Zusammenfassung:	Procedure for the fabrication of blank for a structural product, such as a blank for a structural board, from material (1) comprising longer (L) and shorter (S) particles and possibly also particles (F) smaller than these, said particles being e.g. chips and/or fibres, in which procedure the particles are mixed with a binding agent and possible additives and passed into at least one blank former, from where the particles are brought onto a base (10), e.g. onto a belt conveyor or into a mould or onto a blank. The particles are brought onto the base (10) in given orientations so that at least part of the particles are oriented in a direction differing from the orientation of other particles.
