実施例の工業用織物、すなわちドライヤーカンバスの継手を、表１に示す仕様に基づいて製作した。
【０１１２】
すなわち、経糸２６に、材質が抄紙用ドライヤーカンバス用の原糸として一般に入手可能な耐加水分解性能の良好なＰＥＴで、直径寸法０．８０ｍｍの断面円形モノフィラメントを用い、緯糸２７に、経糸と同じ材質で直径寸法０．９０ｍｍの断面円形モノフィラメントを用いて、平織組織により製織し、公知、常用の装置と方法を用いて、ヒートセット加工を施し、経糸密度が１２．０本／２．５４ｃｍ、緯糸密度が１２．０本／２．５４ｃｍの織物本体を作成した。
【０１１３】
作成した織物本体を、図３（Ａ）に示すように、所定長さ、幅寸法に切断し、長さ方向の両端部において、図３（Ｂ）に示すように、織物２０の端部から内側の所定長にわたって緯糸２７を除去することにより、経糸２６をすだれ状に延出した。
【０１１４】
この織物本体を、ヘルドのメールに挿通した糸条を紋栓カードに設定してある規定の織組織パターンに従って上下に開口することのできる図４に示すジャガード装置２１を備えた継手部織機２２に仕掛けた。仕掛ける要領は、図４に示すように、先ず、織物端部より除去した緯糸２７のうち継手部の製織に必要な所定本数を、継手部織機２２で製織する際の経糸２３として、継手部織機２２の開口装置、すなわちジャガード装置２１に備わるヘルドのメール（図示省略）に挿通して仕掛け、さらに、接合用ループ形成芯線４１（図８を参照）を、継手部の先端側に、先に仕掛けた前記継手部織機２２で製織する際の経糸２３に隣接させて、ヘルドのメールに通した状態で仕掛けた後に、経糸２６をすだれ状に延出した前記織物本体２０を、先に仕掛けた前記継手部織機２２で製織する際の経糸２３に隣接させて、前記接合用ループ形成芯線４１と反対側に仕掛けた。
【０１１５】
形成後の継手部で最先端になる緯糸２８、すなわち継手部織機２２における端部から２番目の経糸４５ｂには、前記織物本体の経糸２６と同じ材質で直径寸法０．７０ｍｍの断面円形モノフィラメントを用いた。また、接合用ループ形成芯線４１、すなわち継手部織機２２における最端部の経糸４５ａには、直径寸法０．６０ｍｍの断面円形ステンレス線を用いた。さらに、接合用ループ糸条３５としては、織物本体を構成する経糸２６とは別の、材質が抄紙用ドライヤーカンバス用の原糸として一般に入手可能な耐加水分解性能の良好なＰＥＴで、乾熱収縮率が１６０℃で１２．３％の高収縮性の、直径寸法０．５０ｍｍの断面円形モノフィラメントを用いた。
【０１１６】
継手部織機２２における緯糸として、織物本体を構成する前記すだれ状に延出した経糸２６を用いて、前記すだれ状に延出した経糸２６の１本ずつを、継手部織機２２における端部から２番目の経糸４５ｂを捲回させて折り返した後、織物本体の平織組織に従って織り込んだ。
【０１１７】
前記すだれ状に延出した経糸２６の１本ずつを継手部織機２２における緯糸２５として、継手部織機２２における端部から２番目の経糸４５ｂに捲回させて折り返す毎に、接合用ループ糸条３５を、接合用ループ形成芯線４１の周りに捲回させて接合用ループを形成して後に折り返し、継手部織機２２における端部から２番目の経糸４５ｂの位置まで延ばし、次に継手部織機２２における端部から２番目の経糸４５ｂの周りに接合用ループ形成芯線４１への捲回方向と反対方向に捲回させると共に、前記すだれ状に延出した経糸２６の折り返した部分にも絡ませて折り返した後、接合用ループ形成芯線４１の位置まで延ばし、さらに接合用ループ形成芯線４１の周りに先と同じ捲回方向に捲回させて接合用ループを形成して後に折り返し、続いて、継手部織機２２における端部から２番目の経糸４５ｂの上側（図１では紙面手前側）で前記接合用ループ形成芯線４１への捲回方向と反対方向に捲回させ、さらに継手部織機２２における端部から３番目の経糸４５ｃの位置まで延ばし、さらに継手部織機２２における端部から３番目の経糸４５ｃの周りを接合用ループ形成芯線４１への捲回方向と同じ方向に捲回させて折り返し、続いて、継手部織機２２における端部から２番目の経糸４５ｂの下側（図１では紙面奥側）で前記継手部織機２２における端部から３番目の経糸４５ｃへの捲回方向と反対方向に捲回させ、さらに接合用ループ形成芯線４１の位置まで延ばし、さらに接合用ループ形成芯線４１の周りを先と同じ捲回方向に捲回させて接合用ループを形成して後に折り返した。以上の操作を織物の幅方向にわたって繰り返して、織物の両端部のそれぞれに、接合用ループ糸条３５を、接合用ループ形成芯線４１、継手部織機２２における端部から２番目の経糸４５ｂおよび継手部織機２２における端部から３番目の経糸４５ｃに対して綴り込むことによる多数の接合用ループから成る接合用ループ列４０を形成した。
【０１１８】
さらに、接合用ループ糸条３５が綴り込まれている部分および接合用ループ列４０にヒートセット加工を施して寸法と形状を安定化させた後、接合用ループ形成芯線４１を接合用ループ列４０から取り外して、工業用織物、すなわちドライヤーカンバスの継手を有する織物を作成した。
【０１１９】
上記による継手の形成に要した時間は、図２４に示した従来の継手、すなわち、織物端部から、経糸１１，１１間に高強力な細い別糸よりなるループ形成糸１３が折り返されながら連続的に綴り込まれ、端部の折り返し部分において該ループ形成糸１３による接合用ループ１４が形成される継手の形成に要した時間の略１／５の時間であり、継手形成に要する作業時間が大幅に短縮した。
【０１２０】
この織物を製紙機械のカッターマシンに掛け入れて、織物両端部の接合用ループ列同士を交互に噛み合わせ、噛み合わせて形成した共通孔に接合芯線を挿入し、無端状織物として使用した。接合用ループ列同士の噛み合わせの作業性、ならびに、接合芯線の挿入の作業性は、極めて良好であった。
【０１２１】
また織物の使用に際して、接合用ループ糸条３５を綴り込んだ部分や、織物本体を構成する経糸２６を折り返して織物本体の平織組織に従って織り込んだ部分への、紙粉その他の汚れ物質の顕著な付着、堆積は見られず、それに起因した紙シートの吸引性能の低下による操業トラブルは発生しなかった。
【０１２２】

[Industrial application fields]
The present invention relates to a papermaking machine fabric such as a paper making dryer canvas, a conveyor belt for a cutter machine, a filter belt used in various sludge and slurry dehydrating machines including a belt press dehydrator, or a general conveying belt, The present invention relates to a joint for various industrial fabrics such as a dryer belt and a method for producing the joint.
