<p>A can seam inspection apparatus. The apparatus has a pathway for a can (10). The pathway has an inlet (12) and a pair of outlets (14, 16). One outlet (14) is for cans with a defective seam and the other outlet (16) for acceptable cans. A releasable holding device holds the cans (10) as the cans move along the pathway. This holding device is rotated as it moves along the pathway. The cans (10) rotate with the holding device. The holding device can be released adjacent the inlet (10) and the outlets (14 and 16). The can (10) is inspected, preferably by a roller (92) moving around the seam, as the can (10) rotates. If the can (10) is found defective then the inspection apparatus includes mechanisms to open the first outlet (14) to allow rejection of the can. If the can is acceptable the can rolls over the first oulet (14) to the second outlet (16). The equipment operates at high speed and with excellent accuracy. It can operate effectively in hostile environments.</p> |
