- the respective layer webs are embossed, one of the layer webs provided with glue and then passed to form a so-called "nested" structure through a gap arranged between the two embossing rollers of the roller pairs and the layers are firmly connected to each other via a subsequent connecting roller.
- tissue and / or tissue-like materials such as toilet paper, handkerchiefs, kitchen towels or the like, which carry decorative patterns.
- the respective decorative patterns appear very concise and sharp, and optionally the surface product is additionally added by means of color an optical effect.
- tissue is understood to mean a product which corresponds to DIN 6730. Accordingly, tissue is a product which consists wholly or predominantly of pulp fibers, with a fine and soft crepe, which is creped in a closed formation in the paper machine with a dry content of more than 90%, consists of one or more layers, is particularly absorbent, a surface mass of the individual layer of less than 5 g / m 2 before creping and a creping wet stretch greater than 5%.
- tissue-like material is understood as meaning a material which, in contrast to tissue material, is produced by changes in the drying process.
- tissue-like material is a product predominantly made of cellulose fibers with large and wide creping and open formation, which is creped dry in the paper machine and from one or more layers wherein the basis weight of a layer before crimping is less than 25 g / m 2 and the wet crumb elongation of a layer after crimping is greater than 24%.
- the material can also be made from waste paper.
- an embossing device for at least two-ply surface products such as toilet paper, handkerchiefs and the like

- the embossing device according to the invention can also have two or even three gluing units and can be used for the production of at least two-ply, preferably at least three-ply, but also four- or five-day surface products.
- the individual layers are thereby unrolled as webs of unwinding devices, in which case the webs can also be configured as double-layered or even three-layered in advance.
- embossing device Due to the embossing device according to the invention is advantageously achieved that due to the intended number of embossing points (also called embossing nubs) on the embossing roller of the first pair of rollers sufficient bulk and softness of the relevant web is given, i. that this has a higher volume than the embossed by means of the second pair of rollers at least one further layer web. This is provided by means of the embossing roller of the second pair of rollers with a decorative pattern. Due to the higher density of the embossing points here a very clear representation of the decor pattern is achieved.
- the embossing points of the embossing roller which mediates the decoration of the further layer web can be arranged linearly and at right angles to each other.
- the respective rows formed by the embossing points are preferably formed symmetrically offset from one another.
- the decor pattern is caused in the embossing roll by simply omitting the embossing points at the appropriate places.
- the embossing points are not arranged linearly, but arranged in the form of the pattern itself on the embossing roller.
- a flower motif surrounds a closed certain number of embossing points in the form of just a flower, whereby the embossed motif in the finished surface product for the viewer is clearer and clearer.
- the softness of the product is also increased.
- the decor pattern itself can have any configuration, it can be designed, for example, in the form of a flower, a bird, a heart, etc.
- the embossing device is configured such that the layer which carries the decorative pattern comes to lie on an outer side of the formed finished surface product, wherein it is further preferred that the side of the web which bears directly on the embossing roller of the second pair of rollers, an outer side of the surface product forms.
- the gluing unit applies color-added and / or colored glue.

- the first regions 26 are arranged between the individual regions 28 and merge into one another, the second regions 28 are not connected to one another.
- the individual embossing points of the first regions 26 are arranged as uniformly as possible on the surface of the embossing roller 20 in order to obtain a relatively uniform overall appearance, in particular when applying a colored glue.
- the diameter of the embossing surface of the embossing points is slightly higher than in the embodiment according to FIG. 2, namely at 0.5 mm.
- Fig. 6 now shows an alternative embodiment of the surface of the embossing roll 20, which has a plurality of embossing nubs.
- This is an alternative embodiment to the surface shown in FIG. 5.
- two or three embossing tuft rows 50 or inside the second regions 28 a embossing tuft row 50 are arranged, which have a higher height than the embossing tubs in the first regions 26.
- the height of the embossing nubs in the first regions 26 is 0.8 mm
- the height of the embossing nubs in the rows 50 is 1, 2 mm.
- the different height of the embossing nubs surrounding the second regions 28 is illustrated by the different contrast of the embossing nubs of the first regions 26 and those of the second regions 28. If, for example, a colored glue is only applied to the rows 50, a product is obtained which produces a has lower stiffness, and at the same time a nice visual effect is obtained. As can be seen from FIG. 6, when relatively complex patterns are formed, it is also possible for the embossing nubs located within a pattern to be raised, as well as the rows 50 surrounding the pattern, in order to produce an optical glue, in particular when a colored glue is applied To achieve effects.
- FIG. 7 shows a further alternative embodiment of the surface of the embossing roller 20 with a central axis 21 which has a plurality of embossing nubs.
- the second regions 28 in the interior embossing tuft rows 50 which, as in Fig. 6 as well as the at least immediately adjacent to the second regions 28 embossing tuft series of the first regions 26 may have a higher height than the embossing tufts in the first regions 26, so that Applying colored glue a beautiful visual effect can be achieved.
- the first regions 26 have an uneven distribution of the embossing nubs over the surface of the embossing roller 20, wherein their density is increased in the environment 54 of the second regions 28.
- the first regions 26 have a more even distribution of the embossing nubs.
- embossing device By means of the embossing device according to the invention, it is advantageously possible to easily and simply entail a high quality embossed pattern, which is preferably made of a tissue and / or tissue-like material in the form of a tissue, a toilet paper, a kitchen paper and / or a household paper.
- Existing embossing devices can be retrofitted with appropriate embossing rollers with appropriate parameters. It should be noted that for the purposes of the present invention, any arrangement of the respective roller pairs to each other is possible, as well as a supply of the individual webs separated from several unwinding or already together can take place as a layer composite to the embossing device.