[0002]
More specifically, a loop made of bonding is formed at both ends of the fabric using a yarn made of a synthetic resin monofilament or synthetic fiber yarn different from the warp constituting the fabric, or a joint formed by these yarns. A joining loop row is formed by attaching the members to both ends of the fabric, and the fabric is joined endlessly by inserting the joining core wire into the common hole formed by meshing the joining loop rows. The present invention relates to an industrial fabric joint and a method for manufacturing the joint.
[0003]
[Prior art]
Conventionally, there are various kinds of joints for joining industrial fabrics in an endless manner. For example, as shown in FIGS. 21 to 23, warp 1 and weft 2 (in the length direction of industrial fabrics, that is, in the machine direction). In a dryer canvas for paper making, which is woven in an open mesh of a single layer fabric, particularly a plain weave fabric, weft yarns 2 at the ends at the ends of the base fabric. The two warp yarns 1 adjacent to each other of the extended warp yarn 1 extended by removing the yarn are folded to form a joining loop 3, and the other is cut and removed according to the folded length of the one warp yarn 1. Then, the folded warp 1 is bound into the lacking portion of the warp 1 generated by this removal, and the spiral wire 4 is engaged with the joining loop 3 (FIG. 23), or the spiral wire 4 is joined to the joining loop 3. And inserted into the joining loop 3 The in engaged with the auxiliary core 5 (Fig. 21, Fig. 22) there is to be joint (e.g., see Patent Document 1.).
[0004]
As another joint, for example, as shown in FIG. 24, in an open mesh type papermaking dryer canvas in which the warp yarn 11 and the weft yarn 12 are plain woven fabrics, a high-strength thin wire between the warp yarns 11 and 11 from the fabric end. A loop forming yarn 13 made of another yarn is continuously bound while being folded, and a joint portion 14 is formed with a loop 14 for joining by the loop forming yarn 13 at the folded portion of the end. By using a yarn having a diameter smaller than that of the warp 11, the loop forming yarn 13 is located at a position lower than the front and back surfaces of the canvas body, and there is a yarn that is hardly subjected to wear during canvas travel ( For example, see Patent Document 2.)
[0005]
[Patent Document 1]
Japanese Utility Model Publication No. 7-40800 (Claim 1, FIGS. 1 to 3)
[Patent Document 2]
Japanese Utility Model Publication No. 58-128999 (P.2 to P.4, FIGS. 1 and 2)
[0006]
[Problems to be solved by the present invention]
However, in the joint disclosed in Patent Document 1, the tension applied in the warp direction of the fabric when the industrial fabric is used acts so as to pull the spiral wire 4 in the warp direction. Even if the thickness of the cross-sectional shape of the spiral defined by the thickness (thickness b in FIG. 22) decreases, the spiral wire 4 is formed at least in the thickness (c) of the joining core wire (not shown). It does not become smaller than the thickness a (= c + 2d) obtained by adding twice the thickness (d) of the wire, and the thickness b or the thickness a depends on the selection of the wire and spiral shape of the spiral wire 4 to be used. The thickness of the joint specified by the above becomes thicker than the thickness of the main body of the fabric, and there is a risk of causing defects in product quality due to marking the transported material such as wet paper (paper sheet).
[0007]
Further, the most advanced weft 2a of the wefts 2 intersects with the warp 1 according to the plain weave structure. In particular, although there is a joining loop 3 formed by folding the warp 1 on the tip side of the fabric. Compared with the other wefts 2, the restraint due to the crossing with the warp 1 is weak, and the most advanced weft 2a may move or come out in the tip direction or the width direction during use.
[0008]
In addition, in the joint disclosed in Patent Document 2, it takes a lot of time and labor to bind the loop forming yarn 13 made of another yarn and to form the joining loop 14, and in particular, use conditions of high temperature and high tension. Depending on the situation, the fabric-side folded portion 15 of the loop forming yarn 13 is pulled in the direction of the warp 11 when used for a long period of time, and in the weave 16 between the interlaced portions of the warp 11 and the weft 12, the joining loop 14 The loop forming yarn 13 may loosen. In order to prevent the loop forming yarn 13 from loosening, the loop forming yarn 13 can be turned back with an adhesive or the loop forming yarn 13 can be turned back, for example, as shown by a broken line in FIG. 24 (see a circled portion 17). The lower side is arranged on the weft 12 and the other side (the upper side in the figure) is arranged on the lower side of the weft 12 so that the warp yarn 11 and the weft yarn 12 are stitched into a tangled shape. If it does, a convex part will be produced with an adhesive agent, or the location which a loop formation thread | yarn 13 cannot be spelled along the woven structure of an edge part (tacking-like part) will arise, and it may become a convex part.
