The machine head was remodeled to achieve an
optimumly balanced and highly rigid machine head
frame. With its reduced vibration and noise and easy
operation of the feed lever at the time of reverse
stitching, the machine promises to make sewing work
more comfortable.
The wider distance from the machine arm to the needle
on the front of the machine head, smoothened design
of the machine head, larger needle bar stroke (35 mm),
and higher lift of the presser foot (13 mm) enable easy
handling of heavy material. In addition, the machine is
equipped with a handwheel that is larger than normal
for easy turning.
The stitch length can be
adjusted to a maximum of
7mm(both in normal feed
and reverse feed directions).
The highly reliable and
durable feed mechanism
ensures accurate and
consistent stitch length with
no errors in the case of long
stitching pitches.
By adopting the locus best suited to the sewing of leather and heavy materials, the
machine smoothly feeds heavy materials without stitch gathering even on multi-
layered portions. The machine also uses a fluorocarbon resin presser foot that offers
sharp-curve sewing capability to prevent from scratch on the material.
The hook, gauge, and thread take-up lever are all exclusively designed for the
DDL-8700L to enhance its ability to produce beautiful well-tensed seams. The design
ensures consistent sewing in difficult processes such as the sewing of heavy multi-
layered portions of the material with no stitch gathering or thread breakage.
●To order, please contact your nearest JUKI distributer.
The machine has an attachment
mounting seat. This make it easier
to replace attachments and
increases the durability of the
machine bed.
Furthermore, the machine is
equipped with a feed eccentric pin.
This enables easy adjustment of
the feed dog inclination and feed
timing(phase), thereby offering
improved maintainability.
The machine runs at higher sewing speeds than any other
lockstitch machine intended for heavy materials anywhere in
the world, reaching, up to 4,000sti/min for stitch length of less
than 5mm and 3,500sti/min for stitch length of up to 7mm.
The result is dramatically increased productivity.
