ABSTRACT:
The apparatus includes a frame and means for moving a container relative to the frame. A series of force exerting rollers are adjustably mounted on the frame and engagable with the container such that they are effective to exert a force on the crease line of the flap as the container is moved relative to the frame. In this manner, the crease is manipulated or worked such that the flap will remain in the closed position. Rollers are also provided for preventing deformation of the container surface adjacent the crease line as the force exerting rollers act thereon. Some of the force exerting rollers have a surface oriented at 45.degree. from the top of the container and thus act directly on the crease line. The deformation preventing rollers have a surface parallel to the surface of the container adjacent thereto. A force exerting roller may be combined with a deformation preventing roller to form a single roller having a flanged portion and a cylindrical portion. In addition, the rollers may be positioned along the path of movement of the container successively closer to the surface upon which the container is moved such that each exerts a progressively greater force on the container as it is moved.
