Zusammenfassung:	A first sheet panel 1 is folded along a first fold line 10, and thereby a first folded part 13 is formed in the first sheet panel 1. Subsequently, the first folded part 13 is folded back along a second fold line, and thereby a folded-back part 22 is formed in the first sheet panel 1. A corner cut device 37 cuts a second sheet panel 2 and the folded-back part 22 to form corner cut parts. At this time, the corner cut device 37 prevents the first folded part 13 and a base part 28 of the first sheet panel 1 from being cut
