  • Publication number: 20200383530
    Abstract: 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.

  • Patent number: 10582814
    Abstract: A dispenser for interfolded napkins includes a container having a supporting surface for supporting a stack of interfolded napkins. The supporting surface extends in a horizontal plane, and is surrounded by side walls extending in a vertical direction perpendicular to the supporting surface. The side walls define a dispensing opening opposite the supporting surface. At least one tab is arranged in the container for retaining the stack of napkins during withdrawal of a napkin from the stack. The tab is pivotably arranged in relation to the container between a holding position, in which the tab extends horizontally over at least a portion of the dispensing opening, and a refill position, in which the tab is directed away from the dispensing opening. The tab pivots about a living hinge. One or more stop surfaces limit an extent to which the tab is able to turn about the living hinge toward the dispensing mouth.
