Abstract
A conveyor system is provided, in which the drive chain which drives products along the conveyor has features that permit control of the threshold driving force that will be reached before the chain's carrier rollers begin to rotate to permit accumulation of product on the conveyor. The threshold driving force is controlled by friction members which are located between split portions of the carrier rollers and by the angle of the outer surface of the carrier rollers. The steeper the angle, the greater the threshold force.
