Abstract
A winding machine includes a winding core around which a winding is wound, a first winding jig and a second winding jig positioned with the winding core interposed therebetween in an axial direction of a central axis of the winding core, and a first gripper and a second gripper that are located on an outer side of the winding core in a radial direction around the central axis. An outer edge portion of the first winding jig in the radial direction and an outer edge portion of the second winding jig in the radial direction are located on an outer side, in the radial direction, from the winding core. Each of the first gripper and the second gripper includes a pair of rollers to interpose and grip the winding. At least one of the first gripper or the second gripper is rotatable about the central axis.
