ABSTRACT:
A method and apparatus for sealing between relatively articulable surfaces is provided by folding a thin flexible sheet material to form a multilayer flattened elongated member. A large gap can be sealed, and seal installation and service life is improved by clamping a stiffened thickened portion of the seal member to each surface. Resulting avoidance of stress concentrations, combined with increased flexibility attributable to its multilayer construction, contributes significantly to improved installation and service performance of the seal.
