With the VariTop single-drum winder, the line load can be precisely controlled independently of the roll weight. Each paper roll is guided in its own winding station, which allows cores of different diameters to be used and different winding rolls to be produced.
With the VariTop, laterally shifted rolls provide for weight unloading, whereby firm but gentle winding becomes possible. Due to the advanced automation, e.g., butt splicing, automatic set changing, gluing at the beginning and at the end, etc., virtually continuous operation is possible.
VariTop is suitable for LWC and SC paper and is used in both rotogravure and offset printing.
