ABSTRACT:
A die necking method and apparatus for producing a smooth tapered wall between the container side wall and a reduced diameter neck includes a plurality of rotatable necking turrets that each have a plurality of identical necking substations each having a necking die. The necking dies in the respective turrets have an internal configuration to produce a necked-in portion on the container which has a first arcuate segment integral with the container side wall and a second arcuate segment integral with the reduced diameter neck. The necking substations also have a floating form control element that engages the inner surface of the container to control the portion of the container to be necked. The necked-in portion is reformed in each succeeding turret by dies to produce a smooth tapered wall between the arcuate segments.
