Abstract: The invention relates to a method and to a plant for the manufacture of board-like composite materials having a surface structure at one side in which particles containing lignocellulose and/or cellulose, such as for example wood chips, wood fibers and the like, are mixed with at least one mineral binder, aggregate substances and water into a scatterable mixture. This mixture is formed on a continuously moved support into an endless mat, which passes, together with plate-like structure formers arranged end to end, into a continuously operating belt press. Thereafter provision is made for dividing up the length of board or mats obtained into individual sections, and for separating the plate-like structure formers from the individual boards or mats and returning them in a circuit into their starting position, while the individual boards or mats are subjected to a subsequent further hardening, curing and conditioning process. In this way considerable savings in investment and operating costs result.
