摘要 A traverse shaft section 609 shifts in response to the rotation of a bobbin rotating section 604 with a predetermined winding pitch P1 equivalent to two to 10 times the diameter of a wire rod 520. With this shift movement of traverse shift section 609, wire rod 520 extracted from a winding nozzle section 610 shifting together with traverse shaft section 609 is wound spirally along a slant surface 530 formed by a first winding section 541 at the winding pitch P1 equivalent to two to 10 times the diameter of a wire rod 520. As a result, an advancing-side wire rod 520a and a reversing-side wire rod 520b cross over each other at opposing inclinations. Hence, it becomes possible to prevent the reversing-side wire rod 520b, when wound on the advancing-side wire rod 520a, from pulling and dislocating the advancing-side wire rod 520a from its regular winding position, thereby eliminating undesirable winding collapse.
