Abstract
A can end is provided that has a three part chuck wall. The first chuck wall has an angle of 20 degrees to 35 degrees as measured from an axis perpendicular to the can end. The second chuck wall has an angle of 4 degrees to 27 degrees as measured from the axis. The third chuck wall has an angle of 18 degrees to 32 degrees as measured from the axis. Tooling adapted to manufacture the can end is also provided. Additionally, a seaming chuck is provided that has a recess that is adapted to avoid contact with radii of curvature along the chuck wall during seaming of the can end to a can body.
