Definitions

  • the invention relates to a method for manufacturing of a relatively soft, essentially flat, but three-dimensional product and a corresponding one Product itself.
  • Such products as a whole flat products are usually considered in terms of their Volume increased by an embossing process.
  • This Volume increase can on the one hand Affect appearance and secondly the technical Characteristics. For example, if a tissue or a similar paper product is embossed, so can, in addition to an improved appearance, the Touch and button properties can be improved.
  • These touch properties can transform the Starting product by embossing the Improve the absorption properties of the product.
  • different materials come into question, e.g. B.
  • EP 0 313 766 A2 and US disclose 5,229,186 a method and an apparatus for embossing Films. It is also known from US 5,296,289 flat starting product after an embossing process Subject to stretching. The state of the art provides no suitable measures ready which the Improve the touch properties of the product.
  • This secondary has a special effect Volume increase as a superimposition of the embossing caused volume increase, since the embossing pattern of the Intermediate from a variety of each other networked joint parallelograms is formed and that stretch as optimal in about one direction runs diagonally through the parallelograms and thereby especially through diagonally opposite hinge points, which of course are not real hinge points in the mechanical sense represent, but rather from the embossing process result in lines of compacted material crossing each other and limit the parallelograms used in networking then act similarly to a pantograph if the stretching forces be applied.
  • An increase in volume is understood to mean that Embossing bulges of the whole flat starting product, so that primarily a Volume increase in the direction perpendicular to the large one Surface of the starting product takes place.
  • the expression “relatively soft” implies the need to be able to carry out an embossing process at all.
  • expression also includes a deformability of the Product in that the stretching process permanent deformation can be achieved as well as by the Embossing process.
  • the product should also be in the final state certain and possibly special flexibility and softness have, depending on the purpose and whether that Appearance or the touch characteristic is in the foreground.
  • the problem is also solved by a relatively soft, in large flat but three-dimensional product Claim 2.
  • the secondary volume increase convex and on the convex side of the primary Volume increase forming embossed pattern can be arranged. But it can also be concave.
  • the embossing pattern does not have to be, but can be symmetrical.
  • the secondary volume increase can be particularly achieve more favorably if the embossed in the embossed pattern
  • Individual shapes in plan view have a shape that between the shape of a circle and a square or Rectangle is located. However, one should there is a clear deviation from the circular shape.
  • the embossing pattern broadly forms a diamond pattern.
  • the present invention provides Claim 8 an embossing tool for producing the Intermediate product according to claim 1 ready.
  • embossing tool with its design has a significant impact on the stretch caused superimposed, permanent secondary Increase in volume.
  • the use of a is particularly expedient So-called "female" embossing tool, which has recesses in which is the material of the flat starting product for the permanent primary volume change is pressed.
  • the embossing tool has a connection between them the recesses interconnected webs on the corresponding bulges of lines pressed together by the webs and thus recessed material are limited, which lines in particularly favorable due to the "female" embossing Form parallelograms that are network-like are interconnected that this network at Applying opposite stretching forces in the direction the large area extension and essentially in Diagonal direction of the joint parallelograms of the Intermediate acts like a pantograph. Accordingly the parallelogram should be aligned in the machine direction if the stretching is in the machine direction.
  • the secondary volume expansion is particularly easy achieve effectively when the side walls in the embossing tool of the recesses starting from the tool surface run at a certain acute angle on all sides.
  • This angle should preferably be no less than about 40 ° and in particular not less than about 60 °. In this angle is particularly advantageously 65 °.
  • the number of individual shapes per square centimeter influences the formation of the secondary in a positive way Increase in volume. So this number of individual forms 0.5 to 6 and in particular 1 to 2.5 per square centimeter be.
  • the dimension of the recesses of the embossing tool has also influence the training of the permanent secondary volume increase through stretching. So it can Ratio of the depth of the recesses to the width 0.1 to 0.5 and in particular be 0.2 to 0.3.
  • the recesses in the embossing tool have staggered Side walls in such a way that starting from the Tool surface several wall sections in the depth of the Recesses are strung together and the tips Angle that the wall sections form to the tool surface, be smaller from wall section to wall section.
  • the webs between the recesses of the embossing tool can preferably have a width of 0.5 mm to 3 mm and in particular from 1.2 mm to 2.2 mm.
  • a profile can also be provided in webs, and in particular can be a number of along the same in the webs trained recesses may be provided. Form thereby bulges in the embossed lines of the product additional volume increases.
  • Figs. 1a and 1b are matching patterns shown, but so that the Fig. 1a based on the tool pattern as the embossed pattern would be viewed (reverse view) and Fig. 1b as the corresponding pattern of the embossing tool itself. Because the product is especially designed for that Intermediate product is produced by the embossing tool, is only based on the three embodiments Embossing tool described, because this also the product as such is marked.
