Abstract: A carton-packaging machine (10) which causes progressive erection of carton sleeves from a supply of blanks (11) in a magazine (19), the partly erected blanks being loaded with product (24, 25) and then being closed in the form of a sleeve around the product. An endless conveyor (12) moves the blank through a blank supply station (14), an erection station (15), a product loading stations (16), a folding station (17) and a discharge stations (18), and a suction device (20) cooperates with the magazine (19) in order to draw individual blanks in flat form into the path of travel of the conveyor (12) for engagement thereby. A shaping device (21) at the erection station (15) forms each blank into U-shaped form and which is then advanced by the conveyor to the loading station (16) for loading with product (24, 25).
