摘要： 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.

摘要： A separation unit for separating a web material along preformed lines of weakness. The separation unit has a width direction and includes at least a first roller having a rotational axis extending in the width direction and a web width extending in the width direction, and at least 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 at least one protrusion element extending perpendicularly 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.

摘要： A dispenser for dispensing at least one web from a stack of web material is disclosed. The dispenser includes a housing arranged to hold a stack of web material. A web path extends in an interior of the housing in a first direction in a first portion of the housing and in a second direction in a second portion of the housing. The housing includes an access opening providing access to the interior of the housing. The web path is accessible along a third direction, in both the first and second portions of the housing, via the access opening.
