Definitions

  • the invention relates to a rubber sleeve according to the preamble of claim 1.
  • Such sleeves are, for example, from US Pat. Nos. 5,429,048, 5,323 702, 5 440 981, 5 304 267 or EP-A-0 514 344.
  • a disadvantage of this known It is rubber cylinder sleeves (transfer cylinder sleeves) that the middle and lower Layers of the same must be at least partially continuous. This affects particularly disadvantageous on the manufacturing costs.
  • the object of the present invention is a generic Rubber cylinder sleeve, especially for offset web-fed rotary printing presses, in Compared to the known sleeves of this type cheaper to manufacture, at about the same or improved print quality and behavior.
  • Fig. 1 shows a partial cross section of a particular embodiment the rubber cylinder sleeve according to the invention (transfer cylinder sleeve), as they used particularly with advantages in an offset web-fed rotary printing press can be on a rubber cylinder.
  • Rubber cylinder sleeves essentially made of an inner, preferably metallic Sleeve.
  • a glass fiber reinforced sleeve GRP
  • These sleeves are in theirs Thickness so dimensioned that when it is pushed onto the transfer cylinder, the usually in printing presses working according to indirect printing processes Rubber cylinder is called, can be slightly expanded by air. This is advantageous since, as is shown in particular in US Pat. No. 5,429,048, one such sleeve through the side wall of a printing press on the previously one-sided exposed transfer cylinder can be pushed.
  • At least one is on this inner, preferably metallic support sleeve another layer - directly or indirectly - applied, which is compressible, 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. With this material is from a forme cylinder or from 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.
  • stretchable layer or non-stretchable particles, such as threads or pieces of thread be introduced directly into the volume-compressible layer mentioned above.
  • Transfer cylinder with 1 (blanket cylinder) and the openings provided on its surface or nozzles with 1a.
  • the one applied in the manner described above Transfer cylinder sleeve 2 (blanket sleeve) has, as explained above, a metal sleeve 3, preferably expandable by air, on which one compressible layer 4 is vulcanized or glued.
  • On the compressible Layer 4 is a layer of a non-stretchable material 5, preferably one hard elastomer layer with short fibers, which are not specified, intended.
  • 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, which is advantageously formed in that the metallic sleeve a plate is made, the ends of which are welded together so that the Joint 7 results.
  • a sleeve or cylindrical Rubber or plastic layer or a sleeve or cylindrical metallic Beams are not endless in the longitudinal or axial direction, i.e. not seamless or not is continuous.
  • the compressible layer 4 also has a joint 8 which can be produced in that the compressible layer 4 on the metal sleeve 3 is glued in the form of a rubber blanket so that the joint 8 through the ends 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 a layer structure i.e. a carrier sleeve 3 preferably made of metal with a joint 7 and at least an applied compressible layer 4 with a joint 8, a Cover layer 6 applied without a joint.
  • cover layer 6 - 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 is used with a joint on which a conventional offset rubber blanket, e.g. B. with a compressible layer, applied, for example glued. After that the top layer of the conventional rubber blanket is removed, for example sanded and in their place a continuous, i.e. a bumpless Cover layer 6 applied, for example vulcanized.
  • a conventional offset rubber blanket e.g. B. with a compressible layer
  • a continuous, i.e. a bumpless Cover layer 6 applied, for example vulcanized.
  • a sleeve structure much cheaper and has a number of advantages. In this case are the joints 8, 9 one above the other, since they are the ends of the conventional Rubber blanket, which was glued to the carrier sleeve 3, represent.
  • the butt joints 8, 9 can advantageously - but not necessarily - be arranged directly above the joint 7.
  • the individual joints 7, 8, 9 can also be seen circumferentially at others Digits, i.e. 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 according to the invention offers a variety of uses, which are not are only limited to the use of offset web-fed rotary presses.
  • this sleeve can also be used for other indirect printing processes, such as indirect gravure, are used or used as a roller.
  • a particular advantage is that a circumferential registration, that is, an application the sleeve on the cylinder in a predetermined circumferential position is not required and that nevertheless all essential advantages can be achieved in the production, which are typical for finite transfer media (rubber blankets or sleeves).
  • layer 3 from fiber-reinforced hard rubber - with or without seam - the z. B. is expandable by compressed air, and this can be a compressible layer, then a semi-compressible layer, which will be fiber reinforced can, and then a printing top layer can be arranged, which is very advantageous is.
  • Fig. 2 shows a carrier sleeve 3.1 with Associated transfer cylinder 1.1 with a correspondingly tapered outer surface.
  • Radial bores 1a are arranged on the lateral surface, which are connected to them via a line supply compressed air against the inner surface of the carrier sleeve 3.1 and this to Widen your transition easier.
  • the carrier sleeve 3.1 is partially shown in longitudinal section in FIG. 3. it consists of a metal, advantageously nickel. Its outer surface is cylindrical, taking accordingly their wall thickness towards the end with the smaller inside diameter.
  • the Carrier sleeve 3.1 can be created, for example, by electroplating and then ground become.
  • the 4 contains an inner carrier 11 made of metal, advantageously nickel, with an inner and outer conical surface.
  • the carrier 11 can be formed from a sheet metal, with the bent towards each other Form a joint.
  • the joint can also be welded, for example using a laser beam.
  • On the carrier 11 is a solid plastic layer 12 with a cylindrical outer surface arranged. Hard rubber is advantageous vulcanized or glued on and then sanded.
  • the plastic layer 12 can be carried out with or without impact.
  • the carrier sleeve 3.3 partially shown in FIG. 5 consists of glass fiber reinforced Plastic (GRP).
  • GRP glass fiber reinforced Plastic
  • the carrier sleeves shown 3.1 to 3.3 carry, not shown, one of the coatings described above.
