<p>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 of 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 of the diameter of a wire rod (520). As a result, an advancin-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. <IMAGE></p> |
