ABSTRACT:
A needleplate for a two-needle sewing machine of the type for simultaneously forming a straight stitch chain and an over cast stitch chain. The plate is provided with guide surfaces which interconnect the needle holes in the plate and a device for increasing the quantity of thread normally used by the looper associated with the needle for forming the straight stitch chain. At the completion of a sewing cycle the combination of the guide surfaces and excess looper thread permit the straight stitch chains to be moved toward and in alignment with the overcast stitch chain so that they will be incorporated together in the initial stitches formed in the following workpiece.
