Abstract

This disclosure relates to sleeved rolls and more particularly, to a method of manufacturing sleeved fuser rolls or pressure rolls for a fusing apparatus utilized in fixing toner images to support sheets in a xerographic copying apparatus wherein the roll comprises a rigid core and an outer layer over the rigid core, the outer layer preferably comprising a fluorocarbon polymer. In more preferred embodi-ments, the fluorocarbon polymer is a copolymer of perf luoroalkyl perf luorovinyl ether with tetrafluoroethylene. The outer sleeve layer is placed over the core in the form of a heat-shrinkable sleeve comprising the copolymer material. In U.S. Patent 3,912,901, copolymers of perfluoroalkyl perfluorovinyl ether and tetra-fluoroethylene are placed as an outer sleeve material over a silicone rubber resilient material adhered to the core of a pressure roll for a xerographic apparatus.
