  • the expansion layer is advantageously provided with a groove into which a part of the material of the Expansion layer can be displaced when applied to a carrier cylinder. This will the application on the carrier core easier and the necessary for the frictional connection Frictional force set.
  • thermally deformable raw materials are used Tubes or hoses used. These tubes or hoses are made with the help of heat applied to or pushed onto a manufacturing core, this Manufacturing core a cylindrical tapered in an axial direction Has outer circumference. The mounting on the manufacturing core is convenient from the tapered side of the manufacturing core. After winding up, they are left thermally cool deformable pipes or hoses or the entire system so that the thermally deformable material consolidated. The material now solidified is so easy and quickly adopted the desired shape, with an extremely smooth surface, that meets the highest demands. The sleeve is made after Cooled deducted from the manufacturing core.
  • the heat is preferably supplied via the manufacturing core, the manufacturing core can be heated by an upstream heating process. That is preferred Manufacturing core but also during the postponement of the thermally deformable material Supplied heat. This enables a particularly smooth and smooth process.
  • the manufacturing core is by means of a heat transfer liquid or a heat transfer gas heated or cooled.
  • this means that the Temperature on the other hand a quick change in temperature, in particular a change from heating the manufacturing cylinder to cooling the manufacturing cylinder after the corresponding molding process is completed.
  • Pushing the tubular semi-finished product onto the production cylinder is preferred with a pressing device, in particular an automatically operated mechanical Thrust device, performed while the finished sleeve using a wiper after the consolidation is stripped from the manufacturing core. These operations will be advantageously carried out automatically.
  • a functional profile or a functional layer can then be introduced onto the finished sleeve be stuck on.
  • the functional profile is particularly by means of a direct structuring by a laser beam, ablation from the ionized state or a mechanical Machining introduced while the functional layers are made of different materials, in particular PU, PTFE, copper or plastics, which are preferably based on Sleeve can be glued on, but also with all other common methods can be attached to the surface of the sleeve.
  • the functional layer can also be a wear protection layer, for example.
  • Breakthroughs, bores and the like through the sleeve are also intended as a functional profile be understood. It is also possible to retrofit the sleeve with perforations according to Art a sieve. Then such a sleeve can be used, for example, as a rotary screen Screening of bulk goods or as a suction cylinder, for example to suck in foils or to Pulling water out of paper can be used.
  • an expansion layer can be made on the inside of the sleeve in a subsequent step be attached.
  • the expansion layer consists of a compressible material, preferably are foams, elastic materials with a gaseous filling, for example expanded Polystyrene beads, or elastic materials with a structure are used, whereby The structuring provides volume similar to that of the gaseous filling It can be displaced as soon as the sleeve is pushed on, creating a special one Compliancy and elasticity and increased compressibility is provided.
  • the expansion layer usually performs several essential functions: on the one hand, it provides it by the energy that is stored in it by the compression, for that for a frictional Connection necessary force or pressure between the expansion layer and carrier cylinder, on the other hand, it ensures an even distribution of pressure, what Damage especially when pulling or pulling the sleeve onto the carrier cylinder avoids. Furthermore, the expansion layer may be necessary if the sleeve is pneumatic from the carrier cylinder, for example by blowing compressed air between the Outer layer of the carrier cylinder and the inner layer of the sleeve or the expansion layer, deducted becomes. Finally, the stretch layer also compensates for any unevenness on the inside of the tubular base body.
  • a groove is preferably made in the expansion layer and extends at least over a partial area of the radial expansion of the expansion layer, preferably less than 50% of the radial expansion of the expansion layer.
