Method of manufacturing hygienic paper products, device for such production and hygienic paper products

FIELD: textiles, paper, hygiene.

SUBSTANCE: proposed method of manufacturing hygienic paper products involves stages, in which a continuous paper sheet is supplied and moving this continuous paper sheet in the direction of its longitudinal stretch. A recurrent decorative structure is applied on the sheet relative to the longitudinal stretch of the sheet as the first design using the first drum. A recurrent functional structure is applied on the sheet relative to the longitudinal stretch of the sheet as the second design using the second drum. Simultaneous speed control of the repeating surface of the continuous sheet and phasing between the first drum and the second drum is performed, in order to phase the first design and the second design one relative to the other to obtain one and the same recurring spatial interrelation with each other on the whole longitudinal stretch of the continuous sheet. In this case the lengthening of the sheet is controlled due to contact zones during supply at the inlet and contact zones during discharge at the outlet before and after the stage of application of the first design and/or the stage of application of the second design and relaxing of the sheet after it leaves the contact zone during unloading at the outlet.

EFFECT: improved outward appearance of the product.

The technical field to which the invention relates.

The present invention relates to a method of manufacturing a hygiene paper product having a decorative structure and a functional structure, as well as to an apparatus for such manufacture and appropriate hygienic paper products.

Decorative structure in the context of the present invention provides for processing of any type, which gives an aesthetically pleasing figure hygienic product. That is, the decorative structure is applied on the hygiene product in order to obtain ornaments. Typical decorative element is the imprint, at least on one surface of hygienic paper products.

Functional structure, in contrast, are used to improve the properties hygienic paper products, i.e., functional structure may lead to an increase in the thickness, absorbency, bulk softness of the product, etc. Typical functional element is embossed ornament.

Sanitary paper product may be made of thin paper or non-woven cloth.

Thin paper is defined as a soft absorbent paper having a small weight 1 m2. In General, the weight of 1 m2one layer is chosen components 8-30 g/m2in particular, 10-25 g/m22multilayer articles of the thin paper is preferably a maximum of 65 g/m2and more preferably a maximum of 50 g/m2. The density of such paper in the typical case is less than 0.6 g/cm3, preferably less than 0.30 g/cm3and in a more preferred embodiment is in the range between 0.08 and 0.20 g/cm3.

Fabrication of thin paper differs from the manufacture of ordinary paper exceptionally low weight it 1 m2and considerably higher its rate of energy absorption stretching (see DIN EN 12625-4 and DIN EN 12625-5). Paper and thin paper also share the differences with respect to the modulus, which characterizes the properties of the chart "stress - strain" of these planar products, as a material parameter.

The high rate of energy absorption deformation of thin paper is the result of external and internal craigrownie. The first is implemented by compression of the paper web adhering to the dry cylinder effect of the creping doctor blade, and the latter is the result of the velocity difference between the two nets ("tissue"). This causes internal tears still wet, capable of plastic deformation of the blade due to compression and shear, resulting in increased compliance takoh the cloth under load compared to crepidomanes paper.

Moist cloth thin paper is usually dried by the so-called drying in Assembly Yankee, through the drying air (CERs) or impulse drying.

Fiber contained in a thin paper, are mainly cellulosic fibers such as wood fibers derived from technical cellulose (for example, sulfite and sulfate Kraft pulp), wood pulp (for example, wood residuals), thermomechanical wood pulp, chemical-mechanical pulp and/or chemical-thermomechanical pulp (TMDM). You can use wood pulp obtained as solid wood (hardwood)and soft wood (coniferous). Fiber can also represent or include recycled fiber, which can be attributed to any of the above or all of these categories. The fibers may be treated with additives, such as fillers, softeners such as Quaternary ammonium compounds, and a binder, such as basic substances, giving strength in a dry condition, or substance, which imparts strength in the wet state, is used to facilitate the manufacture of ordinary paper or for the correction of its properties. Thin paper may also contain other fiber types, such as regenerated cellulose in the window or synthetic fibers, increase, for example, strength, absorption, smoothness or softness of the paper.

Thin paper can be processed into a finished product from a thin paper in many ways, for example by stamping or layering it with getting layered products, coiled in a roll or stack.

