Abstract
The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will reamin. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.
