Juki DDL-8700L Lockstitch (Long Stitch)
1-Needle, Long Stitch Type, Industrial Lockstitch Sewing Machine for Leather and Heavy-Weight Materials
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 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 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.
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.
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 multilayered 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 multilayered portions of the material with no stitch gathering or thread breakage.
Newly designed machine head that was developed in pursuit of beauty
The optimum-balance and highly rigid machine head were
created using the latest 3D-CAD design technology.
Thanks to its low vibration and low noise feature, the
machine head provides the operator with a comfortable
work environment. In addition, the distance from the
machine arm to the needle on the front of the machine
head is sufficiently wide to allow easy handling of the
The machine inherits the desirable features, such as highspeed stitching performance 5,500rpm, extreme stitching
performance, ease of operation, and reliability, from the
highly evaluated previous JUKI lockstitch machines.
Sewing mechanism that demonstrates outstanding responsiveness to materials to be sewn.
By thoroughly investigating and modifying the sewing
mechanisms in order to achieve low-tension sewing, the
machine flexibly responds to various kinds of materials
and produces beautiful seams of consistent quality.
The machine has easy-to-operate functions to achieve improved operability.
By providing a presser foot with a higher lift(13mm), a lighttouch stitch dial, a throat plate with marker grooves that can be
used as guide for seam allowance, and other easy-to-operate
functions, the burden on the operator is lightened, and
productivity is further increased.
Maintainability was improved.
Enhanced maintainability is ensured by the improved machine head, such as incorporation of an eccentric pin that is used to adjust the feed dog.
In addition, the machine is provided with a mounting seat for attachment to improve workability whilea replacing the attachment and increasing the durability of the machine bed surface.
