A document facing apparatus for reversing the face orientation of a document includes four substantially similar document folding modules, each having a document gripping and advancing portion and a folding portion. The gripping and advancing portion engages the document along a first longitudinal half portion, with substantially the other longitudinal half portion extending outwardly of the gripping and advancing portion, and advances the entire document through the folding module. The document folding portion engages the document along its other longitudinal half portion and folds the other longitudinal half portion of the document to a substantially 90° angle relative to its initial orientation upon entering the document folding portion. Four document folding modules may be aligned in a given sequence such that a document passing therethrough will have its face orientation reversed.
