<p>The invention relates to a method for separating partial webs in a slitter-winder, in which method the partial webs (WP) are separated by spreading in a spreading device comprising at least a first, bowed spreader roll (14) fitted at one side of the partial webs (WP) and a second, bowed spreader roll (15) fitted at the opposite side of the partial webs. In the method the partial webs (WP) are guided over the bowed spreader rolls (14, 15) so that the wrap angles (B14, B15) over the spreader rolls (14, 15) are substantially unequal. In the method the partial webs (WP) are guided to the first spreader roll (14) in lead-in direction (Dinxy) in XY-direction and the partial webs are guided from the second spreader roll (15) in lead-out direction (Doutxy) in XY-direction such that the lead-in direction (Dinxy) and the lead-out direction are substantially divergent.</p> |
