Abstract
A method of manufacturing a brush seal includes wrapping wire about spaced frames to form a pair of wire runs of multiple wire thicknesses. Two pairs of interior plates are inserted between the wire runs at an angle and in spaced relation to one another. Two pairs of plates are applied along the outside of the wire runs parallel to the pairs of interior plates, respectively. By removing the wire run outside the plates and welding along each of the opposite edges of the wire run securing an interior plate, a cut end of a wire run and an exterior plate to one another, and by cutting each wire run preferably in half, four tee shaped bristle packs are formed with the bristles extending at the appropriate angle. By cutting the tee shaped packs to length and rolling the cut pack, a brush seal is formed to the appropriate diameter.
