Abstract (en)

[origin: EP1681254A2] The roll winder drum (W) has a core (15) which radially on the outside has a functional fitting (17) in which is inlaid damping material (18). The functional fitting is incompressible and the damping material is compressible. The damping material is selected from the polyurethane (PUR), isoprene-isobutyl-copolymer (IIR) and fluorcarbon-elastomer (FCM) group of materials. The damping material extends as far as the drum surface (20). The functional fitting and the damping material may have the same hardness.
