Patent ID: 7094309

Claim:
A process of gluing dried fibers which are designated for the production of fiberboards, comprising the following steps: (a) supplying said fibers to a fiber roller, said fibers being supplied by a metering device through a feed chute, said fiber roller having a plurality of pins, said metering device having an outlet and said feed chute having an outlet orifice; (b) deflecting said fibers by rotating said fiber roller so as to deflect said fibers by said pins, said fibers being directed along a chute section which is defined by a partial section of the periphery of the fiber roller and a wall lying opposite said partial section of the periphery of the fiber roller and which chute section extends from said outlet orifice of said feed chute in a rotational direction of said fiber roller, wherein said fibers are accelerated to approximately a peripheral speed of the fiber roller by the rotation of said pins and an air flow generated by said pins; (c) exiting said fibers from an outlet orifice of said chute section in a substantially horizontal direction; (d) deflecting said fibers downward in a deflection region of a pneumatic conveying device, said pneumatic conveying device having an inlet disposed adjacent to said outlet orifice of said chute section; and (e) gluing said fibers when being deflected with at least one spray nozzle which expels glue and air.
