ABSTRACT:
A powered paper transport for use in association with platen machines, such as typewriters and printers, utilizing perforated margin paper. The transport mechanism is attachable and detachable adjacent the platen, is driven from the platen and is displaceable relative to the platen to provide a desired bias force on the paper between the platen and the tractor drive of the transport. Adjustable stop means are provided to limit the displaceability.
