An apparatus or plant for making pressed board from particulate or fibrous material, comprises a dispensing station for depositing such material on a movable surface, e.g. a conveyor and/or tray, a prepress for compacting the mat of this material and a multiplaten press for the final pressing stage. The prepress has at least two stages and is operated to compact the mat in these stages alternately, i.e., one mat is compacted in one stage of the prepress while a previously compacted mat is removed from the other stage and a new layer of the material introduced therein by alternatingly operable service mechanisms for charging and discharging the prepress.
