ABSTRACT:
Typing ribbons stored in cartridges are reinked by the use of an apparatus having a plurality of drive devices arranged to pull the ribbon through the reinking mechanism and return the ribbon to the cartridge without placing stress on the cartridge case or rewinding mechanism. The apparatus includes a bracket for securely mounting the cartridge with the ribbon threaded over a self-inking drum. A drive system is provided for rotating the inking drum and pulling the ribbon by a drive capstan to maintain a taut condition. A variable speed motor is included for returning the ribbon to the cartridge through its reloading mechanism. Sensors and an electrical control circuit are provided for automatically stopping the reinking process at its completion or if a defect in the ribbon is detected.
