Abstract
A method and apparatus for making banded smoking article wrappers is provided. The apparatus includes a cylindrical rotating applicator that has alternating regions of mesh material and regions of solid material on its outside surface. The applicator allows repetitive patterns of additional slurry to be applied to a continuous web of paper so that the basis weight of the paper is repetitively increased. Such paper, when incorporated into a smoking article, modifies the burn rate characteristics of the article.
