Description of the Related Art Conventionally, as a packing using a flexible expanded graphite sheet having good bearing property and self-lubricating property, Japanese Patent Application Laid-Open No. 4-25671 discloses an expanded graphite tape in which a mountain fold and a valley are formed in the longitudinal direction. Fold it in at least one of the folds to form a cord-like body of a folding layer, and coat the outer periphery of this cord-like body with a braided body made of stainless steel wire, Inconel wire, carbon fiber, aramid fiber, or other reinforcing yarn. There is proposed a gland packing which is made into a knitting yarn and is formed by bundling or twisting a plurality of the knitting yarns.

紐状体としているので、折畳層間にすべりを生じない編
み糸が得られることから、グランドパッキンを製造する
ための編組時に膨張黒鉛テープに切断を生じないから編
組が容易になり、封止機能の高いグランドパッキンが得
られることが第１の特長点とされている。According to the structure of the gland packing described above, since the folding layer obtained by folding the expanded graphite tape is a string-like body, a knitting yarn which does not cause slippage between the folding layers can be obtained. The first feature is that the expanded graphite tape is not cut during braiding for manufacturing the gland packing, so that the braiding is easy and a gland packing having a high sealing function is obtained.

が第２の特長点とされている。Further, since the cord-like body is reinforced by the braided body of the reinforcing yarn, the integral binding force between the cord-like body and the reinforcing braided body is enhanced, and the cord-like body and the reinforcing braided body are separated from each other. The second characteristic point is that the shape retention of the knitting yarn is improved and the braiding can be facilitated to improve the sealing function of the gland packing from this point as well.

緩和性能を最大限に発揮していない。However, the gland packing having the above structure is
Since the entire folding layer obtained by folding the expanded graphite tape is covered with the reinforcing braid to form the knitting yarn, the expanded graphite and the reinforcing braid are not integrally joined together, and the cushion obtained by surely joining the both It does not maximize its properties, compression recovery rate and stress relaxation resistance.

を要旨としている。In a packing according to the first invention of the present application, a flexible expanded graphite tape having a rectangular cross section is covered with a reinforcing knitted bag body made of a fiber material, and the knitted bag body containing the graphite tape is Stretching or drawing in the longitudinal direction to make a cross section of a substantially round shape or a square shape as a knitting thread, and a plurality of these knitting threads are braided or twisted into a string without a core or with a core. That is the summary. A method for manufacturing a packing according to the second invention of the present application comprises a step of knitting a flexible expansive graphite tape having a rectangular cross-section with a fiber material in a bag shape to form a knitted bag body, and a knitted bag body containing the graphite tape. Stretching or drawing in the longitudinal direction to form a knitting yarn having a substantially round or square cross section, and braiding or twisting a plurality of the knitting yarns without a core or with a core in a string shape. The gist is that it consists of a processing step.
