ABSTRACT:
An apparatus for feeding fiber material to a fiber processing machine includes a vertically-oriented fill chute having an open top, a bottom and a generally rectangular cross section of opposite narrow sides and opposite wide sides; a duct having an open end communicating with the fill chute adjacent the top thereof at one of the wide sides for introducing a fiber material-carrying airsteam into the fill chute; air outlet openings provided in the fill chute for allowing passage of air from the fill chute; and a discharging arrangement for withdrawing fiber material from the bottom of the fill chute. The duct has a terminal length portion ending in the outlet opening and the terminal length portion has an at least approximately quadrate cross section. There is further provided a space of impact between the outlet opening and the open top of the fill chute; the outlet opening is at least approximately centered with respect to a horizontal middle of the space of impact.
