ABSTRACT:
An apparatus and method for erecting a carton having laminated corner structures. A multi-sectioned corner flap is folded progressively between an outer guide in the form of a longitudinal row of rollers and a spiraling row of conical rollers that accurately pinches a bent corner edge of the corner flap structure against the end panel to which it is joined in the carton blank. Surface-to-surface contact between the glued portions of the corner flap and the end panel is prevented until the folding action has been accurately completed.
