The method comprises the steps of applying color to a first embossing roller, passing the at least two layers through a press nip formed between the first embossing roller and a second embossing roller, and embossing the at least two layers in the press nip and simultaneously printing the color on a surface of the embossed layers, the surface defining an outer surface of the tissue. The device comprises a first embossing roller and a second embossing roller, the first and second embossing rollers forming an embossing press nip between them, and an ink application device. The ink application device is arranged to apply ink to the first embossing roller in such a position that the ink in the press nip is printed on the outer surface of the layers being embossed simultaneously with the embossing of the at least two layers.

Description

The present invention relates to a method and a Device for producing a printed ink pattern for a tissue product that has at least two layers, and a tissue obtained by such a method. As used here, the term "tissue" is as so-called non-wovens and textiles too understand. In particular, the invention relates to hygiene and other products, such as napkins, Handkerchiefs, kitchen towels, facial tissues, Toilet paper, wipes and the like.

Products of the above type have two or more Lay on, and can, for example, to give them one for the Users attractive, pleasing appearance too lend, be provided with a pattern that consists of a or several colors, the pattern overlapping part or all of the area of the tissue product extends.

State of the art

It is with tissue products such as Hygiene products known, various To provide product designs. Examples include colored napkins made from tissue material webs are made and entirely with one or more colors are colored. In this case, the color is already in the Manufacturing process of the tissue web introduced.  

Other processes use tissue printing Products on one or both sides. This is in all of them Known tissue areas, including toilet paper, Household rolls and handkerchiefs. In this case, a Tissue web during the processing of the Material web to the end product with ink or the like printed. There are several ways to do this the color design, for example by mixing the inks or similar with the order (so-called process printing) or by simply printing on previously mixed colors.

It should be noted that in the context of the present Invention the term ink should be understood that it contains pigments, ink, dye, toner or any other coloring agents.

A laminate of paper or the like is from GB-A- 2255754 known and comprises two layers, at least of which a transparent, shaped and at least in some areas the embossing is attached to the other layer. Between the layers, a colorant is provided such that the Coloring is visible where there are points of the first Leaf is in engagement with the second leaf. The CA-A 2124240 teaches a multi-ply tissue that has two or more has inner ply surfaces, one or more of which a coloring or pattern that is supported by at least one the outer layers of the tissue is visible. A special Disadvantage with regard to tissue products of the kind resulting from these both publications are known, it is that the by printing the colorant on an inner surface of pattern of one or more of the layers Gives the impression of being faded, which is not always the case may be desirable. There is also consideration the fact that the printed pattern is on a inner surface of the tissue, no need for a correlation of the printed areas with other parts of the tissue layer (such as the  embossed areas) to achieve a perfect print because due to the location of any mistakes to a certain extent Degrees hidden and not easily recognizable.

Other printed products that have the pattern on the Printed on the outside surface of the tissue have one more or less good quality, but they all have one thing in common, that one printed on an outer surface of the product Pattern is distorted, d. H. the pattern is insufficient Grid accuracy in that the printed Elements of the pattern do not match the previously designed one Grid pattern or, if desired, to the embossing pattern correlate. This is because it is difficult to Print exactly on the other elements of the tissue web to correlate, for example the embossing or Perforations or other printed patterns on the Web. Deviations of several tenths of a millimeter are not uncommon at the moment. This problem stems from that the printed pattern in a separate process must be applied, for example before or after Embossing process. Fluctuating tensions in the tissue Web of material cause the printed pattern "slips" so that the visual impression of the printed Sample of the product and consequently also of the whole Product deteriorates significantly.

presentation

On the basis of the above, the present invention made to solve the problem, a process for Manufacture a tissue product to provide that free of the above disadvantages is a clearly visible one printed pattern and still an optimal Has grid bracket. It is another job of the present invention, an apparatus for manufacturing of such a tissue product and a tissue product without to provide the above shortcomings.  

These tasks are solved by a procedure that the Features of claim 1, with a device the features of claim 12 and a product with the Features of claim 29 or 30. Advantageous others Embodiments are in the dependent claims specified.

