Abstract
A sewing machine with a presettable counter for sewing a predetermined number of stitches to the end of a stitch seam. According to the invention the counter is provided with a correction unit responsive to at least two sectors of a rotary machine member, each revolution of which corresponds to the sewing of a stitch of normal length. A sensor is responsive to the different sectors and, upon detection of one of these sectors, produces a signal which an evaluating unit can pass to a count resetting unit to set back the stitch counter by one stitch unit. As a consequence, the overrun or underrun of the stitch seam is at most one half of the normal length of a stitch.
