1. A method of making an article, the method comprising:
simultaneously expelling a first precursor liquid of a first pressure-sensitive adhesive through a first set of multiple, laterally-spaced-apart openings in a coating die and simultaneously expelling a second precursor coating liquid of a second pressure-sensitive adhesive through a second set of multiple, laterally-spaced-apart openings in the same coating die,
wherein the openings of the first set and the openings of the second set are arranged in a generally alternating pattern with each other so that generally-alternating streams of the first and second precursor liquids are expelled therefrom and are deposited onto a surface of a substrate that is continuously moving past the coating die; allowing, for at least selected laterally-adjacent streams of the first and second precursor liquids, a lateral edge of the deposited first precursor liquid to laterally displace a lateral edge of the deposited second precursor liquid at the surface of the substrate, and, solidifying the first precursor liquid into the first pressure-sensitive adhesive and solidifying the second precursor liquid into the second pressure-sensitive adhesive, thereby forming generally alternating stripes of the first and second pressure-sensitive adhesives on the substrate,
wherein at least for selected stripes, the lateral displacing of a lateral edge of the second precursor liquid by a lateral edge of the first precursor liquid at the surface of the substrate causes a lateral edge portion of the first pressure-sensitive adhesive stripe to inwardly underlie, and to be in contact with, a lateral edge portion of a laterally-adjacent second pressure-sensitive adhesive stripe, and causes a substrate-side lateral width of the first pressure-sensitive adhesive stripe to be greater than an opposite-side lateral width of the first pressure-sensitive adhesive stripe by a factor of at least about 1.2. |
