ABSTRACT:
A method and seal assembly for sealing a rotary machine including a rotary component and a stationary component is provided. The method includes providing a plurality of flexible leaf plates in an opening defined between a pair of spaced walls that include an adjustable front wall and an adjustable back wall that is opposed to the front wall. The method also includes adjusting a width of the opening by axially adjusting at least one of the front and back walls with respect to a central rotational axis of the rotary component.
