Abstract: A calender roll, which was already in use and has a metallic core with engaged textile material sheets, can be worked for a new use. In the surface of the sheets are cut grooves, to which is subsequently applied a layer structure of synthetic resin-impregnated fibrous material forming a certain thickness over each point of the roll. Onto said layer can be applied a functional covering, for example of rubber.

Abstract: A process for producing a resilient roll having a hard roll core (e.g., of metal) and a resilient covering layer. In forming the covering layer, a radially inner connecting layer is applied to the roll core and a radially outer functional layer is applied to the connecting layer. In addition, in forming the connecting layer, a fiber bundle comprising a large number of fibers is wound onto the roll core, the winding direction of the fibers running essentially parallel to one another and at an angle to the circumferential direction of the roll core. A number of layers are wound one above another, with the angular position (i.e., orientation), as defined by the winding direction with respect to the longitudinal axis of the roll, of fiber bundles in respectively successive fiber layers being different. A roll according to the present invention comprises fiber layers each including a plurality of fibers wound at an angle to the longitudinal axis of the roll core and running essentially parallel to one another.
