Description

この発明は、たとえばスクリーン印刷やふるい分けなどに使用されるような金属製のメッシュ織物に関する。   The present invention relates to a metal mesh fabric used for, for example, screen printing and sieving.

金属製のメッシュ織物は、様々な分野で使用されている。なかでもスクリーン印刷やふるい分けなどでは、メッシュ織物の構造が作用効果に大きな影響を及ぼすので、その目的に応じて工夫がなされている。   Metal mesh fabrics are used in various fields. In particular, in screen printing and sieving, the structure of the mesh fabric has a great influence on the function and effect.

たとえばスクリーン印刷版に用いられるメッシュ織物としては、下記特許文献1に開示されたようなものがある。   For example, mesh fabrics used in screen printing plates include those disclosed in Patent Document 1 below.

これは、高膜厚の印刷を行うためのもので、経線と緯線に引っ張り強度の異なる金属線を用い、引っ張り強度の高い緯線がすべて同一平面上に並ぶようにしたものであり、線径の約3倍の厚さを有するメッシュ織物が得られる。この結果、厚い印刷膜が得られるという顕著な効果を有する。これは、紗厚が厚いほど厚い印刷膜が得られるからである。   This is for printing with a high film thickness. Metal lines with different tensile strengths are used for meridians and parallels, and all parallels with high tensile strength are arranged on the same plane. A mesh fabric having a thickness of about 3 times is obtained. As a result, there is a remarkable effect that a thick printed film can be obtained. This is because the thicker the thickness, the thicker the printed film is obtained.

特許第3710428号公報Japanese Patent No. 3710428

しかし、これまで上記の3倍厚よりも厚い金属製のメッシュ織物はなかった。また、ふるい分けに用いられる金属製のメッシュ織物においては、角目や長目などの種別があるが、基本的に平面的な開口を有したものであり、また厚さが厚いものはなかった。   However, there has been no metal mesh fabric thicker than the above three times. In addition, metal mesh fabrics used for sieving have types such as squares and longs, but basically have flat openings and no thick ones.

そこで、この発明は、厚みの厚い金属製のメッシュ織物を得て、スクリーン印刷やふるい分けに資するようにすることを主たる目的とする。   Accordingly, the main object of the present invention is to obtain a thick metal mesh fabric and contribute to screen printing and sieving.

そのための手段は、平行に配設された多数本の金属製の経線からなる経線群と、平行に配設された多数本の金属製の緯線からなる緯線群とからなるメッシュ織物であって、当該メッシュ織物が、引っ張り強度の高い高強度金属線と、該高強度金属線よりも引っ張り強度が低い低強度金属線で構成され上記経線群および緯線群が少なくとも上記高強度金属線を有するとともに、経線群と緯線群の一方または双方に、上記低強度金属線を有し、上記高強度金属線には、引っ張り強度が1900N/mm以上で伸びが5%未満の金属線が使用され、低強度金属線には、引っ張り強度が650〜1500N/mm で伸びが9%以上の金属線が使用されて、高強度金属線を略直線状に保つ一方で、低強度金属線を波打ち形状に折り曲げたメッシュ織物である Means therefor is a mesh fabric composed of a meridian group consisting of a plurality of metal meridians arranged in parallel and a latitude line group consisting of a plurality of metal latitude lines arranged in parallel, The mesh fabric is composed of a high-strength metal wire having a high tensile strength and a low-strength metal wire having a tensile strength lower than that of the high-strength metal wire, and the meridian group and the latitude line group have at least the high-strength metal wire. In one or both of the meridian group and the latitude line group, the low-strength metal wire is used, and for the high-strength metal wire, a metal wire having a tensile strength of 1900 N / mm 2 or more and an elongation of less than 5% is used. For low-strength metal wires, metal wires with a tensile strength of 650-1500 N / mm 2 and elongation of 9% or more are used to keep the high-strength metal wires in a substantially straight shape, while the low-strength metal wires are corrugated. Messi bent to A textile.

織成にあたっては、高強度金属線を略直線状に維持し、低強度金属線を波打たせるようにする。   In weaving, the high-strength metal wire is maintained in a substantially straight shape, and the low-strength metal wire is waved.

