Definitions

  • the invention relates to a method for replacing the shell of a roller for guiding, in particular for pressing sheet-like materials according to the definition of the claims.
  • Known rolls for the guidance or pressure treatment of web-shaped materials have a substantially cylindrical geometry. Inside, they consist of a load-bearing, hard core, of metal, for example steel, and of an elastomeric sheath enclosing the core on one longitudinal side and firmly connected to it. For example, find such rolls application as a bending presses for gravure printing systems, where they ensure a uniform pressing against a counter roll.
  • the document DE-195 17 653 shows an improvement in this respect by the structure of the Elastomerlagenwickels and its vulcanization is separated into a jacket and the mounting of the shell on the core.
  • the jacket is prefabricated as a sleeve and pulled under pressure on the provided with primer core. Due to the separation of the process steps, a fully automatic production of the jacket is possible. Also, transportation and storage of the rollers simplified, since only change coats must be delivered. Finally, the pulling up of the jacket on the core takes place quickly.
  • the elastic sheath is exposed to high frictional forces during operation. Also done in the coat large Walk. As a result, the roller is heated to a considerable extent, which heat must be dissipated through the core. Due to the different coefficients of thermal expansion of the core and sheath materials, as well as due to the imbalance caused by flexing work, high mechanical stresses occur in the roll. In particular, high mechanical stresses occur at the connection from the core to the shell, which weakens and dissolves the connection between core and shell and leads to failures. It is therefore desirable to have a permanently stable, high strength bond between the shell and core to reduce the failure rates of rolls during operation and to increase the life of the rolls.
  • a worn coat is renewed by turning the jacket material down to the core. In this case, injuries to the core often occur through the turning tool, which leads to failures.
  • the core is then cleaned and provided with adhesion promoter. Finally, a new coat is raised. It is therefore desirable to have a simple, quick and safe method of shell change to reduce the failure rates of cores when changing shells and to change a sheath faster.
  • a roller which has a carrier tube made of fiber-reinforced synthetic resin between the lining and the axle.
  • the support tube is rotatably mounted on the axis.