The inventive solution to the above problems exists in printing at the same time as embossing the Tissue product to perform so that a perfect Correlation between the printed and embossed patterns consists. This also provides the advantage that Lower the number of process steps required to manufacture the End product are required. Consequently, the present Invention by a so-called colored embossing realized, in which printing and embossing steps at the same time be carried out. For example, one or both of the Embossing rollers continuously wetted with ink before in the Press nip between the two embossing rollers the actual Embossing step is carried out. In this case, when the embossing protrusions on the embossing roller into the tissue Material web of the at least two the tissue product the resulting layers to press the layers together the desired positions at the same time the transition of the Ink held without any risk of the previous one Systems of known "slipping". Hence one or both outer sides of the embossed tissue product are included printed on the designed pattern so that an exact Correlation of the printing areas with the embossing areas consists. The grid accuracy can be optimized accordingly although in a comparatively simple way and way without complicated processing steps or the Need for additional complex machinery is realized. Instead, the embossing of the tissue not only used in addition to printing, but above it  for a correct positioning of the print pattern at the desired location.

In addition, contrary to already known implies Uses and products the inventive method and the inventive device that it is not necessary to use an adhesive, especially not to a connection between the layers of the tissue product manufacture. Since the ink on the exterior of the tissue Product to a precise relative to the embossing pattern positioned way is applied clear and distinctive color pattern high Definition achieved.

The present invention is now preferred exemplary embodiments with reference to FIG the accompanying drawings, in which:

Description of the preferred embodiments of the invention

The apparatus, method, and product according to the present invention will now be further described, initially with reference to FIG. 1.

In Fig. 1 reference numeral 1 designates an ink reservoir, which receives an adequate supply of liquid typically Ink 3. The ink reservoir 1 is connected to an ink supply chamber 5 via lines suitable for the ink. The ink supply chamber 5 in turn comprises one or more doctor blades 7 . In combination, the ink reservoir 1 , the ink supply chamber 5 and the doctor blade 7 supply an ink transfer roller 9 with the desired amount of ink and consequently form a supply system or a supply unit for the next adjacent element. Such an ink application system is generally referred to as a doctor blade system. Typically, the ink is applied to the entire surface area of the ink transfer roller 9 and the desired amount of ink applied is adjusted via a first doctor blade, a second doctor blade being provided to remove unused ink from the ink transfer roller 9 back to the ink reservoir 1 .

In the embodiment of Fig. 1, the ink transfer roller 9 is arranged so that it contacts a first embossing roller 10 . The ink applied to the surface of the ink transfer roller is transferred to the first embossing roller 10 . The materials selected for the ink transfer roller 9 and the first embossing roller 10 can enhance this transfer effect. Typically, the 10 materials are selected for the first embossing roller that best achieve the desired embossing effect. The material selected for the ink transfer roller 9 will therefore have to match the materials selected for the first embossing roller 10 , while at the same time offering the desired controlled transfer effect. Suitable materials for these rollers are stainless steel, typically stainless steel, for the first embossing roller 10 and a flexible or resilient material such as rubber for at least the surface of the ink transfer roller 9 .

As can further be seen from FIG. 1, the first embossing roller 10 is arranged so that it forms a press nip with a second embossing roller 12 , through which the number of tissue layers desired to form the tissue 20 runs in the direction indicated by an arrow.

The arrangement of the first embossing roller 10 and the second embossing roller 12 relative to one another and the layers of tissue 20 running through the press nip between these two rollers can be better seen from the enlarged schematic detail I of FIG. 1.

In detail I, the radii of curvature of the first and second embossing rollers 10 , 12 have been simplified and are shown as straight lines.

From detail I it can be seen in particular how the first embossing roller 10 is provided with projections 14 and recesses 16 . In the particular embodiment shown, the second embossing roller 12 is a smooth roller, in other words it is not provided with any projections or recesses and can be referred to as a counter-pressure roller for the first embossing roller 10 . Of course, a profiled second embossing roller 12 can be used instead if the desired embossing requires this, for example in order to form a nested or point-to-point embossing.

The power transmitted to the first embossing roll 10 by means of the ink transfer roller 9 Ink 3, the rolls are transferred only to the surfaces of the projections 14 at a suitable selection of the relative arrangement 9 and 10 and a suitable choice of the materials selected. It is preferred that the recesses 16 are free of any ink 3 . Alternatively, however, it is also possible to provide ink only in the recesses 16 and to leave the projections 14 free of ink.

