  • the intermediate layer can e.g. B. from the same elastomer material how the printing layer is made.
  • a rubber blanket can also have more or fewer layers than the one here described compressible layer, the reinforcing layer and the printing layer include. If it is e.g. B. is required for a specific application, a after rubber blanket produced by the method according to the invention also a sleeve-shaped Base and a printing layer or a sleeve-shaped base, a compressible Include layer and a printing layer.
  • Processed rubber blanket can also have several compressible layers, comprise several intermediate layers and / or several reinforcing layers.
  • the use of partially overlapping strips has the advantage that a greater isometry of the reinforcing layer is guaranteed.
  • a single strip to form the reinforcing layer.
  • the single plastic strip on one side with be coated with a compressible material so that a reinforcing layer and a compressible layer, or on one side with a Transfer of the printed image suitable elastomer material, so that a reinforcing layer and a printing layer simultaneously in one winding process arise.
  • the individual strip on one side a compressible material and on the other hand with one for transferring the Suitable elastomer material is coated, so that a compressible Layer, a reinforcing layer and a printing layer arise.
  • the stripe it can also be completely uncoated, so that only a reinforcing layer is formed becomes.
  • the reinforcing layer which in the preferred embodiment is made of plastic strips 40 and 41 is formed, can also consist of partially overlapping strips of fabric be formed.
  • the reinforcing layer is independent is applied by the printing layer and the compressible layer, the reinforcing layer also by wrapping the workpiece with fabric or Plastic threads or cords are formed.
  • ductless rubber blanket preferably in Connection to the manufacturing process can be provided with a longitudinal section, which at least cut through the outer print layer, provided this is for the printing process is desirable.
