ABSTRACT:
A printing press inking mechanism comprising a fountain roller dipped in a printing ink in an ink fountain, and a drawout roller movable alternately into and out of rolling engagement with the fountain roller and a first of a series of ink rollers for ink transfer from the former to the latter and then to a plate cylinder. The drawout roller when in rolling engagement with the first of the ink rollers can be revolved therewith and so can be automatically cleaned therewith clean of the printing ink by a solvent. The fountain roller has so far been left out of rotation, requiring manual cleaning. Thus a cleaning roller is additionally provided which is movable, at the time of the cleaning of the rollers, into rolling engagement with both the fountain roller and the drawout roller to transmit the rotation of the ink rollers to the fountain roller, so that the fountain roller can also be automatically cleaned with the other rollers.
