Ribbon print track reinking with a roll system

Abstract From the Canadian patent

The specification teaches an apparatus for selectively reinking an endless ribbon in that portion of the ribbon known as the ribbon print track. The ribbon print track is created in an endless ribbon by the repeated striking of the ribbon by a print mechanism thereby deforming the ribbon and depleting it of ink. Reinking the entire ribbon uses more ink than is necessary. Reinking only the print track extends the life of the ribbon by selectively using the available supply of ink. The apparatus described herein achieves this result by use of an ink reservoir which supplies ink to a drive roller which, through a rotating pinching movement in cooperation with another roller, advances a ribbon …
