Abstract:
A method for depositing a uniform coating having a predetermined thickness on a substrate, said method comprising the steps of:providing substantially linear relative motion of a coating device with respect to said substrate, wherein said linear relative motion step causes said coating device to traverse a surface of said substrate to be coated; dispensing a coating material at a controlled rate from said dispensing device, wherein dispensing of said coating material from said dispensing device provides coating material sufficient to entirely cover said surface of said substrate to be coated in a single iteration of said linear relative motion; and capturing coating material dispensed from said coating device unnecessary for coating said surface of said substrate to be coated with said predetermined thickness, wherein said capturing step comprises the step of: interfacing a capturing surface with said substrate to present a substantially continuous composite surface with said surface of said substrate to be coated during at least a portion of said relative linear motion step; and separating portions of said capturing surface, wherein ones of said portions of said surface may interface with said surface to be coated while other ones of said portions of said capturing surface may be uninterfaced from said surface of said substrate to be coated.
