ABSTRACT:
A blank is folded to form a box by pressing it into a jig. End and side panels of the blank, along with supplemental panels at the corners, are lifted relative to a floor panel by folding surfaces of the jig. The side panels are lifted first and supplemental end panels are thus positioned inside the end panels. The blank may also include supplemental side panels that are folded outwardly and backwardly by corner guides of the jig.
