ABSTRACT:
A multi-needle chain-stitch seam is secured against unravelling and loosening by the following steps: A beginning region (A) of the seam is formed with short needle thread loops (6,7) an intermediate region (B) of the seam is formed with long needle thread loops (9) and an end region (C) is again formed with short needle thread loops (6,7).
An adjusting member (67) actuated in a controlled manner on a sewing unit influences the formation of the stitches of the seam.
