Abstract
A process and apparatus for resizing the throat of a cylindrical container and simultaneously reforming a preformed flange on an open end of such container. In one embodiment, the throat of the container is resized by applying an outward force to the throat to increase the diameter thereof. Moreover, the preformed flange is forced radially outward. However, the outward radial movement of at least a portion of an outer edge of the preformed flange is restrained during such resizing. As a result, at least portions of the preformed flange flex between the throat and the restrained portion of the outer edge. These flexed portions project to differing degrees and at least a portion of this projecting flexure is maintained after the reforming process to improve flange uniformity.
