ABSTRACT:
This invention relates to a method of recapping tires. The tire to be recapped is placed within an envelope with the recap thereabout. A hose runs from inside the envelope to outside the tank in which the tire is placed. Hot water is pumped into the air-tight tank. The rising air and water pressure force the air out of the envelope and press the envelope firmly against the recapped tire to hold the recap securely in place. As water leaks in the envelope cause rejects, the present method advances the art by allowing for an early detection of leaks in the envelope. As well, the usual methods remove the air from the envelope by creating a vacuum in the tank. This method uses the simpler process of creating a higher pressure in the tank to force the air out of the envelope.
