ABSTRACT:
An apparatus for separating a first flexible lamina of predetermined thickness from a second lamina to which the first lamina is adhered along an edge (e.g., a pouch for use in an identification card) includes a channel having a thickness not substantially greater than the combined thickness of the laminae, an impeller for impelling the laminae together through the channel and out of the outlet end, a cutter adjacent the outlet of the channel positioned to contact the edge at which the two laminae are adhered adjacent the line of adhesion between the laminae, thus separating the laminae, and a wedge adjacent the cutter so that as the first and second laminae are separated by the cutter and impelled past the wedge, the two laminae pass on opposed sides of the wedge, thereby increasing the separation between the laminae.
