ABSTRACT OF THE DISCLOSURE A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunc- tion with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are turned up and reversely wrapped around the tire bead rings to anchor the rings to the unvulcanized tire carcass for further processing. The carriers span the bead seats of the bead lock segments and snugly fit around the adjacent turn-up bladders, so that the bead lock segments, upon radial expansion, pull against and distort the shape of the bladders which react to regain their shape and/or position by pushing back against the carriers to tension the carriers which are in contact with the ply endings and which tension the ply endings during turn-up to eliminate, adjacent the tire bead rings, the formation of voids which entrap air and adversely affect the adhesion between the tire bead rings and surrounding rubber material. A lubricant is provided between the contacting surfaces of the carriers and turn-up bladders to permit relative, unimpeded movement between these two components.
