. Abstract of the Disclosure Resin treated lignocellulosic fibers are conveyed by a stream of air downwardly in a separator containing one or more doffing rolls, which rotate adjacent a perforated so roll assembly that is connected to a vacuum which draws dust and foreign parti- cles out of the fibers as they fall through the separator to a hopper located in the rear of the feeder housing. From here the fibers are fed by endless belts to the top of the expansion chamber formed in the rear of a housing containing one above the other a pair of endless screen condensers. The fibers cascade downwardly in the expansion chamber to a generally wedge-shaped air bridge formed at the inlet end of the space between the confronting runs of the condensers. This space is connected to a suction source so that the fibers are slightly compacted as they are sucked through the air bridge and deposited on the confronting runs of the con- densers. These two runs travel continuously toward the discharge end of the housing to produce an endless mat of fibers at the output. The upper belt is also mounted for vertical adjustment to vary the thickness of the mat.
