ABSTRACT OF THE DISCLOSURE APPARATUS AND METHOD FOR ROLLING BEAD RINGS Upper and lower rollers have grooves for a bead ring having a clamp area portion produced by a bead winding machine. The bead ring is placed in the groove of the lower roller with the beginning of the clamp area portion in position for pressing by lowering of the upper roller so that the bead ring is engaged by the groove in the upper roller. The rollers are oscillated between the pressing position at the beginning of the clamping area and the end of the clamping area to roll the top, bottom and sides of the clamping area portion during the move- ment of the bead ring. The pressure on the bead ring is released by raising the upper roller at the initial pressing position at the beginning of the clamping area so that the bead ring may be removed with the same orien- tation it had when it was placed in the groove.
