Abstract

A brush seal segment includes a plurality of bristles disposed between a pair of backing plates. The bristles are welded to one another adjacent their proximal ends and to the edges of the backing plates remote from the bristle tips. An end plate is welded to the end faces of the backing plates at each of the opposite ends of the segment. Each end plate terminates at approximately one-half the length of the bristles along the end face to prevent the bristles from bending circumferentially and axially during handling while maintaining substantially uniform flexibility of the bristles throughout the entire length of the segment.
