ABSTRACT:
Disclosed is an assembly for threading a ribbon, preferably an erase ribbon through an impact printer such as a typewriter. One end of the ribbon is stored at a ribbon storage means, while the other end of the ribbon has a tab fastened thereto. The longitudinal dimension of the tab is perpendicular to the longitudinal dimension of the ribbon and the tab contains a frangible portion which is used for finger engagement during the threading operation. The ribbon take-up reel contains a slot in one of the flanges thereof such that the ribbon tab may be inserted into the slot after the ribbon has been threaded through the printer. The frangible portion is then separated from the ribbon and discarded.
