An apparatus for measuring sidewall thickness of a container (22) includes a support (32, 34) coupled to a first motor (36) for holding the container in stationary position while rotating the container about its axis. A gauge mechanism (110, 122) engages opposed interior and exterior points on the sidewall of the container, and provides an electrical signal as a function of sidewall thickness between such points. A second motor (90) is coupled to the gauge mechanism for moving the gauge mechanism in the direction of the container axis. A controller (152) is coupled to the first and second motors, and is responsive to the electrical signal from the gauge mechanism for obtaining and storing a three-dimensional data map of sidewall thickness at increments of motion of both the first and second motors. Thus, there is provided thickness data related to angular orientation and axial position, which can then be analyzed to identify specific problems associated with container manufacture. <IMAGE> |
