ABSTRACT:
An apparatus for cleaning dust from the cells of a honeycomb core part includes an upper air knife for blowing a narrow jet of air downwardly through the honeycomb core cells as the part is being carried on a conveyor belt through an exhaust hood. A pair of upwardly aimed air knives below the conveyor belt blow two narrow jets of air on both sides of the upper air knife upwardly through the honeycomb core. The part is held down on the conveyor belt against the lifting force of the two air jets from the two lower air knives by a floating hold-down mechanism, which is adjustably counterbalanced to control the amount of hold-down force it exerts on the honeycomb core part. The upper air knife is mounted on a counterbalance system that enables it to ride above and blow downwardly through the hold-down mechanism without exerting significant force on the honeycomb core part. The dust removed from the part is entrained in an airstream drawn through the exhaust hood and is removed from the air stream in a cyclone separator.
