Abstract: Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

Abstract: An apparatus and process for applying a coating material onto a substrate as a non-uniform layer of coating material, the method including providing a distribution manifold having a cavity and a plurality of dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction, and dispensing coating material from the dispensing outlets while simultaneously translating the plurality of dispensing outlets in a second direction non-parallel to the first direction. Using the process, coated articles having a useful non-uniform coating or coatings can be prepared, in particular self-adhesive vapor permeable air and moisture barrier membranes for use as architectural structure wraps.
