Abstract
A mechanism and method for forming a facing seam at a relatively high rate that will insure that the cover thread is properly interwoven between each stitch of two parallel rows of stitches. The facing seam is formed by two needles and cooperating loopers for forming two parallel rows of stitches that are joined by a cover thread that lies on the upper surface of the work piece. The cover thread is controlled by a conventional spreader and a cover thread assist member. The cover thread assist member is formed from a lightweight hardened wire that is fixed to a mid portion of the conventional spreader.