経線群と緯線群高強度金属線存在するので、メッシュ織物は厚さ方向に少なくとも2段の階層を有する構造となりその他の経線及び緯線によって、少なくとも線径の4倍程度以上5倍程度の厚さを有するメッシュ織物が得られる。 Since the high strength metallic wire are present in meridian group and parallels group, mesh fabric becomes a structure having at least two stages of hierarchy in the thickness direction, the other meridians and parallels, 5 times than about four times the least diameter A mesh fabric having a thickness of

具体的にはたとえば、上記経線群と緯線群が、それぞれ高強度金属線と低強度金属線を有するとともに、低強度金属線からなる経線と低強度金属線からなる緯線のうちの一方の波打ち形状の振幅が他方のそれよりも小さく設定されて、当該メッシュ織物の一方側の面に、経線と緯線の交点が面一状に並ぶ平滑面が形成され、他方側の面に、低強度金属線からなる経線と低強度金属線からなる緯線の交差部分が現れない粗面が形成されるとよい。ここで、「面一」とは、完全なる面一のみを意味するのではなく、略面一であれば足りるという意味である。線径の4倍厚程度のメッシュ織物が得られるとともに、一方側の面が比較的平滑な面となり、他方側の面が粗い粗面となる。 Specifically, for example, the meridian group and the latitude line group have a high-strength metal line and a low-strength metal line, respectively, and one corrugated shape of a meridian made of a low-strength metal line and a latitude line made of a low-strength metal line, respectively. Is set to be smaller than that of the other, a smooth surface is formed on one surface of the mesh fabric with the intersections of meridians and parallels being flush, and a low-strength metal wire is formed on the other surface. It is preferable to form a rough surface in which the intersection of the meridian made of and the latitude made of the low-strength metal wire does not appear . Here, the term “level” does not mean only the perfect level, but it is sufficient if the level is substantially level. A mesh fabric having a thickness about 4 times the wire diameter can be obtained, and the surface on one side becomes a relatively smooth surface, and the surface on the other side becomes a rough surface.

別の手段は、上記のメッシュ織物が枠体内に張設されたスクリーン印刷版である。   Another means is a screen printing plate in which the mesh fabric is stretched in a frame.

以上のように、この発明によれば、経線と緯線の線形が同一だとした場合、線径の4倍程度以上5倍程度の厚さを得られるので、スクリーン印刷に用いた場合には、印刷膜厚を高めることができる。また、篩に用いた場合には、立体的なメッシュ(目)によって良好な篩効果が得られる。 As described above, according to the present invention, when the meridian and the parallel of the parallel are the same, a thickness of about 4 to 5 times the wire diameter can be obtained, so when used for screen printing, The printed film thickness can be increased. Moreover, when it uses for a sieve, a favorable sieve effect is acquired by a three-dimensional mesh (eyes).

また、経線群と緯線群高強度金属線を用いたので強度の高いメッシュ織物となる。 Further , since high strength metal wires are used for the meridian group and the latitude line group , a mesh fabric with high strength is obtained.

この発明を実施するための一形態を、以下図面を用いて説明する。
図1は、金属製のメッシュ織物11の構造を示す説明図であり、図1(a)は平面図、図1(b)は図1(a)のA―A断面図、図1(c)はB―B断面図である。
An embodiment for carrying out the present invention will be described below with reference to the drawings.
1A and 1B are explanatory views showing the structure of a metal mesh fabric 11. FIG. 1A is a plan view, FIG. 1B is a cross-sectional view taken along line AA in FIG. ) Is a BB cross-sectional view.

この図1に示したように、メッシュ織物11は、平行に配設された多数本の金属製の経線22…,23…からなる経線群21と、平行に配設された多数本の金属製の緯線32…,33…からなる緯線群31とが平織されてなるものである。   As shown in FIG. 1, the mesh fabric 11 is composed of a plurality of metal meridians 22 ..., 23 ... arranged in parallel and a plurality of metal meridians 21 arranged in parallel. The latitude lines 32..., 33.

