  • Flexible leader
    Patent number: 4339211
    Abstract: An improved flexible leader particularly suited for use in conveying the ink ribbon from a ribbon cartridge to the print point of a printing machine or typewriter is disclosed. Preferably, the leader is formed as an integral member having discontinuities therein defining bending points at which said leader is flexible. The leader can be flexed in only one direction, whereby the inked surface of a typing ribbon is never in contact with said leader, thus preserving its integrity.
