VariFlex™

Winder as a productive, flexible system solution

VariFlex is a winder that is based on two-drum winder technology. With its different roll and cover combinations, it is designed for various paper grades and provides for constantly high productivity.

Two winder drums make up the VariFlex roll bed. At the beginning of the winding process, the nip pressure required for optimal winding tightness is built up by a rider roll. With increasing diameter, the growing dead weight of the paper rolls takes over this function.

Newly developed elastic covers for the winder drums such as ElaGrip™ and ElaCare™ are used for the constantly increasing line loads starting at a certain paper roll weight. They substantially extend the paper qualities and paper roll diameters of the VariFlex.

The VariFlex™ winder is used for winding in a wide range of grades. It is also used as a rewinder for quality assurance or elimination of problem spots in the finished roll.
