MO-6800S SERIES
This advanced overlock / safety stitch machine is
easier to use and promises superior cost effectiveness.
The 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 / safety stitch
machine is easier to use and promises superior cost-effectiveness.
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 which 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.
For runstitch / MO-6816S-FF6-30H
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.
