High Efficiency Cartridge-Enclosed Fabric Ribbon
This single cartridge, one-way, continuous drive ribbon device permits more
efficient use of the ribbon ink and potentially increases the ribbon usage without
increasing the ribbon length.
Fig. 1 shows schematically the spool arrangement for the ribbon. Ribbon
feed direction is clockwise, and the print line is between spools A and B. The
ribbon path is from spool A to B, B to C, C to D, from D back around C and
feeding from the center of spool C to E with a 180OE twist (Moebius strip effect),
and from E to A where the path repeats.
Spools C and D are tilted at a slight angle. This allows spool D and E to be
mounted one above the other even though spool D is tilted and spool E is not.
Spools C and D are the main reservoir of ribbon and contain many winds of
Fig. 2 indicates the path of the ribbon between spools A and B.
The ribbon runs at an angle R between the spools. This allows full
and more efficient utilization of the entire width of the ribbon as
the printhead traverses and prints. As the ribbon is advanced, the
printhead (not shown) prints from top to bottom of the ribbon as well
as laterally. The 180OE twist in the ribbon between spools C and E
allows more efficient and complete usage of the ribbon ink as the
ribbon is fed.
The single cartridge enclosure for the ribbon is shown in Fig. 3. Since the
cartridge surrounds the printhead and carrier, carrier travel is the determining
factor in the width of...
