This presser foot floating system is able to feed even light weight fabrics such as ladies' panties. The Presser Foot Spring Plate is efficient for sewing stretchable materials and the lap portions of material.  The lap width of the fabric edge also adjusts easily.

The tip shape of the Lap Former has been changed to stabilize the lap of materials better than before.  The Lap Former also makes it possible to anticipate the cut length, thereby avoiding the curling of the fabric edge.
