ABSTRACT:
Containers, such as batteries, battery cases and the like, are moved along a first conveyor to a leak testing station, above which is located an assembly having means matable over the openings in the top of the container. The container is supplied with air at a given pressure, and metering means notes pressure change. If the container does not leak, the container advances from the testing station along the conveyor. If a leak is detected, a reject means ejects the container transversely from the testing station along a second conveyor, thereby isolating leaky containers for further processing.
