Abstract
Abstract A shroud is positioned near the exit area of a stuffed ribbon cartridge for a typewriter or similar machine to prevent more than one strand of a ribbon from being withdrawn from the storage chamber of the cartridge at a time. The shroud is a ridge on the floor of the storage chamber with the distance from the top of the ridge to the ceiling less than the width of the ribbon. The shroud is formed around the exit area in an arc shaped so that the single strand of ribbon being withdrawn from the storage chamber will cross the shroud substantially at right angles to the shroud from any direction that it is pulled from inside the storage chamber.
