Abstract
An improved flexible leader for use in conveying ink ribbon from a ribbon box to the print point of a printer or typewriter is disclosed. The leader is a U-shaped channel with top latches which protects the ribbon from operator contact and provides good ribbon tracking. Vertical raised ridges on the insides of the channel reduce frictional contact between the ribbon and the leader. The leader is easy to install.