The term "nonwoven" (ISO 9092, DIN EN 29092) is applicable to a wide range of products in terms of their properties are between paper products (see, for example, DIN 6730, may 1966) and cardboard (DIN 6730), on the one hand, and textiles, on the other hand. In connection with obtaining nonwoven materials using a large number of very different technological processes, such as appropriate ways of pickup on the air or centrifugal netting, and also wet pickup. Nonwovens can also be called textilejobsnet composite materials which are flexible porous fabric, which cannot be obtained by classical methods of interlacing of warp and weft or catlike. In practice, non-woven fabrics are produced by interlacing, cohesive or adhesive bonding fibers or a combination of these methods. Non-woven material can be formed from natural fibers, such as fibers of cellulose or cotton, but may also consist of synthetic fibers, such as the ox is the people's army of polyethylene (PE), polypropylene (PP), polyurethane (PU), a complex of the polyester or regenerated cellulose or of a mixture of different fibers. The fibers may be present, for example, in the form of endless fibers of the pre-made fibres of some finite length, when synthetic fibers are produced on site, or in the form of staple fibers. Thus, non-woven materials in accordance with the invention can consist of mixtures of synthetic and cellulosic fibrous materials, such as natural vegetable fibers (see ISO 9092, DIN EN 29092).

Hygiene or cleaning products include mainly any type of thin paper, creped in the dry state, plain paper, creped wet, and cellulose or packing, or all types of nonwoven materials, or combinations thereof, layered materials or mixtures thereof. Typical properties of these hygiene and wiping products include the ability to ready and able to absorb the energy of tensile stresses, the drape of such products, reasonable flexibility like textiles, as well as properties, which are often called the volume softness, high surface smoothness and a high specific volume with a visible thickness. Desirable as a higher capacity to absorb the liquid and depending on the application at mlima strength in wet and dry condition, and attractive appearance of the outer surface of the product. These properties - among others - allow the use of the hygiene and cleaning products, such as cleansing a cleaning means, such as paper or non-woven wiping means wipes for cleaning windshields, industrial rags, kitchen paper, etc. as sanitary products, such as toilet paper, paper or non-woven handkerchiefs, household bedding, towels, etc. as cosmetic wipes, for example, for a person, and as pads or diapers, and just mentioned products are just a few of those, as possible their use. In addition, hygiene and cleaning products can be dry, moist, soaked or pre-processed in any way. In addition, hygiene and cleaning products can be stacked, laid or placed separately stacked in the foot or roll up into a roll, connected or not connected in any convenient way.

In accordance with the above description of the considered products can be used for personal or domestic use and for commercial or industrial applications. They are designed to absorb liquids, moratlity for decorative purposes, for packaging or even directly as the carrier material, which is usually in medical practice or in hospitals. In the context of their wide range of hygiene and cleaning products are now considered everyday products.

Prior art

Generally speaking, it is known that hygienic paper products contain functional and decorative structure. In particular, these hygienic paper products first carry out printing, and then embossed. In an additional step, hygiene paper product, which is typically made of a continuous, cut into individual segments, are desirable for the formation of a single sheet, or provide the perforations, forming a line of weakening, which provides the user the possibility of separating a single sheet from roll, such as roll of toilet paper or kitchen roll towels. Between treatments, namely, printing, embossing and cutting or punching, synchronization is typically not provided. That is, functional or decorative changes continuous web during processing depend on the specific steps of repetition, which are usually predetermined by the equipment used and therefore unequal.

For example, the step of repeating for Deco is investing printing can be 378 mm, i.e. printed decorative piece is 378 mm and repeats every 378 mm, however, the embossment is repeated, for example, every 30 mm. Therefore, the location of the embossed imprint on the ornament appears to be different for each single sheet, because the steps of repeating these treatments are not the same. The same thing happens if the segment repeat perforation (length list) also appears to be different, that is, in the above example is 256 mm, Thus, the location of the imprint and embossed ornament is different on every single sheet, because the period of repetition of the perforation does not coincide with the periods of repetition of other aspects. As shown in figure 1, this leads to a distortion of printed images by stamping and punching holes around the ornament. Single sheet 1 of hygienic paper products includes embossed figure 2 and the printed pattern 3. In addition, a single sheet is cut or perforated along the line 4 compartments. Due to the fact that the steps of the repetition of these three elements - embossed ornaments, prints and perforation - not the same, the body of the animal printed, for example, is superimposed on the embossed ornament and is partially cut off or intersected, respectively, line 4 branches.

