ABSTRACT:
An apparatus for controlling the lateral alignment of a belt arranged to move in a predetermined path includes a first roll arranged to support a portion of the belt passing thereover. The first roll has first and second ends. A first centering assembly for the belt is located adjacent the first roll. The first centering assembly includes a first rotating member located adjacent a first end of the first roll and a second rotating member located adjacent a second end of the first roll. The first and second rotating members urge the belt to an equilibrium position on the first roll. In one embodiment, the first and second rotating members are rollers which may either be tapered or crowned. In a second embodiment, the rotating members are driven rollers which rotate towards each other. In a third embodiment, the two rotating members are endless tracking belts which rotate towards each other.
