Abstract
A spout is attached to a wall of an article, such as a paperboard container, by pushing a stem of a spout longitudinally through a pre-formed hole in the article and against an inclined face of a flare tool so that a portion of the stem is bent laterally outwardly and into the path of a staking tool. The staking tool is displaced so that the face thereof bends a laterally outer section of the bent portion against the wall of the article while leaving a laterally inner section of the bent portion spaced longitudinally from the wall.
