ABSTRACT:
A sewing machine adapted for moving a workpiece in a downstream direction for sewing a seam therein, and for automatically terminating the seam at a predetermined point a selected distance from a trailing edge of the workpiece. An edge sensor on a base is located a predetermined distance upstream of the sewing point for sensing the downstream passage of the trailing edge, and generating edge sensing signals in response thereto. A stroke sensor on the base senses the length of the strokes of the feed dog and generates stroke length signals which are indicative of the stroke length and of the length of the stitches. A stopping device is provided on the base for being actuated to engage the workpiece to stop its movement when the sewing needle is at the predetermined point for terminating the seam; and a control system receives the edge sensing signals and the stroke length signals, determines therefrom a time when the sewing needle will be at the predetermined point, and generates a stopping signal for actuating the stopping device at that time.
