Abstract

Systems, apparatuses, and methods for forming a Bliss-type container having main portion with side and bottom flaps and a side support portion. Systems can include a mandrel movably mounted on a path, a hopper providing the side support portion, a feeder providing the main portion, and a folding assembly configured to fold the side flaps over the support portion. The systems may further include a plurality of plows and compression plates for bending side panels of the main portion, the side support portion, and the bottom flaps over the mandrel. Methods can include moving a mandrel forward along a path inside a machine, engaging the side support portion on a first side of the mandrel, and engaging a bottom panel of the main portion on a front of the mandrel such that an edge of the support portion is aligned against said bottom panel. Side panels of the main portion may be bent over opposing sides of the mandrel which are generally perpendicular to the first side of the mandrel. After the side panels are bent, the side flaps may be bent over the first side of the mandrel by a plurality of folding members having extended and retracted positions. Apparatuses can include a folding member on a frame having an opening for receiving a mandrel. The folding member may have a portion movable in a direction generally orthogonal to a direction of movement of the mandrel, and may be configured to fold the side flaps between about 30 to 90 degrees towards the side support portion.
