Spiral wound gasket is manufactured by spirally winding a preformed metal strip and a filler on the outer periphery of metal winding andrels. The winding mandrel outside diameter forms the inner diameter of the gasket and the superposed metal and non-metallic windings are continually wound until the required outer diameter is attained.
