ABSTRACT:
A machine for forming a variety of different sturdy, stackable three-part fiberboard containers having a depth dimension greater than their width dimension, and which are suitable for holding bags filled with liquid. The machine includes a slidable, removable mandrel which cycles between a fiberboard hopper area and a container forming compression area. Each of two side bins provides a fiberboard end panel which comes into contact with independently slidable edge picks on the mandrel. Just before the mandrel cycles forward, the edge picks push the fiberboard end panels forward where they are bent by the action of two folding elements. Meanwhile, a fiberboard body matt is brought into position in front of the retracted mandrel from an overhead feed unit. Adhesive material is sprayed onto selected parts of the body matt as it is placed into position in front of the mandrel. As the mandrel cycles forward, the body matt is bent over into a C-shape and the now-folded end panels are pushed into close association with the middle of the body matt. A set of guides and plows bends the body matt flaps over the end panels forming sturdy corners. The compression plates loosely surround the bent fiberboard pieces in order to avoid early adhesion until the mandrel is fully extended forward bringing the fiberboard pieces into proper position. Once positioned, the compression plates collapse around the fiberboard pieces forming a finished container. The finished container is then displaced as the machine cycles back to form another container.
