Abstract
A method for minimizing waste resulting from defects caused at the edges of a coating on a substrate which was applied to the substrate by a slide coater. A first fluid flows through the first slot main portion at a first flow rate and through the first slot end portions at flow rates which differ from the first flow rate. A second fluid flows through a second slot onto a second slide surface positioned relative to the first slide surface and oriented such that the second coating fluid flows from the second slide surface onto the first coating fluid.
