ABSTRACT:
A method of manufacturing a brush seal for effecting a seal between relatively moving parts. Brush elements are first made by assembling bundles of bristle elements in holding tubes therefor, the brush elements then being mounted for instance by an adhesive on a carrier, so as to lie at the required disposition. The free end portions of the bristle elements are affixed to a brush seal root member, and the bristle elements are cut off at the required position between the root member and the carrier; the carrier and holding tubes--which may be re-used--are removed to leave the brush seal. A final machining of the brush seal, such as of the bristles, may be performed.
