Abstract

A method and apparatus for forming a longitudinal row of stitching in a base fabric with a reciprocal needle and cooperating looper, in which the looper is driven through two or more strokes for each stroke of the needle in a stitch cycle. In the preferred form of the invention, the looper points in the opposite direction from the longitudinal direction of movement of the base fabric, for the formation of either loop pile or cut pile stitching. When loop pile is formed, the stitching results in a chain stitch.
