Abstract
A mechanism for eliminating impurities from fibrous material, in particular cotton, having at least two card-clothed rolls (22, 23) arranged after a feed mechanism and a screening drum (3) to which said fibrous material is fed by means of an airstream. A housing closely encloses the two card-clothed rolls. Interposed in the housing are separating openings including separating edges. One of said two card-clothing rolls (23) cooperating with the other of the two card-clothed rolls has a take-off and loosener roll for the fibrous material and the centrifugal forces at the circumference of the second card-clothed roll (23) being greater than at the first card-clothed roll (22). A third card-clothed roll is positioned in carding relation with the first card-clothed roll. Another take-off and loosener roll (52) is positioned for removing fibers from the third card-clothed roll (5). A pair of fiber feed channels (24, 53) extend from the take-off rolls (23, 52) for conveying the fibers therefrom to the screening drum (3). The widths of the mouth of the channels (24, 53) are one-half of the width of the screen drum (3) so that each of the fiber conveying channels (24, 53) feed fiber material to one-half of the screening drum (3).
