Japanese "fake. Using the circle [prior art] M like micro" In addition to the white and the stems, the disk is known to the outside world. There is also a kind of polyhedron (polyacetal) and the like. It is placed in a mold with a shape of urethane, and 2 urethane is injected into the mold and hardened. Moss :: A liquid disc body is fixed with polyamine, although it is made of Capricorn II. : The disc body is installed in a mold of a predetermined shape, and the: s machine forms a friction ring on the outer periphery of the disc body. Forming. However, as described above, if the false twist twist circle & is fixed to the disc body-body, as the friction ring-friction ring is separated from the disk body, it must be ... It is impossible to make a new one. The old false twisting disc is not used. ^ Another twisting disc is used for the whole replacement. The cost of the false twisting disc required for the false twist processing of silk is 6. 1 mention =, it is difficult to dispose the disc with the original used disc, s 楗 π, and it is not what Wang Li thought. ~ The effective use of Wei Gongyuan. Therefore, in order to solve this problem, the outer product of the disc body. This kind of friction soil wants to be outside Γ. As shown in FIG. 11, it is known that the inner diameter of the disc body 71 is mounted on the outer periphery of the disc body, and the outer diameter of the disc body is smaller than the outer diameter of the disc body. It must be enlarged to 314770 200403365. A false-twisting disc 73 (refer to Japanese Patent Application Laid-Open No. 51-53148) and a friction ring 72 made of polyurethane rubber are mounted on the outer periphery of the disc main body 81 with a width from the bottom as shown in FIG. 12. A groove widening toward the opening ", and a false twist disc 84 (see Japanese Publication No. Sho Sho 59-1 0 1 36) in which a rubber ring 83 fits in the groove 82. These false thumbs are round The disks 73 and 84 are basically constructed with rubber-like elastic friction rings & 83 embedded on the outer periphery of the disk bodies 71 and Μ. Therefore, when the friction rings 72 and 83 are worn, only the friction ring can be replaced. The ring does not return false twists and turns. The beauty is a structure in which the friction ring is crimped to the flat outer periphery of the disc body 71 early, and the width of the opening portion side of the outer periphery of the 04 body 81 becomes larger. The structure of the second outer capricorn 83 is not placed on the disc bodies 71 and 81. The friction ring is fixedly installed. The structure of 72'83, so when the false twisted skirts are rubbed: ^ false twisted off discs 73, 84 rotate at high speed, due to the upper 71 81, stress relaxation, the friction ring 72, 83 relative to the disc body / 1, S 1 grip Li He team you, q ... 'Ya and because of the above-mentioned high-speed rotation; the force' causes the outer circumference of Mopin 81 ..., 83 is likely to be offset or detached from the disc body 71, the purpose of the present invention is to replace the Friction ring, in order to provide a friction ring when the friction ring wears, can not only from the circle Γ and high-speed rotation during false twist processing, [invention: ^ body offset or detached false twist disk The fake disc for item M in the scope of Zhongli's patent is a disc with a shaft hole 314770 6 200403365 in the center. The disc is mounted on the outer periphery of the disc body and is embedded in the protrusion of the aforementioned tail groove. It is provided with rubber. Those with elastic elastic friction rings have dovetail grooves on the inner periphery of the friction ring.… The width of the grooves of the ribs of the hand's nucleus is the same or slightly larger than the width of the opening. :::: Bu Zhouzhi's Dovetail = Degree is set higher in the range described later. The width of the opening of the groove is approximately the same. If the range of the circle is lower, the width of the opening of the groove of the convex strip is made, and then pushed into the tail groove when the dovetail is square. , So that the disc =; the deformation of the mouth is also stable. Mouth | The fit of the limb and the friction ring is more: And the height of the convex strip on the inner circumference of the friction ring is preferably the same as the depth of the continuous tail groove, Or slightly higher. With the hardness: If the hardness is set higher in the range described below, the depth of the tail groove is approximately the same. 