ABSTRACT:
A winding apparatus suitable for a toroidal coil. Arms swivel around a core and move up and down. Movable bodies having rollers on which the wire is wound, are mounted on the arms and move along the arms. A tensioning mechanism pulls the movable bodies away from the core while adjusting the pulling forces separately. Chucks pass the wire through the center hole of the core from an entrance to an exit. One chuck holds the wire near a tip which has passed the center hole and brings the tip back to the entrance by crossing the moving path of rollers and moving around the core.
