Abstract
An arrangement used for filtering out conveying air when supplying fiber material to a processing machine is provided. The arrangement has an essentially vertical filling chute for the fiber material, the chute having an upper intake opening and a lower exit opening, a device with pneumatic fiber feed at the upper intake opening, and a floccule-forming device at the lower exit opening including a system of draw-in rolls and a fast-rotating opening roll. The chute includes at least one air-permeable surface for separating the fiber material from the conveying air. An evacuating device evacuates the filtered out conveying air. An exhaust air device is coupled to the evacuating device and has an air stream regulator which is connected to a control and regulating device. The conveying air stream is guided along the opening roll, and a partial air stream of the filtered out conveying air is guided into the exhaust air device.
