ABSTRACT:
A bead locking apparatus includes bead support segments disposed in an annular arrangement at each of the axially opposite ends of a building drum mounted on a rotary shaft, the support segments being movable outward or inward radially of the drum, an elastic ring fitted in an annular recess formed in the outer periphery of the annular arrangement of segments, a segment drive device for moving the bead support segments radially outward, and a device for radially expanding the elastic ring independently of the segments. The bead is first primarily locked by the elastic ring and then secondarily locked by the support segments.
