ABSTRACT:
An ink fountain dividing key for use in an ink fountain of a rotary printing machine is disclosed. The ink fountain dividing key has a front face that is spaced from the peripheral surface of the ink fountain roller and which is curved with a radius of curvature the same as the radius of the ink fountain roller. A groove is formed on this curved front face of the key with the groove being supplied with compressed air at a pressure suitable to prevent ink flow from one side of the key to the other through the space between the key and the peripheral surface of the ink fountain roller.
