Abstract
A coil-winding machine is disclosed in which an annular member on which wire is to be wound is inserted into a traveling ring and a shuttle and held in position. A predetermined length of wire is stored in the shuttle. The trialing end of the wire stored in the shuttle is fixed on the annular member. The shuttle is rotated in the direction of storage, while at the same time rotating the traveling ring in the direction of storage by the tension of the wire or a turning effort transmitted from a driving system, thus winding the wire on the annular member in the direction of storage. After forming a crossover wire, the wire is fixed on the annular member. The traveling ring is rotated in the direction opposite to that of storage. At the same time, the shuttle is rotated following the traveling ring with brake applied to the shuttle, or a turning effort in the direction of storage is transmitted to the shuttle through a clutch adapted to slip in response to a torque more than a setting, so that the required tension is applied to the wire, thus winding the wire on the annular member in the direction opposite to that of storage. In this way, the wire is wound in different directions in one process.
