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.

Abstract: An improved hydraulically actuated take-up device, for use with conveying members subject to both sudden accelerations and variations in length resulting from changes in thermal loading, wherein a portion of the member is displaced to maintain a predetermined tension therein. Minor corrections are effected gradually through action of a hydraulic damper while a relief valve prevents tension build-up beyond a predetermined limit. The action of the take-up may be reversed to relieve the tension on the member to facilitate periodic maintenance and adjustment.
