ABSTRACT For use in business machines, one-piece holders or cartridges are described for holding spools or cores carrying inked ribbons or coated film ribbons. Each cartridge, although a single permanently integral unit, enables each spool or core to be located in operative positions removed and replaced, the spool or core being located in the cartridge by flanges at its opposite ends, and at least one of these flanges being sufficiently resilient to permit the spool or core to be removed. In one example, a neck at one end of a core can be moved along a slot in one flange to locate a shallow journal in a recess at the end of the slot, the opposite end of the core being located by a bearing hole in the other flange. In another example, a circular flange formed at the end of each spool is journalled in a shallow depression in one cartridge flange in which it is retained by a resilient cartridge flange bearing on the opposite end of the spool. The spools or cores are arranged so that they can be positively driven by the machine mechanism. - 1 -
