ABSTRACT:
A gasket assembly is made by securing together in a flexible, elongated gasket subassembly, a first, elongated, flexible tube of braided glass fiber and an adjoining, flexible, second, elongated knit wire mesh tube member by sewing together the first tube and the second tube member. Braid of the first tube permits elongation of that tube under tension. The adjoining tubes are secured together along their lengths in states of elongation such that the second tube member is fully elongated under tension, to the extent permitted by its metal wire fabric, before the first tube is stretched to a maximum elongation permitted by the braid. The resulting elongated flexible assembly is threaded onto an elongated, substantially rigid frame member, preferably by threading the frame member through a sleeve formed in the knit wire mesh tube member by the stitching. The flexible subassembly is stretched under tension on the frame and portions of the second, knit wire mesh member are secured to the frame member under tension, preferably by spot welds, to hold the flexible subassembly under tension fixed to the frame.
