Abstract of the Disclosure In order to convert a standard manually controlled bar tacker type sewing machine to automatic numerical control an assembly to constructed which consists of a stepping motor drive system operatively connected to the work clamp positioning levers through gear sectors mounted on pivot arms. In this manner rotation of the stepping motor? causes movement of the work clamp along two axes similar to the motion caused by a style caps. The style cam is therefore eliminated. Collateral functions such as nipping and thread cutting are initiated by the knife cam which is driven through a clutch by the cam shaft. In order to remove the restrictions caused by gear ratio and cam size and shape, the knife cam is engaged only for the first and last few stitches of the tack design. The control system, therefore, initiates and times the positioning of the work clamp, starting and stopping of the machine and engagement and disengagement of the knife cam.
