Abstract
A two-thread lock-stitch sewing machine with a thread cutter comprises a shaft which is parallel to the vertical axis of a shuttle and has a lever arm with a thread pulling knife disposed on it. The bobbin case in the shuttle has a holding finger which is directed toward a stitch hole and is held between two cams that are arranged on a rib. Formed between the cams and the workpiece bearing plate is an interspace which the lever arm passes through, together with the thread pulling knife projecting into a space between the motion travel of the sewing needle and the cams so that a thread cutting operation is enabled to be performed with very short thread tail pieces remaining on the lower side of the workpiece. The thread cutting operation excels by simple design and reliable operation.
