ABSTRACT:
A modification of conventional case packing equipment for forming rectangular containers from knocked-down-flat (KDF) precursors allows formation of non-rectangular containers having one or more oblique wall panels, e.g., an octagonal container. As part of a conveyor line operation, a ram head assembly is advanceable into a rectangular tube erected from a KDF container precusor. The ram head assembly includes a pair of plows which are movable outwardly from a base of the ram head assembly and into engagement with opposing interior sides of the rectangular tube such that oblique corner wall panels are positively formed along score lines provided in the precursor. In addition to forming the oblique wall panels, the plows provide pressing surfaces for facilitating adhesive securement of the container closure flaps while the plow maintains the oblique wall panels in a proper orientation. Once the closure flaps are secured, the container shape is stabilized, the plows are retracted out of engagement with the container walls, and the ram head assembly is retracted from the resultant container.
