Abstract:
1. A bead wire winding and forming device comprising: a rotatable former to wind a rubber-coated bead wire therearound to form an annular bead core; a guide device to guide the bead wire to the former; and a cutting device to cut a rear end portion of the bead wire wound around the former a predetermined amount; wherein the guide device comprises: a movable body supported movably in a tangential direction of the former and being capable of clamping and unclamping the bead wire, a guide body supported on the movable body to be moved together with the movable body in the tangential direction and having a guide portion for guiding the head wire in the tangential direction of the former, the guide body being allowed to be swung by the bead wire guided at the guide portion in a plane extending in parallel to the tangential direction of the former, and a restriction member engagable with the guide body for allowing the guide body to be swung in the plane when the movable body is at a retracted position, in the tangential direction during the winding of the bead wire around the former, and for restricting the guide body to not be swung in the plane and to set the guide body to a predetermined position in the plane when the movable body is at an advanced position in the tangential direction for setting a starting end of the bead wire on the former.
