Definitions

  • such a printing roller is made of a metallic material and preferably has a chrome coating as a protection against corrosion from common printing media.
  • Such a pressure roller has become known from German patent application P 43 42 159.8.
  • a sleeve-shaped printing form is described there.
  • the sleeve whose inner diameter is smaller than the cylinder diameter of the supporting part, is mechanically expanded to the larger cylinder diameter after precentering by means of a conical chamfer piece of the pressure roller body, so that the sleeve can be pushed completely onto the roller body via an air cushion.
  • the object of the present invention is therefore to further develop a generic printing roller such that when a sleeve-shaped printing or transfer form is pushed onto the printing roller, it can be adjusted and mounted precisely and stationary on the printing roller without the principle underlying the sleeve technology being restricted becomes.
  • the single figure shows a highly schematic partial longitudinal section of a printing roller, on the roller core 1 of which a printing or transfer mold 2 is partially pushed.
  • the roller core 1 is usually designed as a hollow body which has a greater wall thickness than the sleeve-shaped printing or transfer form 2. For the most part, the roller core 1 is designed with a larger cylinder diameter than the inside diameter of the printing or transfer mold 2.
  • a cylinder piece in the form of a pre-centering cone 3 with a smaller diameter than the inside diameter of the printing cylinder 2 is provided on one end of the printing roller, by means of which the printing cylinder 2 can be roughly positioned on the printing roller.
  • the pressure cylinder 2 By pushing it further onto a conical push-on cone 4 of the pressure roller, the pressure cylinder 2 is expanded to a diameter corresponding to the diameter of the surface area 5 of the roller core 1, in which the air outlet bores 6 open.
  • the Printing cylinder 2 is elastically stretched by the emerging air and can slide on its compressed air cushion into its end position on the printing roller.
  • a thin intermediate layer 7 is provided between the surface of the roller core 1 and the inner surface of the sleeve-shaped printing cylinder 2, for the adjustment and better anchoring of the printing cylinder 2 on the printing roller.
  • the surface of the roller core 1 has an area 9 in the form of a reduction in diameter corresponding to the thickness of the thin intermediate layer 7, so that the surface areas 5 of the roller core 1, into which the air outlet bores 6 open, are higher than the area 9.
  • the stepped area 9 of the roll core 1 is covered all around with the thin intermediate layer 7, such that the surface area 5 with the air outlet bores 6 and the stepped surface area 9 of the roll core 1 with the intermediate layer covering run flat. Both end faces of such a pressure roller can be made the same.
  • the thin intermediate layer 7 is a self-adhesive plastic film that is easily exchangeable.
  • a recess 8 for guiding a cutting tool is provided between a stepped area 9 and an elevated area 5 around the roll core 1.
  • the thin intermediate layer 7 can also be formed as a coating of the complete surface, preferably of the stepped surface area 9 of the roller core 1.
  • the coating can consist of plastic, lacquer, metallic base material or ceramic materials.
  • a GfK coating is provided as the intermediate layer 7, which has a thermally insulating effect.
  • a further advantage of such a coating would be the thermal insulation of the roller core 1, which would make cooling the sleeve-shaped printing form 2 easier.
  • a thermally insulating intermediate layer 7 prevents an undesired outflow of heat from the sleeve-shaped printing form in the roller core 1. This in turn has advantages when filling gravure printing form sleeves with a thermoplastic substance, as well as in general with heat-assisted thermal transfer processes.
  • the thin intermediate layer can of course also be designed as an interchangeable sleeve.
