Abstract:
An apparatus for separating fiber tufts from a fiber tuft-laden conveying air stream, comprising(a) a generally vertically oriented feed chute having an upper portion and a lower portion;(b) an air-pervious screen disposed in said upper portion and having an inner face;(c) an inlet channel having an outlet opening in said upper portion for introducing the fiber tuft-laden conveying air stream into said upper portion and for directing the fiber tuft-laden conveying air stream toward said inner face of the screen for effecting an impingement of the fiber tufts on said screen and a passage of the air stream, stripped of the fiber tufts, through said screen; and(d) a mechanism disposed in said upper portion of said feed chute adjacent said inner face of said screen for effecting a sweeping motion of the fiber tuft-laden conveying air stream back and forth over said inner face for removing a pressing force of the air stream on the fiber tufts against the inner face of the screen, whereby the fiber tufts fall off said inner face by gravity toward said lower portion of said feed chute.
