An apparatus and method for forming an erected carton from a blank for cartons having non-traditional configurations is disclosed herein. Such non-traditional configurations may include beveled edge cartons and eight-sided cartons. The apparatus includes rolling means for breaking a first set of crease lines on the blank, force exertion means for breaking a second set of crease lines on the blank, and maintenance means for maintaining the shape of en erected carton. The present invention also includes a mandrel configured to substantially match the side configuration of a carton such as a beveled edge carton.

Carton forming device

A filling system of a packaging machine is set forth that reduces the mixing of product and air during the filling of the container with a flowable material such as low fat milk. The fill pipe of the filling system has an elliptical cross-section which provides for a reduced velocity of the flowable material entering the container while allowing for an increased production time of the packaging machine. The fill system is especially adopted to fill containers having a rectangular cross-section. Connected to the fill pipe is a nozzle with flaps designed to substantially conform and engage with the sidewalls of a container. When the flaps are urged to an open position, the mixing of air and product is inhibited as the flowable material is dispensed into the container through the nozzle and as a moving mechanism is operated to relatively move the container and nozzle from a first to a second position. The fill pipe has an elongate body, an inlet end and an outlet end. The inlet end is in flow communication with the fill pump and may have a circular cross-section. The outlet end is in flow communication with the nozzle and has an elliptical cross-section. The cross-section of the elongate body gradually transforms from a circular cross-section at the inlet end to an elliptical cross-section at the outlet end.
