Bead wire winding device and winding method

A bead wire winding device comprising:

• a molding support body connected to a rotational shaft, at least one winding guide which is rotated with the molding support body, and which approachingly and retreatingly displaces with respect to each side portion of the molding support body and enlarging and reducingly deforms, and a wire supply means which supplies a bead wire to a wire seating portion of the winding guide within a space defined by each winding guide which is in an approached state with respect to a respective side surface of the molding support body, and in an enlarged diameter state,
• wherein the winding guide comprises a plurality of radially displacing members, which can be displaced in a radial direction, connected to a boss portion rough link members, each of the radially displacing members having a protrusion provided which is located radially inward of an outer periphery of the respective radially displacing member and which forms a wire seating portion, and advance/retreat driving means of the boss portion being disposed that advancingly and retreatingly drives the boss portion with respect to the molding support body, a clamping claw provided on at least one of the radially displacing members, the clamping claw being constantly urged in a closing direction and pinching a tip portion of the beard wire, and a driving means being provided that causes opening displacement of the clamping claw.
