A carton blank support member is mounted above a traveling carton blank in a folder gluer machine. The support member is cyclicly driven between an inoperative position above the carton blank to an operative position engaging the top surface of the blank adjacent a score line formed in the blank. The score line defines a flap which is folded upwardly when the support member is in engagement with the top surface of the carton blank to form a side wall of the carton. The support member prevents the flap from buckling during the folding operation, especially when recycled paperboard is used as the carton blank.
