Features
| The
hook driving shaft offset mechanism
assures trouble-free and consistent
zigzag stitching. |
The machine is equipped with a
hook-driving shaft-offset mechanism
which places the hook-rotating
shaft off-center from the center
of zigzag stroke of the needle.
This mechanism allows the blade
point of the hook to catch the
needle thread every time regardless
of the needle throwing direction.
As a result, the machine is immune
to sewing troubles such as stitch
skipping and thread breakage,
annoyances likely to occur with
the conventional machine, especially
when the needle throws to the
right. |
| |
 |
|
 |
| The
market-proven hook and thread
take-up lever enables sewing with
upgraded consistency with a lower
tension applied to the thread. |
With its market-proven hook and
thread take-up lever, the machine
produces high-quality, uniform
seams even when sewing at extremely
low thread tensions.
In addition, these new components
prevent stitch skipping and thread
breakage during sewing and offer
dramatically improved responsiveness
to thread changing. The machine
uses a wide range of thread types
such as synthetic thread, spun
thread, and cotton thread. |
| |
 |
|
| Greater
durability is secured by preventing
the hook from heating up when
the machine is running at high
speeds. |
| |
The inner hook is finished with
titanium to keep it from becoming
hot. The machine requires only
a very small quantity of oil.
This prevents oil stains on the
material and the improves durability
of the hook. In addition, the
hook configuration is carefully
designed to avoid needle breakage. |
|
|
 |
| The
highly reliable machine head is
structured to reduce operating
noise and prevent oil leakage.
|
|
The
shape of the machine frame is
designed to reduce vibration and
noise during sewing. By applying
three safeguards in the machine's
design, oil leakage is completely
eliminated.
The shape of the machine arm is
designed to prevent oil from gathering,
the direct oil-circulation method
is adopted to circulate the oil
directly from the oil sight window
to the oil pan, and a high-quality
packing is incorporated. In addition,
a bobbin thread winder is built
in at a position that permits
easy bobbin winding. |
|
|
| The
machine ensures easy adjustment
of zigzag width and feed pitch. |
| A
special dial with a built-in lever
for adjusting zigzag width is
adopted for easier handling. The
machine is also provided with
a lever for changing the needle-throwing
position that makes it convenient
to set the sewing position from
the material edge. This enables
the operator to minutely adjust
the needle-throwing position without
re-adjusting the positions of
other components such as the guides
and binders. In addition, the
machine is provided with a denser
stitching mechanism for fastening
stitches. |
