Abstract
Disclosed is a tool measuring device for measuring the size of tools used for making aluminum can bodies. The tool measuring device utilizes an LED measurement carriage having a central opening so that the LED measurement carriage passes over and around the tools. An LED linear beam is generated by LED linear arrays so that the tools cast a shadow on optical photodetector linear arrays. The distance between the transition points from light to dark on the optical photodetector linear arrays is measured to provide a highly accurate measurement of the size of various portions of the tools.
