ABSTRACT:
A round open end container is supported and held on a turntable by a chuck. The edge of the container is guided and supported by rollers on roller heads mounted on brackets of stanchions positioned on opposite sides of the container. The brackets are movable vertically on the stanchions and the stanchions are movable radially relative to the turntable for positioning the rollers in supporting engagement with the edge of the container. A robot arm carries a C-shaped frame with opposing arms movable over the edge of the container between the rollers. Non-contact sensors are mounted on the arms of the C-shaped frame and are movable with the arms to predetermined vertical positions on opposite sides of the container wall for measuring the thickness of the wall at predetermined positions provided by rotation of the turntable.
