ABSTRACT:
A method of and apparatus for determining whether kegs, which are to be cleaned and filled on a bottling plant production line, have physical distortions which may prevent cleaning and/or filling and/or emptying. The testing of the barrels is accomplished by capturing images of the ends and processing the data commensurate with the captured images to identify radial distortion. Axial distortion, which may accompany any radial distortion, is determined by measuring the distances between plural points on the keg and a reference plane to which the keg axis would, under normal conditions, be transverse.
