A brush seal, comprising: a bristle arrangement with a plurality of bristles; and a joint securing the bristles together; plates flanking the bristle arrangement; and a feature on the plates to receive the joint. A brush seal, comprising: a plurality of bristles, each having a first end and an opposed second end; and plates receiving the bristles therebetween, each having a first end and a second end. The first ends of the bristles extend past the first end of the plates and the second ends of the bristles reside between the first and second ends of the plates. A method of repairing a brush seal, comprising the steps of: providing a brush seal having a bristle arrangement secured between plates; removing the bristle arrangement from the plates; providing a replacement bristle arrangement; and placing said replacement bristle arrangement between the plates.

Brush seal

A method of making a bristle arrangement for a brush seal, which includes providing a bristle arrangement; severing the bristle arrangement, the bristle arrangement now having free ends; and joining the free ends. A method of reworking a bristle arrangement for a brush seal, which includes the steps of: providing a bristle arrangement; removing a section from the bristle arrangement; and adding a replacement section to the bristle arrangement.

Method of making bristle arrangement for brush seal

A bristle arrangement for use in a brush seal, comprising: a plurality of bristles arranged in a length; and a joint along the length securing the bristles together. The fixture for making the bristle arrangement, comprises: a base having a surface with an arrangement of guides thereon, the guides adapted to orient the tufts on the surface; and a cover having a surface for receiving the tufts. The cover removably mounts to the base to sandwich the tufts between the cover and the base. Making a brush seal with multiple stages comprises the steps of: providing plates and bristle arrangements; creating a stack of plates and bristle arrangements; and joining the stack.
