Pneumatic expanding shafts

Pneumatic expanding shafts are used for winding and unwinding rolls of materials in many areas of converting industry. By inflating the shaft, you will increase its diameter and thus perfectly fix the internal diameter of core. Using the shafts, you can then transfer torque to a roll - to brake when unwinding or to drive when winding. Clamping shafts are a very common standard in the paper industry, blowing plastic films, making glass fiber mats, nonwoven fabrics, flexible packaging, printing, packaging and other industries.
