Bernette B64 Airlock Serger
Manufacturer number: b64
Manufacturer number: b64
Your overlocker for everything from sweatshirt fleece to denim.
The bernette 64 AIRLOCK’s air threader threads the loopers automatically – it’s never been so easy to get started. The free arm makes sleeves and cuffs easy, and you’ll love the large work surface to the right of the needle and the slide-on table. 5 LEDs light the working area, and the bernette Free Hand System lowers and raises the presser foot so your hands stay free to guide the fabric. With 16 stitches and a sewing speed of up to 1,300 stitches per minute, you’ll finish projects in no time.

Automatic air threader
Thread each looper separately, or both together, with one push of a button – and color-coded threading paths make the rest simple.


5 LEDs in the needle and working area
A well-lit workspace makes sewing and threading the loopers and needles easier and more precise.
Micro Thread Control (mtc)
Set the thread tension once – mtc keeps stitch quality consistent even when you change the cutting width or fabric thickness.


Large working area (130 mm)
130 mm of space to the right of the needle gives you room for heavy projects and for tasks like changing the presser foot or attaching the upper looper converter.
Free arm
Sewing tubular projects such as cuffs, legs and necklines is easy with the free arm.


Super-large slide-on table
The included slide-on table makes guiding fabric more comfortable, especially for large projects.
Free Hand System (FHS)
With the included knee lifter, your hands stay free to position the fabric – just push the lifter to the right to raise the presser foot.
