Abstract
Winding device and process for winding wound rolls. The winding device includes a pressure roll axially divided into separate sections and a winding arrangement. The pressure roll is arranged to be placed on the winding arrangement. A coupling device is arranged to axially couple the separate sections together, and a drive unit is arranged to commonly rotatably drive the axially coupled separate sections. The process includes axially coupling the separate sections of the pressure roll together with the coupling device, rotatably driving the axially coupled separate sections, and pressing, at a beginning of a winding procedure, the separate sections of the pressure roll against the wound rolls.

- wherein said positioning drive is arranged to separately move said separate sections.
A winding process for winding wound rolls from partial webs cut from a material web, in an apparatus that includes a pressure roll axially divided into separate sections, coupling device arranged to axially couple the separate sections together, and a drive unit arranged to commonly rotatably drive the axially coupled separate sections, said process comprising:
- axially coupling the separate sections of the pressure roll together with the coupling device;
- rotatably driving the axially coupled separate sections;
- and
- pressing, at a beginning of a winding procedure, the separate sections of the pressure roll against the wound rolls.
A process for winding wound rolls from partial webs cut from a material web, in an apparatus that includes a pressure roll axially divided into separate sections, coupling device arranged to axially couple the separate sections together, and a drive unit arranged to commonly rotatably drive the axially coupled separate sections, said process comprising:
- axially coupling the separate sections of the pressure roll together with the coupling device;
