Wood fibers (2) which are used in the production of fiberboards are suppli ed from a metering device (1) through a feed chute (7) to a disintegration roll er (12) comprising a plurality of pins (13) on its surface. The disintegration roller (12) rotates at high speed, in such a way that the pins (13) deflect the fibers (6) hitting the disintegration roller (12). The fibers are entrained (6) by the pins (13) and fed through a chute section (17) formed by a partial section (15) of the roller periphery and a wall (16) lying opposite the latter, to an outlet orifice (18) of the chute section (17). Either a forming belt (19) of a forming machine i s located beneath the outlet orifice (18), or the fibers (6) pass the outlet orifice (18) into the air duct of an air fiber sifter. The disintegration roller (12 ) disintegrates irregularities in a fiber stream (6), e.g. fiber bundles, or drops of condensed water.
