Machine for Extra Heavy-weight Materials
An
advanced full-featured machine that
is ideally suited to the sewing of extra
heavy-weight materials.
The machine incorporates a mechanism
and parts that are optimum for the sewing
of extra heavy-weight materials, such
as an extra high-lift type upper looper,
tractor foot and coarse type feed dog.
It demonstrates an excellent performance
ability in the sewing of various kinds
of heavy-weight materials such as jeans,
raised fabric materials, mats and carpets. |
|
|
Features
| 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. |
|
Needle
thread heat remover and needle cooler prevent
stitching troubles during times of high-speed
sewing, thereby contributing to upgraded seam
quality. |
| |
|
|
| 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. |
|
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. |
