Air shaft is a special shaft for winding and unwinding. The shaft is designed by the key/leaf/lug on the surface, which will be expanded when the high-pressure gas filled enter into the shaft inside. 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.
Core shafts and expanding shafts are used to handle winding rolls in the processing of web-fed materials. They are worked with equipment such as continuous-process printing machines. Mandrels and air shafts are similar to the axles on an auto. They apply as the connection between the motor that drives the reel-winding application and the roll itself.
