ABSTRACT:
An Apparatus for separating and advancing documents includes a moving element for frictionally engaging and advancing one of the documents along a path, and a stationary element for frictionally engaging and halting the advance of the remainder of the documents. The moving element and the stationary element each include a plurality of belts and are disposed in relative juxtaposition whereby the one document is gripped between the moving element and the stationary element and advanced along the path under the influence of the moving element. The moving element and the stationary element contact the first and second surfaces, respectively, of the one document via the respective belts to provide a column strength to the one document over a substantial surface area of the document as the one document advances through the apparatus, thereby preventing portions of the one document from being crimped between the moving element and the stationary element.
