Abstract

The vulcanization sleeve described is designed to be air-tight at least in the tyre processing region to allow evacuation of air and gaz bubbles from the space between the sleeve and the tyre or the tread or tread cap, and it covers the processing region during vulcanization in an autoclave. The problem is to find a solution which while maintaining the advantages of the so-called cold process enables during vulcanization a considerable increase in the longevity of the sleeves, a simplification in handling and in particular the application by vulcanization of treads in the form of sections of otherwise endless pieces of tread. This is achieved by the fact that the vulcanization sleeve is made of a plastic foil (6) of thermoplastic polyurethane, and in the event of a partial covering of the tyre, this sleeve is provided possibly with a sealing ring (7).
