Multiple layer coating method

摘要

A plurality of simultaneously applied coating fluids is coated on a substrate by moving the substrate along a path through a coating station. A plurality of flowing layers of coating fluid is formed in face-to-face contact with each other to form a composite layer. This composite layer flows at a speed that is sufficiently high to form a continuous flowing composite layer jet to the substrate surface for the coating width regardless of the direction of flow of the fluid jet.
