A turbine comprising:

• a turbine nozzle support ring having a generally axially facing first surface;
• a plurality of turbine nozzle segments each having at least one stator vane and including an inner band having a second surface in axial opposition to said first surface;
• a seal comprised of a plurality of seal segments depending from and extending radially inwardly of said inner bands for sealing engagement against said first surface to seal between high and low pressure regions on opposite sides of said seal;
• each said seal segment including a seal body having at least a first plate, an overlay of a woven metallic cloth and a distal margin covered by said cloth and engaging said first surface;
• and
• a plurality of support brackets secured to said inner bands and extending along one side of said seal segments to support said seal bodies on a low pressure side thereof, said margins of said seal bodies being flexible and preloaded to seal against said first surface.
