Abstract: A number of cases are stored horizontally in a stack in a magazine. A bottom upper-inner flap of a flat folded case is folded downward to open the case by a flap-folding member while the case is being lifted from a magazine station to a flap-folding station, and while attracted to and held by a suction cup. The case is opened during this lifting and folding step. Once the bottom upper-inner flap has been folded downward, it comes into the space between the bottom outer flaps. The bottom upper-inner flap, which has been folded downward, pushes the left outer flap during the lifting operation. As the case is lifted higher and higher, both outer side flaps are opened simultaneously. The case is therefore gradually opened, during lifting, thereby forming a hollow cylindrical case. The remianing bottom flaps are closed and then sealed.

Abstract: In a method for affixing a ribbon to a bag containing rolls etc. the bag is continuously fed to a predetermined position. A tie material is continuously fed such that the tie material is close to the bag, is able to tie up the open top of the bag, and then is severed for a specific length. Also, the ribbon is continuously and longitudinally fed along the bag to the open top thereof and severed for a specific length. A tie piece severed from the tie material is wound around the open top to tie up the open top together with the ribbon and to affix the ribbon to the bag.
