  • Patent number: 5813267
    Abstract: Methods and apparatus for improving the concentricity and reducing the flange width variation of a die-necked container body are disclosed. A piloted pad is inserted into the dome at the bottom of the can, either as part of the flanging operation or as part of a die necking operation, or both. The insertion of the pilot and pad orients the can body relative to the necker or flanger so that the open end of the can remains concentric with the main body diameter as forming operations progress. Preferably, when used as part of a die necker, the pusher pad connected to the pilot is spring loaded. By spring-loading the pusher pad, accidental engagement between the raised section that extends into the dome is prohibited, and each can is more readily ejected and transferred.
