The overlock machine with automatic air threader
The overlock machine with automatic air threader from bernette. The hook threads are threaded in no time using the air threader. It has never been easier. The b64 AIRLOCK has more to offer: thanks to the free arm, closed sleeves and cuffs can be easily worked. A generous work surface provides space to the right of the needle, as does the included slide-on table. 5 LEDs brightly illuminate the working area. The presser foot can be lowered and temporarily raised with the knee lever, leaving both hands free to guide the fabric. There are 16 different stitches to choose from and a sewing speed of up to 1300 stitches per minute. So you'll be finished with your project in no time!

Automatic air threader for looper threads
Threading your looper has never been easier or faster thanks to the air threader. With the simple push of a button, each looper can be threaded individually or together.

5 LEDs in the sewing area
The well illuminated working area of the bernette 64 AIRLOCK facilitates sewing as well as the threading of looper and needles. The 5 LEDs enable precise and accurate work.

mtc thread control
Used for the first time on a bernette machine, the mtc thread control saves you a lot of time and effort and at the same time ensures a consistently high stitch quality, as you only have to adjust the thread tension once - even if you change the cutting width or fabric quantity.

Plenty of room thanks to the large working area (130 mm)
The 130 mm to the right of the needle adds a new dimension to overlocking. The generous working area makes it easy to guide large sewing projects, and it also makes needle and bobbin case tasks a whole lot easier: Changing the presser foot, attaching the top bobbin cover, and many more.

Free arm
The b64 AIRLOCK has a free arm to make it easier to sew round pieces like sleeves or trouser legs.

Large slide-on table for large projects
Easy to attach and included, the slide-on table makes sewing and fabric guidance even more comfortable, especially for large sewing projects. The fabric glides smoothly across the rounded table.

Free-Hand System (FHS)
The included knee lever leaves your hands free to comfortably position the fabric under the presser foot. You can also easily lift the presser foot with your knee by pushing the lever to the right.
