ABSTRACT:
A rigid airfoil surface and the exposed portion of the bottom sheet of a stack of flexible sheets in a magazine, form opposite passage walls of a venturi flow passage into which a flow of air is directed from a nozzle member. Collapse of the passage wall formed by the flexible bottom sheet is induced by the static suction pressure created at the throat of the venturi passage resulting in deflection of the exposed portion and separation of the bottom sheet from the stack in preparation for withdrawal by a gripper mechanism.
