MF7700

UNIVERSAL TYPE (Basic Type):
This machine can be used for the hemming process of the sleeves and bottoms of T-shirts and for the covering process for sportswear and knitwear. It is not a specific-purpose model, but a basic one which can be used for a broader range of processes independently.


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 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 provided with various functions:

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 diffential-feed ratio is constant, requiring no additional adjustment, even when the stitch length is changed.

Micro-lifter mechanism

The micro-lifter keeps the presser foot in a slightly raised position during sewing to help prevent problems such as slippage and deformation, or damages that can easily occur when sewing elastinc materials.

Needle bar stroke conversion mechanism

The needle bar stroke can be increased by changing the position of the eccentric pin to smoothly sew heavy-weight materials. The troublesome replacement of parts, which is conventionally associated with needle-bar-stroke changing work, is no longer required.

Feed dog inclination adjustment machanism

Adjustment of the feed dog inclination can be carried out from outside with ease. The feed dog inclination adjustment mechanism works effectively to secure the material being sewn in place with increased reliability and thereby preventing uneven material feed and puckering.

Looper thread twining prevention mechanism

The looper thread cam comes provided with a thread twining prevention mechanism. Even if the thread twines around the looper thread cam, the cam can be easily detached for removal of the thread.

The machine operates with reduced vibration and noise, promising comfortable sewing.

The well-balanced design of the machine achieves low-vibration and low-noise operation even under the high-speed mode. This enables the operator to concentrate on sewing work in a more comfortable environment.
