Abstract
A method and apparatus for destacking trays from a nest, in which the nest when inverted, bears against a suction plate covering the lowermost tray to form a closed chamber. The nest is clamped and negative pressure is applied to the closed chamber through the suction plate which is withdrawn carrying the adhering lowermost tray with it. The negative pressure is then released and the tray falls away from the suction plate.
