Method and device for winding of fiber webs, especially of paper and board webs

A device for winding paper or board webs, comprising:

• an unwinder for a full-width web;
• a slitter;
• wherein the unwinder is arranged to supply the full-width web to the slitter;
• wherein the slitter is arranged to slit the full-width web into at least a first partial web and a second partial web;
• a winding roll having a winding roll surface;
• wherein the winding roll is arranged to form a first winding station for winding the first partial web into a first partial web roll at a first nip;
• wherein the winding roll is arranged to form a second winding station for winding the second partial web into the second partial web roll at a second nip;
• a second guide roll arranged with respect to the winding roll surface to guide the first partial web onto the winding roll surface at least 120° before the first nip in the first winding station so as to wrap the first partial web starting at a first position on the surface of the winding roll, and from the first position wraps the first partial web about the winding roll surface with a first wrap angle of at least 120°;
• a third guide roll arranged with respect to the winding roll surface to guide the second partial web onto the winding roll surface at least 120° before the second nip in the second winding station so as to wrap the second partial web starting at a second position on the surface of the winding roll, and from the second position wrap the second partial web about the winding roll surface with a second wrap angle of at least 120°;
• wherein the winding roll is arranged to be driven to rotate in a wrapping direction, in which the first partial web and the second partial web are wrapped on the winding roll;
• wherein the second position is separated in the wrapping direction from the first position;
• and
• wherein a ratio of the first wrap angle and the second wrap angle is at least 0.8 and at most 1.25.
