Classical V-Belt

Structure:

1,Shielding cloth : it is made of the special cotton canvas which ensure the belt to be elongation resistant and wearable , making the surface layer tough.
2,Buffered rubber: the rubber with good performance , high wearing resistance, low compress and distortion, which keeps the belt in normal shape during operation and protects the elongation resistant part (reinforce) in the belt.
3,Elongation resistant part(reinforce): the main part contributes to high strength of the belt, it is composed of polyester threads with high elongation resistance.