経線群21と緯線群33を構成する金属線には2種類の金属線を使用する。2種類の金属線は、引っ張り強度の異なる金属線のことであり、引っ張り強度の高い高強度金属線(経線22、緯線32)とこれよりも引っ張り強度の低い低強度金属線(経線23、緯線33)とを用いる。高強度金属線は曲げることができないが、低強度金属線は曲げることができる。すなわち、高強度金属線をあまり曲げずに低強度金属線を曲げて波打たせたような形状にすることによってメッシュ織物11を形成する。   Two types of metal wires are used for the metal wires constituting the meridian group 21 and the latitude group 33. The two types of metal wires are metal wires having different tensile strengths. The high-strength metal wires having high tensile strength (meridians 22 and latitude lines 32) and the low-strength metal wires having lower tensile strength (meridians 23 and latitude lines). 33). High strength metal wires cannot be bent, but low strength metal wires can be bent. That is, the mesh fabric 11 is formed by bending the low-strength metal wire into a wave shape without bending the high-strength metal wire too much.

織成にあたっては、これら高強度金属線と低強度金属線を、1本ずつ交互に織り込む。   When weaving, these high-strength metal wires and low-strength metal wires are woven one by one alternately.

高強度金属線としては、引っ張り強度が1900N/mm以上で伸びが5%未満のものを使用でき、低強度金属線としては、引っ張り強度が650N/mm〜1500N/mmで伸びが9%以上のものが使用できる。なお、各経線22,23と緯線32,33の線径d1,d2,d3,d4や、目開きOP(オープニング)、メッシュ数などの平織の条件は、所望のメッシュ織物11が得られるように適宜設定される。 A high strength metal wire having a tensile strength of 1900 N / mm 2 or more and an elongation of less than 5% can be used, and a low strength metal wire has a tensile strength of 650 N / mm 2 to 1500 N / mm 2 and an elongation of 9 % Or more can be used. It should be noted that the plain weaving conditions such as the diameters d1, d2, d3, d4 of the meridians 22, 23 and the latitudes 32, 33, the opening OP (opening), and the number of meshes are set so that a desired mesh fabric 11 is obtained. Set as appropriate.

このように交互に配設された高強度金属線と低強度金属線を経線群21と緯線群31に用いたメッシュ織物11は、経線群21と緯線群31に低強度金属線を有するので、これらの交差部分41のメッシュ織物11における厚みt方向での位置が、図1(b)、図1(c)に示したように、メッシュ織物11の厚みt方向の内側寄りに位置する。このときに、交差部分41がメッシュ織物11の一方側(図面下側)の面から突出せず、又はいり込まないように設定する。換言すれば、金属線の線径ひとつ分だけ、内側に寄せる。すなわち、上記の交差部分41を構成する経線23と緯線33の厚み方向の一方側(図面下側)の端部41aが、メッシュ織物11の一方側(図面下側)の面で面一になるように設定する。この「面一」とは、完全なる面一のみを意味するのではなく、略面一であればよいという意味である。   Since the mesh fabric 11 using the high-strength metal wires and the low-strength metal wires arranged alternately in this way for the meridian group 21 and the latitude group 31 has the low-strength metal wires in the meridian group 21 and the latitude group 31, The positions of these intersecting portions 41 in the thickness t direction in the mesh fabric 11 are located closer to the inside in the thickness t direction of the mesh fabric 11 as shown in FIGS. 1 (b) and 1 (c). At this time, it is set so that the intersecting portion 41 does not protrude from the surface of one side (the lower side in the drawing) of the mesh fabric 11 or is not inserted. In other words, the metal wire is moved inward by one wire diameter. That is, the end 41a on one side (lower side in the drawing) of the meridian line 23 and the parallel line 33 constituting the intersecting portion 41 is flush with the surface on one side (lower side in the drawing) of the mesh fabric 11. Set as follows. The term “level” does not mean that the plane is completely flush, but that it is sufficient if it is substantially flush.

これにより、波打ち形状に上下に折れ曲がる低強度金属線(経線23、緯線33)のうちの一方の低強度金属線(図示例では緯線33)の波打ちの振幅が小さくなり、メッシュ織物11の一方側の面には、比較的平滑な面(以下、「平滑面11a」という。)が得られる(図1(c)参照)。   As a result, the amplitude of the undulation of one of the low-strength metal wires (the meridian 23 and the latitude line 33) of the low-strength metal wires that are bent up and down into a wavy shape is reduced, and one side of the mesh fabric 11 is reduced. A relatively smooth surface (hereinafter referred to as “smooth surface 11a”) is obtained (see FIG. 1C).

