ROLLER FOR A WINDING MACHINE

摘要

It is known that in order to wind up webs (1) of paper or cardboard it is possible to use winding machines with rollers that have a hollow, cylindrical support body (7) that is of rigid material, with a deformable layer applied to its outside surface. The deformable layer (9) is of a cellular plastic material that incorporates a large number of evenly distributed pores, the size of which is smaller than 5 mm, and is preferably between 0.05 and 1 mm. The pores include partially open pores and closed pores. The compression modulus k is less than 10 MPa. It is preferred that the roller according to the present invention be used in the winding machine as a carrier roller (5) or a pressure roller (6).
