Abstract

A method of applying a coating material to a moving strip of substrate comprising the steps of: (a) providing a supply signal from a controller to a coating supply unit to control the supply of coating material from the coating supply unit through a liquid usage detector and a liquid meter unit and to a coater for application to the moving strip; (b) providing a measure signal from the liquid usage detector to the controller to measure the flow rate of coating material through the liquid usage detector; (c) providing a delivery control signal from the controller to the liquid meter unit to control the amount of coating material delivered from the coater to the moving strip; (d) providing a heating signal from the controller to the inline heater to control the heating of coating material within the inline heater; and (e) providing a dispense signal from the controller to the coater to dispense coating material from the coater for application to the moving strip. In a preferred embodiment, the method desirably also includes the steps of detecting the position and width of the moving strip and providing a position/width signal to the controller to control the positioning of the dispensing of coating material by the coater head. The method also may include the step of recovering excess coating material dispensed from the coater.
