ABSTRACT:
The present invention provides a novel extension apparatus and method for providing a selectively adjustable conveying path for sheet articles between sheet processing apparatuses. The extension apparatus includes a base bracket with a pair of rotatably movable spring-loaded bracket arms attached to a shaft extending therethrough. A pair of bracket arm rollers are attached to each of the bracket arms. An extension plate is positioned above and slidably movable on the base bracket, and a pair of rotatable extension rollers are rotatably attached to a shaft extending through the extension plate such that slidable movement of the extension plate simultaneously and identically moves the extension rollers. A pair of rear rollers are utilized and are operatively aligned with an extension roller and a pair of the bracket arm rollers. A pair of belts extend at least partially around and operatively engage one of the rear rollers, one of the extension rollers, and a pair of the bracket arm rollers of one of the bracket arms. The belts have an upper reach section and a lower reach section between the rear rollers and the extension rollers, and the upper reach section of the belts form a conveying path for advancement of sheet articles while the bracket arm rollers engage each belt in the lower reach section.
