Key type air shaft, Lugs manufacturing machines
What is an Air mandrel ?
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 center) or Board/Leaf Type (bladders on the periphery of the shaft).
