High-speed, Variable Top-feed, Overlock/Safety Stitch Machine
MOR-3900 SERIES
Many different kinds of subclass models have been prepared for
materials with different thickness each of which has the presser foot
pressure and the height and vertical stroke of the top-feed dog
optimally set in accordance with the intended material thickness.
The machine also adopts a newly developed feed mechanism that
provides a larger area where the locus of movement of the top-feed
dog horizontally synchronizes the bottom-feed dog, thus achieving
the secure feed of the material without damaging it.
The feed mechanism softly holds light-weight materials and securely
catches heavy-weight materials for smooth feeding.
By setting the fulcrum position of the locus of the top-feed near you,
the rake-in always starts at a constant position and the force to catch
the material is increased.
performance when feeding heavy-weight materials such as jeans.
The machine for ruffling is capable of making beautiful and uniform
ruffles.
