PROCESS AND APPARATUS FOR BUILDING TYRES

摘要

Auxiliary support members are brought into engagement with a building drum provided with a first outer circumferential surface. These auxiliary support members each have a second outer circumferential surface which extends in the continuation of the first outer circumferential surface. A separation element having a circumferential support surface is provided at a radially external position on each of the auxiliary support members. A component of the tyre is applied around each of the circumferential support surfaces and the auxiliary support members are subsequently axially moved away from the building drum, so as to radially contract the circumferential support surfaces to decouple them from the respective components of the tyre.
