Abstract

PURPOSE:To enable the bobbin exchange work and improve the working efficiency by rotating a grip mechanism once in the opposite direction to the rotating direction of the bobbin. CONSTITUTION:In the exchange of a bobbin 3, a grip mechanism 33 is rotated in the opposite direction to the rotating direction of the bobbin 3 by a rotating mechanism to make the grip mechanism 33 hold a wire rod W situated between a traverse mechanism 5 and the bobbin 5 in the course of the rotation, and by rotating the grip mechanism 33 as it remains holding the wire rod W, the wire rod W between the grip mechanism 33 and the bobbin 3 is pulled and cut off. The bobbin 3 is taken out in this state, and the wire rod W is drawn from the traverse mechanism 5 side by the further rotation and placed in a gap formed between the one side surface of the bobbin 3 and a wire press body 30. When a new bobbin 3 is held by a driving shaft by means of a holding mechanism, the wire rod W is held between one side surface of the bobbin 3 and the wire press body 30.
