  • Tape tensioning mechanism
    Patent number: 4273454
    Abstract: An improved ribbon tensioning means is disclosed in which a spring-loaded gear rack is in engagement with a gear wheel formed on a spool of tape to be unwound. The gear rack is provided with sufficient travel in the direction opposite to that of the spring force that the teeth thereon can be disengaged from those on the gear wheel if the wheel is rotated a sufficient distance, thus constantly providing tension to a tape or ribbon wound on the spool.
