ABSTRACT:
An apparatus for winding elongated wire pieces around frame-like cores of a workpiece comprises a workpiece holder, mounted on a base so as to be movable about an axis perpendicular to an operation surface, for holding a workpiece with its frame-like cores extending therefrom, a wire piece having a first end portion fixed by the holder and a second end portion extending toward a second end face side being inserted in each core of the workpiece held by the holder, a tension means, movable in directions to move close to and away from the workpiece holder, for holding the second end portion of the wire piece, a pin fixed to the workpiece holder so as to be movable between an inoperative position at which the pin is not in contact with the wire piece and an operative position at which the pin deflects the wire piece in one direction, the operative position being defined such that contact of a wire piece portion between the workpiece holder and the tension means with the frame-like core being prevented when the workpiece holder is rotated about its rotational axis, and a guide means for guiding a wire piece portion between the tension means and the pin when the pin returns to the inoperative position after the pin is rotated together with the workpiece holder to a position at which the core is located at a position opposite to the home position.
