ABSTRACT:
A hard roll is produced by a process utilizing the steps of winding a fiber material impregnated with a thermosetting resin around the outer peripheral surface of a metal roll core to form a fiber-reinforced lower winding layer, then injecting a thermosetting synthetic resin material into a mold of predetermined size and curing the material at a specified temperature to form an outer layer hollow cylinder separately from the first step. The next stepsave fitting the outer layer cylinder around the roll core covered with the winding layer, and injecting an adhesive of low viscosity into an annular clearance between the winding layer and the cylinder and then curing the adhesive at a specified temperature to bond the winding layer to the cylinder with the layer of adhesive.
