The brush seal includes a plurality of bristles located in grooves along opposite sides of a single carrier. The grooves extend at a predetermined cant angle relative to radii of a sealing surface about which the brush seal extends. The grooves are formed between ribs which terminate in tips deformed to overlie the bristles in the groove and thereby retain the bristles on the carrier. An epoxy overlies the carrier surfaces and grooves to facilitate their retention. The brush seal may be fabricated by rolling knurled rollers with oblique cutting ribs along opposite surfaces of the carrier to form the grooves. The bristles are then wrapped about the carrier and in the grooves. Subsequently, the tips of the ribs defining the grooves are deformed to overlie and retain the bristles in the grooves.
