Abstract
The embodiments described herein provide a cloth seal for use with turbine components. The cloth seal includes first and second cloth layers. One or more central shims are positioned between the first and second cloth layers so as to block a leakage flow path. Another shim is positioned on and seals the opposite side of the first cloth layer from the one or more central shims positioned between the first and second cloth layers so as to block another leakage flow path. Yet another sealing shim may be positioned on the opposite side of the second cloth layer from the one or more central shims positioned between the first and second cloth layers to as to seal the opposite side of the second cloth layer and block another leakage flow path.
