ABSTRACT:
A jet coating apparatus and method for applying coating mix onto a moving web in a noncontacting manner in ambient pressure. The apparatus includes an upper lip placed close to the web, a lower lip situated in the vicinity of the upper lip and arranged essentially on the trailing side relative to the moving direction of the web. The slot orifice bounding surface of the upper lip and the slot orifice bounding surface of the lower lip form a slot orifice suited for feeding the coating mix onto the web. In the slot orifice, at least the directional vector along the slot orifice surface of the lower lip has a vector component opposite to the tangential velocity vector of the web.
