Abstract
An inking unit for use in a rotary printing machine is disclosed. A plurality of endless belts are placed side by side along the surface of a driving roller. These belts transport a liquid medium such as printing ink or damping fluid along the surface of a covering of a cylinder in the direction of the longitudinal axis of the cylinder. The liquid medium is transported by the belts from a position of excess ink to a position of less ink thereby ensuring a uniform distribution of the liquid along the surface of the roller.
Claims3
An inking unit apparatus for use in transporting a liquid medium along the surface covering of a rotatable cylinder carrying the liquid medium in the direction of the longitudinal axis of the cylinder, said inking unit apparatus comprising:
- at least one driving roller;
- a plurality of guide pulleys rotatably positioned at a distance from said driving roller;
- a plurality of endless ink equalizing belts, each of said endless ink equalizing belts extending between said driving roller and one of said guide pulleys, each of said endless ink equalizing belts having an outer surface layer capable of accepting the liquid medium and being in contact with the cylinder carrying the liquid medium;
- and
- mobile transfer means contacting said outer surface layers of adjacent ones of said endless ink equalizing belts to transfer the liquid medium between said endless ink equalizing belts.
