Abstract
A sewing machine carries a sewing needle which in turn carries a thread through a stitching aperture of a throat plate beneath which is located a gripper carried by a gripper shaft. The gripper is defined by a gripper neck, a gripper hook and a gripper knee joining the gripper hook and the gripper neck. Located adjacent the gripper bend is a thread-cutting blade. A cam, link and linkage system is provided for selectively driving the gripper shaft to selectively (a) move the gripper (7) a predetermined distance through which the cutting blade is inoperative and (b) move the gripper a further distance beyond the predetermined distance through which the cutting blade is operative to cut-off the thread. A stop boss is also provided adjacent the gripper bend to prevent the thread from being cut during motion of the gripper the predetermined distance.
