A method and apparatus (1) for driving take-up elements (7) for palletizable load units (4), which are intended to effect cycles of movement each including at least a first and a second horizontal movement in opposite directions from each other, with a vertical movement in between. These movements are driven so as to follow each other without intermediate stoppages and with a continuous and substantially harmonic variation of the velocity and acceleration of the take-up elements (7). The apparatus (1) includes a linkage (10, 12) interposed between the take-up elements (7) and the motor (13) for driving their horizontal movement, and cam means (24, 25) driven by the motor (13) for driving the vertical movement. |
