Abstract
A cartridge for an endless inked ribbon for printing office machines comprises a container in which are disposed separating elements which define a storage zone. An endless inked ribbon is disposed in loops and is distributed at random in the storage zone. The inked ribbon passes from a slit to the exterior of the storage zone and through one aperture to the exterior of the container. A section of the inked ribbon is twisted through 180.degree. to form a Mobius loop, by guide elements which localize the twisted section in a zone of the container outside the storage zone. The inked ribbon passes back into a container through a second aperture and returns to the interior of the storage zone through an opening thereof. At least one curved wall, adjacent to the slit, defines an housing for receiving any loop which have escaped from the slit for preventing a plurality of loops of the ribbon emerging simultaneously from the storage zone.
