Abstract
A system is provided, in which the drive chain 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 or slip. 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 as well as by the amount of force provided by a biasing member. The threshold force depends upon the angle and the amount of biasing force.
