APPARATUS AND METHOD FOR ERECTING CONTAINERS

摘要

Apparatus and method wherein a three-piece container is erected by carrying separate end panels with a mandrel into contact with a main body blank and moving the blank and end panels with the mandrel through a container-erecting station where end panel-engaging flaps along opposite end edges of the bottom and side walls of the blank are brought into contact with the outer surface of the end panels. Corner-strengthening flaps are also provided along opposite side edges of the end panels, and means are provided adjacent the path of mandrel travel to fold the latter flaps simultaneously inwardly prior to contact of the end panels with the body blank to permit such end panel flaps to engage the inner surface of the side walls of the container. Means are provided to permit the end panels to be moved in two stages by the mandrel from their initial positioning station first to an initial rest position, then to their finally erected position in the container.
