The L 850 is the ultimate Overlocker.
As the designer of the brand “Jolijou”, Andrea Müller creates colorful jersey fabrics and loves bringing them to life in new projects using the BERNINA L 850 overlocker. In particular, the One-step BERNINA Air Threader and the fast sewing speed with perfect stitch quality win this mother of three’s admiration when projects have to be done on a limited schedule.

If you also enjoy sewing with knits I'm sure you will love the Bernina L850 as much as I do
Andrea Müller Textile Designer „Jolijou"
The threads are magically moved through the machine via one simple step on the foot control. So both hands remain free. The L 890 automatically sets the loopers in the correct position for the air threader – no turning the handwheel or searching for the right position. Simply press the foot control and you're off!.


With the BERNINA Free Hand System (FHS) you can raise and lower the presser foot with your knee. In addition, the presser foot easily swings out for convenient access to the needles.
The L 850 offers several settings for Total Stitch Control - all individually adjustable. The best part? You can change all of these settings while sewing - including the thread tension, cutting width, stitch length and Micro Thread Control (mtc).


Not only can you sew quickly, but you can also sew stitch-by-stitch, making the flawless production of precise lines and curves a simple process. Plus, you will enjoy how extremely quiet the BERNINA L 850 sews. Program and control the maximum and minimum speeds via the color touch screen.

The space offered on the L 850 is generous by any definition. It has more room to the right of the needle and more work space height than any other BERNINA serger. Sew closed items with ease by simply sliding sleeves or cuffs over the convenient freearm.

The integrated needle threader and automatic needle stop up function make threading the needles simple. You can easily change from an overlock seam to a rolled hem or flatlock seam in no time because the thread remains in the same threading path.
