ABSTRACT:
Flat folded carton blanks with four end flaps are taken out of a carton magazine one by one by a takeoff mechanism. A carton blank thus taken out is delivered to a vacuum plate provided on the outer circumference of a rotary drum. While the carton blank is sucked to the vacuum plate and circularly transferred, it is knocked from the trailing side thereof by an unfolding guide so as to be set up. A flap, which is on the leading side in the direction of advance, of the carton unfolded to a cross-sectionally rectangular shape is bent outward by a tucker moving at a speed higher than that of the vacuum plate, and the other flaps are pressed at their inner surfaces against a fixed guide to also be bent outward.
