Abstract: A method of manufacturing molded parts, preferably having the same wall thickness, from mixtures of cellulose and/or lignocellulose fibers with more than 20% by weight of thermal binders, in which the molded article results from application of heat and pressure to fiber mat prefabricated therefrom. In a first step, the fiber mat undergoes preliminary compression as a planar, endless matted fiber fleece, with only a small degree of compression of the fiber composite, the matted fiber fleece containing at least 2% by weight of a binder which cross-links under heat, its "start-off temperature", i.e. the temperature at which cross-linkage begins, being lower than the softening temperature of the thermoplastic binder. The cellulose and/or lignocellulose fibers are provided, before production of the fiber composite, with a surface finish of the cross-linking binder.

Abstract: A method for the production of laminated moldings, such as internal linings or panellings of motor vehicles and the like, and dimensionally stable parts in which a support part is provided with a surface lamination and in which initially a preform having the same volume as the support part, but not having the same surface area with respect to the final shaping, is produced. Utilizing the inherent production heat, the preform is then connected by pressure action to the lamination by back-embossing with the thermoplastic material of the support part and is given its final shape by material flow processes. The invention improves back-embossing in the production of laminated moldings in such a way that with reduced embossing forces the surface-unitary adhesion of the lamination to the support part is improved and the risk of bubble formation is eliminated.

Abstract: An overhead lining for vehicular inside roof linings of passenger cars is described, which is designed as self-supporting, integral shaped bowl. The overhead lining is made by compressing a mat of refuse nonwoven fabric, while exerting a pressure thereon at an elevated temperature. For this purpose, the refuse nonwoven fabric is made up of a mixture of at least 30 percent up to a maximum of 90 percent of partially stretched polyester fibers with parts of polyester high-bulk fibers, supplemented to 100 percent. The weight per unit area of the finished shaped bowl is between 600 and 1,200 grams per square meter, and the thickness is between 1 and 10 millimeters. The shaped bowl, on its one visual surface, is lined without an additional cement being used. The wall thickness of said shaped bowl may vary across its surface, and compaction of said shaped bowl, in the regions of its mounting elements, may be higher than in other regions.
