Description
It is supplied as complete set (machine, servo/clutch motor and table stand). Installation service not included. The MF-7900 Series is a newly developed coverstitch machine provided with lots of mechanisms for improving the seam quality such as the new feed mechanism, and differential-feed micro-adjustment mechanism. Machine is provided as standard with a looper thread twining prevention mechanism for improved maintenance. 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. The front cover is trimmed to allow operators to bring their hands closer near the needle entry area, thereby increasing work efficiency in the covering process, etc. The feed locus can be adjusted externally. The feed locus is now adjustable in terms of the vertical direction and horizontal direction, thereby improving responsiveness to sewing materials.
Elastic material or delicate material can be sewn with the presser foot kept slightly raised. 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. In the case of looper thread breakage, the looper thread twining prevention mechanism is activated to trim the looper thread before the thread twines on the looper thread cam. The looper thread twining prevention mechanism prevents the looper thread from twining on the looper thread cam. The externally-mounted looper thread cam promises improved maintainability. The commercially-available components (presser foot, throat plate and needle clamp) are now applicable and easily obtainable.
