Ribbon Guides For Minimizing Adhesion
The present structure provides ribbon guides which project from partitioned
ribbon guide rollers and act to prevent ribbon and particularly adhesive correction
ribbon from sticking to the rollers.
With reference to the drawing, ribbon 10 is transported through the driving
action of roller sets 12 and 13 which respectively rotate in the direction shown
around their respective axes 15 and 16. The rollers are spaced from each other
to permit separated contact surfaces between rollers and ribbon. Stationary
protruding guide fingers 14 facilitate the release of the ribbon from the rollers.
The present structure minimizes the adhesive action of ribbon to rollers
resulting from the adhesive character of some of the coating on the ribbon,
particularly after the ribbon has been struck by impact means in carrying out a
printing or typing operation. By facilitating the release, the structure minimizes
the likelihood of ribbon misfeeding or breakage due to adhesion of the ribbon to
the transport roller. The design also enhances ribbon stacking into stuffer boxes
when such stuffer box ribbon supply structures are utilized.
