used for weaving. "Structure" refers to changes in the basic mass and/or density of non-woven material, which is larger than the bulk and/or density in normal non-woven, and due to the usual changes. However, the "structure" can also refer to a texture, or pattern, or design of fiber non-woven cloth. Usually such "structured" - woven materials are soft and have a big volume weight with high absorbency. Structured nonwoven materials can be softer, more absorbent, and smaller the bulk compared with unstructured non-woven materials. Tape or sleeves according to the invention attach made it non-woven material required structure, the main mass, density, texture, tactile sensation and/or drawing.

As shown in figa-14G, in another variant of realization of the tape or the sleeve can be made of extruded or laminated films 91, which formed holes 96 to achieve the required permeability to air. Support structure (not shown) can be attached to one or both parties to one or both of the films a and 91b. These holes 96 may have different diameters of approximately 0,2 mm to 5,0 mm, hole 96 can be constructed in such a way as to be under different angles in relation to the plane of the support element. The holes 96 can be round, square, oval or any other specified form, such as a star.

As shown in figa, the position of the holes 96 on the surface supporting element may be uniform or accidental. In addition, the holes 96 can be allocated to specific density on the given section of the support item or evenly over the entire surface, depending on the requirements made of non-woven material. In addition, emptiness 96 may also be in the form of lines that cut or engraved inside a supporting element for the creation of graphics, such as logos. Supporting element can be made using one-layer or multi-layer polymer films a and 91b with reinforcement fiber or without reinforcement (woven or not). The structure supporting element can also be manufactured as "sandwich" with woven or non-woven layer, laminated between polymer films, as in the case of already disclosed in this description of the basics. Specified reinforcement can increase the mechanical stability of the fabric.

The supporting surface of the item can be engraved to create a relief of a surface, such as a cellular structure or another image, or it can be subjected to further processing for specific areas of application, such as the dissipation of static charge or Department dirt/mud. In addition, the supporting surface of the item can be engraved to create a relief surface for various drawings and logos.

As shown in fig.14F, use of the support item of the specified type provides a better reflection of energy when using process using water jets (hidrostatyba) compared to the standard woven ribbons. For example, the structure leads to improved plexus fibres, and also prevents the penetration captured fibers in the gap or space weave woven patterns. The result is improved plexus fibres and reduced plucking fibers, such as non-woven products better off with the tape indicated support element or transferred to the following position in the process.

As shown in fig.14G in contact with components of the machine side of the fabric is made with a relief surface, grooves or more monofilament 93 to create a higher degree of drainage.

On Fig shows a perspective view of continuous support element, or tape, or sleeves 1110, formed according to one implementation variant. According to the specified case, the tape or sleeve 1110 contains an internal surface 1112 and the outer surface 1114 and formed a winding spiral intermediate band 1116, made using one or more methods and systems discussed above. Intermediate band 1116 may be wound spiral, with many located next to each other and touching turns located essentially in the longitudinal direction around a cut tape or sleeves 1110, due to the spiral shape, which formed tape or sleeve 1110.

Given as an example of the way in which may be made the tape or sleeve 1110 described in the preliminary application at the U.S. patent №61/147637, filed December 12, 2008, and preliminary application for a U.S. patent №61/147637, filed on January 27, 2009, which are fully included in this description by reference. For example, the intermediate band 1116 may be striped or industrial packaging material, which are described in the present description. Because tape 1110 made by winding a spiral intermediate band 1116 and is not woven supporting element, its outer surface 1112 is smooth and continuous, and there are no designated weave, prevent surface woven supporting element was completely smooth. Preferably, the intermediate zone can be, for example, a strip of a thermoplastic material, such as film, foil or strapping tape, and can be made from any of the polymer, preferably of polyethylene terephthalate (PET). However, it can also be used for other materials, such as other polyesters (for example, polyethylene Naftalan (PAN) or polyster (SFC). Also can be used polyamides, polyetheretherketone (Cape peek). In relation to the layered material, consisting of one or two layers, each layer can be formed of the same or different materials. Film, foil or strapping tape can be uniaxial or dueno-oriented with a sufficient module and stability in both MN and MO to work as designed. In addition, film, foil or strapping tape can include reinforcement fibres MN or MONDAY, or both MN and MO, or in any random direction. Reinforcing fibres can be included in the extrusion process or pultrusion, where the fibers can be extruded or received by pultrusion together with the material, forming a film or foil. Reinforcing fibres can be generated from high-modulus of the material, such as, for example, aramids, including Kelvar ® and Nomex®, but are not limited, and can give the film or foil additional strength, modulus, durability and/or crack.

In addition, intermediate band can be covered with, for example, to improved removal of the sheet with the support element and/or the structural integrity of the intermediate band. The above structure can then be perforated and can be applied drawings previously described way.

Supporting element according to the invention may contain one or more extra layer on the top or bottom surface of the substrate only to ensure the functionality, but not for reinforcement. For example, as an additional layers can be used woven or non-woven materials, systems of threads in MN and MON, wound a spiral band of woven material of a width less than the width of a supporting element, fiber paintings, films or their combinations, and can be attached to any suitable substrate in a known way. Laminating thermoscreens and chemical bond are just a few examples.

Use of support element described in this description, can lead to the formation of non-woven products greater thickness and lower density compared to the products obtained using known from the prior art tissues. Large thickness and low density leads to the formation of a softer products with increased absorption capacity, both of these characteristics are very important.

Supporting element, or tape, or sleeve according to the present invention can be permeable to air in the range from 100 to 500 cubic feet per minute (2,83-14,15 m 3 /min). If necessary, additional layers. Supporting element can be made from any of the polymer, as discussed above, such as extrudable thermoplastics and rubber, in which cross-connections are formed at room temperature, under the action of UV and when heated, for example in the collections of polyester, acrylic or polyurethane copolymers. Materials are chosen so as to ensure the use of process hitrospleteniya, which can be used flow pressure up to 250 bar.

The supporting surface can be treated with a chemical coating for special applications, such as providing the dissipation of static charge separation dirt/mud, extending service life, etc. Use of support element of this type provides a better reflection of hydraulic energy compared to standard belt. Supporting element of this type improves tangling fibers in non-woven material and prevents the penetration of fibers in the gap/hole/void-aware tape, which can lead to loss of fibres or cause difficulties when removing non-woven material evenly with a supporting tape/sleeves, as can be seen in woven conveyor belts. The result is a best tangling fibers and less plucking fibers, as a consequence, improves the removal of the canvas with a supporting element or its transfer with the specified tape on another tape or to another position. Contact with the machine components party supporting element can contain surface relief or grooves or can be laminated monofilaments for a higher degree of drainage.

The end result is a superior tape or sleeve that function instead of the traditional woven tapes or sleeves made and give them nonwovens required physical characteristics, such as volumetric weight, appearance, texture, absorption capacity, strength and tactile sensations.
