The pinch rollers are in engagement with opposite sides of the monotrack guide rail. One of the pinch rollers is of a lower compression stiffness than the other pinch roller. The guide mechanism is coupled to a walking beam assembly wherein a pair of support rollers are mounted at opposite ends of a beam extending in the direction of movement of the conveyor, and the guide rail mechanism is coupled to the beam between the pair of support rollers.
