RADIAL TIRE FORMING APPARATUS

摘要

The present invention provides a radial tire forming apparatus capable of being applied to the formation of a carcass band having a large folding length. On a housing for a rollover device of the tire forming apparatus, a plurality of sets of straight rail bearers are fixed at appropriate places, so that a frame provided with rails is advanced toward or retreated from a second forming point on the carcass forming former side by a cylinder fixed to the housing. The diameter of a first rollover ring is slightly smaller than the diameter of a second rollover ring. When the rollover rings are brought closest to each other, the cylindrical portions of the rings enter and lap on each other.
