Patent ID: 7749413

Claim:
A method of resurfacing a cylindrical member comprising: providing a cylindrical member comprising an outer surface comprising a low surface energy, semicrystalline thermoplastic wherein the low surface energy, semicrystalline thermoplastic is a fluorothermoplastic comprising a fluoropolymer resin selected from the group consisting of polytetrafluoroethylene, polyperfluoroalkoxy-tetrafluoroethylene, polyfluorinated ethylene-propylene, polyvinylfluoride, polyvinylidene fluoride, poly(ethylene-chloro-trifluoroethylene), polychlorotrifluoroethylene and blends thereof; engaging the outer surface of the cylindrical member with at least one heating roller at an initial pressure of at least 5 psi and at an initial temperature of between 10° C. below the melt temperature and the melt temperature of the thermoplastic using an internal heater; rotating the cylindrical member while engaged with the at least one heating roller for a time sufficient to resurface of the outer surface of the cylindrical member; accessing processing adjustment parameters; adjusting one or more of a pressure, temperature and time of heating; and controlling the engaging and rotating steps accordingly.
