Abstract: A reversed can end ejector system for detecting and ejecting a can end in reverse orientation with respect to a moving stack of otherwise similarly aligned and nested can ends is disclosed. The system utilizes a reversed end extractor bar having a hook formed at a lower end thereof. The bar is supported above the stack with a support frame so that the hook is free to ride on a cylindrical exterior ridged surface of the stack. When a reversely oriented end is encountered, the hook is sized to drop by gravity into the peripheral gap formed between the reversed end and adjacent non-reversed end. The extractor bar is pivotally connected to a mounting bar which is in turn pivotally connected to the support frame whereupon further advancement of a reversed end with the stack during hooked engagement causes the reversed end to be lifted and removed from the stack via controlled rotation of the extractor bar relative to the mounting bar and then both as a unit relative to the suppport frame.
