ABSTRACT:
A machine for erecting flat, collapsed tubular cartons and for filling and sealing the erected cartons provides higher production rates without significantly increasing the cycle rate or the floor space required by the machine. A rotatable mandrel assembly rotates about a horizontal axis and has pairs of radially extending mandrels at equally spaced circumferential positions. The mandrel assembly is driven in a stepwise sequential manner to bring each pair of mandrels sequentially into alignment with a series of work stations. At a loading station, a two-stage loading assembly erects a pair of carton blanks and loads carton blanks onto the pair of mandrels. One carton blank is inserted directly onto a mandrel, while the other carton blank is advanced to an intermediate holding position for loading during the next operating cycle. At subsequent work stations the bottom ends of the carton blanks are formed and sealed. The pair of carton blanks with their bottom ends sealed are then transferred to a substantially horizontal track and are advanced together to subsequent work stations where they are filled and where the top ends are closed and sealed.
