ABSTRACT:
A device for shifting packs (P) of panels along the workpiece support table (L) of a sawing machine. The top surface of a stack of panels (P') comprises a pair of levers (1, 2) hingedly mounted on a motorized carriage (C). The first lower lever (1) frontally contacts the side of the pack (P) by its forward end defining a vertical pushing front (13) and has a lower jaw (17) acting on the underside of the edge of the pack (P), while a second, upper lever (2) forms, with its forward end (20, 21), the upper jaw acting on the top side of the edge of the pack (P). The second lever is actuated for gripping the edge of the pack between the two jaws (17, 20, 21). The lower jaw (17) can be moved from an operative position in which it projects forward with respect to the vertical pushing front of the first lever (1), whereby the shifting device is adapted to grip the edge of the pack (P), to an inoperative position in which it is retracted with respect to the vertical pushing front of the first lever (1), whereby the shifting device is adapted to act as a pusher which shifts the pack (P) of panels with a skimming action with respect to the underlying flat horizontal surface, without gripping the edge of the pack itself.
