Definitions

  • the first and the second edge region are opposite to the embossing tool.
  • a rectangular embossing tool as is commonly used, this means that the two edge regions are each arranged on a transverse side of the rectangle.
  • the two transverse sides are here those sides of the rectangular embossing tool, which overlap or approximate after bending of the embossing tool in a cylindrical shape.
  • a corrugation is in the context of this invention, an arrangement of raised and / or recessed structures in the embossing tool, which are arranged like a grid.
  • the corrugation is a single line-shaped elevation or depression in the first edge region and a single line-shaped depression or elevation in the second edge region, which are aligned parallel to one another after the embossing tool has been tensioned on the embossing cylinder.
  • An improvement of the toothing results when two or more line-shaped elevations and / or depressions are arranged in the respective edge region, which are aligned parallel to each other after the clamping of the embossing tool on the embossing cylinder.
  • the bending or buckling in the edge region of the embossing tool allows corrugation on both sides of the embossing tool, wherein the two corrugations interlock with each other. This results in a firmer recording of the embossing tool on the embossing cylinder, whereby slippage or displacement of the embossing tool is reduced or prevented on the embossing cylinder. Furthermore, by the corrugation a register-accurate alignment of the embossing tool on the embossing cylinder in the form of a "snapping" both corrugations into each other in a predetermined position allows.
  • the corresponding corrugation no longer be located in the edge region directly on an edge of the embossing tool, as they would otherwise be arranged inside the spiral bends or bends.
  • the corrugation must be moved parallel to the edge of the embossing tool to the center of the embossing tool and to such an extent that it comes to rest on the bottom of the new edge of the embossing tool after multiple bending or buckling.
  • the height of the structures of the corrugation with respect to the surrounding surface of the embossing tool at least 10 microns, preferably 20 microns to 100 microns and more preferably 100 microns to 750 microns.
  • Corrugations 11 and 12 in the form of parallel line-shaped elevations are arranged on the left and the right edge of the embossing tool 1 and aligned parallel to the outer edge of the edge regions of the embossing tool 1.
  • the corrugation 11 is bent or bent along the edge 17 in the direction of the arrow by about 180 ° to the rear on the back of the embossing tool 1. After a circular arc bending of the embossing tool 1 accordingly Fig. 4 intermesh the two corrugations 11 and 12 into each other, thereby preventing a displacement of the embossing tool 1in the x direction.
