Apparatus and method for manufacture of tires

Abstract

An apparatus for manufacture of a tire, the apparatus including a drum with shoulder having a generally cylindrical main receiving surface to receive the products to be assembled, the main receiving surface being radially retractable. The drum has a shoulder axially to the side edges of said main receiving surface. The drum is mounted on a shaft. At least one associated axially movable side crown is mounted coaxially with the drum. The drum has a lateral protuberance coaxially juxtaposed to at least one of its shoulders. The side crown is axially slidable at least partly under the lateral protuberance, the lateral protuberance forming a quasi-cylindrical support surface whose outside diameter is smaller than the diameter of the main receiving surface. The side crown has a substantially cylindrical outer surface capable of passing axially outside of the lateral protuberance.
