Abstract
A roller (10) used as support, backing or driven roller in winding devices, such as winders for winding wound rolls of paper coming from a papermaking machine, is composed of an outer cylindrical roller element (24), on which an elastic, flexible intermediate layer (26) of elastomeric material is applied. On the intermediate layer (26), an external roller mantle (33) of thin-wall spring steel is provided that can be deformed in a plane perpendicular to the axis due to the contact pressure of the roll (2) and can be pressed against the outer perimeter of the roll (2). A broad contact region is created, which leads to a lower specific nip pressure and to a lower roll hardness. Channels (27, 28) in the intermediate layer (26) serve to increase the flexibility and cooling.
