ABSTRACT:
In this machine, tufts of fibers are delivered from a feed section by an air bridge into a generally vertical chute past a rotary feeder condenser on which the fibers are formed into a mat which is carried onto a feed plate over which the mat is fed by a feed roller into a lickerin rotating at high speed. The lickerin, which is vertically below the condenser, combs fibers from the mat. The fibers are doffed from the lickerin through centrifugal force and by an air stream flowing past the lickerin. The air stream conveys the fibers through a generally vertical duct to an endless belt screen condenser on which they are deposited to form the random fiber web. The air is recirculated past the lickerin to aid in doffing the fibers from the lickerin.
