ABSTRACT:
Apparatus shown for feeding documents of selected width singly from a stack in alignment without buckling. Guides are provided at either side of a bin for holding a stack of documents. One guide is fixed and the other adjustable in order that the bin may hold stacks having documents of selected widths. A shingler (combing wheel) shingles the documents forward to a separator/restraint station, which feeds the documents singly. In order to properly align the sheets for separation, the adjustable guide is connected by an adjustment device to the shingler wheel. The adjustment device (e.g., cable and pulley) is arranged to move the shingler wheel half the distance the adjustable guide is moved. This keeps the shingler wheel centered with respect to the documents. The separator/restraint station is positioned so as to always be to the side of the shingler wheel towards the fixed guide to abut each separated sheet against an alignment edge thereof for precise alignment thereof.
