Abstract
A sewing machine in which the start and stop of a main shaft is controlled by a cam mechanism through a motion control mechanism at the sewing cycle corresponding to a predetermined number of stitches. The working position of a work holder is controlled by positional data in original instructions stored in a memory. Additional instruction corresponding to the number of stitches to reach the next stop time point controlled by the cam mechanism is prepared for back-tacking, unless the number of stitches corresponding to the original instructions are equal to an integral multiple of the predetermined number of stitches.
