ABSTRACT A process for the hot press moulding of moulded articles, such as the internal linings of motor vehicles or the like is described, in which planar blanks of tangled fibre mat fleece mixed with binders, using at least one mould, are permanently deformed in a multidimensional moulding process after evaporating on the mat fleece. A stabilizing support is introduced during the deformation process on at least one side between the shaping surface of the mould and the mat fleece. It is in the form of a fibrous sand- wich layer which is substantially elongation-free in the surface direction at ambient temperature, but is plastic- ally deformable within the hot press mould under the action of heat. With and/or immediately after the moulding process, said stabilization support becomes a substantially elongation-free, inflexible covering. The geometry of the flexible stabilizing support is to be made to coincide with that of the mat fleece blank to be deformed.
