ABSTRACT:
A seal is provided between relatively moving parts 12, 14 and includes plural layers 24 of woven material such as metal, polymer or ceramic materials. The layers are secured to one another and to a first part 22 of the relatively moving first and second parts and extend freely from that first part into engagement with the second part. The woven material layers accommodate shape variations between the parts. In a further form, bristles 38 are disposed between layers of woven material and secured at one end to one part. The free ends of the bristles and the free marginal portion of the woven material project toward the second part in sealing engagement therewith.
