Abstract

Wood fibers (2) which are used in the production of fiberboards are supplied from a metering device (1) through a feed chute (7) to a disintegration roller (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 is 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.