To improve visually vos is Rinkeby appearance, in the document EP-A-0958112 described synchronization or coordination of one of the functional structures or decorative patterns by cutting or punching. In this context, the spatial relationship between one figure and the lines end (i.e. the lines that separate one sheet from another either through perforations or lines of weakening or cutting) set by regulation or step of drawing, or the step of applying the perforation or cutting, the sheet is transported at a constant speed.

In the document US-A-3594552 described system and method of synchronization replaceable single nodes printing unit with each other. All the used printing cylinders rotate in unison, with the same peripheral speed, and the steps repeat for each printing cylinder are the same. Any failure in synchronization detected by the scanner detects the reference mark on the canvas, where a print is produced, and a rotary digital encoder. If an error is detected, it is corrected by compensating device.

So, to ensure the coordination of the two images, the image size, i.e. the length in the direction of movement of the blade (in the feed direction of the machine), must be agreed with the relevant processes. In a typical condition known equipment, what oterom used a combination of two shafts, the length of the pattern printing or embossing is a predetermined shaft diameters, circumferences of the shafts or integer lengths of a circle, respectively. For example, a typical circumference of the shaft of the printing press is 756 mm Therefore, the length of the figure, a pre-defined by the circumference of the shaft, you can choose from the values 756, 378 or 252, etc., i.e. the circumference divided by some integer, will determine recurring segments. Maximum recurring segment is 756. The same reasoning applies to the embossing, in which the engraved shaft for stamping, made of stainless steel and having a certain diameter, determines the maximum recurring segment and acceptable whole division. For example, you can use the engraved roller for embossing with a diameter of 530 mm, having a circumference 1664 mm

Theoretically, the selected duplicate segments for printing and embossing, must be identical in order to obtain consistent decoration printing and embossing. When the above-mentioned shaft sizes repetition printing through 75,6 mm (10 repetitions per revolution) would be combined and coordinated with repeat stamping through 75,6 mm (22 repetitions per rotation), respectively. However, this theory is applicable only in case you neglect some technologies what their parameters.

In particular, for processing the leaf material required tension tight, which is greater than zero, so you can pull the fabric forward and to control the posting of the canvas. In addition, the printing process, as well as the stamping process requires the blade speed, which is aligned with speeds of shaft surfaces, and provides for the giving of such speed. That is, there is no slippage. In addition, as part of the process of printing and embossing change the extension of the canvas. Moreover, known systems manage the tension in such a way that changes the dependence of stress - strain in the base of the canvas. This is especially in case of highly tensile fabric - leads to a change in elongation at constant tension. So, over time, will be introduced the minimum error and/or difference of repeating segments or extensions cloth or speeds. For example, after 1000 repetitions in the above example, the parameter 75,6 mm, a small difference amounting to several micrometers, will be made in less than two minutes. Figure 2 schematically illustrates such a mismatch, which is also called "the care of the picture."

Summary of the invention

Given the above, the technical problem underlying the present invention is, h is usually used to overcome the problems and theoretical limitations, typical of the known technical solutions, and to develop a method of manufacturing a hygiene paper product, the visually perceived appearance of which is enhanced due to matching decorative patterns and functional structure, as well as to develop a device for carrying out the method of manufacture and appropriate hygienic paper products.

The technical problem is solved by the object of the invention is described in the independent claims. Additional embodiments of you can understand from the dependent claims.

In accordance with the present invention a method of manufacturing a hygiene paper product includes the steps, which features a continuous paper web, moving a continuous web in the direction of its longitudinal stretch, causing repetitive decorative structure relative to the longitudinal stretch of the fabric in the first picture on the canvas through the first shaft and cause repetitive functional structure relative to the longitudinal stretch of the canvas as the second picture on the canvas through the second shaft. To align the first image with the second picture, that is to stateroute the first image and the second image relative to each other so that the button they have the same repetitive spatial relationship relative to each other around the longitudinal course of continuous web, carry out simultaneous speed control of repetitive surface of the continuous web and the phasing between the first shaft and the second shaft. In other words, you can control, for example, the speed of the surface of the continuous web on the first shaft and/or the second shaft.

