JUKI MS-1261F 3-Needle Feed-Off-the-Arm Double Chainstitch Industrial Sewing Machine

Juki MS-1261F Feed-Off-the-Arm Double Chainstitch Machine (6.4mm Gauge) The Juki MS-1261F is a leading double chainstitch machine designed for heavy-weight materials, ensuring higher operational efficiency and superior finished product quality.

Reliable thread tucking by the looper prevents stitch skipping The feed mechanism has been optimized to reduce material feed when needles enter, preventing needle bending. Consistent bobbin thread clamping ensures uniform thread loops. The looper reliably tucks the needle thread to achieve consistently uniform seams.

Consistent material feeding for seamless seams Increased feed dog teeth easily grip overlapping material. A modified presser foot shape prevents single-sided contact with overlapped areas. The rear movable needle guard includes a vertical adjustment mechanism, enhancing smooth heavy-weight material feeding and preventing stitch skipping.

Beautifully finished seams even with heavy-weight materials A thread guide between the needle bar thread take-up and intermediate tension release lever allows precise timing adjustments for needle thread tension, reducing bobbin thread tension. This results in beautifully finished, soft-looking stitches even with heavy-weight materials.

Prevents uneven material feed Height differences between the feed dog and presser foot sole can be adjusted to suit material thickness. Optional folders ensure smooth material feeding, while an improved cloth puller prevents uneven material feed.
