ABSTRACT:
A tire repair device which vulcanizes an uncured rubber repair plug built in a damaged area of the tire. The frame of the device is in the form of a C-clamp having a heated backing plate which opposes a heated pressure pad. The pad is carried in a cylinder which also receives a sealing piston forming a pressure chamber behind the pad. Air under pressure is applied to the pressure chamber to force the pressure pad against the damaged area of the tire during vulcanization. The pressure pad is flexible in order to conform to the tire surface against which it is pressed in opposition to the backing plate.
