Abstract:
1. A method for improving the uniformity of a liquid curtain in a coating system comprising a lip of a slide die wherein the lip includes a front surface on which a liquid composition flows by gravity, the method comprising the steps of: providing a ledge having a first, second, and third surface portion wherein the first surface portion is disposed intermediate the second and third surface portions, the first surface portion being substantially horizontal, the second surface portion being contiguous with the first surface portion and upwardly inclined away from the first surface portion, the third surface portion being contiguous with the first surface portion and downwardly inclined away from the first and second surface portions; supplying the liquid composition to the slide die; and positioning the ledge and lip relative to each other in a first orientation wherein the lip is disposed proximate the first surface portion whereby the liquid composition flows from the slide die onto the first surface portion, through a gap disposed between the lip and the first surface portion such that the liquid composition partially wets the back surface of the lip, and onto the third surface portion.
