Abstract
A tractor feed for paper webs with margin perforation for use in printers of data processing systems in which endless bands support feed pins engagable with said perforations to effect paper transport toward, around and away from a platen. Upper and lower runs of the endless band and feed pins supported thereby are selectively adjustably movable into and out of paper guide slots to facilitate introduction and loading of the paper web. The band is movable by movable upper and lower guide rails which are controlled by an adjusting mechanism and by springs acting to spread said guide rails apart.
