Definitions

  • 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.
  • a rubber sleeve with the features of the preamble of claim 1 is known from US 2004/144276 A1 known.
  • the present invention is based on the problem to provide a novel rubber sleeve and a novel method for producing the same.
  • the rubber sleeve according to the invention no longer has 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 ,
  • Fig. 1 and 2 show a rubber sleeve 10 according to the invention for a printing machine, wherein the in Fig. 1 and 2 Rubber sleeve 10 shown has a two-layer structure.
  • the rubber sleeve 10 has an inner layer formed as a carrier layer 11 and a functional layer 12 formed as an outer layer serving for the printing process.
  • the layers of the rubber sleeve 10, in the embodiment shown the carrier layer 11 and functional layer 12, are all part of a blanket, which serves as a semi-finished product for the production of the rubber sleeve 10 according to the invention.
  • the rubber blanket comprising the carrier layer 11 and the functional layer 12 is sleeve-shaped for the production of the rubber sleeve 10 according to the invention and connected to one another in the region of opposing abutting surfaces.
  • the connection takes place both in the region of opposing abutment surfaces 13 and 14 of the carrier layer 11 and in the region of opposing abutment surfaces 15 and 16 of the functional layer 12.
  • the abutment surfaces 13 and 14 of the carrier layer 11 and the abutment surfaces 15 and 16 of the functional layer 12 are bounded by abutting edges, namely first abutting edges extending across the axial width B of the rubber sleeve 10 and second abutting edges extending across the radial thickness D of the rubber sleeve 10 extend.
  • 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.
  • Fig. 2 can be removed, overlap the abutting surfaces 13 and 14 of the carrier layer 11 and the abutment surfaces 15 and 16 of the functional layer 12 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 embodiment of Fig. 1 and 2 the first abutting edges extend linearly over the axial width B of the rubber sleeve 10.
  • the rubber sleeve according to the invention is formed exclusively by the layers of rubber blanket, which is used in the production of rubber sleeve 10 according to the invention as a semi-finished product.
  • the carrier layer 11 of the rubber sleeve 10 according to the invention is designed as a flexible or elastic carrier layer made of a plastic which is fiber-reinforced by means of plastic fibers.
  • the outer functional layer 12 serves for the printing process. In the functional layer 12 more layers, such. As a compressible layer, a register layer and a cover layer be positioned, the abutting surfaces are formed as the abutting surfaces of the support layer and / or functional layer.
  • 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 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 Another embodiment of a rubber sleeve 24 according to the invention shows Fig. 4 , wherein also in the embodiment of Fig. 4 the rubber sleeve has a two-layered construction of a carrier layer 25 and a functional layer 26.
  • Carrier layer 25 and functional layer 26 are in turn part of a blanket used in the production of rubber sleeve 24 as a semi-finished product, wherein the blanket sleeve-shaped and in the region of abutting surfaces 27 and 28 of the carrier layer 25 and in the region of abutting surfaces 29 and 30 of the functional layer 26 is connected. Also in the embodiment of Fig.
  • At least the abutting surfaces 27 and 28 of the carrier layer 25 are increased in order to safely absorb peripheral forces acting on the rubber sleeve 24 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 the first abutting edges of the abutment surfaces extending over the axial width of the rubber sleeve 24 are profiled in the axial direction.
  • These first edges are jagged or zigzag profiled.
  • 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.
  • the rubber sleeves 10, 17 and 24 all have at least a two-layer structure comprising a carrier layer and a functional layer, wherein the carrier layer and functional layer are part of a rubber blank 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.
  • Fig. 1 to 4 are abutment surfaces of at least the carrier layer increased, so that the carrier layer can safely absorb peripheral forces and thus ensures a secure fit of the rubber sleeve on a blanket cylinder of a printing press.
  • the carrier layers 11, 18 and 25 of the rubber sleeves 10, 17 and 24 are all formed as flexible or elastic, fiber-reinforced plastic layers. Between the carrier layers 11, 18 and 25 and the functional layers 12, 19 and 26 of the rubber sleeves 10, 17 and 24, further layers may be positioned, such. B. a register layer.
  • the procedure is that a blanket with the appropriate number and nature of the layers of the later kausleeves is provided.
  • the blanket provided has a construction of at least two layers consisting of a carrier layer and a functional layer.
  • the blanket provided is machined in the area of side surfaces serving as abutting surfaces, in such a way that at least the abutting surfaces of the carrier layer of the blanket are enlarged.
  • the blanket is shaped like a sleeve and connected to each other in the area of the adjoining abutment surfaces. The bonding takes place by gluing, welding or vulcanization.
