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 rubber sleeve After a second well-known in practice for the production of a rubber sleeve is also a rigid, circumferentially closed or continuous support sleeve made of metal or composite material and further provided as a semi-finished product a blanket with a least two-layer structure, wherein the blanket wrapped around the rigid support sleeve and firmly connected to the rigid carrier sleeve.
  • EP 0 571 909 a rubber sleeve with a carrier sleeve and a cover layer or a rubber blanket, wherein the seam of the support sleeve and the seam of the blanket are positioned one above the other to achieve an optimally utilized print length.
  • pamphlet DE 101 33 726 also describes a rubber sleeve with a carrier sleeve and a cover layer, wherein the ends of the carrier sleeve layer, which form the seam, are fastened together.
  • pamphlet EP 1 705 030 discloses a further rubber sleeve in which abutting surfaces of a base layer serving as a carrier sleeve are connected to one another, and abutting surfaces of a functional layer serving as a blanket are connected to one another.
  • the present invention is based on the problem to provide a novel rubber sleeve and a novel method for producing the same. This problem is solved by a rubber sleeve according to claim 1.
  • the rubber sleeve according to the invention has an at least two-layered construction with an inner layer formed as a base layer and an outer layer serving as a functional layer, wherein the base layer and the functional layer are produced by cylinder-like molding of a separate, flat blank, and abutting edges of the base layer and the functional layer is not congruent but offset from each other.
  • the rubber sleeve according to the invention is completely without rigid, closed in the circumferential direction or in the circumferential direction continuous carrier sleeve. Rather, the rubber sleeve according to the invention is formed by cylinder-like molding of at least two flat blanks, wherein a first planar blank forms the base layer and a second planar blank forms the functional layer of the rubber sleeve according to the invention.
  • the flat blanks for the base layer as well as the functional layer can be obtained from sheet goods, which can be produced extremely economically in a continuous process.
  • the rubber sleeves of the invention are in a simple manner and therefore inexpensive to produce.
  • Fig. 1 shows a schematic representation of a rubber sleeve 10 according to the invention for a printing press, wherein the rubber sleeve 10 has an at least two-layer construction of an inner layer or base layer 11 and an outer layer or functional layer 12 serving the printing process.
  • the functional layer serves to transfer printing ink to a printed product.
  • the base layer 11 and the functional layer 12 of the rubber sleeve 10 according to the invention are produced by cylinder-like or tubular-like forms each of a separate, flat blank, wherein formed during molding of the flat blanks abutting edges 13 of the base layer 11 and abutting edges 14 of the functional layer 12 is not congruent but rather, they are offset from each other.
  • the abutting edges 13, 14 of the base layer 11 and functional layer 12 are each axially parallel to a longitudinal center axis of the rubber sleeve 10, the abutting edges 14 of the functional layer 12 being offset from the abutting edges 13 of the base layer 11 by an angle of approximately 180 °, in such a way that they are approximately diametrically opposed to the rubber sleeve 10.
  • the abutting edges 13 and 14 of the base layer 11 and functional layer 12 can of course also be offset by a different angle to each other, said angle preferably between 10 ° and 350 °, in particular between 40 ° and 320 °, preferably between 90 ° and 270 °. Particularly preferred is the in Fig. 1 shown variant in which the abutting edges 13, 14 of base layer 11 and functional layer 12 are offset by approximately 180 ° to each other.
  • the base layer 11 and the functional layer 12 of the rubber sleeve 10 according to the invention are produced by cylinder-like molding of a separate, flat blank in each case.
  • the planar blanks are preferably shaped such that the abutting edges 13 of the base layer 11 as well as the abutting edges 14 of the functional layer 12 abut gap-free. In this case, the abutting edges 13 of the base layer 11 as well as the abutting edges 14 of the functional layer 12 are not connected to each other. Base layer 11 and functional layer 12 of the rubber sleeve 10 are thus not closed in the circumferential direction or not continuous in the circumferential direction.
  • a gap is formed between the abutting edges of the base layer and / or between the abutting edges of the functional layer, wherein the respective gap preferably with a material, for. B. is filled with a sealing material. Due to the sealing material, however, the abutting edges 13 of the base layer 11 as well as the abutting edges 14 of the functional layer 12 are not frictionally connected. Also in this case, the base layer 11 and functional layer 12 of the rubber sleeve 10 are not closed in the circumferential direction or not continuous in the circumferential direction.
  • the base layer 11 and the functional layer 12 of the rubber sleeve 10 according to the invention are connected to one another, preferably by gluing, by welding or by vulcanization.
  • the base layer 11 and the functional layer 12 can also be connected to each other by any other joining method. Then, when the functional layer 12 is bonded to the base layer 11, is positioned between a radially outer surface of the base layer and a radially inner surface of the functional layer of a bonding layer, namely a layer of adhesive.
  • the blank for the base layer 11 is preferably formed from a plastic, a fiber composite material or a metal.
  • the blank for the functional layer 12 is preferably formed from a blanket.
  • the procedure is such that first a flat blank for the base layer 11 of the rubber sleeve 10 is provided, wherein the flat blank for the base layer 11 is shaped like a cylinder in a second step of the method according to the invention, but without the abutting edges 13 of FIG Base layer 11 to connect with each other.
  • the cylinder-like shaping of the flat blank for the base layer 11 takes place on a production cylinder.
  • the cylinder-like, planar blank for the base layer is preferably held by negative pressure on the production cylinder.
  • a planar blank for the functional layer 12 of the rubber sleeve 10 according to the invention is provided, wherein subsequently the planar blank for the functional layer is formed in a cylinder-like manner around the cylinder-like shaped base layer 11 held on the production cylinder without again abutting edges 14 Function layer 12 to connect with each other.
  • the cylinder-like shaping of the blank for the functional layer 12 around the already cylinder-like shaped blank of the base layer 11 takes place such that the abutting edges 13 of the base layer 11 and the abutting edges 14 of the functional layer 12 are not congruent but rather offset from each other.
  • an adhesive is preferably applied to a radially outer surface of the base layer 11 in order to form the cylinder-like shape of the planar blank of the functional layer 12 with the already cylinder-like base layer 11 connect to.
  • the two layers 11 and 12 stabilize each other without having to connect the abutting edges of base layer 11 and functional layer 12.
  • shock areas or gaps with a material such.
  • a material such as a sealing material, filled, but without establishing a positive connection between the abutting edges.
  • a sealing material is preferably compressible.
