Definitions

  • the invention relates to a printing roller, in particular an intaglio roller with, a cylinder core and an associated tube as a support for an image to be printed or the like.
  • the object of the present invention is to provide a pressure roller of the type mentioned in the introduction, in which at least the galvanizing process is avoided.
  • the tube consists of mechanically engravable material with a hardness between 95 HV and 200 HV.
  • this printing roller according to the invention it is only necessary to engrave the image to be printed or the like, so that an elaborate electroplating bath u. The like. are not necessary, since a surface free of copper layers is present.
  • the tube consists of a material with a hardness of approximately 170 HV, preferably made of brass with the trade name RMS 60 PB CuZN 38 PB 1. It has been found in tests that material with this hardness or made of brass can be engraved very well, especially with a diamond. At the same time, a long service life is achieved with this material or this degree of hardness, since this largely avoids material displacement during printing.
  • the cylinder core and the tube are expediently connected to one another by hot drawing and / or by means of adhesive. This results in a stable connection in a simple manner.
  • the invention also relates to a method for producing an intaglio printing roller and according to the invention is particularly characterized in that the engraving is carried out by a particularly electronically controlled engraving device with a diamond stylus in a variable screen process.
  • a particularly electronically controlled engraving device with a diamond stylus in a variable screen process.
  • a rotogravure roller 1 (FIG. 1) has a cylinder core 2 and a tube 3 applied thereon.
  • the connection between the cylinder core 2 and the tube 3 can be made, for example, by hot drawing. In this case, it is expedient to design the tube 3 comparatively thin-walled.
  • the tube 3 is preferably made of brass which can be engraved by machine, its hardness preferably being 170 HV. With this hardness, problem-free engraving is still possible on the one hand, and on the other hand, with this hardness, the gravure roller also has a long service life.
  • an engraving device 4 is provided which has a diamond stylus 5.
  • the engraving device 4 has an electronic control, by means of which even more complicated engraving patterns can be carried out.
  • the engraving device could also have a memory for different engraving patterns, so that a changeover can be carried out very easily. It is preferred to engrave with the engraving device, the screen fineness being able to be varied depending on the requirements.
  • Fig. 2 shows a slightly modified rotogravure roller 1 a, in which the cylinder core 2 is variable in its outer diameter, so that a loosening or fixing one located thereon in a simple manner Tube 3 a is possible.
  • the outer tube 3 a has a higher dimensional stability, which can be achieved for example by a slightly larger thickness.
  • FIG. 2 shows the cylinder core in its smallest diameter state for clarification, this being shown somewhat more strongly here.
