A method for manufacturing fiber boards comprising the steps of desintegrating the fiber raw material while exposing individual fibers from the same, diluting the fibers in water while forming a beating material which is distributed on an endless wire and dewatered while forming a fiber web which is cut into individual sheets intended to form boards, said sheets being transferred to a drying station in which the same are subjected to a heat treatment in order to produce stiff boards. As at least one fiber raw material packaging capsules made from thermoplastic-coated paper board are used, said capsules being coarsely decomposed and washed in a first step while forming individual clean paper board pieces which in a second step are treated in a desintegrator (1) in which they are defibrated while obtaining individual fibres on which the thermoplastic of the paper board coating is deposited. The heat treatment of the sheet is carried out at a temperature of at least 150 {C whereby the thermoplastic deposited on the fibers is melt and provides a strong binding of the fibers. |
