The cartridge for an inked ribbon comprises a casing having a magazine for housing the ribbon of the closed loop type and disposed in randomly distributed turns, and a pair of rollers for the feed movement of the ribbon. A re-inking pad is rotatable in the casing and an ink distribution roller co-operates with the pad for re-inking the ribbon. The distribution roller comprises a shaft having its ends projecting from the ends of the roller and housed for rotary and sliding movement in slots in the casing and the cover. The slots are rectilinear and have their axes co-planar with the shaft of the pad to permit movement of the roller away from and towards the pad. The distribution roller is held in contact against the pad by the tension applied to the ribbon by the rollers. The tension of the ribbon automatically regulates the contact pressure of the distribution roller against the re-inking pad and optimizes re-inking of the ribbon. |
