Patent ID: 7987884

Claim:
An apparatus for making fiberboard, the apparatus comprising: an arcuate and elongated fiber-deflection conduit having an intake end and a downwardly open outlet end; a plurality of partitions extending longitudinally in the arcuate fiber-deflection conduit and subdividing same internally into a plurality of arcuate and longitudinally extending subconduits extending between the intake end and outlet end; fiber-supply means for blowing fibers with air into the intake end of the deflection conduit and longitudinally through all the subconduits; a laterally closed vertical chute extending downward from the outlet end of the deflection conduit, whereby fibers exiting the subconduits at the outlet end drop as a stream in the chute; means including nozzles between the outlet end and the chute for spraying fibers into an upstream end of the stream and thereby coating the fibers; and collection means underneath the chute for catching and conveying away the glue-coated fibers as a mat.
