Method for making a cover for a roll core having a multiple layer construction and having minimal residual stresses

摘要

A method is disclosed for producing a covered roll having a multi-layered construction. A first embodiment includes a plurality of steps. The first step is to provide a cylindrical roll core having two ends, a length therebetween, and an outer surface. Next, a dry fiber mat layer is tightly wrapped over the roll core outer surface. A fabric, in the form of a strip, is impregnated with a thermoset resin such as epoxy or urethane. The roll core is then rotated and the thermoset resin impregnated fabric strip is helically wound over the tightly wrapped dry fiber mat layer. Tension is maintained while winding the thermoset resin impregnated fabric strip to form a fabric layer.
