Definitions

  • the present invention relates to a device for fine embossing of packaging material with at least two embossing rollers, according to the preamble of patent claim 1.

  • so-called inner liners which are wrapped around a number of cigarettes, or can act as packaging material for chocolate, butter or similar foods, electronic components, jewelry or watches.
  • the so-called inner liners initially consisted of pure aluminum foils, such as household foils, and these were characterized by the fact that they were carried out between two rolls, of which at least one roller had a relief, the so-called logos.
  • a pair of rollers consisted in the majority of a steel roller on which a relief was formed and a counter-roller of a resilient material, such as rubber, paper or Plexiglas.
  • the relief of the patrone roller was transferred to a layer on the stencil roll and the recesses corresponding to the raised areas were etched out or otherwise worked out. Recently, lasers have been used for this engraving.
  • Tactile generated information can be read, for example, by means of laser beams through the surface-dependent reflectivity. There are also developments today that aim to create acoustically audible effects by painting the surface.
  • WO 2013156256 A1 of the same applicant is to solve the general problem to provide a method for producing a set of embossing rollers with which it is possible to carry out embossing for a variety of described surface structures of the specified materials of various kinds in the online operation of a packaging plant, proposed that in one Pater-Mater embossing roll system, the template surface structure is made independent of a previously generated or physically existing male surface structure.
  • an embossing device with an embossing roller set with at least one cooperating Patrizen- and die rollers, which not only allows fine embossing for a variety of described surface structures of the specified materials of various kinds On-line operation of a packaging plant, but also the high-quality, eye-catching fine embossing of sophisticated logos, such.
  • fine embossing with the pater-matter system is understood to mean that the contours of the fine embossing structures of the rolls have a linear total error in the axial and radial directions of less than +/- 10 ⁇ m and / or an angle error of less than 5 °.
  • FIG. 1 shows schematically and simplifies a structure of an embossing device with a Patrizenwalze P1 and a die roller M1, wherein the die roller is driven by a drive 1.
  • the driving force from the stencil roll to the stamper roll is via a fine gear 2, 3.
  • the stamper roll has some structural elements PL1, which are raised and the stencil roll has the Patrizen structural elements associated recessed structural elements ML1.
  • the structures of the stencil roll are produced independently of the structures of the stamper roll, z. B. by means of a laser system and are therefore non-inversely congruent, giving them a better contrast. In the current state of the art, however, other manufacturing methods such as engraving, etching or milling are possible.

  • the scattering effect of the light scattering elements creates a dull appearance at these spots.
  • the resulting contrast with the environment increases the perception of the logo.
  • the exact shape or dimension of the light scattering elements is not essential for the generated light scattering within certain limits, since they are at the Limit of perception for the human eye.