Now again with reference to the tissue 20 shown in detail I of FIG. 1, the tissue 20 can be seen as a multi-layer tissue. In particular, it comprises a first layer 21 and a second layer 22 . The layers run through the press nip between the first and second embossing rollers 10 , 12 , in the direction shown by the arrow in FIG. 1. The embossing rollers rotate accordingly, so that there is no relative movement on the one hand between the contacting surfaces of the first and second embossing rollers 10 , 12 and on the other hand between the surface of each roller and the tissue 20 . In particular, it is preferred that no relative movement occurs between the first layer 21 and the second layer 22 .

Passing the tissue layers 21 , 22 through the press nip between the first embossing roller 10 and the second embossing roller 12 will impart a pattern to the otherwise pattern-free tissue 20 . In addition, this provision of the tissue 20 with a pattern depending on the setting of the press nip can be effected in such a way that the first layer 21 and the second layer 22 are plastically deformed and they are pressed to such an extent that between these two layers 21 and 22 a mechanical connection is established; the press nip can also be adjusted in order to only provide the layers with a structure without a mechanical connection being established. After the tissue 20 has been passed through the press nip, it will be manageable without separating the layers 21 and 22 .

The embodiment shown in FIG. 1 and described with reference to it confers a colored pattern to only one outside of a two layer tissue 20 . However, it should be apparent to one of ordinary skill in the art from the foregoing description that in the embodiment of FIG. 1 it is also possible to impart this single-sided ink printing pattern to a tissue with more than two layers. Furthermore, it is also possible to replace the second counterpressure embossing roller 12 with an embossing roller which has a configuration similar to or different from the first embossing roller 10 . The second embossing roller 12 would then have corresponding projections and recesses. These projections and recesses could be arranged in such a way that the projections of the first embossing roller 10 touch the projections of the second embossing roller 12 . Alternatively, the projections from one embossing roll could mesh with the recesses of the second embossing roll 12 depending on the desired extent to which the embossing is to be performed.

FIG. 2 illustrates a second embodiment of the present invention. In FIG. 2, similar reference numerals are used to designate elements that correspond to those of the embodiment of FIG. 1. In particular, these are the ink reservoir 1 , the ink 3 , the ink supply chamber 5 and the ink supply chamber doctor blade 7 , which function identically to the corresponding elements of the embodiment of FIG. 1. Furthermore, the first embossing roller 10 and the second embossing roller 12 of the embodiment of FIG. 1 are also present in the embodiment of FIG. 2.

This embodiment of FIG. 2 offers a larger individual selection of the materials for the different rollers. For example, in the embodiment of FIG. 2, the ink transfer roller 9 a could typically be made of stainless steel or stainless steel, and the second ink transfer roller 9 b could be made of rubber. This is particularly advantageous if the first embossing roller 10 is also made of steel, since it improves the transfer of ink compared to the ink transfer from one steel roller to another. It is also possible to design the second ink transfer rollers with a pattern that corresponds to the embossing pattern of the pattern or patterns to be printed by the first embossing roller 10 .

Alternatively, the first ink transfer roller may be built up to a smooth, second transfer roller 9 b a pattern to present. Furthermore, alternatively or additionally, the patterns of the first ink transfer roller 9 a and / or the second ink transfer roller 9 b, which are typically formed by projections and recesses, could comprise projections of different heights. In other words, the outer surface of some protrusions could be located a distance from the central axis of the ink transfer roller that is different from the corresponding distance of adjacent protrusions. In this way it is possible to selectively wet some of the protrusions with ink in order to use these protrusions for embossing and printing and others only for embossing. In particular, it is possible to use a roller with projections on its entire surface or only a part of its surface, depending on the desired printing pattern.

In the embodiment of Fig. 1 and Fig. 2, the method by which the next adjacent roller is supplied with ink is identical. Furthermore, both embodiments serve for one-sided printing of the tissue 20 .

