Juki MF-7900 Newly Developed Coverstitch Juki Industrial Sewing Machine High-speed, Cylinder-bed, Top & Bottom Coverstitch Machine The Juki MF-7900 series is a newly developed cover stitch machine provided with lots of mechanisms for improving the seam quality: Thanks to the new feed mechanism, many different types of sewing are achieved and responsiveness to sewing materials is improved. 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. 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. Simplified maintenance mechanism The looper thread twining prevention mechanism has been improved and is provided as standard for the sewing machine. 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 externally mounted looper thread cam promises improved maintainability. Commercially available gauge components are applicable with no additional work. As a result of the commonality of components, commercially available components (presser foot, throat plate and needle clamp) are now applicable and easily obtainable.
