ABSTRACT:
This application discloses a method of producing gasketing material having an expansive solid metallic core and a densified facing covering a face of the core adhesively bonding a moderate density non-asbestos facing formed by a paper-making process to the core face and then, densifying the facing by compressing said facing in a series of at least 2 passes through compression rollers, thereby to densify said facing to a minimum of 80% of its ultimate density, while reducing the thickness of the facing to no more than 80% of its original thickness, all without significant distortion or destruction of said facing, and the gasketing material resulting from the practice of the method.
