ABSTRACT:
The present invention relates to an ink supplying device adapted for a rotary press used for printing news papers. More particularly, the present invention relates to an ink supplying device comprising an inking cylinder, an ink feeding means for feeding ink to the inking cylinder, and an ink temperature control means for controlling the temperature of the ink to be fed to the inking cylinder within the optimum range.
The temperature control means comprises a medium circulating unit including a medium chamber, a medium temperature detecting unit, a heater and a cooler; a heat exchanger; a pipe system for circulating between the medium circulating unit and the heat exchanger; and an ink temperature detecting unit.
The heat exchanger is preferably selected from plate type heat exchangers.
This system allows that the ink temperature is quickly adjusted to the optimum range for printing work and further always maintained within the optimum range during its printing work.
