Abstract
A method for making a brush-tooth seal, such as a brush-tooth seal which is attachable to a turbine stator, includes obtaining a seal carrier having a groove and having seal teeth and obtaining a brush seal having bristles with tips. The brush seal is engaged in the groove and then attached to the seal carrier. Then, the tips of the bristles of the attached and engaged brush seal are cut, such as with an electric discharge machining (EDM) wire, at a predetermined distance from the longitudinal axis of the seal carrier.