In both embodiments, Fig. 1 and Fig. 2, the ink 3 supplied from an ink storage tank 1 by suitable means to at least one ink transfer roller 9, 9 a, 9 b transferred. From there, the ink is transferred to a first embossing roller 10 , which in turn transfers the ink to a first surface of the tissue 20 at exactly the desired location. Because the tissue will typically have material properties that allow ink to be absorbed, precise unidirectional transfer of the ink 3 from the first embossing roller 10 to the tissue 20 can be achieved simultaneously with the embossing of two or more layers of the tissue to hold them together connect to.

It will be apparent to one skilled in the art that although the currently preferred material choice for the ink transfer roller or rollers is rubber, plastic, leather or other similarly flexible material, and which is stainless steel for the first and second embossing rollers, within the scope of the present invention for each other materials are possible. In particular, it is also possible to produce the three rollers 9 , 10 and 12 from the same material. It has been shown that ink transfer is still possible.

How the apparatus and method of the present invention can be used for two-sided printing and how the inventive product can be obtained with a double-sided pattern will now be described with reference to Figure 3.

In the embodiment of FIG. 3, two ink stores 1 , 1 containing ink 3 are provided, which are connected to ink supply chambers 5 , 5 with doctor blades 7 , 7 . The two ink reservoirs and the structure connected to them will preferably be identical. Of course, it is also possible that these elements are constructed and arranged differently, as will be apparent to a person skilled in the art. In particular, the ink in one store may have a color different from that in the other store, the amounts supplied may differ, and the ink store 1 , the ink supply chamber 5, and the ink supply chamber doctor blade 7 may be constructed accordingly.

Moreover, in the embodiment of FIG. 3 like parts are designated by the same reference numerals as in the embodiments of FIGS. 1 and FIG. 2. In the embodiment of FIG. 3, the desired positions of the tissue 20 are passed through a press nip formed between a first embossing roller 10 and a second embossing roller 12 . The direction of passage of the tissue layers is in the figure from the lower left side to the upper right side, which is also indicated by an arrow. In the following, the elements arranged to the left of the tissue 20 will be referred to as "left" and the right of the tissue 20 as the "right" elements. These labels are for convenience of description only and are not intended to limit the arrangement of these elements relative to each other.

For example, it is also conceivable for all sections to provide that the tissue 20 runs horizontally through a press nip.

Similar to those described with reference to FIGS. 1 and 2, the ink 3 is transferred from the left ink reservoir 1 through suitably selected lines to the left ink supply chamber 5 and applied to an ink transfer roller 9 c by means of an ink supply chamber squeegee 7 . From this ink transfer roller 9 c, the ink is transferred to the latter by means of line contact between this roller and the first embossing roller 10 . The ink transfer roller 10 then embosses two or more layers of the tissue 20 in cooperation with the second embossing roller 12 . At the same time, the first embossing roller 10 transfers all or part of the ink it carries on its outer surface to the tissue 20 . In a similar manner, ink 3 is transferred from the right ink reservoir 1 through a line to an ink supply chamber 5 and applied to the ink transfer roller 9 d by means of doctor blades 7 . From there it is transferred to the second embossing roller 12 and to the right side of the tissue 20 , all in a manner similar to that described with reference to FIGS. 1 and 2.

In the embodiment of FIG. 3, if desired, the printed tissue 20 obtained by the apparatus and method of the embodiment of FIG. 3 may have two complete patterns, one on each side of the tissue.

In this case, the amount of ink used in the combined embossing / printing process can be easily controlled by applying ink to the respective embossing roller so that they are below the saturation point of the tissue, which forms half or all of the thickness, to avoid. Of course, the same applies to printing on only one outer surface of tissue 20 , as described above with reference to FIGS. 1 and 2.

It will now be described with reference to FIG. 4 how the embodiments of FIGS. 1, 2 and 3 can be modified to enable multi-color printing. The embodiment of Fig. 4 will be described with reference to one-sided printing, but it will be apparent to one skilled in the art that the same arrangement can be extended to also enable two-sided printing of a tissue.

As shown with reference to FIG. 2 and described, it is b, by appropriately constructing a second ink transfer roller 9 possible only a part of all selected projections of the roll to use. The resulting print pattern on the tissue would then only be partially colored, which can result in a pleasant appearance. In FIG. 4, an additional applicator unit for the ink is shown for purposes of simplicity without the corresponding ink supply, such as an ink reservoir 1, an ink supply chamber 5 and doctor 7. In particular, this second application unit comprises two additional ink transfer rollers 9 d and 9 e. However, only one or even three ink transfer rollers can be provided depending on the type of ink and the pattern to be applied.

