Webs include print patterns repeated at print pitches. The first web is intermittently fed at the print pitch of the first web by a first pair of feed rollers to a section. The second web is fed at the print pitch of the second web by a second pair of feed rollers to the section. The first web and the second web are fed in a superposed state by a downstream pair of feed rollers from the section. A first tension roller and a second tension roller engaging with the first web and the second web are biased by a biasing member via a linkage.

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.
