ABSTRACT:
An apparatus for removing impurities from fibrous material such as cotton comprising a first and second clothed driven roller with said second clothed driven roller being in fiber transfer relation with said first clothed roller. A rotating cylindrical cage is provided for receiving said fibrous material from said second clothed roller by means of an air stream flowing through a passage which tapers towards said cylindrical cage. A suction is applied to the interior of the cylindrical cage for drawing air through the periphery of the cage for removing impurities from the fibrous material passing therethrough. Passages are associated with said first and second clothed rollers and have separating edges provided therein for aiding in removing impurities from said fibrous material as it passes over said rollers. In one embodiment, a plurality of calendar rollers and stripping and conveying rollers are distributed in sequence about the periphery of the cylindrical cage for increasing the cleaning action as the fibrous material is transported on the cylindrical cage.
