<p>A tire building apparatus includes a forming drum (9) rotatably supported with its one end and having an outer circumference around whioh a tire constituting member (T) is wound, and bead setters (35) for setting beads (B) in position on the tire constituting member. The apparatus further includes bead supply device (41) having a holder (44) fixed to a forward end of a main shaft (10) of the forming drum and a plurality of grasping pawls (61) supported by the holder and radially movable toward and away from an axis of the main shaft in synchronism with each other to be able to grasp th beads on the inside thereof. With this arrangement, beads are brought into exact alignment with the forming drum to eliminate contact of the beads with the tire constituting member in setting the beads. As a result, damage of the tire oonstituting member can be prevented to improve yield rate of tire building.</p> |
