Abstract
In order to provide simpler manufacture and lift up and blow down control, leaf elements are provided which have profile edges arranged to associate with each other in order to create a ring carousel, either about the front or rear edge of a leaf seal arrangement. In such circumstances gas flow through the leaf seal arrangement encounters the profile edge in order to adjust leaf section position for appropriate sealing efficiency.
