Abstract
A pallet (4) bearing a load of objects (5) disposed in horizontal layers formed of parallel rows aligned in a certain direction (Y) is raised step by step on a frame (1) by a lift (2, 3). A transfer arrangement (7) provided with claws (31) is mounted on a carriage (8). A control causes the claws to engage under each of the objects of a row so that this row is secured to the transfer arrangement, after which the row is placed on a conveyor (10) which then transfers it to another conveyor (11). This latter conveyor moves in the aforementioned direction and brings each object to the entry station (14) of a machine (15).
