Abstract
An apparatus for manufacturing a tire comprises a former for forming a carcass ply or the like to a cylindrical configuration, a bead holder for placing bead cores on the cylindrical carcass ply and then effecting assembly of a carcass ply-bead core structure. A drum receives the structure from the former and effects assembly of a cylindrical carcass layer and then deforms the latter into a trochoidal configuration to obtain a green tire. The carcass ply located between both the bead cores on the structure is caused to expand and the structure is placed on the drum, the bead cores are wrapped with the end portions of the carcass ply and then the green tire for the radial tire is assembled by attaching side wall members or the like.
