ABSTRACT:
A method for making a brush seal includes weaving a single-layer bristle assemblage having two spaced-apart cloth segments joined together by an unwoven section wherein the two cloth segments and the unwoven section share a common first group of warp bristles and wherein the two cloth segments have different groups of weft bristles. The method further includes the step of cutting generally across the unwoven section of the first group of bristles to create free ends. The brush seal so made is useful, for example, to generally seal a leakage gap in a gas path of a gas turbine.
