A plurality of beads with bead fillers are disposed on each of chain conveyors and in a bead stock device. The beads are delivered to a pair of bead holding portions of a bead chuck by a bead removal plate. The bead chuck is fixed to an arm portion of a conveyance robot. The bead chuck is raised, slid, and lowered due to the rotation of drive motors. A pair of beads with bead fillers is thereby supplied to a bead setter within a tire forming machine.