一方、これと反対側(図面上側)の面(以下、「粗面11b」という。)は、波打ち形状に上下に折れ曲がる低強度金属線のうちの他方の低強度金属線(図示例では経線23)の湾曲部分23aが、1本おきに突出する状態となり、凸状の湾曲部分23aが粗く点在する構造となる。   On the other hand, the surface on the opposite side (upper side in the drawing) (hereinafter referred to as “rough surface 11b”) is the other low-strength metal wire (in the example shown, meridian 23) among the low-strength metal wires that bend up and down in a wavy shape. ) Curved portions 23a protrude every other line, and the convex curved portions 23a are roughly scattered.

スクリーン印刷版に用いるメッシュ織物11であって高膜厚の印刷を行おうとする場合には、高強度金属線としては、たとえば上記例のうち、2800N/mmで伸びが2〜3%ものを、また低強度金属線としては、たとえば上記例のうち、1000N/mmで伸びが25〜30%のものを使用するとよい。この場合、各金属線の線径は、50μm以下のものを使用するのがよい。 When the mesh fabric 11 used for the screen printing plate is to be printed with a high film thickness, the high-strength metal wire is, for example, 2800 N / mm 2 of the above example with an elongation of 2 to 3%. Moreover, as a low intensity | strength metal wire, it is good to use a thing with elongation of 25-30% by 1000 N / mm < 2 > among the said examples, for example. In this case, the diameter of each metal wire is preferably 50 μm or less.

一例として、線径d1,d3が28μmで引っ張り強度が2800N/mm、伸びが2〜3%の高強度金属線と、線径d2,d4が28μmで引っ張り強度が1000N/mm、伸びが25〜30%の低強度金属線とを用いて、メッシュ数325、目開き50μmのメッシュ織物を、上記の構造になるように織成して得た。すると、このメッシュ織物の厚さ(紗厚)は、111μmであった。これは線径d1,d2,d3,d4の3.96倍、およそ4倍の厚さであった。 As an example, a high-strength metal wire having a wire diameter d1, d3 of 28 μm and a tensile strength of 2800 N / mm 2 and an elongation of 2 to 3%, a wire diameter d2 and d4 of 28 μm, a tensile strength of 1000 N / mm 2 and an elongation of A mesh fabric having a mesh number of 325 and an opening of 50 μm was woven using the low-strength metal wire of 25 to 30% so as to have the above structure. The thickness of the mesh fabric (thickness) was 111 μm. This was 3.96 times the wire diameters d1, d2, d3, and d4, and about 4 times the thickness.

このメッシュ織物11を枠体(図示せず)に張設してスクリーン印刷版(周知の構造ゆえ図示省略)を製造し、下記の条件でスクリーン印刷を行い、塗布厚を調べたところ、22.3μmであった。   When this mesh fabric 11 is stretched on a frame (not shown) to produce a screen printing plate (not shown because of a well-known structure), screen printing is performed under the following conditions, and the coating thickness is examined. It was 3 μm.

印刷は、自動印刷機(マイクロテック株式会社製の高精度スクリーン印刷機MT―320TV)を使用し、2Kg/cmのスキージ圧力を加え、40mm/secの速度で行った。印刷ペーストとしては、市販の高粘度ガラスフリット(微細ガラスビーズの入ったペースト)を使用した。また印刷は、上記の平滑面をスキージ側に、粗面を被印刷物側にして行った。 Printing was performed using an automatic printer (high-precision screen printer MT-320TV manufactured by Microtech Co., Ltd.), applying a squeegee pressure of 2 Kg / cm 2 and a speed of 40 mm / sec. As the printing paste, a commercially available high-viscosity glass frit (a paste containing fine glass beads) was used. Printing was performed with the smooth surface on the squeegee side and the rough surface on the substrate side.

比較例として、線径が28μmで引っ張り強度が2500N/mmの高強度金属線を緯線、線径が28μmで引っ張り強度が1000N/mmの低強度金属線を経線として、すべての緯線が同一平面状に並ぶように織成して、線径の3倍厚のメッシュ織物を得た。メッシュ数、目開きは上記の例と同一である。このメッシュ織物の厚さ(紗厚)は、77μmで、これは線径の2.75倍の厚さであった。そして、上記と同一条件でスクリーン印刷を行い、塗布厚を調べたら、14.5μmであった。 As a comparative example, the wire diameter is tensile strength at 28 .mu.m is 2500N / mm 2 high strength metal wire parallels the meridian low strength metallic wire having a diameter that is tensile strength at 28 .mu.m 1000 N / mm 2, all parallels same A mesh fabric having a thickness three times as large as the wire diameter was obtained by weaving in a plane. The number of meshes and openings are the same as in the above example. The thickness of the mesh fabric (thickness) was 77 μm, which was 2.75 times the wire diameter. And when screen printing was performed on the same conditions as the above and the coating thickness was investigated, it was 14.5 micrometers.

