ABSTRACT:
A chaining thread sew-in device for sewing a chaining thread produced consecutively in the seams of a preceding cloth and in the seams of a next cloth when forming seams by an overlock sewing machine. The free end of the chaining thread (Ch) cut off from the preceding cloth is inserted into an insertion hole (H) opening on a sewing machine working face (1a), and the inserted chaining thread (Ch) is pinched beneath the sewing machine working face (1a), so that the chaining thread to be sewn into the seams of the next cloth is set at specified position on the sewing machine working face (1a). The chaining thread set at a specified position is moved to a cutter (40) installed side of the machine by driving a sub-pinching plate (72, 272), and is cut off from the pinched part by this cutter (40).
