3 Needle 4 Thread Top Bottom CoverHem Stitch Machine & Stand with servo motor
Seams can be adjusted depending on the application or material by changing the thread path or adjusting the thread tension controller, to produce soft and low-tensed seams for inner wear or to produce high-grade well-tensed seams for outer wear.
The optimized thread take-up mechanism and top covering thread path route contribute to an increased stability of top covering stitches. In addition, the machine is capable of performing sewing with a low tension applied to the thread to offer improved responsiveness to the sewing thread.
A differential-feed adjustment mechanism with a micro-adjustment mechanism to provide a constant differential-feed ratio. The differential-feed amount can be easily adjusted to the best suited value for the material to be used.
A feed dog inclination adjustment mechanism to work effectively at securing the material being sewn in place with increased reliability and thereby preventing uneven material feed and puckering.
A micro-lifter to keep the presser foot in a slightly raised position during sewing to prevent slippage and deformation.
