ABSTRACT:
An automatic sewing machine provided with a memory for storing stitch instructions directing a relative position between a vertically reciprocated needle and a work piece and a speed control means for controlling the machine's drive motor at a suitable speed for each particular sewing operation carried out according to the stitch instructions. To determine the maximum permissible speed suitable to the variation of the relative position for each stitch, all of the stitch instructions in the memory are checked by a central processing unit before starting each sewing operation. The unit provides a control signal concerning the maximum permissible speed to a speed control means so that the driving speed of the drive motor is limited to no more than the maximum permissible speed.
