Abstract

Method of optical inspection of closures on containers in which the outer edge of a closure is illuminated obliquely from above over the full circumference, and a photograph of the top side of the closure is made perpendicularly from above, and this photograph is used to detect the outer edge of the mouth, which appears brighter, and to check on the position of the cover logo relative to this edge of the mouth either directly or indirectly, and a signal is generated in the event an unacceptable eccentricity is found.
