Abstract: Seal arrangements are arranged to provide a seal edge suspended on suspension mountings to accommodate for axial movements in a component against which the edge acts. The edge is associated with a backing member so that the edge extended to a desired degree beyond the backing member to provide a good sealing function by suspending the edge it is allowed to float and so does not become excessively worn due to axial movements or excursions by the component 6, 36, 46, 56 whilst retaining the seal edge 4, 34, 44, 54 at an appropriate position for sealing efficiency. Typically, the seal edge is formed from bristles of a brush seal. A number of seal arrangements 1, 31, 41, 51 are normally arranged in a seal assembly 63.
