  • Automatic blanket wash system
    Patent number: 4686902
    Abstract: The present invention provides an automatic blanket wash system that recirculates a separable mix of water and solvent. The mix is selectively applied to the blanket cylinders by closing a pressure valve in the recirculation system return line and selectively opening valves to spray bars at the blankets. The pressure valve closing causes a pressure build up in the system for the spraying of the mix onto the blankets.
