Sunrise air 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 Air Shaft 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 facility 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 Air Shaft is its ability to grip the core, without damage, whilst providing a positive interface to control the web via motors & brakes. Air Shafts are available as either Key/Lug Type (with bladder down the centre) or Board/Leaf Type (bladders on the periphery of the shaft)

The air shaft introducing foreign advanced production equipment and fabrication technology, using imported balloon, the shaft is casting by aluminum alloy, shaft body plating chromium, accurate assembly, convenient to use and long operating life. When using, match with our company's professional configuration of the aerate gun filling gas for the nozzle jet, to make the shaft of off-axle appearance uniform expansion, thereby lock nitrogen-treated barrel, when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.

Performance and advantages: Air shaft in practical applications, it has advantages of convenient operation, quick, without damage rolls etc.

Product usage: It is widely used in printing, cutting, coating, compounding and other machineries' releasing and winding scroll.
