Abstract
A process for producing a resilient roll having a hard roll core (such as a 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 and/or the functional layer, glass fibers and carbon fibers are wound simultaneously onto the roll core, the mixture ratio of glass fibers to carbon fibers being between about 60/40 and 90/10. A roll has an inner connecting layer and an outer functional layer comprising a mixture of glass fibers and carbon fibers, which are embedded in a matrix material and are distributed uniformly over the length of the roll. The mixture ratio of glass fibers to carbon fibers is between about 60/40 and about 90/10.
