Abstract
A pile of a plurality of panels includes at least one web of a hygiene- or wiping material. The web has a web width and a web length and is divided in its length direction in closely adjacent or partly overlapping separate or partly interconnected sheets, which in the longitudinal direction of the web extend between transverse separations or perforations. The web as well as the sheets are folded in accordion-like manner about transverse folding lines forming panel edges, so that panels are formed and piled on top of each other. The pile has a panel width constituting the distance between adjacent folding lines and a panel length which is the same as the panel width. The majority of the sheets comprised in a pile have a length, which is not divisible with the panel width.
