Abstract

Damaged areas of tyre treads are locally enclosed by a flexible covered adhesive bonded at its edges and fitted with an adaptor to allow evacuation and/or pressurisation of the tyre surface beneath the covered area. Adhesive must be effective at normal vulcanisation temps. Esp. for local repairs on large tyres as used for public service vehicles, off-the road vehicles etc. Also suitable for repairs or build-up of internal tread or sidewall surfaces. Small flexible covers are adaptable to parts of many different sizes and shapes of tyres, are cheaper and more effective than vacuum/pressure chambers designed to enclose complete tyres. Patch rubber may be enclosed within the envelope and consolidated and cured prior to removing the envelope.
