Abstract
A tooling assembly for scoring a can end is provided. First and second opposing tool members cooperate to create a depression in the can end, and to form a scoreline within the depression. A conversion press for converting a can end shell into a can end, and a method for scoring a can end are also provided. The method includes engaging a first side of the can end with a score knife, supporting at least a portion of a second side of the can end with a score anvil, depressing the can end into a cavity of the score anvil to form the depression, and forming the scoreline within the depression. The depression and scoreline are formed substantially simultaneous within the same tool station of the conversion press. A sealant, which is applied to the scoreline, forms a pool within the depression, thereby completely covering the scoreline.
