Abstract
A shuttle body 3 having aloop seizing beak 10 for seizing a needle thread 9 is rotatably attached to a shuttle race body 2, pressed by a driver 4, and continuously rotated in a rotation direction B in synchronization with vertical motion of a needle 8. A bobbin case 5 in which a bobbin thread 12 wound around a bobbin 5 is accommodated is attached to the shuttle body 3. Under a state where the bobbin thread 12 is pulled out from the bobbin case 5, the shuttle body 3 is rotated, the needle thread 9 is seized by the loop seizing beak 10, the loop of the needle thread 9 is expanded along the outer face of the shuttle body 3, the loop of the needle thread 9 is passed over the shuttle body 3 and the bobbin case 5 so that the shuttle body 3 and the bobbin case 5 are passed through the loop of the needle thread 9, whereby the needle thread 9 is wound around the bobbin thread 12 and a stitch can be formed.
