High-quality stitches which match the
Soft-to-the-touch stitches help create a
as if sitting on a sofa
The PLC Series machines have been finished with one-rank upgraded performance,
laying importance on stitching.
Increased efficiency of feed
The alternating vertical movement mechanism prevents irregular stitches
The machine comes with JUKI's unique
alternating vertical movement mechanism,
where the presser foot's amount of alternating
vertical movement does not change even when
the material weight changes.
The amount of alternating vertical movement of
the presser foot does not decrease even when
a heavy-weight material is sewn. Therefore, the
efficiency of the walking foot does not
decrease so as to prevent uneven material
feed.
The amount of alternating vertical movement is
adjustable up to 6.5mm according to the
weight of the material or any multi-layered part
of it.

relaxed state of mind,
The PLC-1700 Series machines have substantially been improved in their
overall "efficiency of feed. " The machine smoothly handles large and
heavy-weight materials with an increased efficiency of feed, thereby producing
consistent seams free from irregular stitches (differences in stitch length).
Consistent stitching performance
Conventional machines
Needle
Feed
Needle insertion timing
The "needle" inserts into the fabric
during the returning motion, which is
likely to produce gathered stitches.
PLC Series
Compared with the elliptical-feed,
the rectangular-feed helps reduce
gathered stitches.

Powerful rectangular-feed mechanism
JUKI's unique feed mechanism has been
employed to eliminate stitch gathering, which
is likely to occur with the conventional feed
mechanism (elliptical-feed).
The rectangular-feed locus produces an
increased efficiency of feed with consistency
from the beginning to the end of sewing.
Since the feed dog's amount of lift is small,
material flopping, noise and vibrations can be
reduced.
Dual-tension mechanism
The machine is able to perform sewing with
low-count thread under a higher tension, which
is difficult for the conventional single-tension
method, with ease.
The machine comes with a dual-tension
thread tension system
(two tension posts are used for a single thread).

PLC-1700 Series

L type (thick-thread long-pitch)
The machine performs sewing with consistency with a broader range of needle counts up to #0.
In addition, it achieves the maximum stitch length of 12mm.
A triangular cam has been adopted for the feed rock cam. This
enables consistent sewing with a thread count of up to 0.
The machine comes provided as standard with a handwheel
which is larger than the S type (standard) so as to increase the
material-penetrating force of the needle.
In order to ensure an efficiency of feed (presser foot pressure)
which is larger than that provided by the S type (standard), a
double-coil spring is equipped as standard for the pressure bar
spring.
The maximum stitch length is 12mm for both forward and
reverse feed directions. In addition, the alternating vertical
movement dial is provided as standard.
Excellent operability
The basic performance (specifications) has been dramatically improved
A maximum number of revolutions of
2500sti/min (increased by 25%) is
achieved to increase productivity.
Higher lift
of the presser foot
The presser foot lift is as high as 16mm, allowing the user to
handle the material with ease.
Simple-setting of the amount of
alternating vertical movement
The vertical strokes of the presser foot and walking foot
(alternating vertical movement) can be easily changed using a
large dial mounted on the top surface of the machine head.
In addition the sewing speed is automatically adjusted with the
set value. With this feature, ideal sewing conditions are
maintained at all times.
The machine is able to support a
maximum stitch length of 9mm (12mm
for the L type).
It is now possible to factory-install the
presser foot with a center guide for
2needles at the time of delivery.

Safety mechanism
nstantaneous change-over device for the
alternate vertical movement amount (DL device)
The machine has been provided with a DL device, which
demonstrates its ability in processes for sewing lots of
multilayered parts of material.
The amount of alternating vertical movement is instantly
maximized by turning on the DL switch placed under the arm or
the knee switch.
Even in a situation such that the thread is caught in the hook,
the safety device automatically works to prevent the hook from
breaking. Resetting is possible only with a button.
Thread trimming without fail
The count of thread which can be cut by the thread trimmer is
TEX 50 to 135.
The knife pressure is easily adjustable when the count of
thread is changed.
