Abstract
A conveyor assembly 18 that detects bags that leak. The assembly 18 includes a first conveyor 24 that operates in unison with a second conveyor 29. The conveyors 24 and 29 confine the bags in chambers, with the bags being engaged by pressure assemblies 50 so that the bags that leak are reduced in volume. The bags are engaged at a downstream position and at an upstream position by detection devices 44 that provide a signal indicative of the volume of each bag. These signals are compared to thereby identify bags that leak.
