Abstract: A device for applying top sheets on palletised loads, including at least one support for at least one palletised load, of the feeding means of top sheets (C) to be applied on the palletised loads, suitable to unwind at least one film reel (B) from which a plurality of such sheets (C) can be obtained, and at least one applicator member suitable to place, one by one, the top sheets (C) obtained from the reel (B), over the top of respective palletised loads. The applicator member includes at least one robotic arm, having at least one operating end, and at least one winding and unwinding member, associated with such operating end; the winding and unwinding member is able to wrap the sheet (C), taken from the reel (B), on a wrapping surface to take a substantially tube-shaped configuration, and then to unwind it over the top of the palletised load.
