The One-step BERNINA Air Threader

• Simple threading with air
• Now, you’re ready to sew
• Imaging threading that is actually fun

The looper threads are magically moved through the machine by air with one simple step on the foot control. Now both hands are free to guide the threads. The L 850 automatically sets the loopers in the correct position of the air threader – no turning the handwheel or searching for the right position.
