Abstract

The drawings show a cartridge for a roll of typewriter or other printer ribbon molded in two parts from any flexible resilient plastic. Cover 1 has a depending, resilient brake-spring arm 3. Cartridge body 5 has a generally immobile brake post 7 on its outer wall and a resilient tension-spring arm 9 at the ribbon exit area near the post 7. In operation, the ribbon moves arm 9 and arm 9 encounters lower ledge 11 of brake arm 3 to release the brake.
