Juki MO-6814S 4-Thread Industrial Overlock Machine Features
High-Speed Sewing with Excellent Seam Quality
The Juki MO-6814S is engineered to produce beautifully finished seams even when operating at high speeds of up to 7,000 stitches per minute. Its needle thread take-up mechanism and looper thread take-up lever help maintain consistent thread tension, producing soft, well-balanced seams that respond effectively to the elasticity of different fabrics.
The machine is suitable for a wide range of sewing materials, from lightweight fabrics to heavier materials. Its wider and brighter needle entry area improves visibility and responsiveness, making operation easier and more comfortable for the user.
Reduced Noise and Vibration
The optimally balanced machine design helps reduce operating noise and vibration, providing a smoother and more comfortable sewing experience. This makes the MO-6814S suitable for demanding production environments where reliable performance is required throughout the working day.
Easy Differential Feed Adjustment
The MO-6814S features convenient adjustment mechanisms that allow the operator to fine-tune the machine according to the material being sewn. Differential-feed micro-adjustment, differential feed ratio, and main feed dog height can be adjusted from the front of the machine, making it easier to achieve the desired stitch quality.
Flexible Fabric Handling
The differential feed system supports both gathering and stretching applications, helping prevent unwanted fabric puckering or stretching. This makes the machine suitable for knitted fabrics, stretch materials, garments, and a wide range of industrial sewing applications.
