ABSTRACT:
An ink return system for an inking fountain assembly in a rotary printing machine is disclosed. An ink return conduit assembly, which is comprised of inner and outer rigid telescoping ink return conduits, is supported by the inking unit. An inner end of one of the rigid conduits underlies an outlet port of an ink collecting trough and an outer end of the other of the conduits is placed above an ink receiving tank. Excess ink from the inking unit, which is collected in the ink collecting trough, flows through the ink return conduit to the receiving tank.