In a preferred embodiment, the processes of printing and embossing is carried out close to each other, either on the stage of applying a decorative structure or stage of deposition of functional patterns is carried out in the processing chain after another of these stages in the direction of movement of the blade. One of these processes is carried out in the processing chain after another, set up with a fixed excess (for example, 2%) speed, and the steps repeat equipment (recurring segments) of both processes, namely phase, which is in the processing chain before the other, and phase, which is in the processing chain after mentioned, do differ in a fixed ratio, consistent with the above-mentioned excessive speed and depend on it. That is, repeating segments, pre-defined equipment both processes are chosen so that the conditions mentioned excessive speed both printed patterns are consistent. Regulation step of applying a decorative structure in order to stateroute PE the first picture and the second picture relative to each other around the longitudinal course of continuous web, carry out due to the phase shift, for example, via a gearbox or actuator.

In a preferred embodiment, the elongation of the fabric is controlled by the contact zone at the feed inlet and the discharge outlet before and after the step of applying the first pattern and/or the step of applying the second picture and relaxation of the fabric after it leaves the contact zone at the discharge outlet. In particular, two additional stations with contact areas in front of one of these two processes and after that create a specific and controlled elongation of the fabric during this process and thereby ensure the running speed of the surface of the continuous web in the implementation process. In a preferred embodiment, the actuators at stations with contact areas connected to the first or second shaft, respectively. Thus, the sheet speed at these stations with the contact zones is the same, and the cloth is subjected to the appropriate process without changing its tension or elongation. Painting relaxes after leaving the zone of contact when applying for the entrance. Due to this composition on an elongated fabric can be printed, for example, the printed pattern that is present on the print shaft, with repetitive lengths of 200 mm When the elongation of, for example, 5%, printable picture is and the canvas will be reduced, for example, to a length of about 190 mm after relaxation. This leads to a regulated recurring segment, although printing equipment and printing process as such are not regulated. Therefore, in the context of elastic elongation of the considered system can also be used for correcting the basic mismatch between repeated segments of printing and any other recurring segments, such as stamping, punching, etc. Typical adjustment range for products of thin paper will be from 0% to 20%, and in more preferred embodiment, from 0% to 10%, and in the most preferred embodiment, from 0% to 5%. For example, range from 0% to 5% in the case of a typical household towels will ensure the regulation of repeating segments in the range between 0 mm and 12 mm By controlling the elongation of the fabric in one stage compared to other stages can indirectly control the speed of the shaft surface at the appropriate stage, or to provide an indirect effect on this speed by controlling the speed of the surface of the continuous web by extending the canvas at the appropriate stage.

In a preferred embodiment, the method further includes the control of the speed ratio between the step of applying the first pattern and the step of applying the second picture, and targetirovanie between the step of applying the first pattern and the step of applying the second pattern through the body carry out feedback control of the position of the continuous web relative to a reference point. For example, a sensor, say - shooting camera, detects the reference mark, preferably printed on braquenie part of the continuous web, and gives feedback on the difference between the target distance and the measured distance between the two marks. This signal can then be used for automatic adjustment of speed ratio drives of both processes. In addition, this method of feedback control, you can control the correct phasing between the two processes. Acceptable means of feedback control is known to the person skilled in the art so that a detailed description is not required here.

In a preferred embodiment, the method additionally includes the stage at which carry out repetitive perforating continuous web transversely to its longitudinal stretch and control the phasing between the stage of punching and stage carried out in the processing chain before the step of punching, when viewed in the direction of movement of the fabric, by means of the sensor to phasing the perforations with the first pattern and/or the second pattern and to have the same repetitive spatial relationship of the perforations relative to the first and/or second pattern along the entire longitudinal prot is the supply of continuous web. This step of the method required, for example, if you have to produce sanitary paper product as the final product is presented in the form of a roll from many individual sheets. This roll contains many sheets separated by lines of weakening, such as lines of perforations. For example, the roll may have an overall length between 10 m and 20 m

The perforation of continuous cloth preferably phase in a controlled manner by means of the sensor signal, described above, as part of the feedback control. The processes of punching and cutting fairly uncritical with regard to speed and in a typical case are excessive - in the amount from 2% to 30% speed in order to achieve clearly better processes. Thanks to high-speed flexibility, automatically controlled phasing is sufficient to achieve coordination punching printing and/or embossing.

