1-needle, Lockstitch Machine for Leather and Heavy Materials

This is a newly designed JUKI's unique lockstitch machine. The machine is able to sew at a pitch as long as 7mm for both normal and reverse feed directions.
With the adoption of a feed mechanism and thread takeup lever, the machine achieves increased efficiency of feed and well-tensed stitches. It is a basic lockstitch machine suited for sewing leather or heavy materials such as bags, pouches and purses.

Product features

  • Increased productivity

    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.

  • The machine has easy-to-operate functions to achieve improved operability

    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.

Basic performance

  • Standard with attachment mounting seats

    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.

  • Standard with a feed eccentric pin

    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 maximum stitch length is 7mm

    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.
