Abstract: A stack of folded cardboard boxes (5, 6) is arranged in a magazine (1). Each folded cardboard box (5, 6) has a plane of main extension (7) and two parallel side edges (9, 10). The folded cardboard boxes (5, 6) arrive in the stack in a direction substantially perpendicular to the plane of main extension (7). The two parallel side edges (9, 10) of the first folded cardboard box (5) in the stack are first contacted and supported by a first stop (11) and by a second stop (12). The first folded cardboard box (5) is then conveyed in the direction toward the second stop (12) within the plane of main extension (7) until it enters an opening (18) being located in the region of the second stop (12) and it gets totally free from contact to the first stop (11) to be exclusively supported by the opening (18) and by the second stop (12).
