<p>A gripping device comprising: first (17) and second (15) matable jaw members; a cylinder (10) adapted to reciprocate vertically means connecting the first jaw member to the cylinder such that, in operation, the cylinder and connecting means urge the first jaw member to open and close the jaws; means for maintaining the second jaw member in a fixed position relative to the cylinder; a fixed table (21) positioned beneath the jaw members, provided with at least one transverse groove (22); means for transporting a product downstream on the fixed table to locate it with its upstream or downstream edge overlying the transverse groove; means for advancing the cylinder downwardly with the jaws in the open position to enable the lower end of the second jaw member (15) to contact the product at its upstream or downstream end above the groove causing the product to tilt in the groove; means for activating the cylinder to close the jaws to grip the tilted product at its upper end; means for retracting the cylinder upwardly with the closed jaws gripping the product; and means for deactivating the cylinder to open the jaws to release the product. <IMAGE></p> |
