  • GPP glass fiber reinforced sleeve
  • This The thickness of the sleeves is such that they can be pushed onto the Transfer cylinder, which is usually used for indirect printing processes working printing machines is called rubber cylinders, by air slightly can be expanded. This is advantageous because, like that, in particular U.S. Patent 5,429,048 shows such a sleeve through the side wall of a Printing machine on the previously uncovered transfer cylinder can be postponed.
  • Transfer cylinder provided openings with the sleeve to be pushed on Compressed air expanded so that application is possible in a simple manner after which the compressed air is removed and the sleeve is firmly seated occupies on the transfer cylinder.
  • At least one is on this inner, preferably metallic support sleeve another layer - directly or indirectly - applied, which is compressible, d. i.e., the Has air pockets.
  • At least one top layer is over this layer provided, which can for example consist of an elastomeric material.
  • a forme cylinder or a printing form for example an offset printing plate or a sleeve-shaped offset printing form, the image to be printed is transferred and transferred to a print carrier.
  • the compressible layer e.g. an elastomer with Air pockets
  • another non-stretchable layer provided, for example in the form of a hard elastomeric material or for example in the form of short fibers (e.g. threads) that are also in the hard elastomeric material can be embedded.

  • a cover layer 6 is provided on the non-stretchable layer 5, For example, from an elastic material with the offset printing process can be printed.
  • a metal sleeve is preferably used as the carrier sleeve 3 used, for example made of steel, which is expandable by air and the one Has joint 7.
  • This joint 7 can for example be a weld be formed in an advantageous manner in that the metallic sleeve is made of a plate whose ends are welded together so that the joint 7 results.
  • the carrier sleeve 3 can also be designed to be shock-free and gap-free, in which case then the joint 7 shown in FIG. 1 is omitted. With a metallic Such execution recommends the production by galvanic means. Non-metallic carrier sleeves 3 are advantageously free of bumps and gaps producible.
  • a joint is understood in particular to mean that a sleeve or cylindrical rubber or plastic layer or a sleeve or cylindrical metallic or non-metallic carrier in the circumferential direction is not endless, i.e. not seamless or not continuous, i.e. that in longitudinal or Axis direction there is a seam or a joint.
  • the joint can have abutting layers. It can also be a gap between represent the ends of a layer, which is advantageous with an adhesive or vulcanizable material is closed.
  • the compressible layer 4 also has a joint 8 which can be produced in that the compressible layer on the metal sleeve 3 4 is glued in the form of a rubber blanket, so that the joint 8 through the Ends of the rubber layer 4 are formed.
  • a non-stretchable layer 5 on the compressible layer 4 these also have a joint 9 according to the invention, which can be formed in the manner described above.
  • such Layer structure d. H. a carrier sleeve 3 preferably made of metal with a Butt joint 7 and at least one compressible layer 4 applied a joint 8, a cover layer 6 applied without a joint.
  • cover layer 6 - just like the compressible layer 4 - Has air pockets, so that the cover layer 6 has a certain Compressibility has what is advantageous compared to the prior art and too lead to better printing results or printing behavior and better web guidance can.
  • the sleeve according to the invention can also be particularly advantageous in this way be made that a welded metal sleeve 3 made of steel or aluminum or, for example, a CFRP sleeve with a joint is used on the a conventional offset rubber blanket, e.g. B. with a compressible layer, is applied, for example glued or vulcanized or is. After that the top layer of the conventional rubber blanket is removed, for example, sanded and replaced by a continuous, d. H. a shock-free cover layer 6 applied, for example vulcanized.
  • Across from the known sleeves is such a manufacture and such Sleeve construction much cheaper and has a number of advantages.
  • the joints 8, 9 are one above the other because they are the ends of the conventional blanket, which was glued to the carrier sleeve 3, represent.
  • the joints 8, 9 can advantageously - but do not necessarily have to be direct be arranged above the joint 7.
  • the individual joints 7, 8, 9 can also be seen circumferentially at others Digits are d. H. they do not have to be on top of one another, as shown.
  • the advantageous arrangement of short is not stretchable pieces, such as threads.
  • the sleeve 2 according to the invention offers a variety of possible uses not just on the use of offset web-fed rotary presses are limited.
  • this sleeve 2 can also be used with others indirect printing processes, such as indirect gravure, are used or as Roller are used.
