Zusammenfassung:	A separation unit for separating a web material along preformed lines of weakness. The separation unit has a width direction and includes a first roller having a rotational axis extending in the width direction and a web width extending in the width direction, and a second roller having a rotational axis extending parallel with the rotational axis of the first roller and a web width extending in the width direction. The second roller is positioned at a distance from the first roller. Each of the first and the second rollers is provided with a plurality of protrusion elements being spaced along the rotational axes and protruding perpendicular from the axes. Each of the protrusion elements has a maximum width in the width direction, a maximum radial extension from the rotational axes, an inner portion adjacent to the rotational axes, and an outer portion remote from the rotational axes.
