发明名称 Process and apparatus for manufacturing vehicle tires
摘要 This invention provides a method and apparatus for making vehicle tires wherein the annular, reinforcing structure and the tread band are manufactured on two drums, one drum having a comb-shaped surface, and the other drum having sectors. The comb-shaped drum is co-axial and can be slipped off with respect to the drum having sectors. Means are provided for rotating the two drums independently of one another in a slipped position, and for centering the teeth of the comb when the two drums are one around the other. After centering, the sectors are expanded, from the inside towards the outside of the comb, for sustaining the annular structure previously disposed on the comb in a slipped position from the sectors and for receiving the tread band.
