Bernina L850 overlocker

Bernina’s L850 overlocker is fast, sewing at up to 1500 stitches per minute. It is also precise and quiet, and perfect for working with a wide variety of threads and fabrics in any combination. It sews, cuts and finishes in one easy step, so even sewing with difficult fabrics is made easy. 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.

The one-step Air Threader makes threading the looper threads unbelievably easy. Total Stitch Control ensures perfect overlock seams by offering several settings, all individually adjustable. With recommended default settings inexperienced users can immediately get started on their project. The experienced user has numerous options to personalize the settings for endless creativity. With Micro Thread Control (mtc), the amount of overedge thread can be precisely adjusted with a turn of the mtc knob.And you can change all of these settings while sewing – including adjusting the cutting width and stitch length. The result is a beautiful overlock seam ideally matched to your sewing project.

The infinitely adjustable differential feed provides smooth handling of knitwear and particularly prevents the unwanted ruffling of fine materials. You can also use the differential feed to create ruffles and gathers.

Threading the needles is simple thanks to the integrated needle threader and the automatic needle stop up function. One-path Threading with colour coding allows you to change from an overlock seam to a rolled hem or a flatlock seam in no time without changing the threading path.

The Bernina Free Hand System (FHS) is a knee operated lifter that raises and lowers the presser foot. That leaves both hands free to guide the fabric – a significant advantage when sewing corners, for example. In addition, the presser foot easily swings out for convenient access to the needles.

The work space offered on the Bernina L850 is extremely generous. It has more room to the right of the needle and more.work space height than any other Bernina overlocker. That means guiding fabric and accessing the presser foot lifter and needles is simple and more comfortable. Sew closed items with ease by simply sliding sleeves or cuffs over the convenient freearm. In addition, the large slide-on extension table expands the work surface area and simplifies the sewing of larger projects. The bright LED sewing light provides improved visibility when sewing, during both day and at night.

The Bernina L850 overlocker will allow you to take on a wider range of sewing projects, and give them a high quality finish.

One-step Bernina Air Threading
The One-step BERNINA Air Threader makes threading the looper threads unbelievably easy. No more dreading threading! One of the biggest advantages when threading both looper threads is both hands remain free. The threads are magically moved through the machine via one simple step on the foot control. Remarkably quick and easy! The L850 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!

Micro Thread Control (mtc)
This fine-tuning allows the amount of looping thread wrapped over the fabric edge to be fine-tuned, avoiding undesirable loose loops and creating a beautifully wrapped fabric edge. Thanks to the mtc fine-tuning, the thread tension only has to be adjusted once, because if there is a subsequent change in the cutting width or thickness of the material, it is sufficient to simply adjust the mtc fine-tuning. This saves you a lot of time because the fine adjustment of the thread usually requires lots of test seams and patience. With the easy-to-use mtc micro thread control, these multiple adjustments are not necessary because the mtc fine-tuning system includes the knife and stitch tongue

Differential Feed 
The differential feed is probably one of the best features of an overlocker. Two feed dogs, which are independent of each other and arranged one behind the other, feed the fabric and "push" or "pull" it under the presser foot. This either stretches or holds back the fabric during feeding, depending on the setting, keeping the seam or hem nice and flat without unwanted puckers. The differential feed can also be used t create ruffles/gathers, or stretch effects.
