Definitions

  • the invention relates to a carrier sleeve for printing and transfer forms made of a metallic material, the starting form of which is a rectangular, thin-walled plate piece which is bent into the desired hollow cylindrical shape and the mutually facing edges of the plate piece are firmly connected to one another.
  • German patent application P 41 40 768 a sleeve-shaped offset printing form has become known, which is manufactured from a rectangularly cut metal plate by connecting the mutually facing edges of the plate by means of a weld seam.
  • the carrier sleeve produced in this way is coated and exposed all around except for the weld seam.
  • DE 42 17 793 C1 discloses a sleeve-shaped offset rubber blanket which is also made from a cut carrier plate, to which a rubber layer is applied in the flat state, by welding the beginning and end of the carrier plate together with the rubber layer.
  • a support sleeve for printing and transfer forms made of a metallic material the starting form of which is a rectangular, thin-walled plate piece which is bent into the desired hollow cylindrical shape and the mutually facing edges of the plate piece are firmly connected to one another, in which the sleeve surface forms a homogeneous surface is processed, so that continuous printing can be carried out, an advantageous alternative to the nickel, GRP and CFRP sleeves was found from both an ecological and economic point of view, which is also universally applicable for various printing processes.
  • the manufacturing costs of a welded precision sleeve machined according to the invention are many times lower than the manufacturing costs of galvanic nickel sleeves or even wound GfK or CfK carrier sleeves, especially since it is becoming increasingly difficult to produce nickel sleeves galvanically, since this manufacturing process entails great environmental pollution.
  • the carrier sleeves according to the invention can be made of aluminum, steel, stainless steel, copper or brass, depending on the particular application.
  • Fig. 1 shows a highly schematic embodiment of a carrier sleeve 1 made of a metallic material, which can be aluminum, steel, stainless steel or brass.
  • the initial shape is a rectangular, thin-walled plate piece that has been bent into the desired hollow cylindrical shape.
  • the mutually facing edges of the plate piece are preferably firmly connected to one another by means of a weld seam 2.
  • Fig. 2 shows the possibility of producing the carrier sleeve 1 quasi continuously, as is done today for pipe welding.
  • the welding process itself is carried out using a laser beam.
  • the precision sheets made of aluminum, steel, stainless steel, copper or brass preferably have a wall thickness s of 0.1 to 0.6 mm.
  • the carrier sleeves can also be manufactured with the welding device known from DE 43 11 078.
  • the outer surface of the whitened carrier sleeve 1 is processed so that a homogeneous, continuous outer surface is obtained.
  • Known manufacturing processes such as turning, grinding or the like, which make a metal surface smooth, can be used for surface processing.
  • the original wall thickness of the thin-walled plate piece must be chosen so that the material removal from the outer surface of the welded carrier sleeve is taken into account.
  • a particularly advantageous embodiment of the weld seam is to provide a seam elevation 3 on the outer surface of the sleeve 1 and to process it in a subsequent process step in such a way that a continuous, endless jacket surface is formed on the carrier sleeve surface without material removal from the precision sheet is necessary, or this material removal is at least less.
  • the seam increase 3 is by welding filler materials such. B. wire or powder, or by targeted protective gas guides, or achieved by build-up welding following the actual welding process.
  • the entire sleeve surface including the connecting seam, in the present case a weld seam 2 is chemically roughened, anodized and provided with a final photosensitive layer, as is already known from the process steps in the production of printing plates.
  • this printing form sleeve is identical to the usual printing plates, except that continuous printing is possible with this printing form sleeve.
  • Aluminum sheets are preferably used for this.
  • a water-bearing layer to an aluminum sleeve or another metallic sleeve if the sleeve material itself is not water-bearing, but should be made water-bearing.
  • ceramic materials can be applied as water-bearing layers by means of thermal spray processes.
  • this welded precision sleeve 1 which is also surface-treated as described above, can be used directly as a carrier for a flexible printing form, rubber stereo or engraved rubber printing form and thus replaces the known nickel, GfK and CfK sleeves.
  • a welded carrier sleeve 1 which is surface-treated as described above, is galvanized or sprayed all around, a metallic layer, preferably a copper alloy, which in turn is engraved in a subsequent step.
  • Plastic layers can also be applied, which are then also engraved.
  • the entire surface-treated sleeve surface, including the connecting seam 2 is covered with an endless rubber layer structure, so that from a printing point of view, these blanket sleeves are identical to the usual blankets, but with these blanket sleeves, continuous printing is possible.
  • the type of rubber layer depends on the respective printing process and regardless of the material of the carrier sleeves.
