Abstract

A gauge profile apparatus (100) includes a gauge profile system (104) and a lap count system (106) for determining an average three-dimensional profile over the length of a sheet coil (10). The gauge profile system (104) includes a lap profile measuring device (112) which will make a distance determination between top and bottom surfaces for the sheet coil (10). The lap count system (106) includes a distance sensor (288) and camera (290) for determining the average thickness of the sheet coil (10). A second embodiment of the gauge profile system (400) is also provided, which utilizes a PDA (404), an ultrasonic tester (406) and a string encoder (432).
