<p>Apparatus for separating the front and back walls (34,36) of an envelope (24). The apparatus includes a supporting frame; a device mounted on the supporting frame for holding an envelope having a back wall (36), a front wall (34), and a flap (30) extending from the back wall but not contiguous with the back wall; and an orbital claw assembly mounted in the supporting frame. The claw assembly includes a claw (54,56) movable in an orbit which positions the tip of the claw at an appropriate time between the front and back walls of the envelope and thereafter further movement of the claw in the orbit causes the claw to separate the front wall from the back wall of the envelope.</p> |
