To Learn the Working Principle of the Warp Stop Motions

The warp stop motions are fixed to the bracket which 

is insulated from the machine body. The core plate of 

the motions is connected to the warp stop conductor 

(12V low voltage conductor). The warp stop motions 

are connected to the warp stop wires (12V low voltage 

wires). When the core plate of the warp stop motions 

is not in contact with the warp stop motions, the loom 

rotates normally. When the warp breaks, the drop wire 

falls down, and then the drop wire contacts the core 

plate of the warp stop bar, causing the warp stop circuit 

to conduct, causing the magnetic starter motor to stop, 

and the weaving machine to stop.
