Abstract
A storable rack assembly to be used to drive a paper stop of a buckle-type sheet folding pan includes a perforate reversed crown extension spring attached at its outer end to the paper stop while the opposite end thereof is coiled within a housing. A rotatable sprocket located outside of the housing meshes with perforations in the reversed-crown extension spring to drive the spring and thereby move the paper stop. An indicator mechanism for indicating the amount of movement of the paper stop includes an indicator sprocket, which rotates with the rotatable sprocket and meshes with apertures in an indicator steel band. The storable rack assembly is mounted on a bias bar which, in turn, is pivotally mounted on the fold pan.
