ABSTRACT:
A green tire building apparatus includes a plurality of bead locking segments arranged in a circle concentric with the main body of the shaping drum of the apparatus. A resilient annular member is mounted in an annular groove in the outer periphery of the bead locking segments, and the bead locking segments and annular member are moved radially outward for pushing a layer of tire material on the shaping drum against a bead which is disposed thereon. The movement is accomplished by a piston/cylinder and link mechanism. A turn-up bladder is arranged over, but separate from, the resilient annular member.
