Abstract
The object of the invention is to provide an effective means of circulating inked ribbon by means of friction rollers into and out of a cartridge where it has been stored as a compact mass of ribbon folds. Means must be provided to prevent this mass of ribbon from being damaged or jammed when it leaves the rollers. This has been accomplished by introducing a movable stripper which does not frictionally engage the ribbon during its passage through friction rollers but which frictionally engages the ribbon after such passage to move the ribbon away from the friction rollers and thereby minimize scuffing and rubbing action between ribbon and friction rollers.