In a preferred embodiment, the step of applying the first pattern on the continuous canvas carry out printing, while at the stage of applying the second picture on the canvas carry out the embossing. In particular, the print gives a decorative structure, namely the figure, while the embossing gives a functional structure, for example, increasing the thickness of the product, absorbing the way the spine, bulk softness, etc.

In addition, during the step of applying the first pattern on the canvas, you can apply a functional coating. Functional coatings can be, for example, abrasive coatings to improve the abilities of towels to wipe dry. In the case of the above process, spots functional coatings can be applied to certain areas of the surface of the product, for example, only the peaks or troughs embossed product.

Installation for the manufacture of hygienic paper products includes means for feeding a continuous paper web, means to move the continuous web in the direction of its longitudinal length, the first node for applying a first pattern and a repeating decorative patterns on paper, and the first node has a first shaft, a second node for applying the second figure in a repeating functional structure on the paper web, and the second node has a second shaft. For phasing of the first pattern relative to the second pattern so that they have the same repetitive spatial relationship relative to each other around the longitudinal course of continuous web, the installation further comprises means for simultaneously controlling the speed of the surface of the continuous web and the phasing between the first shaft and the second shaft.

In a preferred embodiment, either the first node or the second node is placed in the processing chain after another of these nodes, when viewed in the direction of movement of the continuous web, and both nodes are close to each other. A node in the processing chain after another, has some fixed redundant (for example, 2%) speed, and the step of repeating node in the processing chain before the other, differs in some fixed excess ratio-dependent mentioned fixed excessive speed. That is, the repeating period is chosen or adjusted so that, theoretically, to guarantee bringing both drawings in accordance considering the velocity difference of the surfaces resulting from the aforementioned excessive speed. To stateroute the first image and the second image relative to each other around the longitudinal course of continuous web, the installation further comprises means for phase shift, and this means a phase shift connects the drives mentioned node in the processing chain before the other, and the above-mentioned node in the processing chain after another. By means of the phase shift may be a gearbox or actuator.

In a preferred variant implementation is tvline, the installation further comprises two additional stations with contact areas, namely the area of contact when applying for the entrance to one of the above first or second nodes and the area of contact during unloading at the output after the above site, if you look in the direction of movement of the continuous web, and this painting relaxes after it leaves the contact zone at the discharge outlet. Station with contact areas can be formed by a structure providing an S-shaped path and is provided with an actuator and the actuator at the stations with the contact areas can be connected to the first or second shaft, respectively. Due to this layout, you can control the elongation of the fabric within the respective node before which and after which there are two stations with the contact areas, and thereby indirectly control the speed of the surface of the continuous web.

In a preferred embodiment, the installation further comprises a body carried out with feedback control to use it to control the speed ratio between the first and second nodes and/or phasing between them.

In the preferred embodiment, for manufacturing a hygiene paper product in the form of a roll having a number of separate sheets, installation further comprises a node preparerow the tion, designed for repeated punching continuous web transversely to its longitudinal stretch. The site of perforation is provided in the processing chain after the first and/or second node, when viewed in the direction of movement of the blade. For phasing between the site of perforation and the first and/or second node in the processing chain before the site of perforation is provided to the sensor. This sensor may be part of the aforementioned means of feedback control by detecting the reference mark, preferably printed on braquenie part of the continuous web, and giving feedback on the difference between the target distance and the measured distance between the two marks. This signal can then be used to automatically control the phase.

In a preferred embodiment, the first node contains the node print, printed with the shaft, and the second node contains the node stamping, engraved with the shaft for stamping.

The present invention also suggested that the product obtained by the above method or the above-mentioned installation.

