Abstract

A process for producing binder-containing fibrous mats from lignocellulose fibres or the like is described, in which the fibres are processed by hot pressing to shaped or moulded articles, such as for the internal lining of the passenger compartments of motor vehicles together with stabilizing additives. 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 heap densities of the synthetic fibres and the wood fibres, considered over the mat cross-section, are in accordance with a statistical distribution, which roughly corresponds to an edge-blurred, periodic comb profile. The base width for the synthetic fibres is much smaller than that for the wood fibres. The individual fibre heaps are interconnected by means of suitable adhesives.
