A machine for erecting, filling and closing rectangular cartons, comprises a magazine for storing a plurality of flat folded cartons in a stack which has a bottom discharge opening for individual removal of each carton. A support bar located below the discharge opening defines a first station to which each carton in succession is moved past deflection means which effect a preliminary erection of the carton by deflecting side walls upwardly from the bottom. The shifting member is movable backwardly and forwardly over the support bar and has means for maintaining the carton in an upright erected condition while moving it and while it is being filled. A product stuffer includes a product magazine for storing a stack of individual products to be filled into the container which is located adjacent the first station and which includes a movable product support member carrying the lower portion of the stack which is movable away from the remaining portion of the stack to transport the lower portion away and to support the remaining portion.
