The customer just aired the shaft through the air valve and when user want to lock the coils or web, and just push the core of the air valve to deflate, the keys will revert to its original appearance, then web can be dismantled simply.

Expanding shafts are widely used for winding, rewinding slitting ,printing, packaging, plastics, paper, glass, pharmaceuticals, electronic battery, textile machines or industries.
