Abstract (en)

Side folding guides 1 approach side flaps A2 to hit a hitting part 1a against closed side faces B2, B2 of a wrapped body of a content B, thereby pressing a body wrapping part A7 near the base end of side flaps A2 facing the closed side faces B2, B2 against the closed side faces B2, B2; and subsequently the middle part of the side folding guides 1 make a quarter turn while tracing a corner B3 continued to the closed sides B2, B2, and therefore the base end of the side flaps A2 are folded along the corners B3 while being pulled toward the forward end thereof, and, at the same time, are pressed by folding parts 1c against the open sides B1, B1 through the entire length from the base end to forward end of the side flaps A2 .