上述のように、メッシュ織物は4倍ほどの厚さとなり、スクリーン印刷に用いた場合には、上記のごとく印刷膜厚を高めることができた。   As described above, the mesh fabric was about four times thicker, and when used for screen printing, the printed film thickness could be increased as described above.

また、経線群21と緯線群31の双方に高強度金属線を用いたので、強度が高く、耐摩耗性の良好なメッシュ織物11となる。   In addition, since high strength metal wires are used for both the meridian group 21 and the latitude line group 31, the mesh fabric 11 has high strength and good wear resistance.

さらに、メッシュ織物には平滑面11aと粗面11bが存在するので、平滑面11aをスキージ側に、粗面11bを被印刷物側にして印刷を行うと、平滑面11aは全体的に滑らかであって、スキージの磨耗を低減できる。一方、粗面11bは凸部が点在することになるが、面積の割に接触する部分の数が少なく粗い。このため、印刷時に被印刷物に対する接点を低減することができ、この結果、被印刷物の表面の平滑性が高くなり、干渉縞などの発生を防止して、美麗な印刷をすることができる。   Further, since the mesh fabric has a smooth surface 11a and a rough surface 11b, when printing is performed with the smooth surface 11a on the squeegee side and the rough surface 11b on the substrate side, the smooth surface 11a is generally smooth. Thus, squeegee wear can be reduced. On the other hand, the rough surface 11b is interspersed with convex portions, but the number of portions in contact with the area is small and rough. For this reason, the contact point with respect to a to-be-printed object at the time of printing can be reduced, As a result, the smoothness of the surface of a to-be-printed object becomes high, generation | occurrence | production of an interference fringe etc. can be prevented and beautiful printing can be performed.

さらにまた、メッシュ織物11の厚さが厚い分、上下に波打つ低強度金属線(図示例では経線23)の傾斜する部分23bは比較的長い(図1(b)参照)。このため、スクリーン印刷においては、この傾斜部分では目は大きく、長いオープニングを得たのと同様にペーストが透過しやすい。   Furthermore, as the thickness of the mesh fabric 11 is thick, the inclined portion 23b of the low-strength metal wire undulating up and down (the meridian 23 in the illustrated example) is relatively long (see FIG. 1B). For this reason, in screen printing, the eyes are large at the inclined portion, and the paste is easily transmitted as in the case of obtaining a long opening.

上記のような構造のメッシュ織物11を、ふるい分けに用いる篩の枠体(図示せず)に張設し、篩(周知の構造ゆえ図示省略)を得る場合には、メッシュ織物11の粗面11bを上面側に、平滑面11aを下面側に設定する。メッシュ織物11を構成する経線22,23および緯線32,33の条件、織成条件は、篩にかける粉体の種類等に応じして適宜設定される。   When the mesh fabric 11 having the above structure is stretched on a sieve frame (not shown) used for sieving to obtain a sieve (not shown because of a well-known structure), the rough surface 11b of the mesh fabric 11 is used. Is set on the upper surface side, and the smooth surface 11a is set on the lower surface side. The conditions of the meridians 22 and 23 and the latitude lines 32 and 33 constituting the mesh fabric 11 and the weaving conditions are appropriately set according to the type of powder to be sieved.

このような篩によれば、メッシュ織物11の表面の凹凸が多くなるので、メッシュ織物11の上にのった粉体が分散しやすい。そのうえ立体的な目を有し、上述のように上下に波打つ低強度金属線(経線23)の傾斜する部分23bは長い。このため、良好な篩作用が得られる。   According to such a sieve, the unevenness of the surface of the mesh fabric 11 increases, so that the powder on the mesh fabric 11 is easily dispersed. In addition, the inclined portion 23b of the low-strength metal wire (meridian 23) that has three-dimensional eyes and undulates vertically as described above is long. For this reason, a good sieving action is obtained.

