Abstract
Webs of paper or cardboard are rolled up using carrying or supporting rollers or pressing rollers with a hollow cylindrical body of a rigid material to which a deformable layer is applied. The deformable layer consists of a cellular plastic material partly with open pores and partly with pores which are closed on themselves and in which the pore size can be less than 5 mm. The compression modulus of the material is less than 10 MPa.
