ABSTRACT:
A method and apparatus for coating a liquid coating composition to a moving web in which air entrained on the web is replaced by a gas having a higher solubility than air in the liquid coating composition. The moving web is exposed to the gas immediately before it arrives at a die through which the liquid coating composition is applied to the web. A vacuum system may be used to remove the air from the web prior to its exposure to the gas.
