ABSTRACT:
In a document processing machine, apparatus for urging documents against a registration fence while simultaneously driving the documents along a conveying path determined by the fence. The apparatus includes a housing frame, a registration fence secured to the frame, a deck secured to the frame for receiving the documents seriatim, a pair of cooperating rollers rotatably mounted on the frame, the rollers having crossed axes, one of the rollers being mounted in perpendicular relationship to the fence, and capability for driving the one roller. The one roller includes an elastomeric covering having disk portions separated by grooves the disk portions being radially segmented to thereby form individual petals. The other of the pair of rollers is resiliently biased against the one roller, thereby exerting a normal force acting toward the one roller to provide resultant component frictional forces for causing lateral and longitudinal movement of the document along the fence.
