Definitions

  • the present invention relates to a method for producing embossing rolls for a device for embossing packaging materials with a set of two rolls, according to the preamble of claim 1 and to a set of embossing rolls produced according to the above method as well as to the use of embossing rolls in a device with two embossing rollers for embossing packaging material.

  • 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 patrix roll was transferred to a layer on the die roll and became the recesses corresponding to the raised spots etched out or otherwise worked out. Recently, lasers have been used for this engraving.
  • Tactile generated Information can be read out, 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.
  • Another object is to produce such a set of rolls industrially in the required precision and quantities. This object is achieved with the method according to Claim 10 solved. Other objects and advantages will be apparent from the dependent claims and the description below.

  • more than two embossing rollers may be arranged in such an embossing device, for. B. an embossing roller and two counter-rollers.
  • the axis 5 of the counter roller 3 is movable in the three dimensions such that a tooth of a roller can get between four teeth of the other roller, so that a slip-free self-synchronization is possible.
  • teeth of the driven roller are either completely removed or only partially, giving an image that varies with the angle of incidence and viewing angle of the viewer.
  • mount on or on the teeth by means of micro engravings authentication features or to remove or modify certain teeth in a predetermined arrangement.
  • the pin-up-pin-up rollers are excellently suited and have proven themselves over decades.
  • the requirements for precision of embossing as well as adaptations to a growing variety of packaging materials such as plastic films, hybrid films, cardboard or semi-board have increased and the more stringent regulations regarding advertising and new types of embossing which have been promised cover the limits of Pin up-pin-up embossing roll devices.
  • the device 7 according to Fig. 2 has two rollers 2 and 8, wherein the Patrizenwalze 2 may be the same as in Fig. 1 while the die roller 8 is a so-called pin down roller and the recesses 9 correspond inversely congruent to the teeth 4 on roller 2.
  • roller 2 is driven by the drive 6, while the roller 8 is driven by the teeth 4.
  • the teeth and the recesses must be worked very precisely and coordinated with each other.
  • the patrone roller 2 is manufactured and brought together with a die steel cylinder such that the teeth of the patrone roller are imaged on the die cylinder, generally with a photoresist, wax or similar layer applied to the die cylinder. Then, the recesses 9 corresponding to the teeth 4 are machined in the die cylinder, generally by etching. However, it is also known to work out the depressions of the die roller mechanically or by means of a laser system.
  • the surface structures of the rolls are required in a greater variety, as well as more rationally and, more particularly, more precisely for a substantial improvement of the embossing possibilities and quality and, above all, for use in online processes can be produced. While the accuracy of the prior art could be ensured by etching or by mechanical processing with great effort, this does not apply to the rational and thus faster production of the male-die rollers in a wide variety of surface structures.

  • Fig. 13 is the fine structure FPR and FMR around. Again, the pitch of the fine structure can be 0.07 mm.
  • Fig. 14 only the coarse structure GP1 and GM1 is shown, without fine structures.
  • Such a structure is particularly suitable for the production of tactile structures that are not only palpable but also aesthetically pleasing have attractive appearance. This can z. B. characters in braille or acoustically usable structures are generated.
