摘要： 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 through 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 are continually driven in the above steps.
