The present invention provides an apparatus for shaping/embossing thin-walled work pieces, and is particularly apt for realizing complex and non-uniform shapes/designs in cylindrical metal container bodies. In one application, at least one pressurized fluid stream is ejected directly against one side of container body sidewall with a configured surface provided on the other side of the container body sidewall to achieve the desired shaping/embossing. At least one of the pressurized fluid stream and configured surface may be disposed for rotational and/or longitudinal motion. Such driven motion can be utilized to achieve progressive helical working of a cylindrical metal container body, thereby yielding the desired shaping/embossing.

[ What is claimed is:] [1.] A metal container shaping apparatus comprising:a shape-defining means having at least one configured surface defined using at least two separable die members positionable adjacent to a metal, thin sidewall of a drawn and ironed container body having a longitudinal extent; andspray means for directing a pressurized fluid stream against a selected portion of said metal thin sidewall of said container body to force said selected portion toward at least one of said at least two die members of said shape-defining means, to provide local working of at least said selected portion into a predetermined configuration between said pressurized fluid stream and said at least one of said at least two die members and in which said spray means and said container body move relative to each other in a direction along said longitudinal extent during said local working, with at least portions of said spray means being inside said metal container body during at least some of the time said selected portion is shaped into said predetermined configuration.