[0009]
Furthermore, in addition to the woven structure at the end of the woven fabric, the loop forming yarn 13 made of another yarn is bound, so that the gap of the weave is narrowed and the air permeability of the portion is reduced, or paper dust or other dirt substances are present in the portion. Since it easily adheres and accumulates and may cause clogging, dry spots on transported paper such as wet paper (paper sheets), especially when used as a dryer canvas in the drying process of a paper machine or in general drying processes, etc. There is a risk that the quality may deteriorate. Moreover, in the conveyance belt for an open mesh cutter machine or the like, the performance of sucking a conveyance object such as a paper sheet from the back side of the conveyance belt due to clogging generated in the portion where the loop forming yarn 13 is bound is reduced. May lead to separation of the paper sheet.
[0010]
In view of the drawbacks of the above-described conventional industrial fabric joints, the present invention forms a joining loop row by binding a yarn different from the warp constituting the fabric at each end of the fabric, or A joining member having a joining loop row formed by different yarns is attached to each end of the fabric to form a joining loop row, and joined to a common hole formed by meshing the joining loop rows. This relates to an improvement in a joint for an industrial fabric for inserting a core wire and joining the fabric endlessly, and the joint portion equivalent to the fabric body, that is, the dimensional thickness and characteristics are equivalent. It is possible to maintain the good surface quality and air permeability of the joint part, eliminate the product quality problems of the conventional joint, and reduce the time and labor when producing the joint part compared to the conventional joint. A significant reduction in manpower is possible, And to provide a joint and a method of manufacturing work for the fabric.

[0035]
FIG. 7 is a perspective view of still another joining member 34C having a shape 34c formed by mixing the two types of wound loop shapes (34a, 34b). For example, as shown in FIG. A loop for joining consisting of continuous synthetic resin monofilaments with respect to three loop-forming core wires: a forming core wire 31, a loop forming core wire 32 for engaging the main body weft, and a loop forming core wire 33 for engaging the second weft from the main body. It is obtained by winding the yarn 30 while alternately changing the winding direction, and performing heat treatment in the wound state. FIG. 7 shows an example of a joining member 34C formed by alternately mixing the two types of wound loop shapes (34a, 34b). In any of the cases shown in FIGS. 5 to 7, the joining member 34 having the joining loop row 40 composed of a number of joining loops formed around the joining loop forming core wire 31 is formed.
[0036]
Next, an example will be described below in which a joining member 34 having the joining loop row 40 separately formed is attached to both ends of the fabric to form a joining loop row.
[0037]
First, as shown in FIG. 3, in the longitudinal direction both ends 24 {state of FIG. 3 (A)} of the fabric 20 composed of warp yarns 26 and weft yarns 27, for example, woven into a plain weave structure, over a predetermined length. The weft 27 is removed, and the warp 26 is extended in a comb shape from the end of the fabric (the state shown in FIG. 3B).
[0038]
FIG. 1 shows a joint structure in which a joining member 34C having a wound loop shape 34c in which two types of wound loop shapes (34a, 34b) shown in FIG. FIG. 2 is a cross-sectional view along the warp direction after forming the joint of FIG. 1 for explaining Step 1 to Step IV in the procedure for creating the joint part of FIG.
[0039]
In order to create this type of joint, first, a predetermined number of the wefts 27 removed from the fabric end 24 is used as a warp 23 when weaving by the joint loom 22, and an opening device of the joint loom 22, for example, It is inserted into a heald mail (not shown) provided in the jacquard device 21 and set. Further, the fabric end portion 24 in which the warp yarn 26 is extended in a comb shape is placed on the joint loom 22 so as to be adjacent to the weft 27 that is inserted through the heald mail of the opening device.
[0040]
Subsequently, the previously prepared joining member 34, the first warp 23a from the end of the joint loom 22 that becomes the most advanced weft 28 in the formed joint, and the second weft 29 from the most advanced The second warp 23b from the end of the joint loom 22 to be formed is united with the weft 27 previously placed and placed on the opposite side of the fabric end 24, that is, on the tip of the joint. 23a (the first warp from the end when weaving the joint part) 23a and the second weft 29 from the leading edge (2 from the most advanced when weaving the joint part) The second warp 23b is set on the joint loom 22 without being inserted into the heald mail provided in the opening device of the joint loom 22. In addition, the joining member 34 inserts the first warp 23a from the end of the joint loom 22 into the position of the loop forming core wire 32 for engaging the main body weft at the time of its formation. The second warp 23b is inserted from the end of the joint loom 22 to the position of the second weft engagement loop forming core wire 33 from the front end of the main body.
[0041]
In FIGS. 1 and 2, an example in which the joint loop loom 22 is not inserted into the position of the joining loop forming core wire 31 when the joining member 34 is formed has been described. Alternatively, the yarn corresponding to the joining loop forming core wire 31 (indicated by a broken line in FIG. 1) may be inserted and set.
[0042]
Subsequently, the joint member is formed by locking the joining member 34 to the end of the fabric in the manner of Step I to Step IV described below.
