An apparatus for making liquid-tight cartons from T-shaped blanks comprises means for folding a blank into a tubular body member having a pair of outwardly extending end closure panels (112, 114), means for transferring the thus folded blank into a support mandrel (402) fixed to a rotatable arbor (408), a member (432) for sealing the tubular body member along one side, jaws (442, 444) for infolding flange portions at one end of the body member and a roller (446) for folding an end closure panel (112) over the infolded flange portions during movement of the mandrel from the position at which side sealing and infolding of the blank occurs, to a position at which the end closure panel is sealed to the infolded flange portions by a sealing member (450). <IMAGE> |
