ABSTRACT:
A liquid coating supply system for a printing press blanket coater is disclosed. The system includes a vessel for holding a supply of the liquid coating material, the holding tray for holding a portion of the liquid coating material for pick up by a feed roller, a first liquid transfer means for transfering the liquid coating material from the supply vessel to the holding tray and a second liquid transfer means for transfering the liquid coating material from the holding tray to the supply vessel. The first liquid transfer means has an adjustable flow valve for regulating the liquid flow from that transfer means, and a supply pump between the supply vessel and the adjustable flow valve for withdrawing the coating material from the supply vessel and for forcing the material through the valve under a pressure which is dependent upon the adjustment of the flow valve. A pressure responsive means between the pump and the adjustable valve conducts liquid flowing from the pump back to the supply vessel when the pressure between the pump and the adjustable valve exceeds a predetermined value.
