Abstract
Apparatus and method for forming a uniform fiber column in a chute feed (A) which includes an entrance opening (34) in a reserve section (30) of the chute at which an inclined air deflection vane (42) is pivoted for deflecting the incoming fiber-laden airflow downwardly in nonturbulent, uniform flow paths. A fiber column (F) with a level top surface (43) is provided along the entire length (L) of the reserve chute (40). An adjustable width throat (B) in the reserve chute compacts and shapes the fibers into a fiber column having a desired form avoiding fiber drag down the chute walls. The adjustable throat includes a pair of longitudinal movable wall elements (66, 68). The wall elements may be adjusted and fixed in position to provide a throat cross-section having a desired width (W) or shape depending on the type fiber being fed.
