Working Principle of The Weft Stop Lever--When The Loom is Operating Normally

During normal operation of the loom, the right end 

of the weft stop lever is pressed down under the ten

-sion of the weft wire, and the left end of the weft 

stop lever is lifted up to leave the weft stop contact. 

When there is a weft break, the weft wire does not 

act on the weft stop lever, and the left end of the weft 

stop lever contacts the weft stop contact under the act

-ion of its tension spring, so that the weft stop circuit 

is energized, resulting in a stop.
