Abstract
Abstract A tire building drum has adjacent respective edges of a cylindrical drum section a plurality of radially movable segments. The circumferential outer surface of the segments forms an arcuate surface. A plane of separation between the segments and the drum section edge intersects the arcuate surface at approximately the most radially inward portion of the arcuate surface. The tire building drum is particularly useful for positioning the bead wire ring during the turn-up of a metal reinforced carcass ply.
