- 12 - RIBBON FEED APPARATUS Abstract of the Disclosure An apparatus is provided for employment of a double-width ribbon in a printing apparatus, in which a complete traverse of a ribbon extending between a ribbon supply spool and a ribbon take-up spool at different levels may be completed, utilizing one-half of the width of the ribbon in cooperative relation with a printing device, after which the ribbon and associated spools are removed from the printing apparatus, reversed and replaced, so that the unused portion of the width of the ribbon is placed in operative relationship with the printing device, and a second traverse of the ribbon in a printing operation may then be completed. The apparatus includes drive mechanism for driving one of the spools, brake mechanism for selectively braking the movement of at least one of the spools, ribbon diverter mechanism for controlling the path of the ribbon between the spools and for changing the path and inverting the top and bottom of the ribbon from one level to another, a guide for supporting the diverter mechanism for movement along a predetermined path, and resilient mechanism coacting with the guide and diverter mechanism to maintain proper tension in the ribbon as it is fed from one spool past the printing device to the other spool.
