Abstract: A separation unit for separating a web material along preformed lines of weakness is provided. The separation unit includes at least a first roller, and at least a second roller having a rotational axis extending parallel with said rotational axis of said 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 said 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. The distance between the rotational axes of the first and the second rollers is adjustable, enabling the radial overlap length in the undulating passage to be variable.
