  • the invention relates to a rubber sleeve for a printing press. Furthermore, the invention relates to a method for producing a rubber sleeve for a printing press.
  • a rigid carrier sleeve of metal or composite material and also a semi-finished product is also provided with a blanket having at least two layers, the blanket being wrapped around the rigid carrier sleeve and secured to the rigid carrier sleeve ,
  • Such rubber sleeves therefore always have a rigid support sleeve made of metal or composite material. This results in high production costs for a rubber sleeve. Since the carrier sleeve of the known from the prior art rubber sleeves is stiff and therefore not flexible or not elastic, narrow tolerances must continue to be complied with in the prior art in order to ensure the assemblability of a rubber sleeve on a blanket cylinder of a printing press.
  • the present invention is based on the problem to provide a novel rubber sleeve and a novel method for producing the same.
  • a rubber sleeve for a printing machine is proposed with a at least two-layer structure, formed as a support layer inner layer and serving as a functional layer, the printing process serving outer layer, wherein the carrier layer and the functional layer are part of a blanket, which sleeve-like shaped to form the rubber sleeve and in the region of opposing abutting surfaces of carrier layer and functional layer is connected to each other, and wherein at least the abutting surfaces of the carrier layer are increased such that they absorb acting on the rubber sleeve circumferential forces.
  • the process for producing such a rubber sleeve is defined in claim 13.
  • a rubber sleeve for a printing machine is proposed with a at least two-layer structure, formed as a support layer inner layer and serving as a functional layer, the printing process serving outer layer, wherein the carrier layer and the functional layer are part of a blanket, which sleeve-like shaped to form the rubber sleeve and in the region of opposing abutting surfaces of carrier layer and functional layer is connected to each other, and wherein in the carrier layer, a connecting element is recessed to accommodate acting on the rubber sleeve circumferential forces.
  • the method for producing such a rubber sleeve is defined in claim 20.
  • the rubber sleeves according to the invention be it a rubber sleeve according to the first aspect of the present invention or also according to the second aspect of the present invention, no longer have a stiff carrier sleeve. This results in lower production costs. Furthermore, larger tolerances in the dimensional accuracy of the rubber sleeves are possible.
  • All layers of the rubber sleeves according to the invention are part of a blanket which serves as a semi-finished product in the production of rubber sleeves according to the invention.
  • the blanket is shaped like a sleeve and connected together in the area of its abutment surfaces. Forces acting on the rubber sleeve, namely forces acting in the circumferential direction can be absorbed by the rubber sleeve in that either the abutment surfaces of at least the carrier layer are increased according to the first aspect of the invention, or according to the second aspect of the invention, a connecting element is embedded in the carrier layer ,

  • both the abutment surfaces 13 and 14 of the carrier layer 11 and the abutment surfaces 15 and 16 of the functional layer 12 are inclined to the radial direction of the rubber sleeve 10. This results in abutment surfaces, which are formed enlarged in comparison to abutting surfaces which extend in the radial direction.
  • the abutment surfaces 13 and 14 of the carrier layer 11 and the abutment surfaces 15 and 16 of the functional layer 12 overlap in the circumferential direction. This is achieved in that the second abutting edges of carrier layer 11 and functional layer 12 are each set obliquely in the radial direction of the rubber sleeve 10. In the exemplary embodiment of FIGS. 1 and 2, the first abutting edges extend linearly over the axial width B of the rubber sleeve 10.

  • Fig. 3 shows a section of a rubber sleeve 17 according to a second embodiment of the invention.
  • the rubber sleeve 17 in turn has a two-layered construction comprising a carrier layer 18 and the functional layer 19 serving for the printing process, wherein the carrier layer 18 and functional layer 19 are in turn part of a rubber blanket used in the production of the rubber sleeve 17 as a semi-finished product.
  • abutting surfaces 20 and 21 of the carrier layer 18 and abutment surfaces 22 and 23 of the functional layer 19 are in turn connected to each other after the sleeve-like shapes of the blanket to form the rubber sleeve 17, wherein in the embodiment of FIG .. 3 only the abutment surfaces 20 and 21 of the support layer 18 are inclined to the radial direction of the rubber sleeve 17, the abutment surfaces 22 and 23 of the functional layer 19, however, extend in the radial direction of the rubber sleeve. Accordingly, in the embodiment of FIG.
  • FIG. 4 shows a further exemplary embodiment of a rubber sleeve 24 according to the invention, the rubber sleeve also having a two-layer structure comprising a carrier layer 25 and a functional layer 26 in the exemplary embodiment of FIG. 4.
  • Carrier layer 25 and functional layer 26 are again part of a rubber blanket used as a semi-finished product in the production of the rubber sleeve 24, wherein the blanket is sleeve-shaped and connected in the region of abutment surfaces 27 and 28 of the carrier layer 25 and in the region of abutment surfaces 29 and 30 of the functional layer 26.
  • at least the abutting surfaces 27 and 28 of the carrier layer 25 are increased to safely absorb acting on the rubber sleeve 24 peripheral forces and thus to ensure a secure fit of the rubber sleeve 24 on a blanket cylinder of a printing press.
  • both the abutment surfaces 27 and 28 of the carrier layer 25 and the abutment surfaces 29 and 30 of the functional layer 26 are increased by the fact that over the axial width of the rubber sleeve 24 extending, first abutting edges of the abutting surfaces are profiled in the axial direction. In the embodiment of Fig. 4, these first abutting edges are serrated or zigzag profiled. As a result, the abutment surfaces 27 to 30 of carrier layer 25 and functional layer 26 engage in one another in the sense of a toothing extending in the axial direction of the rubber sleeve 24. There are also other profiles of the first abutting edges possible, such as wave-shaped profiles.
  • FIGS. 1 to 4 have in common that the rubber sleeves 10, 17 and 24 all have at least a two-layer structure comprising a carrier layer and a functional layer, carrier layer and functional layer are part of a rubber blanket used in the production of the rubber sleeve as a semi-finished product ,
  • the rubber sleeves 10, 17 and 24 according to the invention have no rigid carrier sleeve of metal or composite material, but only on the layers of blanket from which the respective rubber sleeve is made.
  • abutment surfaces of at least the carrier layer are increased so that the carrier layer can safely absorb peripheral forces and thus ensures a secure seating of the rubber sleeve on a blanket cylinder of a printing press.
