ABSTRACT:
A document alignment system includes a plurality of drive rolls (42, 44) operative to drive documents one by one along a feed path, and a plurality of alignment rolls (100) spaced apart along the feed path with their axes perpendicular to those of the drive rolls (42,44) and operative to move a document (124) transversely to the feed path so as to bring a long edge of the document (124) into parallel abutting contact with a reference surface (72). When the alignment rolls are operative the drive rolls (42) are inoperative and out of contact with the document (124). Each alignment roll (100) is arranged to cooperate with a spring biased rotatably mounted ball (112) whereby in the course of an alignment operation the document (124) is gripped resiliently between the alignment rolls (100) and the cooperating balls (112).
