Abstract: A re-inking device is fitted to a cartridge for an inked ribbon. The cartridge comprises a magazine housing the ribbon which is of the closed loop type and which is disposed in randomly distributed loops, and a pair of rollers for the unidirectional feed movement of the ribbon. The re-inking device comprises an ink reservoir or inker, an ink metering wick and a spring. The pair of rollers comprises two toothed wheels and the inker is disposed in a housing adjacent to the wheels. The ink metering wick comprises a bundle of capillary fibres and is disposed between the inker and the wheel. The spring presses on the metering wick to hold the fibres at one end in constant contact with the outside surface of the wheel. The crests of the teeth of the wheels are of a rounded section and the inker is of a parallelepipedic shape, is of polyester fibres with external co-extrusion and contains an amount of ink such as to occupy only half the volume of the inker.

Abstract: 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.
