Abstract (en)
[origin: WO2020099061A1] The invention relates to a method for winding a continuous material web (1), in particular a paper, board, tissue or other fibrous material web, in which method the material web (1) is successively wound onto a plurality of winding cores (2, 3) to form wound rolls (4), wherein the material web (1) is guided over a circumferential region of a winding drum (6) which forms a winding gap (8) together with the wound rolls (4) to be formed. The aim of the invention is to improve the grade change process in that the material web (1), during changing of a quality characteristic thereof, is severed upstream of the winding gap (8), said first, new web front-end is guided from the winding drum (6) into a pulper (7), and the material web (1), after reaching the desired quality characteristic, is severed again upstream of the winding gap (8) and the resulting second, new web front-end is wound onto a new winding core (3).
