Abstract
Apparatus and method for use with a flow packing machine for detecting and identifying the presence of metallic contaminants in bulk material loaded into a container is disclosed. The apparatus according to the invention includes a filler conduit for conducting the bulk material from the flow packing machine into the container. A metal detector senses the presence of metallic contaminants in the material being loaded into the container through the filter conduit and provides a detection signal indicative thereof. A spray gun or other marking device is supplied with an indelible fluid. The spray gun marks the exterior surface of the container in response to the detection signal.