[0043]
[Step I]
That is, in Step I of FIG. 2, the warps 23,... 23 when weaving by the joint loom 22 are opened in the illustrated opening state according to the fabric structure, and the openings (see FIG. 4) of the warps 23,. . In the fabric end 24, after inserting every other end of the warp 26 extending in a comb shape as the weft 25 (weft 25 a) when weaving with the joint loom 22, The joint loom 22 is wound counterclockwise from the upper side of the second warp 23b from the forefront.
[0044]
[Step II]
Subsequently, in Step II, the joint yarn is wound clockwise from the lower side of the first warp 23a from the end of the joint loom 22 and engaged with the joining member 34, and then pulled upward. That is, when the joining member 34 is formed, it is a loop formed around the loop leading core 32 for engaging the main body weft, and is locked to the first warp 23a from the end of the joint loom 22 The weft thread 25a is entangled with and engaged with the loop that has been wound, and is wound from the lower side of the first warp 23a from the end, and then pulled upward (corresponding to the portion of (1) in FIG. 1). .
[0045]
In Step II, the warps 23,... 23 are opened in the illustrated open state in accordance with the fabric structure, and the end of the weft 25a pulled up in Step I is located above the first warp 23a from the end in the joint loom 22. Winding clockwise, and then winding counterclockwise from the lower side of the second warp 23b from the end, and then weaving through the openings of the warps 23,. Proceed to the next step with the end pulled out from the surface of the fabric (corresponding to (2) in FIG. 1).
[0046]
[Step III]
In Step III, the open state shown in the figure is opened according to the fabric structure, the next weft 25b is inserted through the opening after the weft 25a previously woven in Step I and Step II, and the end of the weft 25b is placed on the surface of the fabric. Weave in the state pulled out from. In the opened state of III in this step, not all the warp yarns 23,... 23 are opened, and only a part of the warp yarns 24 on the fabric end 24 side necessary for weaving the weft yarn 25b is opened. Corresponds to (3) in FIG. 1).
[0047]
[Step IV]
Step IV is the same as Step I after one cycle. In FIG. 1, it can be seen that the weft yarn 25a woven in the previous step II and the weft yarn 25b woven in step III are woven in a partially aligned state (in FIG. 1, ▲ 4). ▼ part).
[0048]
By sequentially changing the opening state according to the fabric structure as described above, the wefts 25 (wefts 25a and 25b) when weaving by the joint loom 22 are woven corresponding to the fabric structure (plain weave structure in this example). Will be interwoven in the organization. That is, the woven structure of the woven fabric is the same except that the woven weft yarn 25a and the weft yarn 25b are woven in a state in which the respective tip portions are aligned (portion (4) in FIG. 1). In other words, it is woven with a woven structure corresponding to the woven structure of the fabric.
[0049]
Extra portions at the ends of the weft yarn 25a and the weft yarn 25b drawn out from the fabric surface are later adjusted and adjusted so as not to protrude from the fabric surface during use.
[0050]
In Step III, the position where the end of the weft thread 25b is pulled out from the surface of the fabric is located closer to the end of the fabric (the left side in FIGS. 1 and 2) than the position where the end of the weft thread 25a is pulled out from the surface of the fabric.
[0051]
As described above, a part of the warp 26 extending in a comb shape (that is, the weft 25a when weaving by the joint loom 22) is used as the joint weaving loom which becomes the most advanced weft 28 in the joint after forming. The first warp 23a from the end portion 22 is wound and folded, and then woven with a woven structure corresponding to the woven structure of the woven fabric (in this example, a plain woven structure), The remaining warp (ie, the weft 25b when weaving with the joint loom 22), and adjacent to the folded warp (ie, the weft 25a when weaving with the joint loom 22) (ie, the joint loom 22). The weft yarn 25b) when weaving is cut and removed from the most advanced weft to a predetermined position inside, that is, from the end of the fabric to a predetermined position on the side of the fabric body, and the remainder is woven structure corresponding to the woven structure of the fabric so It will be Komu Ri.
[0052]
In the description with reference to FIG. 1 and FIG. 2 described above, a part of the warps 26 extending in a comb shape (that is, the wefts 25a when weaving by the joint loom 22) is the most advanced in the joint portion after formation. Although an example in which only the first warp 23a from the end of the joint loom 22 serving as the weft 28 is wound around and turned back is shown, the present invention is not limited to this, and for example, as shown in FIGS. 16 and 17 As described above, around the first warp 23a from the end of the joint loom 22 that becomes the most advanced weft 28 in the formed joint, and the end of the joint loom 22 that becomes the second weft 29 from the most distal end. From the first weft yarn 28 and the second weft yarn 29 at the foremost end, the periphery of the first weft yarn 28b and the second weft yarn 29 at the front end are wound and turned back. It is also possible That. <Claim 9, Claim 10>
[0053]
Further, by partially changing the opening state of step II and / or step III in FIG. 2, the weft yarn 25a drawn from the fabric surface and the drawing positions of the ends of the weft yarn 25b are dispersed, and the woven weft yarn 25a As shown in FIG. 1, the portion woven with the weft 25b partially aligned (portion (4) in FIG. 1) may be dispersed in the width direction and the length direction of the fabric. This is preferable because it makes it possible to improve the strength and surface properties of the joint.
[0054]
Further, in the portion woven in the state where the wefted yarn 25a and the weft 25b are woven in a partially aligned state (portion (4) in FIG. 1), The length and position can be suitably selected as appropriate. In actual work, the opening state is cyclically switched by setting a woven structure pattern in advance in the opening device of the joint loom 22, for example, the jacquard device 21. It can be manufactured without requiring the labor of each operator.