Hygiene paper product according to the present invention preferably has the form of a continuous web and contains regarding this continuous web of the first pattern with a repeating decorative p is the established levels and the second image with repetitive functional structure. The first image and/or the second image are repeated and an adjustable position along the longitudinal length of the blade. That is, the corresponding figure is repositioned in a certain place on the canvas relative to a reference mark on the canvas, such as perforations or other appropriate pattern.

The proposed sanitary paper product preferably has the form of a continuous web that is present in the form of a roll, and contains the first image with a repeating decorative structure relative to the longitudinal direction of the blade, and a second image with a repeating functional structure relative to the longitudinal direction of the blade. This is a hygiene paper product differs in that the first image and second image, respectively, agreed or paserovany relative to each other so that they have the same repetitive spatial relationship relative to each other around the longitudinal course of continuous cloth.

Sanitary paper product preferably contains many sheets made with the possibility of separation from each other by perforations made repeated across the longitudinal stretch canvas, and this is the perforations agreed or paserovany relative to the first pattern and/or the second picture so that have the same repetitive spatial relationship relative to the first and/or second pattern around the longitudinal course of continuous cloth.

For example, the first and second images can be stripes, perpendicular to the longitudinal stretch of the fabric, while the first image and the second image do not overlap.

Alternatively, the first pattern may surround the second picture, and Vice versa. For example, the first figure is essentially evenly distributed essentially over the entire surface of hygienic paper products and leaves free the space occupied by the second figure.

The sprocket holes are mostly not intersect the first pattern and/or the second image. If the sprocket holes are also aligned with the first and second picture, it is possible to obtain hygienic paper products, in which each sheet of multiple sheets separated from each other perforations, has the same visually perceived appearance.

In a preferred embodiment, the first image is printed, and the second figure is embossed pattern.

The present invention provides greater flexibility in relation to the visually perceived ornament hygienic paper products. Using altoadige invention can negotiate different processing or drawings so if you can get a hygiene paper product which has improved visually perceived appearance, and you can also give a typical desired product characteristics and properties and to provide a simple manufacturing.

Detailed description of the invention

Figure 3 presents a schematic representation of the preferred option the installation corresponding to the present invention. The system includes a host 10 unwinding for feeding a continuous paper web at the appropriate stage of manufacture. Node 10 is unwound from the unwinding unwinding roll 11, and with him is the presentation of the material in the form of a continuous paper web 12 at the corresponding node. Unwinding the roll is large roll of paper recycled in numerous individual hygiene products in the form of sheets or rolls. Different unwinding the rolls have different properties that affect the transport of sheets through the installation. For example, the magnitude of the tension in the sheet as it passes through the install, often undergoes significant changes between the unwinding rolls. When these properties change, the same thing happens with the approval of the first picture with the second picture and/or perforation. However, by setting corresponding to the present invention, it is possible to avoid this problem.

In the example shown is continuous in the relative first transported to the site 13 printing. To site printing, i.e. in the processing chain before node print, when viewed in the direction of movement of the fabric through the installation, provided by the area 14 of contact when applying for the entrance, made in the form of designs, providing an S-shaped trajectory, and formed by two rollers 14a, 14b. Outside of the node 13 printing, i.e. in the processing chain after the host print zone 15 contact with the discharge outlet is in the form of a design, providing an S-shaped trajectory, and formed by two rollers 15A, 15b. Site seal is located between the zone 14 of contact when applying for the entrance and zone 15 contact with the discharge outlet and contains four printing cylinder 16, 17, 18 and 19 and one pressure roll 20 for all four printing cylinders. As will be obvious, the host print 13 is a node in four-color printing and therefore contains four printing cylinder. However, it is also possible other traditional layout of the site and print a different number of colors, which is obvious to a person skilled in the art. The drawing shows that the continuous fabric is transported from node 10 unwinding to the node 13 printing, that is, as shown in the drawing, a continuous canvas 12 moves from left to right. Therefore, when viewed in the direction of movement of the continuous web 12, the zone 14 of contact when applying for the entrance is a technologist who worked the chain before node print, the zone 15 of the contact when the discharge outlet is in the processing chain after the node is printed.

