1-needle,
Unison-feed, Lockstitch Machine with Large Hook
|
| DNU-1541S(with
safety mechanism) |
 |
With
its reliable feed and consistent seam quality,
the machine responds outstandingly to the sewing of
heavy materials. |
|
|
|
|
Excellent
sewing capabilities and feed performance. |
 |
With its larger needle bar stroke, higher
presser foot lift, and newly adopted double-tension
mechanism, the machine offers excellent sewing
capabilities and responsiveness.
|
|
The alternating vertical movements of the
walking foot and presser foot are as large as 6.5mm. In
addition, the ratio between alternating vertical
movements of the walking foot and presser foot remains
unchanged even when the material thickness changes.
Thanks to this feature and the adoption of a new method
of rectangular feed that prevents needle from fraying,
the machine sews multi-layered parts of a material with
consistent stitching pitch while preventing stitch
gathering. |
 |
 |
| • |
Compared with the elliptical feed, the
rectangular feed helps reduce gathered stitches. |
|
| • |
The ratio of alternate vertical movement
remains unchanged even when the material
thickness changes. |
|
|
|
 |
| • |
Higher lift of the presser foot |
|
 |
| • |
The maximum alternating vertical movement is
6.5mm. |
|
|
|
High-speed
performance increases productivity. |
|
The machine delivers increased
productivity at sewing speeds as high as 2,500rpm
 |
|
|
|
Safety
mechanism.
(DNU-1541S) |
|
When the thread is caught in the hook or
any other sewing trouble occurs, the safety mechanism
will automatically operate to prevent the machine from
being damaged.
 |
|
|
Excellent
operability and maintainability. |
|
The stitch length can be easily selected
by the stitch dial.
The machine's enhanced operability features include a
clear view of the area around the needle, placement of
the bobbin thread winder on the front face of the
machine arm, and a large handwheel( 160mm).
|
|
A knee-lifter mechanism is built in the
bed. This reduces the pressure required to operate the
knee-lifter and facilitates setup.
|
|
The machine’s full-open-type top design
makes adjusting works easier.
|
|
The machine comes with a lubricating
mechanism that uses a centralized oil wick. This
substantially reduces the time and trouble required for
oiling the machine. (Hook : automatic.)
|
|
A walking foot mechanism is built into
the machine arm to prevent oil from scattering |
