Return - MF-7700 series

High-speed, Flat-bed, Top and Bottom Coverstitch Machine

DEBUT! The MF-7700 series
state-of-the-art machine that has been designed through a thorough ongoing study of seam quality

Since the seam tension may be easily increased or decreased, the machine can be used for a broader range of applications

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.

Optimization of the thread take-up mechanism and top covering thread path route

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.

The machine comes with a variety of features to increase applicable types of sewing products

The machine is provided as standard with a great diversity of features, such as a differential-feed adjustment mechanism with a micro-adjustment mechanism, a feed dog inclination adjustment mechanism, a micro-lifter and a needle bar stroke conversion mechanism. The machine can therefore be quickly adjusted to respond to various materials and processes, thus increasing the applicable types of sewing products.

Differential-feed micro-adjustment mechanism

The differential-feed amount can be easily adjusted to the best suited value for the material to be used. Since the front and rear feed dogs are synchronized, the differential- feed ratio is constant, requiring no additional adjustment, even when the stitch length is changed.
