ABSTRACT:
A document feed array comprising a pinch-roll mounted to rotate about its center to engage documents, being mounted on a cantilever-arm pivoted at a point distal from the roll-center and including an elastomeric sleeve which, alone, couples the arm to its pivot point (in operation), the sleeve comprising high-damping, durable elastomeric material adapted to accommodate thickness anomalies in the documents, yet to maximize driving contact therewith.
