ABSTRACT:
An apparatus for forming a lap from fiber tufts has a generally vertically oriented feed chute having upper and lower ends; a mechanism disposed at the upper end for introducing fiber tufts into the feed chute; a mechanism at the lower end for discharging a lap from the feed chute; a mechanism for maintaining, in the feed chute, an air stream flowing downwardly in the direction of the lower end; and apertured separating walls bounding the feed chute along a vertical length portion thereof for providing an exit for the air stream from the feed chute. Each separating wall has a plurality of parallel-spaced, vertically extending slots and webs in an alternating sequence. The separating walls are in a parallel, face-to-face relationship and are spaced from one another by a distance less than the expected smallest size of the tufts. The slots in one separating wall are staggered in a horizontal direction with respect to the slots in the other separating wall and the width of the slots is greater than the expected largest size of the tufts.
