<p>A pressure testing system (10) for determining the presence of defective containers is disclosed. Detected defective containers may thereafter be transported to an ejector station and ejected physically from their respective supporting tray. The pressure testing station (12) is provided with an array of pressure testing heads which are moveable reciprocally towards and away from the containers while supported in their tray. Each of the pressure testing heads thus makes sealing contact with the rim of an individual respective one of the containers (C) supported in the tray (T). The ejector station (14) is provided with an array of ejector assemblies equal in number of the number of the containers crossmachine plane. If a container is determined to be defective (i.e., will not achieve and/or maintain in a predetermined pressure condition when a pressurizing fluid, such as pressurized air, is introduced into the container at the pressure testing station), a controller will issue a signal corresponding to that one of the ejector assemblies which is in registry with the detected defective container, forcing it downwardly through the tray.</p> |
