HimaPro Automatic Electric Bobbin Winder – Adjustable Bobbin Slot – Fast and Efficient Winding Experience

Highly Compatible: Adjustable bobbin slot to fit for most kinds of bobbins, like bobbins of A style, L style, and M style. Also works for class 15J, class 66, Bernina #0115367000, Juki 270010 bobbins. It may NOT work for Husqvarna Viking-specific bobbins. Save Time & High Efficiency: 110V – 240V AC, high-speed electric motor; auto stop when the bobbin thread is full. A Complete Set: Units including the base plate and the thread stand can be easily installed on your sewing table. Easy to Operate: Thread tension can be adjusted by the tension assembly unit. Press the ‘Start’ & ‘Stop’ buttons to turn the motor on or off. Two Black Sensors: The position of the sensors can be adjusted by using a screwdriver. If your bobbin does not fit at first or the bobbin winder stops unexpectedly during use, definitely try and adjust the sensors first. Tangent Line of Your Bobbin: The edge of your bobbin should be in line with the middle point of the sensors. This is the reason that our bobbin winder stops on its own: the sensors will detect the fullness of your bobbin and will then stop the motor. Tension Knob/Tension Adjustment Disc: You can adjust the thread tension by rotating the tension knob clockwise or counterclockwise. Start & Stop Buttons / Thread Cutter: To start or continue the winding process, simply press the “START” button; To stop winding, press the “STOP” button. The HimaPro Automatic Bobbin Winder will stop on its own once the bobbin is full of threads. Then you can pull out your bobbin and cut the thread by using the thread cutter on the side.
