The JUKI MO-6704DA is a high-speed, 1-needle industrial overlock machine designed for professional garment production and general overedge sewing. It produces a U.S. Stitch Type 504, 3-thread overlock stitch, providing a clean, secure edge finish on a wide range of fabrics.

Built for continuous industrial use, the MO-6704DA combines high production speed with smooth feeding and precise stitch formation. Its differential feed can be adjusted to help prevent puckering or stretching and can also be used to create controlled gathering when desired.

Semi-Dry-Head Technology

One of the major advantages of the MO-6700DA series is JUKI's dry-head technology. The needle-bar and upper-looper mechanisms have been redesigned to operate without lubrication, helping reduce the possibility of oil staining on the material while also reducing maintenance requirements.

Differential Feed

The adjustable differential feed makes the MO-6704DA particularly useful when sewing knit fabrics and other materials that can stretch or pucker. The feed can be adjusted for stretching, gathering, or balanced feeding to help produce a smooth, professional-looking seam.

The MO-6704DA is well suited for:

• Garment manufacturing
