ABSTRACT:
An apparatus and method for cold retreading of the running surface of a vehicle tire. A rubber and cloth mold is produced utilizing a new tire male mold covered with perforated polyethylene film, uncured rubber and highly stretchable cloth enclosed in an envelope and cured by application of pressure and heat. The somewhat flexible female mold thus produced is then utilized in recapping tires by positioning it around a prepared tire carcass coated with cement, a layer of uncured rubber, and a sheet of perforated polyethylene film. The mold and tire assembly is then enclosed in an envelope, and like assemblies are placed in a chamber where curing of the rubber layer is accomplished by inflation of the tire carcass, evacuation of the envelope, pressurization of the chamber and application of heat.
