Abstract: PROBLEM TO BE SOLVED: To improve productivity by unifying a double stack into a single stack structure which can travel at speed twice of stack speed and re-stacking packs before being presented to a cartoning device. SOLUTION: A pack forming device or a packaging apparatus 10 performs a final production process on cartons, boxes or other uniform product containers. A pack appears as a double stack 12 and is carried between a lower belt 16 and an upper belt 15. In addition, an end 20 of the pack 12 is visible and inspected by a camera. A top pack 22 on a leading stack 22 is unified by preventing an upper pack 22 from advancing in a static unifying device 24 by a bar or a curved face crossing a path of the upper pack 22. This pack is inspected on a main surface by a front pack camera 30 and inspected a side by a side camera 32. Then a continuous flow of inspected products is maintained.
