A winding apparatus has a rotating unit on which a video head having a through hole is mounted. A wire is fed through the through hole and drawn taut. The video head is pivoted 180.degree. by the rotating unit so that the wire stretched is wound around the head. Then, a first wire feeding unit clamps the end portion of the wire, is pivoted 180.degree. and moved to the vicinity of the head to direct the end of the wire to the through hole. Thereafter, the first feeding unit feeds the wire trough the through hole from one end thereof, and the wire is stretched thereby winding the wire around the head. The head is then pivoted 180.degree. by the rotating unit to wind the wire around the head. Thereafter, a second wire feeding unit clamps the end portion of the wire and is pivoted 180.degree. and moved to the vicinity of the head to direct the end of the wire to the through hole. The second feeding unit then feeds the wire through the through hole. Thereafter, the apparatus is continually driven in the above steps.

Toroidal core winding apparatus

A winding apparatus has a holding unit on which a video head having a through hole is mounted. A wire is supplied by a wire supply unit through the through hole from one end thereof. A first wire suction unit draws by suction the wire from the other end side of the through hole and is moved away from the video head to render the wire taut. The video head is pivoted 180.degree. by the holding unit so that the wire stretched is wound around the head. Then, a first wire feeding unit clamps the end portion of the wire at the first suction unit side, and is pivoted 180.degree. and moved to the vicinity of the head to direct the end of the wire to the through hole. Thereafter, the first feeding unit feeds the wire through the through hole from one end thereof, and the wire fed is drawn by a second suction unit from the other end side of the through hole. The second suction unit is then moved away from the head to stretch the wire between the head and the second suction unit, thereby winding the wire around the head. The head is then pivoted 180.degree. by the holding unit to wind the wire around the head. Thereafter, a second wire feeding unit clamps the end portion of the wire at the second suction unit side, and is pivoted 180.degree. and moved to the vicinity of the head to direct the end of the wire to the through hole. The second feeding unit then feeds the wire through the through hole. Thereafter, the first and second suction units, the first and second feeding units, and the holding unit are continually driven in the above steps.
