A particle board, a fiberboard or an oriented strand board (25) is formed by the process according to the invention from a mixture of a comminuted cellulose material and a binder, especially a synthetic resin containing an unsaturated oligimer, that is hardenable by electron radiation. The process of the invention includes first forming a loosely scattered layer (4) of the mixture, e.g. on a conveyor belt, then compressing the layer in a press device (16), after performing a pre-compression in a pre-press in Some embodiments, and rapid setting of the layer (4) by means of electron radiation from an electron radiation device (22). Unlike the known processes that only use a thermosetting binder, the inventive method is hindered neither by heat transfer to the center of the board nor by a non-uniform humidity profile. High quality boards may be produced at a high yield without splitting and these boards require no conditioning storage.
