ABSTRACT:
A segmented brush seal (10) having coaxial annular backing (20) and side (25) plates sandwiching a plurality of tightly packed, circumferentially arrayed bristles (30) which extend radially inwardly at a constant circumferential skew angle, and its method of manufacture, is disclosed. The side plate (25) has a plurality of radially inwardly extending tabs (32) each having a tab end (34) which extends proximate to an inner diameter (22) of the backing plate. The sandwiched plates (20, 25) and bristles (30) are welded together at each tab (32), wherein the resulting weld zone (50) lengthwisely extends from the radially innermost tab end (34) to an outer circumferentially weld (40) at the local bristle skew angle. The seal is then lengthwisely bifurcated through each weld zone (50) at the local bristle skew angle to produce the segmented seal (10).
