ABSTRACT:
A roll for selective use as either a support drum or as a rider roll in a winder for winding a traveling paper web into a relatively large diameter wound web roll has a body with an outer, elastomeric cover. The elastomeric cover includes a pattern, open to the surface, arranged such that the percent of volumetric void for a unit of cover volume is such that the effective hardness of the cover ranges between about 30 Shore "A" to about 55 Shore "A" where the roll is a support drum, and between about 40 Shore "A" to about 65 Shore "A" when the roll is a rider roll. In addition, the elastomeric material has an absolute hardness of about 65 Shore "A", or less, for a support drum, and about 75 Shore "A", or less, for a rider roll, and a Poisson's ratio of between about 0.47 to about 0.499.
