Abstract
A process and apparatus for working an edge portion of a flange positioned on an open end of a container to prepare the flange for end-piece attachment by shaping such edge portion and improving flange uniformity, and, if desired, configuring the flange into a desired angular orientation. In one embodiment a plurality of working rollers are positioned radially outward from the edge of the flange and a mechanism is used to force at least portions of the flange toward the rollers. When at least a portion of the flange engages with at least one of the rollers as the rollers are rotated relative to and about the flange, flange uniformity is improved as the flange edge is shaped by such roller. In the event the flange continues to be forced toward the working rollers, remaining portions of the flange may approach and possibly contact the rollers to be shaped and worked thereby while the outward radial movement of the initial contacting edge portion is restrained, thereby further improving flange uniformity.
