Definitions

  • Tissue paper existing layers for manufacturing for example a tissue hygiene product, e.g. B. kitchen towel, Toilet paper, napkins, handkerchiefs, facial tissues and the like, either using glue, or you have mechanical Tools for creating knurling or embossing used, the layers in the area of the knurled seam or Edge embossing extremely compressed and thus connected to each other were. These procedures are still common today used. Leave the tools used for this but clearly visible imprints on the tissue surfaces, the often, such as B.

These procedures are still common today used. Leave the tools used for this but clearly visible imprints on the tissue surfaces, the often, such as B.
  • the object (problem) of the invention is a method as well as to create a device that makes it easier Way is possible while largely maintaining the Softness, firmness and absorbency of the tissue paper a good one even with a larger number of layers Layer adhesion between the layers of the tissue product made with it to generate, but without negative by the consumer perceived, clearly visible prints on the outside showing tissue surfaces of the outer layers of the tissue product to leave.
  • the method and the device have the advantage that for Generation of layer adhesion on glue can be dispensed with and that the mechanical influence of the roller surface on the tissue surface is hardly or not visible. on the other hand By choosing certain boundary conditions, a visible, desired irregular pattern are generated, which for Designing new products can be used.
  • the paper receives after this layer adhesion generation a peach skin-like Surface, which makes the paper feel very soft.
  • the indentation takes place with a pressure which is sufficient for it to be Area of majority on the fiber composite of each Layers of a multi-layer tissue product Roughness peaks to inter-fiber bonds come between them touching fiber surfaces near-surface fibers neighboring outer sides of the individual layers of the tissue product.
  • Layer adhesion can also be applied in more than one nip generate and provide nips in succession, the Roller pairs can work with different pressure, e.g. B. increasing pressure. The roller pairs can also with different Pattern. If the product has more than two layers, can the layers through different pairs of rollers / nips be performed.
  • the invention also relates to the use of Abrasive paper for creating layer adhesion between layers made of tissue paper by indenting the surface structure of the Emery paper in one of at least two layers folded tissue paper in making one for the End use of certain multi-layer tissue product.
  • each such "roughness peak” sufficient height, inherent strength and Anchor strength must have to be deep enough in the paper to be able to penetrate.
  • Shape, hardness, inherent and Anchoring strength of each "roughness tip” must be such be that in the area of the fiber structure of the tissue paper end faces of the "roughness peaks” in one Press gap under load as high as possible specific Surface pressure arises, which is able to form a fiber Tissue paper that is stacked in at least two layers this surface pressure is exposed to deform so that thereby the surfaces of neighboring fibers in such intimate contact come together that selectively inter-fiber bonds occur, the sum of which leads to the arrest of the finished position Tissue product.
  • abrasive grain materials for example made of aluminum oxide, silicon carbide or Industrial diamond in a macro grain range P 40 to P 240 (DIN), for example anchored on suitable flexible Abrasive pads or directly on the surface of a massive roller made of metal or a suitable metal shell, that can be wound on a roll core.

It could too Sandblasting of the roller surface can be used. she should but with that of an emery paper of the type mentioned be comparable.
  • the pressure rollers 3 and 4 are steel rollers educated.
  • the surface structure preferably has this Steel rollers an irregularity in grain size, the grain distribution density and / or the grain shape, where pointed and there can also be angular grains.
  • the exemplary embodiment shown are both pressure rollers 3 and 4 provided with this surface structure. But it could also be sufficient, just one of the pressure rollers with this To provide surface structure and the counter roller as Train steel roller smooth or a rubber roller as To use counter roller.
  • Counter roller to use one whose surface is a Sieve structure.
  • the rubber counter roller can be used with different hardness , for example 25 to 95 Shore A.
