Juki MF-7723,3-Needle,High Speed,Flatbed,Top and
Bottom Coverstitch Hem Machine,w/ Differential


The Juki MF-7700 series state of the art machine has been designed through a thorough ongoing
study of seam quality. The machine is provided as standard with a great diversity of easily adjusted
features to increase applicable types of sewing products. The well-balanced design of the machine
achieves low-vibration and low-noise operation even under high-speed mode.

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
