Publication number: 20210085133Abstract: A separation unit for separating a web material along preformed lines of weakness. The separation unit includes a first roller, and a second roller having a rotational axis extending parallel with the rotational axis of the first roller. The rotational axis of the second roller is positioned at a distance from the rotational axis of said first roller. Each of the first and second rollers is provided with at least one protrusion element. Outer portions of the protrusion elements on the first roller are partially overlapping with outer portions of the protrusion elements on the second roller with a radial overlap length, thus forming an undulating passage for a web material between the rollers.
