Juki MO-6814S

High-speed Industrial 4 Thread Overlock Stitch Serger


This advanced overlock machine is easier to use and promises superior cost effectiveness. The Juki MO-6800S Series responds to various kinds of sewing materials and processes, producing delicate and beautiful soft-to-the-touch seams while further reducing operating noise as well as increasing durability. This advanced overlock machine is easier to use and promises superior cost-effectiveness as well as the responsiveness from light- to heavy-weight materials with a lower applied tension. The machine is provided with functions which contribute to easier operation. The differential-feed micro-adjustment mechanism, external increasing of the differential feed ratio and the main feed dog height can all be adjustable on the front face of the sewing machine with a screwdriver. The machine is provided as standard with functions which enable easy and best-suited adjustments according to the material to be used. The machine achieves beautifully finished seams of improved quality even when run at a high speed. The machine is widely applicable to the sewing of light- to heavy-weight materials. Since the machine is provided with a needle thread take-up mechanism and a looper thread take-up lever, it ensures high-quality, well-tensed, and soft seams with a beautiful texture that flexibly correspond to the elasticity of the materials even when run at speeds as high as 7,000 sti/min. In addition, the machine has a wider and brighter needle entry and provides improved responsiveness to the materials, thereby helping the operator use the machine more easily. The optimally balanced design of the machine reduces both operating noise and vibration, contributing to more comfortable sewing work.
