Abstract

Winding device and method for producing a web roll from a material web. The winding device includes a core being adapted to form a web roll, a core holder device, a core drive, a central roll, and a press roll arrangement. The press roll arrangement includes a web tension compensation roll and a mating roll positioned to contact the core at least at a start of winding. The method includes positioning a core in the core holding device, forming a nip between the core and the central roll, positioning a press roll arrangement against the core opposite the central roll, guiding the material web through the nip, and winding the material web onto the core to form a web roll.
