ABSTRACT:
An apparatus for removing foreign matter from cotton includes an elongated frame having a plurality of rollers rotatably supported in closely spaced side-by-side relation therealong for conveying cotton over the rollers from one end of the frame to the other in response to rotation of the rollers in unison. The rollers have a plurality of protrusions so that the cotton is vertically shaken as it is conveyed over the rollers with the result that foreign matter falls between the rollers away from the cotton. The protrusions may be the transversely extended corners of polygonal shaped rollers, the corners being adapted to strike the cotton in response to rotation of the rollers for a more vigorous shaking action. A plate may be supported in vertically spaced relation above the rollers for rebounding cotton which is thrown up by the rollers back toward the rollers. A conveyor belt below the rollers collects the foreign matter which drops therethrough.
