ABSTRACT:
Apparatus and method for detecting glass fragments within closed filled jars on a production line. A plurality of jars is conveyed in serial fashion past an inspection station. Prior to arrival at the inspection station the jars are tilted by an acute angle of approximately 45.degree. to define a lowermost portion of the jar bottom into which glass fragments and the like settle. A light source illuminates this lowermost portion at the inspection station, and a television camera is precisely focused on the lowermost portion. The camera relays a signal for producing a magnified image on a monitor so that an operator can divert jars containing foreign matter out of the line.
