ABSTRACT:
Method and apparatus for peeling an image media-laminate to remove a throw-away layer from a keeper layer. The laminate is fed through a nip defined by upper and lower rolls and then the laminate is bent upwardly about a surface on the upper roll by an upwardly moving bar. One side of the bent laminate opposite the bar is held by vacuum adjacent a free edge of the laminate and then the bar is lowered during which a spring element on the bar deflects the free edge of the laminate to separate the layers due to differences in their stiffness. The lowering of the bar permits the keeper layer to descend as it separates from the throw-away layer which is released from the vacuum and continuously peeled by take-away rollers.
