Abstract
A rubber-covered roll has a cylindrical roll core and a cylindrical sheath of rubber molded about and covering the roll core to provide a rubber-covered roll core. The roll also has a pair of metallic end cap cores and a pair of rubber jackets each molded about one of the end cap cores to partially enclose the same and provide a pair of rubber-jacketed end caps. The rubber-jacketed end caps are attached to opposite ends of the rubber-covered roll core to provide the rubber-covered roll. Each end cap core is annular-shaped and has an inner corner beveled at an approximate forty-five degree angle to define a continuous inner corner surface thereon. Each rubber jacket is molded about the periphery of one of the end cap cores, including about the inner corner surface thereon, to provide the rubber-jacketed end cap core which when attached to one of the ends of the rubber-covered roll core coacts therewith to interlock therebetween an inner portion of the rubber jacket covering the inner corner surface of the end cap core.
