Abstract
A machine and method for separation of nested articles such as trays. Nested articles of the type that do not separate from one another under the influence of gravity alone are stacked in vertical nesting relation to one another. Plural blade members are movably mounted about the periphery of the tray members. In a first embodiment, the blade members move horizontally and vertically in a novel sequence to dislodge one tray from the lowermost end of the stack during each cycle of the operation. In a second embodiment, the blade members are pivotally mounted.
