Web and sheet paper feed mechanism for printers

摘要

A universal paper transport mechanism for feeding both continuous form and single sheet paper to a printer includes pin belt tractors longitudinally displaceable along a guide bar transversed to the direction of movement of the paper, the tractor is driven from a laterally positioned motor. The tractor drive transport mechanism is pivotable from a horizontal position to a vertical position and attachable and detachable guiding elements are provided for use with single sheet paper, and are affixable to the tractor transport mechanism in an area adjacent and above a printing station area. The guiding elements are substantially symmetrical relative to one another and can be attached to the guide strip of the tractor transport mechanism on which the individual pin belt tractor assemblies are guided.