なお、上述の例では、経線群21と緯線群31の双方に、高強度金属線と低強度金属線を用いたが、経線群21または緯線群31のいずれか一方のみに高強度金属線と低強度金属線を用いることもできる。この場合、他方は、高強度金属線のみとする。 In the above example, a high-strength metal wire and a low-strength metal wire are used for both the meridian group 21 and the latitude line group 31, but a high-strength metal wire is used only for either the meridian group 21 or the latitude line group 31. A low strength metal wire can also be used. In this case, the other is Mito high strength metal wire.

その一例を、図2に示した。この説明において、上記の構成と同一または同等の部位については同一の符号を付してその詳しい説明を省略する。   An example is shown in FIG. In this description, the same or equivalent parts as those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

図2(a)はメッシュ織物11の平面図、図2(b)は図2(a)のA―A断面図、図2(c)はB―B断面図である。すなわち、図2のメッシュ織物11は、経線群21には、先の例と同様に、高強度金属線からなる緯線22と低強度金属線からなる緯線23を1本ごと交互に配設したものを用い、緯線群31を構成する緯線32…には、すべてに高強度金属線を用いた。   2A is a plan view of the mesh fabric 11, FIG. 2B is a cross-sectional view taken along the line AA in FIG. 2A, and FIG. 2C is a cross-sectional view taken along the line BB. That is, in the mesh fabric 11 of FIG. 2, in the meridian group 21, like in the previous example, latitude lines 22 made of high-strength metal lines and latitude lines 23 made of low-strength metal lines are alternately arranged one by one. , And the latitude lines 32 constituting the latitude line group 31 are all high-strength metal wires.

上記の高強度金属線としては、引っ張り強度が1900N/mm以上で伸びが5%未満のものを使用でき、低強度金属線としては、引っ張り強度が650N/mm〜1500N/mmで伸びが9パーセント以上のものが使用できる。また、各経線22,23と緯線32の線径d1,d2,d3や、目開き(オープニング)、メッシュ数などの平織の条件は、所望のメッシュ織物11が得られるように適宜設定される。図示例では、各経線22,23と緯線32の線径d1,d2,d3を同一に設定した。 As the above-mentioned high-strength metal wires, those having a tensile strength of 1900 N / mm 2 or more and an elongation of less than 5% can be used, and as low-strength metal wires, the tensile strength is 650 N / mm 2 to 1500 N / mm 2 . 9% or more can be used. The plain weaving conditions such as the wire diameters d1, d2, d3 of the meridians 22, 23 and the latitude lines 32, the opening (opening), and the number of meshes are appropriately set so that the desired mesh fabric 11 is obtained. In the illustrated example, the diameters d1, d2, and d3 of the meridians 22 and 23 and the latitude line 32 are set to be the same.

このような金属線からなるメッシュ織物11では、高強度金属線(経線22、緯線32)をあまり曲げずに低強度金属線(経線23)のみを曲げて波打たせたようにして織成がなされる。この結果、図2に示したように、メッシュ織物11の厚さtは、各経線22,23や緯線32の線径d1,d2,d3のおよそ5倍の厚さとなる。   In the mesh fabric 11 made of such metal wires, weaving can be performed by bending only the low-strength metal wires (meridians 23) without undulating the high-strength metal wires (meridians 22, latitude lines 32). Made. As a result, as shown in FIG. 2, the thickness t of the mesh fabric 11 is approximately five times as large as the diameters d1, d2, and d3 of the meridians 22 and 23 and the latitude lines 32.

このようなメッシュ織物11をスクリーン印刷版に用いれば、さらに高膜厚の印刷ができ、また、篩に用いれば、立体的な目による粉体に応じた効果的なふるい分けが可能となる。   If such a mesh fabric 11 is used for a screen printing plate, printing with a higher film thickness can be performed, and if it is used for a sieve, effective sieving according to the powder with a three-dimensional eye is possible.

上記の構成は、この発明の一実施の形態であって、この発明は上記の構成のみに限定されるものではなく、その他の形態を採用することもできる。   The above configuration is an embodiment of the present invention, and the present invention is not limited to the above configuration, and other modes can be adopted.

たとえば、高強度金属線と低強度金属線を1本ごと交互に配設するのではなく、数本おきに配設するなどするもよい。   For example, instead of alternately arranging the high-strength metal wires and the low-strength metal wires one by one, it may be arranged every few wires.
