Title: METHOD AND APPARATUS FOR FORMING ARTICLES WITH NON-UNIFORMLY PATTERNED COATINGS
Abstract:
A process for applying a coating material onto a substrate as a non-uniform patterned layer of coating material, the method including providing a first distribution manifold having a cavity and a first multiplicity of dispensing outlets in fluid communication with the cavity, providing a second distribution manifold having a cavity and a second multiplicity of dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction, dispensing a first coating material from the first dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction, and dispensing a second coating material from the second dispensing outlets while maintaining the relative motion and simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction. Useful non-uniformly patterned coated articles can be prepared using the process.
