Double Needle Sewing Machine Jumping thread is a common sewing problem, thread jumping will cause the needle thread to be uneven and affect the sewing effect. Here are some common jumper adjustment methods for twin needle Sewing Machines:
Adjust the thread tension: Jumping threads may be caused by unbalanced thread tension. Therefore, it is necessary to check whether the tension of each thread is consistent one by one. If you find that the tension is inconsistent, you can adjust the thread tension screw. The adjustment method is to turn counterclockwise to reduce the tension, and turn clockwise to increase the tension. In addition, it is also necessary to check whether the line is correct and whether there is any winding or tension.
Adjust needle board spacing: Needle board spacing is also a common cause of skipped threads. It is necessary to turn off the Sewing Machine, adjust the needle plate distance with a needle adjusting plate screwdriver, and adjust the distance to a suitable position.
Adjust the position of the needle eye: The position of the needle eye also has a certain influence on the sewing effect. If the thread jump is caused by improper needle eye position, you can try to adjust the needle eye position. It is necessary to remove the needle plate, and then fine-tune the needle eye up, down, left, and right until the needle eye is in a proper position.
Replacing the needle: If none of the above methods can solve the jumper problem, consider replacing the needle. The quality and shape of the needle will affect the sewing effect. If the needle is worn out or the shape is not suitable, it needs to be replaced with a suitable needle.
