ABSTRACT:
A method and apparatus is provided for detecting defective seams in cans having metal lids. The apparatus is mounted in cooperation with a conveyor to evaluate the cans being conveyed in a continuous operation. The apparatus includes a detecting device which has a pair of electrical contacts positioned to cooperate with a seam on the can. The electrical contacts are spaced apart a distance to contact a bulge in the seam which completes an electrical circuit between the contacts. A signal is then produced indicating a defective can, and the defective can is removed from the conveyor.
