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.

Claim 1
Independent Claim
183 words
In a document processing machine, apparatus for urging documents against a registration fence while simultaneously driving said documents along a conveying path determined by said fence, said apparatus comprising: a housing frame; a registration fence secured to said frame; a deck secured to said frame for receiving said documents seriatim; a pair of cooperating rollers rotatably mounted on said frame, said rollers having crossed axes, one of said rollers being mounted in perpendicular relationship to said fence; means for driving said one roller, said one roller having an elastomeric covering with disk portions separated by grooves, said disk portions being radially segmented to thereby form individual petals, the other of said pair of rollers being resiliently biased against said one roller and oriented at an acute angle to said one roller, thereby exerting a normal force toward said one roller to provide resultant component frictional forces for causing lateral and longitudinal movement of said document along the fence, said one roller able to withstand said normal force and to permit said documents to move laterally regardless of the amount of said normal force.
