Abstract: The present invention pertains to a process and devices for producing beam-shaped moldings from fine plant parts mixed with binders in molding presses. Based on the discovery that the degree of compaction of the core of such moldings decreases with increasing cross section of the moldings, it is suggested in the present invention that the core zone of the molding be formed by an additional amount of fine parts moved there and compacted deliberately, which amount of material acts reactively as a compression zone to the moveable walls surrounding it during the compaction of the molding. Compaction of the molding over its entire cross section and at the same time particularly great compaction of the peripheral zones of the molding are thus achieved. The strength and the bending resistance of such moldings are particularly high, and such moldings are therefore also suitable for forming railroad ties.
