DEVICE AND METHOD FOR DETECTING A DEFECT IN A FINISH RING OF A GLASS

摘要

A device and method for detecting a defect in a finish ring of a glass article are described. The actual position of the finish ring is measured and enables a photographic device to be accurately positioned in relation to the finish ring, whereby the optical axis of the photographic device passes through the center of the finish ring. A sample of the finish ring is made and processed via an analyzing device configured so as to automatically detect an optical signature of the defect.
