Abstract (en)

[origin: WO8903439A1] A hopper feeder for producing a mixture of fibrous material has a chute, a bottom conveyor belt and a working unit operating in a working direction, e.g. an elevator lattice. The device for feeding the fibrous material to the chute is moved back and forth above the latter. An inclined surface (4), for example a slide plate, slopes downward in the working direction in the lower section of the chute. The inclined surface (4) extends at least half-way along the bottom surface (5), e.g. of a bottom conveyor belt.
