FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing a powder layer or granular layer of wood fibres on a bearing base to installation of distribution for making powder layer and structural panel. Method of producing a powder layer or a granular layer comprises feeding a powder or granules to rotating roller (6) and feeding powder or granules to first oscillating device (8, 9). Then feeding powder or granules to second oscillating device (11), wherein second oscillating device (11) oscillates in another direction than first oscillating device (8, 9). Then moving carrier (5) under first and second oscillating devices to obtain a powder layer or a granular layer on carrier (5). Second oscillating device (11) oscillates in a straight line and in a direction substantially parallel to direction of movement of carrier (5). Floor panel comprises a powder layer or granular layer made as described above. Scattering apparatus for production of powder layer or granular layer comprises rotating roller (6) and first (8, 9) and second (11) oscillating devices capable of oscillating. Second oscillating device (11) is configured to oscillate in another direction than first oscillating device (8, 9). Second oscillating device (11) is configured to oscillate in a straight line and in a direction substantially parallel to direction of movement of carrier (5). Scattering apparatus is designed so that powder or granules are loaded on carrier (5), which is supplied under roller (6) and first and second oscillating devices.
EFFECT: improved uniform distribution of powder or granular layer on carrier.
