Abstract: When a bead member formed of a bead core and a bead filler is transferred, the occurrence of deformation in the bead filler is restricted, and the shape accuracy thereof is improved. A plurality of supporting pawls provided on a transfer apparatus are brought into contact with an inside diameter portion of a bead core of a bead member to support it at a plurality of points in the circumferential direction, from the inner circumferential side. At the same time, an end of a bead filler is sucked and supported by suction pads joined to the supporting pawls via joint members. The bead member, while being held at the respective parts, is removed from a forming apparatus, is moved to a cartridge for storage, and is placed on a placing surface of the cartridge. Thereafter, the suction holding of the bead filler is released and the supporting pawls are moved away from the inside diameter portion of the bead core, thus transferring the bead member onto the cartridge.

Abstract: A tire building drum comprises a main drum shaft, a pair of movable bodies, approaching-separating means for moving these movable bodies in opposite directions, plural bead lock segments movably supported by each of the movable bodies in a radial direction, enlarging-contracting means for synchronously moving these bead lock segments in the radial direction, a seal member, a hollow cylindrical body and plural turnup fingers, wherein the seal member comprises an inner elongated portion extending inward from its base end part airtightly fixed to the movable body in the axial direction and an outer elongated portion extending outward from an inner end of the inner elongated portion in the axial direction.
