  • a carbon-ribbon cartridge of the aforesaid type is known in which the carbon ribbon is unwound from the feed spool with the aid of a first driving roller carried by an arm pivoted to the machine and adjacent the feed spool. This roller is held in resilient Contact with the ribbon against a pressure roller rotatably mounted in the cartridge. After the ribbon has been passed through the two apertures. it is guided over a second driving roller synchronous with the first and is collected on the take-up spool, which is rotated in turn by an independent mechanism. Owing to the presence of the pressure roller and the second driving roller in the cartridge. this cartridge is rather complicated and the cost of production is rather high. Moreover. since the first driving roller is carried by the machine and the pressure roller is carried by the cartridge. it is difficult to ensure parallelism between the two rollers. In the absence of this parallelism ⁇ the limited thickness of the carbon ribbon causes imperfect contact between the first roller and the ribbon. with the risk of breakage or of the ribbon slackening at the printing point.
  • the object of the present invention is to produce a carbon-ribbon cartridge in which the advance or feed of the ribbon can be effected by a pair of rollers. namely a driving roller and a pressure roller. ofthe machine. and which is of relatively low cost and which can be mounted securely' and simply on the machine.
