Abstract
A can seam inspection apparatus. The apparatus has a pathway for a can and the pathway having an inlet and a pair of outlets. There is one outlet for can with a defective seam and another outlet for acceptable cans. A releasable holding device holds the cans as the cans move along the pathway. This holding device is rotated as they move along the pathway. The cans rotate with the holding device. The holding device can be released adjacent the inlet and the outlet. The can is inspected, preferably by a roller moving around the seam, as the can rotates. If the can is found defective then the inspection apparatus includes mechanisms to open the first outlet to allow rejection of the can. If the can is acceptable the can rolls over the first outlet to the second outlet. The equipment operates at high speed and with excellent accuracy. It can operate effectively in hostile environments.
