BERNINA L 660: Fast, Precise Overlocking Professional Overlocking
Professional Overlocking
The BERNINA L 660 creates clean, professional seams, rolled hems, and flatlock using 2, 3, or 4 threads, with 18 stitch patterns at up to 1,200 stitches per minute. A powerful, quiet DC motor delivers consistent piercing power on any fabric.
Effortless Air Threading
- One-Step BERNINA Air Threader for the loopers
- Color-coded one-path threading
- Same threading paths for every stitch
Hold the threads over the air threader, press the foot control, and the threads are drawn in by air. With the needle stop up, the loopers move to the correct position automatically, no handwheel turning required.
Differential Feed and Micro Thread Control
- Stepless differential feed, 0.7 to 2
- mtc Micro Thread Control
- Smooth, pucker-free seams
Stepless differential feed keeps delicate and stretchy fabrics smooth and free from puckering, while Micro Thread Control fine-tunes the looper thread for perfectly balanced stitches, even while you sew.
BERNINA Free Hand System
- Knee lifter raises the presser foot
- Drops the feed dog at the same time
- Both hands stay free to guide the fabric
The built-in Free Hand System lets you raise the presser foot and drop the feed dog with a knee lifter, giving you more clearance and full control when positioning even the thickest fabrics.
Programmable Needle Stop
- Needle stop up or down
- Stitch-by-stitch sewing
- Back-kick foot control
Program the needle to stop up or down, and use the back-kick on the BERNINA foot control to raise or lower the needle by half a stitch for precise starts and stops.
Fast and Precise
Adjustable stitch length and cutting width from 3 to 9 mm, an integrated upper looper converter, and a knife you can deactivate from the outside make the L 660 ready for any seam. A slide-on table is included for larger projects.
