●The machine securely clamps the material
at the beginning of sewing as well as
smoothly sewing multi-layered parts of
the material to facilitate the sewing of
extra heavy-weight materials.
●The MO-6900J Series comes with a newly-
developed feed mechanism that moves
the top and bottom feeds separately.
With its improved feeding capacity and
stronger cloth-biting force, the feed
mechanism prevents uneven material
feed when sewing extra heavy-weight
materials.
●The machine incorporates mechanisms
that are both durable and reliable, such
as the needle bar mechanism, utilyzing
the upper and lower bushings, a
cartridge type oil filter and cooling fan.
●The machine is equipped as standard
with a micro-lifter that helps reduce
operator fatigue. The micro-lifter is
designed to achieve optimum balance,
not only reducing noise and vibration
but also ensuring comfortable operation.
●Needle thread heat remover and needle
cooler prevent stitching troubles during
times of high-speed sewing, thereby
contributing to upgraded seam quality.
●The machine comes standard with
various adjusting mechanisms, such as
a micro-adjusting mechanism, all of
which can be easily adjusted to enable
the machine to perform sewing under
the best-suited conditions for any kind
of material.
