Abstract
An ink metering system for a rotating ink roll having a shaft journalled in the frame of a inking system includes two doctor blades and a mechanism for supporting the doctor blades on the shaft of the ink roll so that the doctor blades contact the ink roll under uniform pressure independent of movement between the ink roll and the frame. The arrangement also includes a mechanism for adjusting the pressure of the doctor blades and for sealing the system. The doctor blade is composed of polytetrafluoroethylene-polyphenylene sulfide ceramic resin containing graphite fibers. The doctor blade includes a number of laminated sheets of this material in which a majority of the sheets include fibers oriented in the machine direction and at least one sheet includes fibers oriented perpendicular to the machine direction.
