Abstract
A finger seal assembly for use between a stationary member and a movable member is formed of two overlapping metallic members having a solid portion at one end and having fingers at the other end, a layer of high temperature resistant cloth being positioned between said overlapping metallic members; said fingers of one metallic member being bent over the fingers of the other metallic member to hold said fingers together, and said solid portions of said metallic members being welded together, trapping said high temperature resistant cloth between said metallic members. High pressure acts on the inner metallic member to compress the high temperature resistant cloth.
