A winding apparatus forms bead rings (B) by winding a single wire (W) around the outer periphery of a circular former (13) such that said wire is aligned in rows and columns. In the apparatus frame (11), a roller (16) for pressing the wire (W) on the outer periphery of the former (13) is provided such that the roller (16) can move in the row direction and column direction of the wire (W). A circular cam (20) having a cam surface (22a) is supported on a cam shaft (18) which rotates in synchronization with the rotation of the former (13). A cam follower (17) that moves integrally with the roller (16) in the row direction and column direction of the wire (W) is engaged on the cam surface (22a) of the cam (20), such that the roller (16) moves in the row direction of the wire (W) by means of the action of the cam surface (22a). |