Leaving the area 15 of the contact at the discharge outlet, the leaf is transported to the site 21 embossing. The node 21 embossing contains engraved shaft 22 for stamping and the corresponding pressure roll 23. In the processing chain before the engraved cylinder 22 for stamping, if you look in the direction of movement of the blade 12, is a sensor 24, which is part of the means of feedback control (not shown). The sensor 24 is arranged to detect the reference mark printed on a paper cloth, preferably with the help of unit 13 printing, and more preferably at braquenie part of the band 12, which is later cut to give the fabric the desired shape. Means of feedback control calculates the difference between the target distance and the measured distance between two reference marks on paper cloth 12. On the basis of this signal is adjusted, if necessary, the speed ratio of the driven printing cylinders 16, 17, 18, 19 and engraved cylinder 22 for stamping, to correct any deviations. In addition, the actuators engraved cylinder 22 for stamping and printing cylinders 16, 17, 18, 19 are connected via a gearbox or actuator acting what about the "master - slave".

As is clear, the node 21 embossing contains a second engraved shaft 25 for stamping and the second pressure shaft 26. For example, the second continuous canvas 27 to be embossed can be submitted in the node stamping, and then layering on the first continuous fabric 12 to ensure the manufacture of laminated paper products. Naturally, you can use an alternative layout of the site embossing, well known to the person skilled in the technical field.

After embossing the paper web is transported to the site 28 perforation, perforation containing the shaft 29 and the pressure roller 30. Front hub 28 hole-punch can be located additional station 31 with a contact zone containing two roller 31A and 31b. After punching, the continuous canvas 12 or, in the event that there is a layering two sheets, multi-layer cloth 27 is wound with node 32 rewind. Thus, it is possible to provide the final product in the form of rolls, such as rolls of toilet paper or rolls of kitchen towels. Alternatively, instead of the site of perforation can be provided node is cut. In this case, the final product has the form of a single sheet, such as diapers.

Referring now to figure 4, note that here shown schematically to nonoka zone 14 contact when applying for the entrance and zone 15 contact with the discharge outlet, between them lies only one zone 33 of the printed contact. Area 33 of the printed contact is limited printed shaft 33a and the holding shaft 33b. Drives all three zones 14, 15 and 33 of the contact connected to each other, and the blade speed at these stations with the contact areas are identical, so that the blade goes through the process without changing the tension or stretching of the cloth. After leaving the zone 15 of the contact at the discharge outlet of the fabric relaxes.

As you can see from the corresponding plot of the velocity and tension, shown in figure 4, on a slender canvas you can print printable ornament, having, for example, repeating segments of 200 mm on the print cylinders. The fabric undergoes elongation between the zone of contact with the feed inlet and the contact zone at the discharge outlet and, leaving the contact zone at the discharge outlet, again relaxes. When the elongation of 5% printable ornament, repeated every 200 mm, which is printed on an elongated canvas, will be reduced to approximately 190 mm on the sheet as it leaves the zone 15 of the contact at the discharge outlet. Thus, in the context of elastic elongation, the system can also be used for correction of basic errors between repeated segments of printing and any other recurring segments, such as in the preferred embodiment, OEM home button Flex cable is trivsam embossing and/or perforating. Typical adjustment range for products of thin paper will be between 0% and 20%. As an example, note that the range from 0% to 5% for a typical household towels will provide regulation recurring segment by an amount in the range between 0 mm and 12 mm, length of blade 12 regulate by means of actuators of the respective stations with the contact areas. Arrow 34 indicates the direction of movement of the blade 12.

Figure 5 shows one sheet of hygienic paper products in the form of a continuous web intended for winder roll, or hygienic paper products, which as such represents this sheet. Sheet 1 contains functional embossed figure 2 and the decorative printed pattern 3. As becomes evident from figure 5, figure 2 and figure 3 are combined, i.e. both picture agreed or paserovany relative to each other. In addition, the sheet is separated by cutting along the line 4, which is provided by the perforations. Therefore, the present invention ensures repeatable manufacture of tiles that are embossed figure 2 and the printed pattern 3, phased relative to each other so that you can produce a lot of leaves, having repeated the same spatial relationship of the drawings relates the flax each other. In particular, the present invention ensures production of hygienic paper products in the form of a roll, containing a number of sheets separated from each other perforations 4, positioned across the longitudinal stretch fabric, forming roll, each sheet has the same spatial relationship between the embossed pattern 2 and the printed pattern 3, and the sprocket holes are made such that these drawings 2 and 3, it bears repeating, have the same spatial relationship on the surface of a single sheet.

