ABSTRACT:
A conveyor assembly18that detects bags that leak. The assembly18includes a first conveyor24that operates in unison with a second conveyor29. The conveyors24and29confine the bags in chambers, with the bags being engaged by pressure assemblies50so that the bags that leak are reduced in volume. The bags are engaged at a downstream position and at an upstream position by detection devices44that provide a signal indicative of the volume of each bag. These signals are compared to thereby identify bags that leak.
