Abstract
A sewing machine automatically sews a seam which ends at a desired point. The last n stitches, preferably the last two stitches, are of substantially equal length. A counter counts pulses while the work is being fed to the needle. The machine detects when the trailing edge of the work passes by a predetermined location ahead of the needle. Upon such detection, the contents of the counter are used to calculate the proper stitch pitch for the last two stitches. The stitch pitch is varied as necessary during sewing of the last two stitches in the seam.
