Abstract
A pair of tracks are pivotal and alignable with a stitching station of a sewing machine. Carried on each track is a clip which is normally biased away from the sewing machine but displaceable against the biasing force toward the stitching station. Each clip has a lower jaw swingable between an upper operative position and a lower return position and an upper jaw pivoted on the lower jaw and swingable between an upper open position, a lower operative position, and a third return position. In the return positions both of the jaws are below the plane of the support table adjacent the sewing machine. The trailing edge of a workpiece is clipped in one clip and the leading edge of the workpiece is fitted to the sewing station. As the clip approaches the sewing station it first automatically opens, then is automatically swung into the return position so that a workpiece whose trailing edge is held in the other clip can then pass over the returning clip to the sewing station.
