ABSTRACT:
A spiral wound gasket made of an elongate band with a portion of the elongate band jacketed by a resilient filler material, the jacketed elongate band wrapped in a plurality of overlapping turns to define a radially thick reinforcing member with the band in each turn enclosed by resilient filler material that abuts contactingly to the resilient filler material in an adjacent turn, the overwrapped portions of the elongate band defining opposing sealingly resilient lateral surfaces, with a leading portion and a trailing portion of the elongate band lacking the jacketing resilient filler material and adjacent turns of the leading portion secured together to fix an inner diameter and adjacent turns of the trailing portion secured together to fix an outer diameter. A method and apparatus is disclosed to wind an elongate band jacketed by a filler material around the perimeter of a die until a desired radially thick spiral wound gasket is formed.
