Abstract
A cartridge for an inked ribbon for printing machines, in particular wire printers, comprises a container and a pair of rollers for the feeding of the ribbon. The container comprises a storage zone, in which an inked ribbon is disposed in loops and is distributed at random, and a guide zone which surrounds the printing head of the machine. The guide zone comprises a series of ribs which twists a section of the inked ribbon through 180.degree. to form a Mobius loop. The rollers are free to move radially in corresponding seats of the container and are able to engage a pair of pins of the machine. One pin is a motor pin and rotates one of the rollers, and the other pin is a pressure pin which engages the other roller and is urged by a spring against the motor pin. The pressure pin causes the ribbon to be nipped between the two rollers to be fed by the motor pin.