[0055]
In the example shown in FIGS. 1 and 2, as shown in FIG. 5, the joining loop yarn 30 is arranged in the opposite direction around the joining loop forming core wire 31 and the loop forming core wire 32 for engaging the main body weft. One wound loop shape 34a formed by winding, as shown in FIG. 6, a joining loop forming core wire 31, a main body leading edge weft engagement loop forming core wire 32, and a second weft engaging second from the main body tip With respect to the loop forming core wire 33, the loop forming core wire 31 for joining and the loop forming core wire 32 for engaging the main body cutting edge weft are respectively opposite to each other in the opposite direction (8-shaped). FIG. 7 shows another wound loop shape 34b formed by winding around the second weft engagement loop forming core wire 33 from the front end of the main body in the opposite direction (shape of figure 8). It is an example of the industrial fabric joint using a joining member 34C configurations having wound loop shape 34c which is formed by mixing alternately, but the present invention is not limited thereto.
[0056]
For example, as shown in FIG. 15, the joining loop yarns 30 are arranged in opposite directions (eight-letter shape) around the joining loop forming core wire 31 and the body leading edge weft engagement loop forming core wire 32 shown in FIG. 5. ), The joining member 34A formed of only one type of wound loop shape 34a, and the one wound loop shape 34a and the other winding member 34A as shown in FIGS. 16 and 17, for example. An industrial fabric joint is formed using a joining member 34C having a wound loop shape 34c formed by sequentially mixing the wound loop shape 34b in a 1: 1, 1: 2 or 1: 3 ratio. Is also possible. <Claim 2>
[0057]
On the other hand, in the example shown in FIG. 1 and FIG. 2, a part of the warp 26 extending in the interdigital shape is made to have a frontmost weft 28 and a second weft 29 from the frontmost in the joint after forming. When the periphery of any one of these wefts is wound and folded, the periphery of any one of the frontmost weft 28 and the second weft 29 from the frontmost is wound, and the joining member 34 is joined. Although it is an example of the joint of the industrial textile fabric of the structure which makes it engage with the loop formation core wire (31 shown with a broken line in the figure), and turns it back, this invention is not limited to this.
[0058]
For example, as shown in FIG. 17, a part of the warp 26 extending in the interdigital shape is used as a weft of either the most distal weft 28 or the second most recent weft 29 in the joint portion after formation. A portion 36 that is wound around one of the frontmost weft 28 and the second weft 29 from the foremost and wound back together with the joining member 34C. A portion 37 that is folded back without being entangled with the joining member 34C by winding only around the weft of the most recent weft 28 and the second weft 29 from the foremost, over the entire width of the fabric, In accordance with the prescribed order and the number of parts, for example, it is possible to form a joint for an industrial fabric having a configuration in which the parts are folded back and forth alternately. <Claim 3 and Claim 4>
[0059]
Next, an example of forming a joining loop row by binding a yarn made of a synthetic resin monofilament or synthetic fiber yarn, which is different from the warp constituting the fabric 20, to both end portions 24 of the fabric 20 will be described below. The explanation is as follows.

[0089]
In the industrial fabric joint of the present invention, as described above, the joining member 34 having the joining loop row 40 formed by the joining loop yarn 35 different from the warp constituting the fabric is provided at both ends of the fabric. When joining to form the joining loop row 40, the joining loop yarn 35 made of a synthetic resin monofilament or synthetic fiber yarn different from the warp constituting the fabric is bound at each end of the fabric. As shown in FIG. 10, the joining member 34 includes the most advanced weft 28 and the second most preferred weft 29 as shown in FIG. Since it is attached to the two wefts while being wound and locked, for example, the conventional spiral wire 4 shown in FIGS. 21 to 23 is attached in a state where only the auxiliary core wire 5 is wound. As shown in FIG. 11, each loop of the spiral wire 4 that has become a problem in the joint is directed upward (indicated by a broken line in the drawing) or downward (not shown), and the direction in which each loop is attached is constant. When the loops of the spiral wires 4 at both ends of the fabric are meshed and joined to each other, the joining work may be hindered or the joining core wires may be inserted through the loops or may be leaked. There is no fear, the joining workability is remarkably improved, and quality problems can be avoided.
[0090]
In addition, in the industrial fabric joint of the present invention, as shown in FIG. 12, the joining member 34 or the joining loop yarn 35 is disposed in the opposite directions around the joining core wire 42 and the cutting edge weft 28. Since the structure is wound, when viewed from the direction perpendicular to the plane of FIG. 12, for example, the joining loop yarn 35 crosses in a figure 8 shape between the joining core wire 42 and the most distal weft 28. When the industrial fabric is used, the joining loop yarn 35 is pulled in the left-right direction in FIG. 12 by the tension applied in the warp direction of the fabric, and at the same time, the joining core wire 42 and the most distal weft 28 are joined to the joining loop yarn 35. Is tightened from around and pressed from above and below in the vertical direction of the paper.
[0091]
Similarly, as shown in FIG. 13, when viewed from the direction perpendicular to the plane of the drawing, for example, the joining loop yarn 35 intersects the joining core wire 42 and the leading edge weft 28 in the shape of an eight and the leading edge. Since the weft 28 and the second weft 29 from the most advanced weft are crossed in an 8-shape, the joining loop yarn 35 is formed by the tension applied in the warp direction of the fabric when the industrial fabric is used. At the same time as being pulled in the left-right direction in FIG. 13, the joining core wire 42, the most distal weft 28, and the second weft 29 from the most distal weft are tightened from around by the joining loop yarn 35, and the upper and lower sides in the vertical direction of the paper surface It will be pressed from the side.
