The thread dividing piece of the computer flat car (also called a sewing machine) is one of the key components that guides the line to the sewing machine. Generally speaking, the branching piece of the computerized flat car is located on the left side of the machine head. The correct position can be determined by following the following steps:
1. Open the machine head cover of the sewing machine and guide the line to the branching line film place. A breakout piece is usually a small plastic piece with two or more holes through which the wiring needs to pass to reach the sewing machine.
2. Confirm whether the circuit passes through the hole of the breakout piece correctly. The wire should pass through one hole in the breakout, pass through the line guide plate (usually a metal plate), and exit the breakout through the other hole.
3. Confirm whether the circuit is correctly connected to the corresponding parts on the sewing machine. The line should be guided to the tension adjuster, guide pulley, thread rod and other components on the sewing machine, and finally to the needle of the sewing machine.
It should be noted that the position and use method of the splitting piece of the computer flat car of different models and brands may be different. For specific operating steps, please refer to the instruction manual of the sewing machine.
