Abstract:
A method of manufacturing composite materials having a structured surface at one side, wherein particles containing at least one of lignocellulose and cellulose are mixed with at least one mineral binder, water and optionally aggregate substances into a mixture which is capable of being scattered and this mixture is formed on a continuously moved support into an endless mat, with the surface of the support confronting the mat having a surface structure or with a structure giving means being applied onto the surface of the formed mat, whereina) plate-like structure formers with a relief-like surface structuring in the matter of wood grain, slate, sandstone or a fanciful structure are used, which are placed end to end onto the endless mat or onto the support,b) the endless mat together with the plate-like structure formers are pressed in a continuous pressing process into a board or into a mat which does not spring back resiliently,c) the mat which has been pressed in this way is split in the region of the points of abutment of the plate-like structure formers into individual board or mat sections,d) the boards or mats which are obtained are separated from the plate-like structure formers or these structure formers are separated from the obtained boards or mats, ande) the plate-like structure formers are returned in a circuit into their starting position and the boards or mats separated from the structure formers are further treated.
