Claims (1)

(57) [Claim 1] A rotatable drum, a belt arranged along the outer periphery of a part of the drum and holding and guiding a wire between the drum and the belt, And a holding member that is arranged on a part of the outer periphery of the drum where the wound member is not held, and guides a tip of a wire guided by the drum and the belt to a winding window of the wound member. An inlet guide and a wire inserted through the winding window of the wound member are guided so as to be sandwiched by the drum and the belt, and move downward when the tip of the wire reaches a predetermined position on the outer periphery of the drum. And an outlet guide for temporarily releasing the holding of the wire by the belt and the drum. The inlet guide is provided with a wire positioned below the drum when the holding by the belt and the drum is released. When the hook portion reaches the entrance guide, the entrance guide is formed to release the guide of the wire and move the wire below the drum, and the exit guide moves downward in the exit guide. A winding slit formed to release the guide of the wire and move the wire below the drum.