The above explanation becomes even more evident from Fig.6.

Now will be described more detailed description of the operation corresponding to the present invention. As becomes obvious from figure 3, the processes of printing and embossing are close to each other. As mentioned above, the actuator node print, and host stamping is connected through the phase-shifting gearbox or with the electronic device through the intermediary of actuators acting on the principle of "master - slave". The stamping process is configured to operate with a fixed excess, for example, 2%speed. That is, the speed of the engraved surface of the shaft 22 for stamping and the pressing shaft 23 aligned with said fixed excessive speed. In addition to regular equipment drawings, provided both processes, i.e. repeated segment in the printing process and repeatable segment in the stamping process, differ in some fixed ratio set in accordance with the above-mentioned excessive speed. In other words, the repetition of the fingerprint does not match the repetition embossed ornament, but step repetition in both cases adjusted in accordance with the excessive speed of the surface of the respective shafts. In addition, the regulation of the press in accordance with embossment carry out due to the phase shift via a gearbox or actuator.

A fixed speed ratio occurs simultaneously with a fixed tension, the latter is not regulated. However, different specifications and different source materials introduced by the unwinding roll 11, require different tensions of fabric for optimum quality products and reliable operation. Furthermore, the said fixed ratio also determines the difference between repeating sections between printing and embossing, as mentioned above. Whatever the case, any error in the repeating segment will "go the drawings, shown in figure 2. Since it is difficult to define segments of repetition in a typical node, where s is s is made from steel to rubber, in accordance with the present invention provide additional regulation by means of two additional stations 14 and 15 with the contact areas located in front of the equipment for the printing process and after such equipment. As becomes evident from figure 3, the continuous paper web is supplied to the node 13 print and gets into the zone 14 of the contact when the flow at the inlet, passes through the print zone of contact, limited printing cylinders 16, 17, 18 and 19 and the holding shaft 20, and then leaves the site 13 printing over an area of 15 contact during unloading at the output. In between these two zones 14 and 15 of the contact can be controlled by movements of the blade in order to adjust repeating segments in the processes of printing and embossing. In fact, as mentioned above, by lengthening the blade 12 within the printing process can be adjusted recurring segment print, adjusting the actual recurring segment, a pre-defined equipment, namely by the circumference of the printing roller and the appropriate choice of repeating segments. For example, printable ornament with lengths of 200 mm on the printed cliches, that is, repeating segments, pre-defined equipment, can be printed on an elongated leaf in the lengthening of the paintings of 5% compared to its unstretched condition, thus the m that printable ornament will decrease to about 190 mm on the canvas after the relaxation, that is, after the fabric 12 will leave the area 15 of the contact at the discharge outlet. The lengthening of the blade is adjustable connected to each other by the actuators stations 14, 15 and 33 with the contact zones.

In addition, during the process of printing on paper cloth over a predefined period of printed control mark. The sensor 24 detects these benchmarks, but a means of feedback control compares the target interval from the measured distance between two reference marks. On the basis of this signal, an automatic correction of the ratios of the speeds, guaranteeing the desired phasing between the two drawings. Through this tool, the feedback control can be automatic correction and automatic control in order to achieve proper stretching of the cloth printing and embossing, as well as phasing between printing and embossing.

In addition, the above-mentioned sensor signal phase perforating a thin paper web and manages the perforation. The processes of punching and cutting fairly uncritical with regard to speed, with typical systems operate with a surplus, to the extent of from 2% to 20%, speed to achieve clearly the best p is acesso. Thanks to this high-speed flexibility automatically controlled phasing is sufficient to achieve coordination punching printing and/or embossing. That is, due to the signal received from the sensor and the body of the feedback control, speed control node punching is simple, ensuring alignment with the printing and/or embossing.
