Definitions

  • the invention relates to a roll cover made of a fiber composite material and a method for its production.
  • Roll coverings made of fiber composite materials are used in web-processing machines in a variety of ways. The most demanding requirements are placed on elastic calendar covers with regard to compressive stress and dynamic stress on paper machines. These covers are usually constructed of fiber composite material.
  • the so-called filament winding method in which fiber bundles are wound onto a roll body and then joined together by means of resins to form a fiber composite material.
  • the disadvantage is that the finished roll cover is made up of different layers.
  • the interface between different layers is often here, due to the sudden change in material properties, the starting point for Delaminationserscheinonne in roll cover.
  • the second application method is not suitable, for example, for the production of wear layers to be brought into contact with the paper web in straighteners, since such roll shells lead to an uneven smoothing of the paper web, since the wound fibers are substantially rectified.
