ABSTRACT:
A device for forming double chain stitches in a sewing machine having independent thread sources for its needle and looper. The device includes a driving apparatus for causing travel of the looper solely in a rectilinear pathway in front of the needle and is effective in taking a loop of thread from the needle and to form a triangle of threads into which the needle will descend to effect completion of a stitch as the looper returns to its starting position.
