Winding technology

Our expanding shafts are tailored to suit your needs. The expansion principle can be chosen according to your preferences and requirements: pneumatic, mechanical or even combined. The pneumatic expansion principle is solved using a central hose or flat hoses. Mechanical design is solved by cone.

The key information for designing a particular solution is load information - maximum weight of rolls, their maximum and minimum width, or number of rolls clamped simultaneously, inside and outside diameter of the clamped core, unwinding / winding speed, material and its thickness, belt tension, torque, eventually drawing of ending pin etc.
