What is the function of a unwinder ?
Unwinders take on the task of unwinding the web-shaped material wound on a core or without a core and feeding it to the subsequent process. A basic distinction is made between the two types of winding, contact winder and center winder. With the contact winder, the material roll on top is driven by one or more contact rollers or drive belts. A widespread variant of the contact winder is the support rollers or ascending batch winder where the material roll acts supported on 2 rollers arranged in parallel. The contact winder can be used where there are no special demands on the surface of the material to be wound.
With the center winder, the material is picked up in the winding center. Depending on how sensitive the winding material reacts to tensile and compressive loads, the unwinding process is either mechanically braked or supported by a motorized web tension control.
