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 the use of a picking up vacuum device (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 kinematic series (C1) 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 kinematic series (C2) controls and maintains constant the orientation of the picking up vacuum cups (7, V).
