ABSTRACT:
A tape winder includes: a hub, around which a tape is wound overlappingly and which forms a tape roll on the hub; a first guide roller, defining the position of feeding of the tape into the tape roll being formed on the hub while pressing an outer peripheral surface of the tape roll; and a moving mechanism, moving the first guide roller away from the rotation axis of the hub as the tape roll increases in diameter. A rotation axis of the first guide roller is positioned along a normal to a reference surface and the rotation axis of the hub intersects the rotation axis of the first guide roller at an angle θ. The tape is processed to provide winding curl to the tape through winding the tape on a tapered hub with inclination and a heat treatment to fix the winding curl.
