PNEUMATIC WINDING SHAFTS
It is difficult to give a standard overview. Pneumatic winding shafts are produced in many types, based on a number of basic principles. The diameters vary from 25mm up to 600mm and you can choose from square, triangular or round journals. Besides the standard double bearing shafts, there are also cantilevered versions available. This can make it a lot easier to work with the rolls.
If a pneumatic winding shaft is not suitable due to the roll weight or machine speed, then a pneumo-mechanical winding shaft can be used instead.
