Abstract
Flap folding device of a wrapping machine. Side folding guides approach side flaps to hit a hitting part against the closed side faces of a wrapped body part of a content or volume, thereby pressing a wrapped body part, near the base end of the side flaps that face the closed side faces, against the closed side faces. Subsequently, the middle part of each of the side folding guides makes a quarter turn while tracing a corner continued to the closed side faces,. Therefore, the base ends of the side flaps are folded along the corners while being pulled toward the forward end thereof, and, at the same time, are pressed by folding parts against the open sides, through the entire length, from the base end to the forward end, of the side flaps.
