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.

Method and apparatus for necking containers

A modular system for producing triple-necked open ended containers includes three substantially identical necking modules each having the same frame and identical rotatable turrets which have a plurality of identical necking stations around the periphery. Each necking station includes an annular necking die and a platform and punch which are cam-operated to move towards and away from each other and are maintained in engagement with the cams by pressurized fluid. Each necking station also has a container pressurizing means in the form of an annular chamber which acts as a holding chamber prior to transmitting the pressurized fluid into the container.

Method and apparatus for necking and flanging containers

A method and apparatus for producing a reducing neck and a peripheral flange on a free peripheral edge portion of a cylindrical container body is disclosed herein. The apparatus consists of a fixed frame having a waxing station, a necking station, and a flanging station defined thereon. The containers are fed from a source in a synchronized fashion along a path with the axis of the cylindrical bodies of the containers extending vertically and are moved past the waxing station where the cans are rotated relative to fixed brushes to apply lubricant to the outer surface of the peripheral free edge portion. The reduced neck on the container is produced by supporting the containers on a bottom member that is carried on the periphery of a turret and an upper member having an annular die with the bottom member being cammed towards and away from the die to produce the reducing neck of the container. The flanging of the container is accomplished with a flanging turret having a plurality of flanging assemblies on the periphery thereof each of which consists of an upper member that is rotated about a fixed axis in a sleeve on the turret and a lower member that is reciprocated towards and away from the upper member by cam means.
