 will. Melamine-phenol or resorcinol resins have proven to be particularly suitable on their own or in a mixture with urea resins.



   It has also been shown that the following mixing ratio of the mass to be molded allows easy processing and gives the moldings particularly good properties:

    PATENT CLAIMS:
1. Process for the production of molded bodies, in particular plates, pipes, dowels and the like. Like., which consist of base material and organic binders, by casting, spraying, rolling or pressing using lignite material as the base material, characterized in that the base or filler fiber lignite with a fiber length of predominantly over 1 mm, optionally mixed with change known basic resp. Fillers, is used.

Claims (1)

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass der überwiegende Teil der Lignitfasern eine Länge von l, 5 bis 3, 5 mm besitzt. 2. The method according to claim 1, characterized in that the majority of the lignite fibers have a length of 1.5 to 3.5 mm. 3.
