Abstract (en)
[origin: EP0006098A1] The plasterboard panel has chamfered lengthwise edges, and the transverse edges are likewise chamfered for the whole panel width, and typically at the same angle. The panel can be made by making a sufficiently wide and deep saw cut over its entire width after manufacture to form a forked edge, which is then compressed to give the chamfer, the saw cut being filled with glue to increase its strength after compression. Alternatively, before parting the panel off a progressive pressure can be exerted by a roller on the panel end portions.