'The hardness of the friction ring :: = is to make the height of the ring higher than the depth, ㈣ When the convex strip pushes into the tail groove, the front end of the convex strip will be at the tail end: part of it will slightly bulge the M disc's body and frictional vibration toward the width direction. The false twisting disk of the second patent application is a disk having a shaft hole in the center of which a rubber-like elastic friction ring is mounted on the outer periphery of the disk. A groove is provided on the outer periphery of the disk body. One or a plurality of friction ring pull-out preventing protrusions are provided on the openings ^ of the two side walls of the groove, and a convex strip can be provided on the inner periphery of the friction ring to fit into the groove. 314770 7 200403365 2 items, please.. The section has a large circular shape or the "protrusion for reading prevention is horizontal and horizontal. The surface is generally triangular. Xi Yuyue, the friction ring pull-out prevention protrusion in the patent application for the second application. 7_; and in addition to claim 3 of the scope of patent application, it can also be maintained in the circumferential direction, and can be set on the entire circumference of the disc body. 、, the interval is preliminarily set and only set in the number 4 of the scope of patent application The round disc for false twisting has an outer circumference. It is equipped with a shaft hole W in the center and a humor-like friction. A recess is provided on the outer circumference of the disc body. There are opposite engagements; convex portion :: this # ::: wall: a friction ring is formed on the bottom side of the opening portion to pull out: the groove of the convex portion is provided with a convex ring corresponding to the two engagement rings described above. The inner perimeter and the engaging head formed at the front end of the ridge, the ridge of the degree is formed in a cross-section into a substantially mountain shape that can enter the groove, and the width of the transverse part of the :::: is greater than the width of the ⑽, and The two mountain feet at the foot of the mountain are used to pull out the friction ring in the aforementioned groove, > Chengyou . The invention of item 5 of the patent application scope of the engagement of the slave part is stopped in the false twist recorded in any one of the foregoing application 1 to the scope of patent application ^ Scope…… The hardness of the friction ring is in the range of A80 to AQ ^. The friction ring is better from the abrasion resistance and durability, but it is given in the false processing; to 'high hardness, elasticity and friction The original 4 has good crimpability, and requires 3M770 200403365 for a long period of time !; When the hardness is lower than Αδ0, the wear resistance is insufficient, and the size is not sufficient, and it is prone to swell deformation or corrugated secondary hardness during use. Defective conditions such as deterioration of elastic resilience may occur, which are higher than A 9 5 and the required friction characteristics cannot be obtained after a month / month. Therefore, it is best to set it within the range of A80 to A95. Also A & The hardness of the friction ring is set to the dry circumference, and the wear resistance, durability, shape%, elastic recovery, and friction characteristics of the clothing can be obtained. In addition, the surface roughness of the friction ring is rough. (Rz) is below the shirt, preferably in the range of 1 to 3. As described later. In the case of using Nishi ', P thick chain degree A) more than 4 pottery, the twisting characteristics of ^ 4㈣ at the beginning are not easy to produce uneven phenomenon, and proceed; IS quality. However, it is necessary to perform advanced test operation before the actual false twisting process, so that the friction ring is abraded & the α J clothes are worn again. In addition, the friction ring will be formed in order to improve the IX. If the hardness of the polyurethane rubber is set to be more than 1¾, then the test run time will be longer at 1 °. The aspect 'if the surface roughness (Rz) of the friction ring is less than 1 μΐΏ' makes the surface of the friction ring non-standard In the case of Dianping / Month, although the aforementioned trial operation can be omitted, but because of the contact with the blood film & one, and the other, the stripe-like unevenness is easily generated on the surface of the friction ring. ; Β Therefore, the problem of shortening the life of the friction ring is also caused. 0 In addition, the surface rough seam degree (Rz) here is Yuan Da's height as defined by Jis-B〇60〇i (2000). Degree. It is claimed that the invention in the sixth scope of the patent is a friction ring system 314770 9 200403365 made of polyurethane rubber in the disc for false cymbals described in any one of the first to the fifth scope of the aforementioned patent application.
