A boxing apparatus erects packages that can be erected along a limited section of a conveyor, without having to erect them all at once, even with individual packages that are long in the feed direction. The boxing apparatus has a fourth conveyor belt that blocks the front of a line of incoming packages and exerts an upward force on the front package. The front package is raised up by this upward force, so the following package rides up onto the package in front, and the packages are erected successively. Consequently, even individual packages that are long in the feed direction can be erected at a limited section of a third conveyor belt.
