Abstract
Apparatus for sequentially removing articles from a stack of nested articles and for controlling their movement to a location remote from the attack. The apparatus is particularly suited for denesting and feeding large multiple cell cartons such as eighteen cell cartons to a conveyor for subsequent printing. The cartons are placed in a vertical stack and the stack of nested cartons is supported by a set of rotary brushes on opposite sides at the bottom of the stack. The cartons are preseparated and sequentially fed by a second set of rotary brushes from the bottom of the stack to a denesting station. The height of the stack of cartons at the denesting station is sensed by a photoelectric eye for controlling the rotation of the sets of brushes and the feed of cartons to the denesting station. A pair of counter-rotating feed screws having multiple operating sections denest the cartons at the denesting station and sequentially feed them to a conveyor.
