Abstract
PURPOSE:To automatically adjust volume of moistening water in accordance with change in revolution of a printing machine, by making a selecting circuit conduct switching operations by a relative signal between a detected revolution and a set value of a printing machine, and also, by controlling a drive motor for a group of water supply rollers by the signal. CONSTITUTION:A detector 28 detects revolution of a printing machine and puts out a signal of the detected revolution to a comparator 29. A setting apparatus 30, in which a prescribed revolution that is to become a reference for comparison is appropriately set, puts out a signal of the set revolution to the comparator 29. The comparator 29 compares these two signals and puts out to a changeover switch 27a a relative signal in accordance with the difference between them. The switch 27a selects a circuit for a variable resistor 27b or a variable resistor 27c accordance with the relative signal and controls revolution of a rotary drive motor 25 for a group of water supply rollers to a high speed or a low speed.
