ABSTRACT:
A conveyor system is provided and comprises an elongated frame having a plurality of rollers mounted to the frame in a spaced and parallel relationship so that the rollers define an elongated conveyor track along which a series of workpieces are transported. A plurality of work stations are defined at predetermined longitudinally spaced positions along the track while work stops associated with the frame selectively engage and hold the workpieces at the individual work stations. The rollers between the work stations are continuously rotatably driven at a constant speed while, conversely, a friction drive arrangement is used to rotatably drive the rollers at the work station. The friction drive permits the work station rollers to remain stationary when a workpiece is held at the work station.
