1. An apparatus for manufacturing a taped insulated conductor including a wire material feeder for feeding a wire material, a tape winder for winding a tape body around the wire material fed from the wire material feeder, and a receiving device for receiving the wire material around which the tape body is wound by the tape winder,
the tape winder comprising:
a tape pad fixing part for fixing a tape pad around which the tape body is wound;
a tape feed part having a first drive source including a servo motor for rotatingly driving the tape pad fixing part, so that a rotating shaft torque is controlled to a prescribed torque, thereby setting a delivery tension of the tape body to a prescribed value;
a tape winding flyer rotatably mounted to an outside of the tape feed part and having a plurality of tension control rolls for controlling a tension of the tape; and
a tape winding part having a second drive source including a servo motor for controlling a rotation of the tape winding flyer to the prescribed number of rotations;
wherein the tape body is fed from the tape pad to the tape winding flyer without a tension with the rotation having the rotating shaft torque controlled by the first drive source; the tape body fed to the tape winding flyer is wound around the wire material in a state in which a tension of the tape body is set to a specified value by the rotation made by the second drive source dependent on a contact area with which the tape body is twined around each of the tension control rolls.
