Abstract
An envelope making machine includes a printer for printing material on the envelope blanks as they are being formed into envelopes in the machine. The printer has printing modules which include an impression cylinder, a plate or type cylinder, an anilox roll and a fountain roll. The fountain roll is positioned adjacent to and rotates in a direction opposite to the anilox roll and upon rotation transfers a film of ink to the surface of the anilox roll. A distributor or doctor blade is positioned below the anilox roll and has a blade edge portion that is approximately in juxtaposition with a lower quadrant of the anilox roll and faces the direction of rotation of the anilox roll to control and distribute the film of ink on the surface of the anilox roll. An adjustment device is provided to adjust the thickness of the film of ink on the anilox roll. The adjustment device is operable to make adjustments in the ink film thickness while the machine is operating.
