ABSTRACT:
A sewing machine including a sewing machine upper portion with a frame, a needle rod and a sewing foot rod, which rods are guided in the frame for back and forth movement parallel to one another, a rack connected with each of the rods and which racks are driven by separate pinions driven by separate electric motors. These motors and possibly other motors for positioning other parts of the sewing machine are separately controlled independently of one another by a program controlled control unit so that the movement of needle road and of the sewing foot rod can be independently program controlled during a sewing procedure.
