Abstract

In a device for feeding flocculent fiber material to processing machines, comprising an upper filling chute (1) arranged in a housing, at the lower end of which a feeding roller (8) is arranged cooperating with a beater or opening roller (9) from which a feeding chute (6) branches tangentially, the filling chute (1) and the feeding chute (6) having at least one at least partially air-permeable chute wall (2, 11), an additional pneumatic compacting being performed in the feeding chute by injecting a compacting air flow (C), and the flow of transport air (A) being discharged at the air-permeable chute wall (2) of the filling chute (1), it is provided that the flow of transport air (A) is discharged within the housing (7) into an exhaust air chute (3, 4) that is substantially parallel to the filling and feeding chute (1, 6) to an exhaust air connecting member (5) arranged downstream of the air-permeable chute wall (11), and that a partial air flow (B) of the flow of transport air (A) is supplied into the feeding chute (6) as the flow of compacting air (C) at a branching point between the filling chute (1) and the feeding chute (6), and that the flow of compacting air (D) escaping from the air-permeable chute wall (11) of the feeding chute (6) is guided into the exhaust air chute (4) downstream of the branching point.
