ABSTRACT:
Process for producing binder-containing fibrous mats from lignocellulose fibres or the like together with stabilizing additives is described. These mats are then generally processed by hot pressing to shaped or moulded articles, such as for the internal lining of the passenger compartments of motor vehicles. The dry fibrous material thoroughly mixed with the binder is applied to a conveyor in such a way that there is an alternate application of several wood fibre layers and synthetic fibre layers. The accumulation densities of the synthetic fibres and the wood fibres are placed to produce a mat cross-section in accordance with a statistical distribution, or curve, which roughly corresponds to an edge-blurred, periodic comb profile. The curve base width for the synthetic, fibres is much smaller than that for the wood fibres. The individual fibre accumulations are interconnected by means of suitable adhesives.
