Abstract
This application relates to an apparatus and method for automated inspection of formed metal containers. More specifically, it pertains to the use of machine vision systems to identify and correlate manufacturing defects occurring in formed food and beverage containers to specific manufacturing paths or sources of origin (eg., body makers) used in the container forming process. The disclosed invention is enabled by the placement of a machine-readable code on specific portions of the can body during the forming process and the use of illumination exposure techniques.
