Abstract: A conveyor system for conveying electrically conductive articles such as aluminum bottles or cans. The conveyor system comprises a plurality of coils below the top surface of an electromagnetic conveyor at a junction between an infeed conveyor and a discharge conveyor. The coils propagate electromagnetic flux waves that induce currents in the electrically conductive articles that force the articles to follow a conveying path from the infeed to the discharge conveyor. Dead spots on the electromagnetic conveyor can be eliminated by adjusting the coil drive waveforms. And a long electromagnetic conveyor driven by a train of narrow pulses is used to singulate electrically conductive articles.
