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 minimize the plug diameter variation between successively necked cans, the axial retracting movement of the slide roll is halted at a predetermined location via contact with a spacer to prevent further radial inward movement of the form roll which would otherwise occur as a result of only cam controlled form roll movement.
