Abstract
A first sheet panel is folded along a first fold line, and thereby a first folded part is formed in the first sheet panel. Subsequently, the first folded part is folded back along a second fold line, and thereby a folded-back part is formed in the first sheet panel. A corner cut device cuts a second sheet panel and the folded-back part to form corner cut parts. At this time, the corner cut device prevents the first folded part and a base part of the first sheet panel from being cut.
