This machine adopts compound feed mechanism with
synchronous top, bottom and needle feed and the
max amount of alternating presser foot lifter reaches
7 mm, which guarantees the high sewing quality of
different materials. Besides, it adopts the large
auto-lubricating horizontal rotating hook, 4-link
thread take-up lever and timing belt, which assures
its lower noise and high speed.
This machine is widely used in manufacturing
suitcase, tents, cushions, lenther products, clothes
bamboo matting, etc.
