<p>Improvement to an apparatus (18) for singulating respective documents (14) fed thereto, the apparatus comprising first document feeding structure (40) including at least two first belts (42) and first structure for moving the first belts downstream relative to a path of travel in vertically spaced first belt runs, and second document feeding structure (80), adjacent the first document feeding structure, including at least one second belt and second structure for moving the second belt upstream relative to the path of travel in a second belt run. The improvement is to the second document feeding structure and comprises a first section (86) including an upstream end and a downstream end, the upstream end being pivotally mounted to a frame member, the first section also including at least two outboard endless belts (82) therearound and second structure for moving the outboard belts upstream relative to a path of travel in vertically spaced second belt runs; and a second section (88) having at least two inboard endless belts (84) therearound. The second section is pivotably mounted at one end to the first section. There is structure for coupling movement of the outboard belts of the first section to movement of the inboard belts of the second section for driving the inboard belts of the second section upstream relative to a path of travel in vertically spaced second section belt runs; and structure for resiliently urging the second section belt runs into interleaving relationship with the first belt runs, and for resiliently urging the downstream end of the first section belt runs towards the first belt runs. The urging structure enables the first and second sections to laterally flexed about the coupling structure in response to the documents fed thereto. <IMAGE></p> |
