The innovated thread-taking-up mechanism of such machinery enlarges the application scope of the machine so that sewing materials of different thickness can be sewn, including the adhesive compound materials. Stitches are beautiful and stable. The transmission mechanism adopts the automatic oil-servicing mode by the oil pump, the machine can get sufficient lubrication. The operation is stable and reliable. The utilization of high-precision imported bevel wheels and vital spare parts has greatly reduced the noise and improved the precision and service life of the machine. The maximum sewing speed has reached 5000 R. P. M. Major spare parts on the rotary parts of the machine head have applied special-type quality steel, so they are endurable and can meet the demand from the long-time high-speed rotation. The stitches produced by such machinery are beautiful. They are applicable to the sewing of garments, including underwear, shirts, suits and jeans.
