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.
Claims14
A method of manufacturing a brush seal, which method comprises the steps of:
- (a) assembling a multiplicity of bristle elements in a holding tube with said bristle elements projecting from the holding tube by a pre-set distance thereby forming a brush element;
- (b) assembling a plurality of said brush elements on a carrier with said brush elements lying at pre-set angles relative to said carrier;
- (c) affixing to a root member the free end portions of said bristle elements projecting from their holding tubes;
- (d) severing all said bristle elements part-way between their holding tubes and said root member so that said severed bristle elements project for a predetermined distance from said root member;
- and
- (e) removing said carrier with said holding tubes, leaving a brush seal with projecting bristles.
