Abstract

Inked ribbon 1 in a stuffer box cartridge 2 can be stored with a reduced driving force by mounting the drive pinion and spring-loaded idler so as to insure that the contact force between the rollers is not significantly increased or decreased during changes in the compaction forces. This is accomplished by locating idler roller 4 at the end of an arm 5 supported on pivot 6, as illustrated in the figure. Pivot 6 is placed opposite the resultant force A caused by the drive pinion forces, frictional component of ribbon force against idler 4, and the packing forces due to compressing the ribbon. As a result of locating pivot 6 opposite the resultant of these forces, the contact force transmitted to the idler is approximately the same as the spring force.
