Abstract

A method and apparatus for spin flow necking-in a D&I can is disclosed wherein an externally located free spinning form roll is moved radially inward and axially against the outside wall of the open end of a trimmed can. A spring-loaded interior support slide roll moves under the forming force of the form roll as the latter slides along a conical forming surface of a second free roll mounted axially inwardly adjacent the slide roll. To prevent damage to the metal caused by excessive pressure contact between the form and slide rolls, the slide roll is axially retracted via a cam ring which initially contacts the form roll during radially inward necking movement.
