ABSTRACT:
Method and apparatus for forming can ends is disclosed wherein ends are blank from sheet material and formed in a die in which the completed end is formed and removed from the die at a vertical position below the blanking position. Formation and removal of the end beneath the cut line enables better control of the ends after forming. Vacuum is applied to the end underside to positively seat the end against lower die forming elements as the lower elements raise the end to the level of an ejection slot where pressurized air blows the air from between the dies. An automatic lubrication circuit for properly lubricating seal members forming pneumatic cushions for resiliently biasing the various die members is also disclosed.
