Apparatus for testing and emplacing flexible packages provided thereto from a form, fill and seal machine. The apparatus includes conveyor means for advancing the incoming packages to a weighing and leak-seal test station. A weight check is performed at such station by examining the initial peak displacement of a weighing platen at such station. If the weight test yields a satisfactory result, a fluid pressure driven ram is brought down upon the package and stopped at a fixed reaction pressure, the movement of the ram beyond a pre-set limit point being taken as an indication of pressure leak in the package and providing a defect signal. Signals indicative of rejection for weight or gas leak causes are stored in an appropriate memory, and the thus- identified defective package pushed off the conveyor at a downstream point. Upon a predetermined number of acceptable packages being transferred and assembled at a collection area adjacent the main conveyor, the group of acceptable packages are transferred and layered into a shipping case.
