Air shaft is a special shaft for winding and unwinding.The shaft increased by the keys on the surface, which will be expand when the high-pressure gas filled in the shaft. Air shaft is easy to operate, the user only have the air supply with the air pressure controlled within 5-8kg/cm2. Just aired the shaft through the air value and when user want to lock the web. Just push the core activities of the air value to deflate, the keys will revert to its original appearance, the web can be removed easily.

Different shaft is a relatively advanced shaft for rewinding, which is suitable for users with higher require-ments. A multi-roll material can be rewind at the same time on one shaft. When a roll material is too tight, the slip ring will slip with the shaft to achieve a perfect rewinding. It effectively improve the slitting speed, winding accuracy and degree of automation.

Air shaft is widely used for winding, rewinding and slitting machines. It is widely used in printing, packag-ing, plastics, paper, glass, pharmaceuticals, electronic battery, textile machine and industry.
