The position of the feed can be
checked during sewing by means
of the encoder-controlled X-Y drive
stepping motor. This remarkably
improves accuracy of the feed. As a
result, deformation of a sewing
pattern which is likely to occur
when sewing at a high speed or
sewing a heavy-weight material is
significantly reduced.

The frame (needle bar unit and thread take-up unit) is lubricated with grease, and the hook
is fed with a minute quantity of oil from the oil tank. JUKI's advanced dry technology, which
is utilized in a number of our sewing machine models, protects your products from being
stained with oil.

To support the sewing of multi-layered parts of materials, the lower dead point height of the
intermediate presser can be changed steplessly during sewing (standard: 0~3.5mm;
maximum: 0~7.0mm). The intermediate presser will now be able to clamp the material
without fail, thereby preventing troubles in sewing, such as stitch skipping and thread
breakage. Furthermore, flaws on the sewing product are prevented by maintaining the
intermediate height as desired according to the material thickness. (The intermediate
presser stroke is adjustable between 0 and 10mm.)
New programmable
intermediate presser
The intermediate presser goes up and comes down according
to the material thickness.
The height of the intermediate presser is constant.

Market-proven active tension has been introduced
to the needle thread tension controller. With the
active tension, pinpoint changes in the needle
thread tension during sewing are enabled.
The needle thread tension, therefore, can be set in
conjunction with the material thickness and can be
corrected according to the direction of sewing on a
stitch-by-stitch basis through the operation panel.
Since the needle thread tension is reproducible,
supporting a broader range of sewing conditions,
the time required for setup changing upon process
changeover can be reduced.

Double-stepped stroke feeding frame
The feeding frame can be lowered in two steps. It is
very convenient for finely positioning the material
on the sewing machine. The stopping height of the
feeding frame can be set as desired with ease.
◎
Two different types of feeding frames
The feeding frame comes in two different types; the
monolithic feeding frame and the separately-driven
feeding frame. The separately-driven feeding frame
enables easy placement of the sewing material on
the machine since its right and left frame parts can
be operated separately. Both the amount of lift and
the ascending/descending speed of the feeding
frame can be adjusted differently for the right and
left parts of the frame.

★
The double-stepped stroke feeding frame is provided as standard for all
models under the AMS-210EN Series and the AMS-221EN/L Series.
★
The picture shows the sewing machine with a separately-driven
feeding frame.
The separately-driven feeding frame can be selected only for the
AMS-210EN/L1306 and AMS-221EN/L2516.
In order to produce beautiful seams,
new functions have been added.