[0092]
Therefore, the tension applied in the warp direction when the industrial fabric is used is so that the joining state of the entangled portion of the joining loop yarn 35 and the most advanced weft 28 or the second weft 29 from the most advanced weft is further strengthened. At the same time, the joining loop yarn 35 has a thickness dimension of the engaging portion or the binding portion of the joining loop yarn 35, that is, the joining loop yarn 35 against the second weft 29 from the most recent weft 28 or the most recent weft 29. The effect of acting to reduce the thickness dimension at the rotated portion or the thickness dimension at the portion joined by the joining core wire 42 can be obtained.
[0093]
Therefore, for example, depending on the selection of the wire rod or spiral shape of the spiral wire 4 to be used, which is a problem in the joint disclosed in Patent Document 1 described above, the thickness of the joint portion is thicker than the thickness of the fabric body. In addition, it is possible to prevent the occurrence of defects in product quality due to marking on a conveyed product such as wet paper (paper sheet) and to avoid the risk that the most advanced weft will move out in the width direction and come out.
[0094]
Furthermore, by selecting the materials and dimensions of the most advanced weft, loop yarn for joining, and core wire for joining, the joint part is made thin, and it is easy to occur when the canvas holds and winds the cylinder. Suppressing the bad quality of wet paper caused by a sudden rise and preventing wear deterioration of the same part.
[0095]
In addition, in the case of producing the industrial fabric joint of the present invention, a part of the warps 26 extending in the shape of a weave at the end of the fabric is used as the most advanced weft 28 and the second most from the most advanced. A weaving method using an opening device by means of a jacquard device 21, for example, as described above when weaving with a woven structure corresponding to the woven structure of the woven fabric, Alternatively, by using the joint loom 22 equipped with an opening device such as the jacquard device 21, the opening state can be cyclically switched according to a predetermined woven structure set in the opening device in advance. Necessary warp opening can be performed simply by operating the switch. By simply inserting the wefts during weaving of the joint into the warp opening, binding according to the specified weaving structure pattern is extremely simple and quick. Therefore, for example, the method disclosed in Patent Document 2 can greatly reduce labor and manpower at the time of manufacturing the joint portion compared to the work conventionally bound in the fabric weave. Become.
[0096]
In addition, according to the joint of the industrial fabric of the present invention, for example, a loop is formed when used for a long time under the use condition of high temperature and high tension, which is a problem in the joint disclosed in Patent Document 2. There is a risk that the fabric side folded portion 15 of the yarn will move between the warp yarn 11 and the weft yarn 12 at the weave 16 and move toward the joining loop 14 to loosen the loop forming yarn 13, and the end of the fabric end. Incorporation of loop forming yarn 13 by another yarn in addition to the woven structure causes a decrease in air permeability, adhesion of paper dust and other dirt substances, generation of clogging and clogging, and paper sheet separation caused by them Can be avoided.
[0097]
Furthermore, in the joint disclosed in, for example, Patent Document 2, a plurality of loop forming yarns 13 resulting from binding the loop forming yarns 13 up and down with respect to the arrayed wefts 12 at the ends of the fabrics. However, according to the present invention, there is a problem of troubles in product quality due to the trouble of adding the stitches using the yarn and the protrusion of the yarn end at the switching portion of the loop forming yarn 13. Since the joining loop row can be formed only by the joining member 34 or the joining loop yarn 35 made of continuous yarns of the book, there is no thread switching portion, and there are no problems caused by them. Become.
[0098]
For the yarn constituting the joining member 34 or the joining loop yarn 35 in the present invention, a synthetic resin monofilament or synthetic fiber yarn made of the same material as or different from the warp yarn 26 and / or the weft yarn 27 constituting the woven fabric. Articles can be used. For example, polyester monofilaments such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polytrimethylene terephthalate (PTMT) are easy to form in an appropriate cross-sectional shape, as well as tensile strength, hook strength, and dimensional stability. The mechanical performance such as property is also preferable. PET, particularly PET for industrial materials with improved hydrolysis resistance, particularly PET for papermaking dryer canvas is suitable.
[0099]
In addition, when the industrial fabric of the present invention is used as a papermaking dryer canvas, it is used in an atmosphere of high temperature and high humidity, and the joint portion travels when wound around a roll or the like compared to the fabric body. Stresses such as bending inside may be concentrated and a load larger than that of the main body may be applied, and wear is also easily received, and damage is easily caused from this portion. For this reason, the joining member 34 or the joining loop yarn 35, or the weft yarns (28, 29) near the joint tip portion, have higher heat resistance and / or wear resistance than the warp monofilaments constituting the fabric body. It is preferable to use an excellent yarn. The heat resistance is intended to have both heat and moisture resistance in addition to dry heat resistance.
[0100]
As a monofilament excellent in heat resistance, for example, polyether ether ketone (PEEK) or polyphenylene sulfide (PPS) can be used. As the monofilament having excellent wear resistance, among the PET for industrial materials with improved hydrolysis resistance, use a polyamide or the like in addition to PET having improved wear resistance using a high polymerization degree polymer. I can do it. In addition to monofilaments, it is also possible to use high-strength multifilaments, for example, yarns with improved wear resistance by applying and impregnating epoxy-based or polyamide-based resins to aromatic polyamide fibers. .
[0101]
In addition, it is preferable to use a thread (wire diameter) that is thinner than the warp 26 of the woven fabric body as the thread constituting the joining member 34 or the joining loop thread 35 in the present invention. It is possible to avoid the member 34 or the joining loop yarn 35 from coming out of the fabric surface in the thickness direction, thereby preventing the surface property of the fabric and preventing inadvertent product quality troubles. Furthermore, a thread having a thin or elliptical cross-sectional shape in the thickness direction can be used.
