Abstract
A chute feed having a vertically extending chute for collecting and densifying fiber therein, the chute being formed by a plurality of fixed, imperforate walls, and a perforated wall portion mounted adjacent the lower end of the chute for oscillating movement about a horizontal pivot shaft. Pressurized air is forced downwardly through the collected fibers in the chute and is discharged through the perforated wall portion, thereby densifying the fiber. The oscillating movement of the perforated wall portion results in the upper and lower ends thereof being alternately moved toward and away from the collected fiber to alternately compress such fibers and then release such fibers from the holding effect of the air passing through the perforated wall.
