ABSTRACT:
The claw (2) is made up of a front part (3), moved vertically by a jack (31) and comprising a horizontal pressing plate (30) and a rear pressing plate (34), and a rear part (4) moved horizontally via another jack (46) and comprising a lower pressing plate (40) suspended by a pivot pin (42) from a stirrup-piece (41), a further jack (47 l) acting upon the rearward end (40A) of the lower pressing plate in order to raise and lower the front end (40B) thereof. When the rear pressing plate is lowered opposite a stack of blanks to be grasped, a slight depression (52) is created, whereby it is then possible to slip the front end of the lower pressing plate under the stack in order grasp it by raising the lower pressing plate and pressing the stack against the upper pressing plate. The claw is intended to be integrated in a depalletizer feeding a packing machine, particularly a machine making packs in the tobacco industry, especially packs of cigarettes. A plurality of such claws may be mounted side by side for grasping a whole row of stacks of blanks simultaneously. A sweeper device (36) mounted on each rear pressing plate allows the entire top layer of rows of stacks to be pushed back when the depalletizer detects that the row to be grasped is the first one of the layer, in order to form a ledge necessary for creating the aforementioned depression.
