Definitions

  • the invention relates to a sleeve for rollers of printing machines, in particular for Anilox rollers of rotary printing presses, consisting of an inner tube made of stretchable plastic material, preferably duromer, on the outer one Layer of an elastomer, preferably PU, is applied, on which a dimensionally stable Jacket tube is firmly connected via carrier material.
  • the carrier material consists of a foamed rigid foam, by means of which an intimate connection of the outer jacket tube to the two-layer inner tube is produced.
  • the rigid foam used as the carrier material is susceptible to thermal, chemical and mechanical stresses.
  • the use of rigid foam enables the production of lightweight sleeves.
  • a pressure roller is known, the material of which extends axially Ribs is worn, which intersect in the cylinder axis, so that there is no need for a shaft on which the jacket tube is attached would.
  • radially extending ones Ribs are provided, but not the outer casing tube with an inner one Connect the casing tube, but only serve as bracing.
  • a pressure cylinder is known from US Pat. No. 3,640,218, which has a helical shape is provided over its circumferential surface groove in which to attach a an inflatable tube is inserted.
  • a pressure roller is known in which a nylon sleeve is attached to a shaft provided with corrugations, which is provided with circumferential ribs and axial guides. Due to the elasticity of the ribs, a tube can be pulled onto the roller formed in this way.
  • a pressure roller which consists of a roller core and a pressure cylinder carried by the latter, the non-positive connection between the roller core and the pressure cylinder consisting of inflatable bodies which are formed by a multiplicity of cells which extend in sections the roller core connected and connected via radial bores to the interior of the roller core, which is designed as a compressed air reservoir.
  • the object of the invention is to design a sleeve of the type specified in the introduction, that it is light on the one hand and a durable, resilient on the other Connection between the casing tube and the two-layer inner tube is created.
  • this object is achieved in that the carrier material is formed from circumferential webs made of metal .
  • a web is expediently provided, which is helical over the entire axial length of the sleeve runs.
  • annular webs are provided.
  • the casing tube and the webs are made in one piece from aluminum produced by centrifugal casting.
  • the centrifugal casting process has the Advantage that the jacket tube with the webs is made completely stress-free.
  • each web has at least one in the axial direction opening on the sleeve. This ensures that the later coating of the sleeve with a raster material heat can be dissipated well.
  • Another essential feature for the manufacture of a sleeve can be seen in the fact that on the inside with a stretchable tube provided with an elastomeric layer and an inner web Jacket tube is shrunk. The shrinking process makes it a safe one Connection between the jacket tube and the two-layer inner tube guaranteed.
  • a sleeve for pressure rollers which consists of an inner expandable tube 2 consists of GRP.
  • An outer compressible layer 3 is on this GRP pipe applied, which consists of elastomer, for example PU.
  • the two-layer inner tube is surrounded by a dimensionally stable jacket tube 4, which is firmly connected to the two-layer inner tube via webs 5.
  • a dimensionally stable jacket tube 4 which is firmly connected to the two-layer inner tube via webs 5.
  • the outer is when using a sleeve as anilox roller Jacket tube with an engravable layer, for example coated with ceramic. A lot of heat is generated during this process. To dissipate this heat well can, the webs 5 with in the axial direction of the sleeve 1 through holes 6 provided. The application of the casing tube 4 with the webs 5 the two-layer inner tube 2, 3 takes place in the shrinking process, so that a safe Attachment is guaranteed.
  • the advantage of such a sleeve is essential in that they are lightweight on the one hand and on the other hand against thermal, chemical and mechanical loads are extremely resistant.
