RETREADING RADIAL TYRES

摘要

This invention is directed to the retreading of steel belted radial tires by removing and replacing more than the protector ply. Initially, the tire is inspected to determine if it is retreadable. The tire is then buffed so that the protector ply will be located and removed. The first working belt is then located and removed. A steel belt incapulated in uncured rubber will be placed on the tire. Then wedge stock will be applied, isolating the replacement belt. A second replacement belt will be applied for the protector ply with the steel cords going in the opposite direction of the first replacement belt applied. Precured tread rubber will be applied to the casing surface in the usual manner. The assembly is then covered by an envelope and a metal curing band will be applied to the outer surface. The assembly will then be mounted on curing rims and cured in commercially available equipment.
