Then, the first pushing unit 66, the second pushing unit 63, and the fourth pushing unit 65 are reset, and the carton folding machine 6 conveys the folded carton toward the capper with the third pushing unit 64 pressing the four sheet portions 84, and the capper adheres the three sheet portions 83 of the folded carton with an adhesive tape while the carton is moving.

And finally, the carton is conveyed by the sealing machine to move towards the bag turning machine 7, and the carton is clamped by the bag turning machine 7 and leaves the packaging production line.
