Abstract (en)
[origin: WO03030144A1] The aim of the invention is to improve the production of thin panels, in particular that are provided with a pattern of recesses or protuberances and/or slit-type perforations. To achieve this, the recesses (13) or prominent sections (12) are slit on at least one side; the slits (2) can be offset individually and/or in groups (12, 12a) in relation to one another, in such a way that part of each slit (2) or group of slits (2) is offset in relation to neighbouring slits (2a) or groups of slits (12a).
