A device (100) for feeding blanks (99) to a packaging machine (M) , includes at least one rotating group (G) for picking up flat folded carton blanks from the bottom of a stack (94) of blanks (99), in a picking up position (P), by means of picking up vacuum means (7) supported by the group (G) . Then, the picked up folded blanks are erected into box-like configurations (A) in an erecting position (K) . Then, the group (G) feeds the blanks (99) to an inlet station (98) of the machine (M) , to place them one by one in the station (98) in a placing position (ID) . The group (G) includes one first cinematic series (Cl) for determining the movement of the picking up vacuum cups (7) along a closed path (T) , extending between the picking up position (P) and the placing position (ID) . A second cinematic series (C2) controls and maintains constant the orientation of the picking up vacuum cups (7, V) . |
