Carton handling machine

A carton handling machine particularly suited for use in erecting cartons from collapsed, articulated blanks and presenting the erected carton to a loading station. The machine is characterized by a carton erecting station at which cartons are erected from collapsed, articulated blanks, a carton loading station having a fixed loading plane within which the opening of each erected carton is presented for carton packing purposes, and a carton advancing unit for simultaneously ejecting packed cartons from the carton loading station and advancing thereto cartons erected at the erecting station. The features of the invention include a readily dajustable support structure for accommodating cartons of various practical dimensions, without requiring an alteration of the position of the loading station, and a fluidic control circuit for dictating the sequence of the carton handling operations performed by the machine.
