ABSTRACT:
A sewing unit with a thread-guiding needle, with a lock stitch hook with a thread reserve, with a fabric holder that can be moved in any direction relative to the needle axis, and with a fabric presser foot with a needle passage opening, which can be placed on the fabric in cycle with the movement of the needle. Loop or twist stitches are formed in an area of the possible directions of movement of the fabric holder. To pull these stitches reliably into the fabric, the needle passage opening is asymmetrically widened beginning from the site of the needle passage, namely, elliptically beginning from a part semi-circularly surrounding the site of the needle passage in one design, and angularly with an arched limiting edge connecting the legs of the angle in another design.
