The system inspects gum with user-selectable tolerances for size, appearance, and other quality features.  Each machine outputs gum in a continuously moving line of product and packaging.  A fast, optimized inspection time is required to improve quality without reducing throughput.  The system includes intelligent scrap recovery, separating recoverable product from rejects.  A flat panel display shows immediate product results and images.
