Method and apparatus for evenly coating a moving web of material with a predetermined amount of a liquid and characterized by simplicity of design, uniformity of application of the liquid and accurate control of the amount of the liquid applied, as follows. Mechanisms are provided for supplying and feeding a web of material in a longitudinal path of travel at a predetermined speed. A coating roll is positioned for transverse rotating contact with one surface of the traveling web of material and includes a covering of soft, uniformly and highly absorbent material for receiving and uniformly absorbing the coating liquid and for transferring and uniformly coating the traveling web with the liquid. An open top pan is provided for continuously receiving the coating liquid therein. The coating roll rotates within the pan for contacting and continuously absorbing all of the coating liquid within the pan above the level of the coating roll. Mechanisms are provided for continuously metering coating liquid to the pan in a predetermined amount related to the speed of travel of the web of material and the amount of liquid to be coated thereon for continuous absorption by the coating roll and continuous coating of the web with all of the predetermined amount of metered liquid.
