Super-high-speed, Cylinder-bed, Overlock Machine
MO-6900C Series
● The cylinder-bed is bestsuited to the runstitching and blind hemming
of tubular materials.
● Since the machine comes with a needle-thread take-up mechanism as
well as a looper thread take-up mechanism, to enable sewing with a
lower tension applied to the material, it achieves soft-feeling high-
quality seams.
● Since the machine is provided as standard with the bottom feed dog
inclination-adjusting mechanism and the external differential feed-
increasing mechanism, it can be easily adjusted to ideally match the
material being sewn. In addition, the machine is provided as
standard with a micro lifter feature that offers improved
responsiveness to materials, and provides the operator with
upgraded operability. The stitch length can be easily adjusted with
the push-button mounted on the front surface of the sewing
machine.
