As we know, the web tension control system includes many products, such as air clutch, air brake, safety chuck, air expanding shaft. What is product used in paper making industry? 
 

In paper making procedure, tension control is a vital process, good tension control can make sure roller product winded and unwinded well and improve working efficience. If tension force too large, it will lead to paper stretch deformation even broken; if tension force too small, it will lead to paper layer and layer loose, so as to influence winding and unwinding quality. Tension force not stable, it will make web material lining speed changed and different tightness, so as to low yield.
 

Handong company design and manufacture the air clutch, air brake to match with safety chuck, air expanding shaft, so as to adjust web material tension force in even, and improve production yield.
