发明名称 Method and apparatus for coating webs
摘要 Method and apparatus for coating a moving web with a multilayer liquid composition. The liquid composition is flowed by gravity down an inclined surface having slots for feeding each layer onto the inclined surface. A lip at the lowermost end of the inclined surface changes the direction of flow of the composition to a generally upward direction generally aligned with the direction of movement of the web. The angle between the upward direction of liquid flow at the end of the lip and the tangent to the web at the point of initial contact of the liquid composition and the web is between about 95 degrees and 175 degrees.