In the particular embodiment of Fig. 4, the ink transfer roller 9 e will be constructed in direct contact with the first embossing roller 10 according to the construction of the ink transfer roller 9 b, or the projections of the ink transfer rollers 9 b and 9 e can be of different heights. This construction can be correlated in such a way that the projections of the ink transfer roller 9 b wetted with ink touch the first embossing roller 10 at different locations than the projections of the ink transfer roller 9 e wetted with ink. In this way, a portion of the surface of the first embossing roll 10, by the ink transfer roller 9 b a first color are selectively supplied, and the remaining portions can be wetted with ink fully or partially by means of the ink transfer roller 9 e. As a result, multi-color patterns can be obtained. Alternatively or additionally, it is also possible to wet the same areas of the first embossing roller 10 with one or more ink layers, depending on how many ink transfer rollers are arranged around the circumference of the first embossing roller 10 . The ink colors can then be mixed and the tissue can be patterned with gradually changing colors.

Referring now to FIGS. 5 and 6, an alternative ink supply unit, in this case a so-called diving cylinder system, will be explained as follows.

In FIGS. 5 and 6, the desired number of layers of the tissue 20 is in turn guided by a first between an embossing roller 10 and a second embossing roller 12 formed press nip. In the embodiments of FIGS. 5 and 6, like reference numerals are used to identify elements that are similar to those shown in the embodiments of FIGS. 1 to 4.

The method of applying either a one-sided or a two-sided print pattern to tissue 20 by means of embossing rollers 10 , 12 , as is used in the embodiments of FIGS. 5 and 6, is similar to that of the previously described embodiments. In particular, one or alternatively both of the embossing rollers 10 , 12 can be provided with projections 14 and recesses 16 (detail I of FIG. 1). Furthermore, as in the previous embodiments, the single-color or multi-color printing described can also be used in the embodiments of FIGS. 5 and 6. This is particularly evident from Fig. 6 where an ink transfer roller 9 is used which is similar to that shown and described with reference numerals to the embodiment of Fig. 1.

The embodiments of Figures 5 and 6, however, use a different color delivery system. In the latter embodiments, an ink reservoir 1 'is used to hold a sufficient amount of ink 3 . The ink reservoir 1 'has dimensions large enough to enable a plunger cylinder 30 to enter the ink 3 contained in the ink reservoir 1 ' with its entire axial length. The immersion cylinder 30 is preferred, but not necessarily, to have longitudinal dimensions which correspond to those of the first embossing roller 10 .

The immersion cylinder 30 rotates in preferably constant contact with the ink 3 in the ink reservoir 1 '. Due to the material properties of the surface of the immersion cylinder 30 and the ink 3 , and the resulting friction and / or adhesion between them, the surface of the immersion cylinder 30 will entrain part of the ink 3 contained in the ink reservoir 1 ', as also shown in FIGS . 5 and 6 is shown. The entrained ink can subsequently be transferred to the ink transfer roller 9 or directly to the first embossing roller 10 and subsequently to the tissue 20 . To control the amount of ink supplied by the ink delivery mechanism of FIGS . 5 and 6, a wiper 32 is provided. The wiper 32 wipes excess ink from the immersion cylinder 30 such that only the desired amount of ink is supplied to the tissue 20 . The ink wiped by the immersion cylinder 30 will flow back into the ink reservoir 1 '.

Of course, within the scope of the present invention, it is contemplated to use color delivery systems that differ from those shown in Figures 1 through 4 and 5 through 6, respectively. For example, the ink could be applied to the first embossing roller 10 and / or the second embossing roller 12 by means of spraying, spreading, other doctor blade systems, or via other types which are suitable for applying ink or ink. Furthermore, any suitable combination of smooth and profiled rollers for adding ink or for embossing is included within the scope of the present invention. According to the invention, in each of the embodiments, the ink or color application system can be controlled to provide a precise amount of ink to be printed on the tissue so that any desired effect on the printed pattern can be achieved. Of course, the tissue and ink quality can also be taken into account in this regard.
