The adjustment method and function of the weft stop lever spring tension

Weft stop lever spring tension adjustment is very 

important, spring tension adjustment is too small, 

will cause the weft stop failure. Tension adjustment 

is too large, will cause the weft stop wrong stop. 

The finer the diameter of the weft wire, the weft 

stop lever on the spring tension is adjusted to the 

smaller, but the minimum tension must be able to 

make the left end of the weft stop lever contact 

weft stop contacts. Changing the action length of 

the spring and the size of the spring can change the 

tension of the spring, which is usually less than the 

tension of the weft wire.
