发明名称 MANUFACTURE AND TUBULAR PACKING
摘要 PROBLEM TO BE SOLVED: To secure tubular packing that is ease of manufacture and excellent in durability by making the best use of its features in cushionability and heat resistance is expanded graphite. SOLUTION: This packing is formed into tubular packing by preparing a sheat piece 11 of expanded graphite and two sheets of wire gauze pieces 12 and 13 of nearly the same from, regularly interposing the wire gauze piece 12 on the surface of the sheet piece 11 interposing the wire gauze piece 13 at the backside shifted by on the sheet piece 11 curving it into a cylindrical form, and compressively forming in the plate thickness direction, to form a cylindrical parking. In this constitution, the wire gauze pieces 12 and 13 are embedded in the sheet piece 11, thereby formed into the cylindrical packing. The wire gauze piece 13 is bridged and connected in an interval between both end edges 11a and 11b of the sheet piece 11, and thereby a circumferential surface is continued around. The embedded wire gauze pieces 12 and 13 are exposed on both sides of the sheet piece 11, making them turn to a commingled surface mixed with the wire gauze and the expanded graphite, so that it is excellent is wear resistance and sliding characteristics in particular.
