Definitions

  • Such a pressure roller is usually made of a metallic material and preferably has a corrosion protection against common print media Chrome plating.
  • Such a pressure roller is known from German patent application P 43 42 159.8 known.
  • a sleeve-shaped printing form is described there.
  • the sleeve, whose inner diameter is smaller than the cylinder diameter of the supporting part is, after precentering by means of a conical chamfer piece of the Pressure roller body mechanically on the larger cylinder diameter widened, so that the sleeve over an air cushion completely on the roller body can be postponed.
  • the object of the present invention is therefore a to further develop the generic printing roller in such a way that Slip on a sleeve-like printing or transfer form the pressure roller adjusts it precisely and stationary on the pressure roller, or can be assembled without the base of the sleeve technology principle is limited.
  • the single figure shows a partial schematic Longitudinal section of a pressure roller, on the roller core 1 partially one Printing or transfer form 2 is postponed.
  • the roller core 1 is usually designed as a hollow body in comparison to the sleeve-shaped printing or transfer form 2 a larger one Has wall thickness. For the most part, the roll core 1 with one larger cylinder diameter than the inner diameter of the Printing or transmission form 2.
  • a cylinder piece in shape on one end of the pressure roller a pre-centering cone 3 with a smaller diameter than that Inside diameter of the printing cylinder 2 is provided, by means of this Printing cylinder 2 can be roughly positioned on the printing roller.
  • the printing cylinder 2 By pushing it further onto a conical one Sliding cone 4 of the printing roller, the printing cylinder 2 is on a Diameter corresponding to the diameter of the surface area 5 of the roll core 1, in which the air outlet holes 6 open, expanded.
  • the Printing cylinder 2 stretched elastically by the escaping air and can be in its final position on the on a compressed air cushion Slide the print roller.
  • a thin intermediate layer 7 for adjustment and better anchoring of the pressure cylinder 2 on the Print roller provided.
  • the surface of the roll core 1 has a corresponding Thickness of the thin intermediate layer 7 of the offset region 9 in shape a reduction in diameter so that the surface areas 5 of the roll core 1, into which the air outlet holes 6 open, lie higher than the offset area 9.
  • the stepped area 9 of the roll core 1 is all around with the thin one Intermediate layer 7 is coated, in such a way that the surface area 5 also the air outlet holes 6 and the stepped surface area 9 of the roll core 1 with the interlayer covering run flat. Both end faces of such a pressure roller can be the same be executed.
  • the thin intermediate layer 7 is one self-adhesive plastic film that is easy to replace. To the exact cutting of the film on the roll core 1 is between one offset area 9 and an elevated area 5 each A groove 8 runs around the roll core 1 for guidance a cutting tool provided.
  • the thin intermediate layer 7 can also be used as Coating of the entire surface, preferably the stepped one Surface area 9 of the roll core 1 may be formed.
  • the Coating can be made of plastic, paint, metallic base material or consist of ceramic materials.
  • a GfK coating is used as the intermediate layer 7 provided that acts thermally insulating.
  • Another advantage such a coating would be the thermal insulation of the Roll core 1, whereby cooling of the sleeve-shaped printing form 2nd would be relieved.
  • a thermally insulating intermediate layer 7 prevents an undesirable outflow of heat from the sleeve-shaped Printing form in the roll core 1. This in turn has advantages in Filling of gravure form sleeves with a thermoplastic Substance, as well as in general in the case of heat-assisted Thermal transfer process.
  • the thin intermediate layer can of course also be used as replaceable sleeve be formed.