[0102]
Furthermore, it is preferable to use a high shrinkage yarn having a high shrinkage rate as the yarn constituting the joining member 34 or the joining loop yarn 35 in the present invention. For example, the weft 27 or warp yarn 26 constituting the woven fabric is used. It is also preferable to use a high shrinkage yarn having a larger shrinkage rate than the weft 27. That is, by using a high shrinkage yarn having a high shrinkage rate at the heat set processing temperature after the joint portion is formed, heat setting processing is performed after the joint portion is formed, and the joining loop forming core wire 41, the most advanced weft 28 and the most It is easy to form along the outer periphery of the second weft 29 from the tip weft, the surface property of the joint portion is good, and the core wire for inserting the joining core wire 42 for joining the fabric endlessly A joint part with good insertability can be formed, which is preferable. As the high shrinkage yarn having a large shrinkage rate, for example, in the case of PET, among the PET for industrial materials with improved hydrolysis resistance, 12% to 26% at 160 ° C., 14% to 30% at 180 ° C. Those having a dry heat shrinkage rate (free shrinkage) in the range of% can be used.
[0103]
As a fabric suitable for carrying out the present invention, a single-layer fabric, particularly an open mesh plain fabric, is suitable. That is, the joint of the present invention has a configuration in which the joining member 34 or the joining loop yarn 35 is wound around the joining core wire 42, the most distal weft 28, and the second most preferred weft 29 in the opposite directions. Therefore, for example, the bending of the joining loop yarn 35 coincides with the bending of the warp 26 of the plain weave structure, and therefore, it is preferable that no remarkable unevenness is generated. However, this does not prevent application to single-layer fabrics other than plain weave. In addition, the joint of the present invention can be applied to a single-layered fabric in which a thick yarn and a thin wire are mixed in the weft as disclosed in, for example, Japanese Patent Application Laid-Open No. 9-310291.
[0104]
Furthermore, the structure of the joint of the present invention can be applied to multilayer fabrics other than single layer fabrics. For example, FIG. 14 shows a 1/3 broken oblique weft double weaving fabric, in which a joining loop forming core wire 41, the most advanced weft 43 in the joint middle layer, and the second weft 44 from the foremost joint middle layer are added. In the same manner as described above for the joining loop forming core wire 41 and the added joint middle layer wefts 43 and 44, a conceptual cross section of the longitudinal section structure of the joint portion in which the joining loop yarn 35 is bound. FIG.
[0105]
For the cutting edge weft 43 and the cutting edge weft 44 from the cutting edge in the middle layer of the joint portion, a yarn having a material or thickness (wire diameter) different from that of the weft of the fabric body may be used. Of course, instead of binding the joining loop yarn 35, the joining member 34 may be attached.
[0106]
In the practice of the present invention, the joining member 34 is locked to both ends of the fabric, or the joining loop yarn 35 is bound to form a joining loop row, and then inserted at the time of weaving the joint portion. Applying heat-set processing to both ends of the fabric with the loop-forming core wire 41 for joining or another loop-forming core wire for heat-setting inserted in place thereof, stabilizing the shape of the joining loop by heat fixing, A joint portion having good surface properties and a good insertion property of the joining core wire in actual use can be obtained, which is preferable. Furthermore, the joining core wire 42 or a joining core wire for heat set different from that is inserted into a common hole formed by meshing the joining loop rows at both ends of the fabric, and an appropriate tension is applied in the length direction. It is more preferable to heat-set the both ends of the fabric in the added state to stabilize the shape by thermally fixing the shape of the joining loop.
[0107]
In the manner described above, at the both ends of the woven fabric, a part of the warp 26 extending in the interdigital shape is used as a cutting edge weft 28 and a cutting edge second weft at the joint after forming. 29 is wound around one of the wefts, folded back, woven with a woven structure corresponding to the woven structure of the fabric, and the remaining warp of the warp 26 extending in the interdigital shape, the folded warp When the warp yarns adjacent to each other are cut and removed from the frontmost weft 28 to a predetermined position inside, and the remaining portion is woven with a woven structure corresponding to the woven structure of the woven fabric, the warp yarn 26 extended in the interdigital shape is used. In addition to a method of weaving a part of the warp and the remaining warp of the interdigital warp 26 adjacent to the warp with the same woven structure as that of the woven fabric, in particular, Tip of warp to weave Incorporate in the vicinity of the part just a different weave and the other part is exactly the same weave, loose is woven's warp, it is possible to prevent or escape is near the tip of the warp woven.
[0108]
Further, a portion near the tip of the warp to be woven after the folding is a warp adjacent to the warp, and a portion from the foremost weft 28 to a predetermined position inside is cut and removed. By weaving so that it is in an aligned state from the cutting point to the required position on the side of the fabric body, that is, on the side opposite to the joint, the warp yarn to be woven after being folded by the tension associated with the warp when the fabric is used It is preferable because it can prevent slipping out. For example, the example shown in FIG. 1 and FIG. 2 described above is an example where four wefts, that is, two weaves of a plain weave structure are aligned.
[0109]
【Example】
Next, examples of the present invention will be described.
[0110]
[Table 1]

[0111]
The industrial fabric of the example, that is, the dryer canvas joint, was manufactured based on the specifications shown in Table 1.
[0112]
That is, the warp yarn 26 is made of PET having a good hydrolysis resistance, which is generally available as a raw yarn for a papermaking dryer canvas, a circular monofilament having a diameter of 0.80 mm, and the weft 27 is the same as the warp yarn. Using a monofilament with a circular cross section of 0.90 mm in diameter and made of a plain weave structure, heat-set using a known and commonly used apparatus and method, the warp density is 12.0 / 2.54 cm, A woven fabric body having a weft density of 12.0 / 2.54 cm was prepared.
