Abstract
A fiber web is reeled by a reeling drum of a reel-up onto a parent roll. When the parent roll has reached the desired diameter size, reeling is changed from the parent roll onto a new parent roll. The web is cut by jet cutting means and the beginning part of the cut web is directed onto a reeling shaft of a new parent roll. The jet cutting path has a main cutting path and at least one edge area cutting path. The length of the main cutting path is at least 60% of the whole cutting path length from one edge of the web (W) to the other edge of the web (W). A turn-up device for a reel-up has one cutting module (15) and at least one nozzle (11) for jet cutting, which is attached movably and turnably to the module (15) by a cutting arm (12).
