Abstract
A method and apparatus of applying a coating to a substrate is provided. A liquid resin is introduced into a first region at a predetermined pressure. The liquid resin is maintained within a first pressure range in the first region. Next, the flow of the resin from the first region to a second region is controlled so as to bring the resin from the first pressure range to a second pressure range, the pressures in the second pressure range being lower than the pressures in the first pressure range. The liquid resin is then applied at a pressure within the second pressure range to the substrate at a third region adjacent the second region.
