ABSTRACT:
A thread chain is prevented from hanging at an inner chain-off finger when it is turned back or rotated to the operator's side for holding and cutting. A needle thread, positioned at the front side of a lower looper, is guided by a needle thread restricting device, and a needle thread positioned on the back side of a lower looper is prevented from being hung on an inner chain-off finger by a thread chain guiding device provided at a throat plate so that enfolding back and tacking of the thread chain into the fabric material is performed well.
