Abstract
In a cartridge for an endless typewriter ribbon, a fresh ribbon is stored in the cartridge with a substantial length of ribbon wound in a convolute around a roller. When the cartridge is mounted in a printing apparatus, the ribbon is drawn from the cartridge, exhausting the convolute. When the cartridge is fully mounted in position in the printer, a single path of ribbon extends into the cartridge and through an opening along a chord of the roller and out from the cartridge. A brake is provided to limit motion of the roller so as to preclude premature unwinding of the convolute and to limit oscillation of the roller during operation of the printer. With the normal operating path of the ribbon extending through the chord-oriented slot of the roller, ribbon can readily be rewound onto the roller upon removal of the cartridge from the printer.
