Abstract

A portable separating device which can be taken from stack to stack. At a desired stack, it is placed onto and supported by the top of the stack. It has opposed, vertically staggered, stack-engaging pads so located that one engages an edges of the top panel, whereas the other engages the edges of one or more of the lower panels. A mechanism moves the pads toward one another to apply shearing force to the top panel to shift it together with the device relative to the remainder of the stack. The grip is then released and the device lifted off. Then the top panel is removed, and the device applied to the next lower panel and the separating step repeated.
