Abstract: A retention mechanism in a dispenser for retaining an exchangeable roll of material, the retention mechanism includes a housing including a front wall. An insertion slot for a bearing pin of an end plug of the exchangeable roll extends along the front wall. A cam lock is arranged in the housing so as to be rotatable in a plane which is parallel to the front wall and to the direction of extension of the insertion slot. The cam lock includes a retaining member which is movable between an open position and a locked position by rotating the cam lock. When the retaining member is in the open position, the bearing pin can be inserted into the insertion slot, and when the retaining member is in the closed position, the bearing pin is retained in a locking section of the insertion slot.

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.
