Industrial Overlock Sewing Machine JUKI MO-6914S-BE-640H

JUKI MO-6914S-BE-640H — Industrial High-Speed 2-Needle Overlock Machine with Extra High-Throw Upper Looper for Medium to Heavy Knit Fabrics

The JUKI MO-6914S-BE-640H is a super-high-speed 2-needle overlock machine from the MO-6900S Series, engineered specifically for medium to heavy-weight knit materials such as sweaters. With a 2.0 mm needle gauge and 4.0 mm overedging width, the machine delivers stable seam geometry suited for knit garment assembly and runstitching operations. The extra high-throw upper looper configuration enhances loop formation and thread control, ensuring consistent seam quality even when processing thicker knit structures.

What Sets JUKI MO-6914SBE640H Apart?

Developed for demanding knitwear production environments, this model combines dual thread take-up mechanisms, reinforced feeding performance, and durability-focused construction to support reliable sewing of elastic and bulky materials. The extra high-throw upper looper improves loop reach and stability, making the machine particularly effective for multi-layer knit assemblies and high-speed operation.
