摘要

Perfection in cartridges for inked ribbons of typewriters; whose cartridge comprises a container of the tape and a pair of rollers for advancing the tape, of which one is the drive roller, which can be operated from the outside, and the other is the pressure roller, which tightens the tape against the motor roller, characterized in that the cartridge can be mounted on a machine comprising a pair of bolts, one of which is the motor bolt and the other the contrast bolt, and by a spring that serves to reciprocally bring the bolts of the torque, serving the pair of rollers of the cartridge to get in contact with the pair of bolts of the machine, so that the motor roller is dragged by the motor pin and the pressure roller comes in contact with the contrast pin and in this way at least the rollers of the cartridge can move freely radially in a corresponding seat of the container, and carries a part that serves to move at least one bolt away from the pair so that the spring is allowed to tighten the pressure roller against the motor roller when the pair of rollers of the cartridge is inserted in the pair of bolts of the machine.
