A folding and tucker-tacker station operates upon a flat bottom end closure of a packaging sleeve, which closure comprises four panels (6, 8, 9) and (17) and a minor panel (12) protruding from the outermost edge of the panel (8). The station comprises a mounting (30) to (33) supporting three jaws (39c), (42) and (43) oscillatable transversely of the sleeve axis A for folding inwards the respective panels (8), (9), and (7), and a jaw (40) displaceable along, but not transversely of, the axis A for folding inwards the panel (6). The jaw (39c) has a recess (39d) for receiving the minor panel (12). The jaw (40) is disposed after the jaw (39)c along the path of a mandrel (48) transporting the sleeve. <IMAGE> |