[0113]
As shown in FIG. 3 (A), the created woven fabric body is cut into predetermined lengths and widths, and at both ends in the length direction, from the end of the woven fabric 20 as shown in FIG. 3 (B). By removing the weft 27 over a predetermined length on the inner side, the warp 26 was extended in a comb shape.
[0114]
The joint body loom 22 equipped with the jacquard device 21 shown in FIG. 4 can be opened up and down in accordance with a predetermined woven structure pattern in which the thread inserted into the mail of the heald is set on the crest plug card. I started. As shown in FIG. 4, first, a predetermined number of wefts 27 removed from the end of the fabric is used as a warp 23 when weaving the joint with the joint loom 22 to produce a joint loom. 22 opening device, that is, a heald mail (not shown) provided in the jacquard device 21 is inserted and set, and a joining loop forming core wire 41 (see FIG. 8) is set on the distal end side of the joint portion first. Further, the fabric main body 20 in which the warp yarn 26 is extended in a comb shape is set next to the warp yarn 23, which is adjacent to the warp yarn 23 when weaving by the joint loom 22, and the warp yarn 26 is extended in a comb shape. Adjacent to the warp 23 when weaving with the joint loom 22, it was placed on the opposite side of the joining loop forming core wire 41.
[0115]
The weft 28 that is the most advanced in the joint after forming, that is, the second warp 45b from the end of the joint loom 22, is made of the same material as the warp 26 of the fabric body and has a circular cross-section monofilament having a diameter of 0.70 mm. Using. A circular stainless steel wire having a diameter of 0.60 mm was used for the joining loop forming core wire 41, that is, the warp 45a at the end of the joint loom 22. Further, the joining loop yarn 35 is a PET having a good hydrolysis resistance, which is generally available as a raw yarn for a papermaking dryer canvas, different from the warp 26 constituting the woven fabric body. A high-shrinkage shrinkage rate of 12.3% at 160 ° C. and a circular monofilament having a diameter of 0.50 mm were used.
[0116]
As the wefts in the joint loom 22, the warp 26 extending in the interdigital shape constituting the main body of the fabric is used, and each warp 26 extending in the interdigital shape is separated from the end in the joint loom 22 by two. The second warp yarn 45b was wound and turned up, and then woven according to the plain weave structure of the fabric body.
[0117]
Each time the warp 26 extending in the interdigital shape is used as the weft 25 in the joint loom 22, the loop yarn for joining is wound every time it is wound around the second warp 45b from the end of the joint loom 22. 35 is wound around the joining loop forming core wire 41 to form a joining loop and then folded back to extend to the position of the second warp 45b from the end of the joint loom 22, and then the joint loom 22 Is wound around the second warp 45b from the end in the direction opposite to the winding direction to the joining loop forming core wire 41 and is also entangled with the folded portion of the warp 26 extending in the interdigital shape. After that, the wire is extended to the position of the joining loop forming core wire 41, and further wound around the joining loop forming core wire 41 in the same winding direction as before to form a joining loop, and then folded back. Then, the joint loom 22 is wound in the direction opposite to the winding direction to the joining loop forming core wire 41 on the upper side (front side in FIG. 1) of the second warp 45b from the end of the joint loom 22, and further the joint loom 22 to the position of the third warp 45c from the end portion, and further, around the third warp 45c from the end portion of the joint loom 22 is wound in the same direction as the winding direction to the joining loop forming core wire 41. Next, the winding direction from the end of the joint loom 22 to the third warp 45c is below the second warp 45b from the end of the joint loom 22 (the back side in FIG. 1). And then extending to the position of the joining loop forming core wire 41, and further winding around the joining loop forming core wire 41 in the same winding direction to form a joining loop and then turning back. . The above operation is repeated over the width direction of the fabric, and the joining loop yarn 35 is joined to the joining loop forming core wire 41, the second warp yarn 45b from the end of the joint loom 22, and the joint to each of both ends of the fabric. A joining loop row 40 composed of a number of joining loops was formed by binding to the third warp 45c from the end of the loom 22.
[0118]
Further, after heat-set processing is performed on the portion where the joining loop yarn 35 is bound and the joining loop row 40 to stabilize the size and shape, the joining loop forming core wire 41 is connected to the joining loop row 40. To make an industrial fabric, i.e., a fabric with a dryer canvas joint.
[0119]
The time required for forming the joint according to the above is continuous while the loop-forming yarn 13 made of a thin, high-strength yarn is folded between the warp yarns 11 and 11 from the conventional joint shown in FIG. Is approximately 1/5 of the time required for forming the joint in which the loop 14 for joining is formed by the loop forming yarn 13 at the folded portion of the end, and the work time required for forming the joint is Significantly shortened.
[0120]
This woven fabric was put into a cutter machine of a papermaking machine, the loops for joining at both ends of the woven fabric were alternately meshed, and a joining core wire was inserted into a common hole formed by meshing, and used as an endless woven fabric. The workability of meshing the joining loop rows and the workability of inserting the joining core wire were extremely good.
[0121]
Further, when using the fabric, paper dust and other soiling substances are prominent on the portion where the joining loop yarn 35 is bound, or on the portion where the warp 26 constituting the fabric body is folded and woven according to the plain weave structure of the fabric body. Adhesion and accumulation were not observed, and there was no operational trouble due to a decrease in the suction performance of the paper sheet due to it.
[0122]
