Claim:
A leaf seal assembly for providing a seal between a first member and a second member, the leaf seal assembly comprising: a plurality of leaf elements, the leaf elements being arranged in a pack, the pack arranged in a circumferential direction about the first member, each leaf element extending in a generally radial direction and having a width in an axial direction perpendicular to the radial direction and to the circumferential direction, a first cover plate, the first cover plate having a substantially total length that is substantially planar in the radial and circumferential directions, a first generally radially-extending edge of each leaf element being adjacent to the first cover plate, wherein each leaf element comprises a root portion, a sealing portion and a first shoulder formed at a boundary between the root portion and the sealing portion, the first shoulder being in the first edge, the first shoulder extending in the axial direction so as to define a first shoulder edge parallel to the first edge, the first shoulder edge abutting and directly contacting the first cover plate such that a width of the first shoulder defines a first gap between the first edge of each leaf element and the first cover plate over a portion of the first edge, wherein the root portion and the sealing portion are integrally formed as a unitary structure.
