ABSTRACT:
A sheet-feed tractor of the type that includes a belt with pins for advancing edge-perforated paper is provided with an extension on its web-retention door for mounting an idler roller that is used for friction feed of paper that does not have edge perforations. A drive roller is provided opposite the idler roller on a drive shaft that also is used to drive the belt containing the pins. As a consequence, paper located between the drive and idler rollers is advanced when the drive shaft is rotated.
