This machine adopts link-typed feeding mechanism, meedle bar thread tacking up, and looper thread catching to produce two lines of chainstitch, which is firm and elastic, suitable for lapping seam and decorative seam on garment, underwear, bedding articles and leather goods. There are five different gauges available for selection.

By changing fixed needle protection mechanism into moveable needle protection mechanism it can prevent needle breaking and stitch skipping effectively in the motion of the thread hooking, and make stitching more beautiful.The main running parts of the machine head are all made of the high quality steel, ensuring high speed operation for a long time.
