The air Shaft is widely used on all kinds of machines when the machine need to wind the products. The air shaft can wind PE film, air bubble film, stretch film. It usuallywork with a hard paper tube. An airshaft is a kind ofdevice used for handling winding reels in the processing of web-fedmaterials, such as continuous-process printing press. Airshafts also called Air Expanding shafts are used in the manufacturing processes for fitting into a core onto which materials such as paper, card and plastic film are wound. An airshaft is designed so that, on fitting into a core, it can be readily expanded, thereby achieving a quick and firm attachment, it may also be easily deflated to facilitate easy withdrawal of the shaft after winding of product is complete. Their efficient design makes them ideal for mounting onto bearing housings to enable the winding or unwinding of rolls of stock material with the minimum of equipment down time. The advantage of using an airshaft is its ability to grip the core, without damage, whilst providing a positive interface to control the web via motors & brakes. Airshafts are available as either lug type (with bladder down the centre) or strip type (bladders on the periphery of the shaft).
