A method and apparatus for forming a box with gusset corners folded against outside of box, and blank forced into forming chamber

摘要

A method and an apparatus for forming a box is disclosed. The first step of the method is to form a blank into a partially-erected box that has a base (3'), upright side walls (5'), upright end walls (7'), gusset corners (9') that are outside the interior of the box and side flaps (11') or end flaps (15') that extend upwardly from the side walls (5') or the end walls (7'). Adhesive material is then applied to the outer surface of the side walls (5') or the end walls (7') and the side flaps (11') or the end flaps (15') are folded outwardly and downwardly so that the gusset corners (9') are sandwiched between the folded down side flaps (11') and the side walls (5') or between the folded down end flaps (15') and the end walls (7'). The blank is initially forced into a forming chamber.
