Abstract
Apparatus and method for applying a high volatility liquid to a moving web to form a coating on the web. The coating liquid is applied to the web through an extrusion-type or slide-type hopper covered by a hood which collects evaporated gas from the applied solvent at a region at which a solid-, liquid-, and gas-phase interface of the coating liquid is formed. The collected gas is utilized to suppress further gas evaporation from the three-phase interface thereby preventing the formation of stripe-like defects due to undesirable solidification of the forming liquid.
