Panelling for producing under=roof cover

摘要

The panelling (1) is made of bituminised wooden fibres in which the front and rear sides (2,3) are made parallel to each other. The two tongue sides (9,11) of the first narrow side (4) run at the same angle with respect to a plane defined by the rear side (3). The two tongue sides are arranged symmetrically in relation to a middle plane (13) between the front and rear sides. The greatest width of the groove (15) of the second narrow side (6) is smaller than the distance between the front and rear sides.
