ABSTRACT:
Apparatus for removing buildup of high viscosity printing inks from the edge of a doctor blade in an inking fountain used in a rotary printing press is disclosed. A moving cleaning web or sheet is supported in spaced relation to the edge of the doctor blade by a conducting blade whose position is adjustable both horizontally and vertically. Buildup of high viscosity ink at the edge of the doctor blade is eliminated as the built up particles of ink are picked up and carried away by the moving cleaning web or ink wiper which may be either an endless web or a disposable roll of material.
