Empty heading

Includes Fully Assembled Table and Servo Motor - Used to be MF-7823

The machine performs sewing that matches a broader range of sewing items.

The 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.

Features

Fully Assembled Table & Servo Motor

No Looper Thread Twining

The newly-developed metal cover for the looper thread cam unit also covers the rotating part of the looper thread cam shaft, thereby preventing the looper thread from twining around the looper thread cam shaft.

Needle Bar Stroke Conversion Mechanism

By changing over the needle bar stroke, penetrating force of the needle as well as thread tension to fit heavy-weight materials (fleece, blankets) can be obtained. The needle bar stroke can be changed by adjusting the eccentric pin. (Changing of parts is not required. Factory-set at the time of delivery: 31mm; for sewing heavy-weight materials: 33mm)

Micro-Lifter Mechanism

Elastic material or delicate material can be sewn with the presser foot kept slightly raised. This effectively helps reduce the degree of slippage, warpage and damage of the material.

Stitch Type Change Over

It is now possible to change over the stitch type, such as elastic soft-seams for inner wear and high-quality well-tensed seams for outer wear. The stitch type can be changed over (soft-seams/well-tensed seams) simply by changing the thread path.

Differential-feed Micro-adjustment Mechanism

It is possible to finely adjust the differential feed amount to a best-suited value for the material to be used. The differential feed ratio is constant even if the stitch length is changed
