Description

本発明は、接合用芯線、接合用具、リードワイヤー、製紙用シームフェルト及びその接合方法に関する。更に詳しくは、有端状製紙用織物の長手方向の両端を接合して無端状にした製紙用シームフェルト及びその接合方法、並びに、製紙用シームフェルトの接合に用いる接合用芯線、接合用具、リードワイヤーに関する。 The present invention relates to a core wire for joining, a joining tool, a lead wire, a seam felt for papermaking, and a method for joining the same. More specifically, the seam felt for papermaking and its joining method, in which both ends in the longitudinal direction of the woven fabric for papermaking are joined to form an endless shape, and the core wire, joining tool, and lead for joining used for joining the seam felt for papermaking. Regarding wires.

従来、製紙用シームフェルトには、有端状製紙用織物の長手方向の両端を接合して無端状にする製紙用シーム付き織物が用いられている。
この製紙用シーム付き織物は、有端状製紙用織物の一端側に設けられた接合用ループの内孔と、有端状製紙用織物の他端側に設けられた接合用ループの内孔と、が幅方向に重なるように整列させて形成される接合用ループ同士の共通孔に、接合用芯線を挿通することによって行われるのが通常である(例えば、特許文献1参照。)。
Conventionally, as the seam felt for papermaking, a woven fabric with a seam for papermaking has been used in which both ends in the longitudinal direction of the woven fabric for papermaking are joined to form an endless shape.
This woven fabric with seams for papermaking includes an inner hole of a joining loop provided on one end side of the woven fabric for endped papermaking and an inner hole of a joining loop provided on the other end side of the woven fabric for endped papermaking. , Are usually formed by inserting a joining core wire into a common hole between joining loops formed by arranging them so as to overlap each other in the width direction (see, for example, Patent Document 1).

また、湿紙のプレス工程において、大量の脱水が必要なパートでは、高い搾水性を確保するために、空隙容積を大きくした多重織構造の基布が用いられることがある。
特許文献1に記載の製紙用シーム付き織物では、4重織構造からなり、厚さ方向上下2段の2重織それぞれの端部にループ列を形成して、それぞれのループ列を分離可能にして、接合作業の効率化を図っている。
Further, in the wet paper pressing process, in a part requiring a large amount of dehydration, a base cloth having a multi-woven structure having a large void volume may be used in order to ensure high water squeezing.
The woven fabric with seams for papermaking described in Patent Document 1 has a quadruple weave structure, and loop rows are formed at the ends of each of the two upper and lower double weaves in the thickness direction so that the loop rows can be separated. We are trying to improve the efficiency of joining work.

製紙用フェルトは、製紙マシンにおいて、プレスロールと複数本のロールに装着され、プレスロールの回転により走行する。この時、走行姿勢を維持するための装置の一部を製紙用フェルトの側面に接触させる場合がある。一般的に、この接触により製紙用フェルトの側面は擦られ摩耗する。また、製紙用シームフェルトの場合、挿通された接合用芯線の両端部について、走行中に、接合用ループ内に引き込まれないような処置がなされている。例えば、織物の側面から飛び出た接合用芯線の端部を結節してコブ状にしたりする。コブがループの内孔よりも大きければ引き込まれることが防止される。この時、結節が解けないことや、前述の装置との摩擦による結節部の破断のないことが重要となる。また、結節させる方法の他に、接合用芯線の端部を折り返して、噛み合わせたループの外側の隙間に挿通させる方法や織物に縫い付ける方法もある。この場合においても前述の装置との摩擦による折り返し部の摩耗は致命的になるので、織物の側面より折り返し部が飛び出ることは避けなければならない。織物のシーム部端部に三角形の切り込みを入れ、接合用芯線が織物の側面から飛び出さないような方法もあるが、切り込みを入れると織物の糸を切断することになり、切断された糸が抜け出すことがあるため好ましくない。
ここで、ループ径が大きい場合、挿通させる接合用芯線の本数が多くなりかつ構成する糸の直径が大きくなるので、結節のコブは大きくなり、糸剛性が高くなるため解けやすくなる。接合用芯線を折り返す場合においては、織物の側面から飛び出す部分が大きく出っ張るので擦られやすくなってしまう。
The felt for papermaking is attached to a press roll and a plurality of rolls in a papermaking machine, and runs by the rotation of the press rolls. At this time, a part of the device for maintaining the running posture may be brought into contact with the side surface of the papermaking felt. Generally, this contact rubs and wears the sides of the papermaking felt. Further, in the case of papermaking seam felt, measures are taken so that both ends of the inserted joining core wire are not drawn into the joining loop during traveling. For example, the end portion of the joining core wire protruding from the side surface of the woven fabric is knotted to form a bump shape. If the bump is larger than the inner hole of the loop, it will be prevented from being pulled in. At this time, it is important that the nodule cannot be unraveled and that the nodule is not broken due to friction with the above-mentioned device. In addition to the method of knotting, there is also a method of folding back the end of the core wire for joining and inserting it into a gap outside the meshed loop, or a method of sewing to a woven fabric. Even in this case, the wear of the folded portion due to friction with the above-mentioned device becomes fatal, so it is necessary to avoid the folded portion protruding from the side surface of the woven fabric. There is also a method of making a triangular notch at the end of the seam part of the woven fabric so that the core wire for joining does not protrude from the side of the woven fabric. It is not preferable because it may come out.
Here, when the loop diameter is large, the number of connecting core wires to be inserted is large and the diameter of the constituent threads is large, so that the hump of the nodule is large and the thread rigidity is high, so that it is easy to unravel. When the core wire for joining is folded back, the portion protruding from the side surface of the woven fabric protrudes greatly, so that it is easily rubbed.

また、従来、シーム部の接合には、リードワイヤーと呼ばれる細い線材の後端に接合用芯線(糸の束)が固定されて一体化した用具を用いる(特許文献2参照。)。
例えば、図18に示すように、接合用具95は、接合用芯線91をリードワイヤー92の筒状部に内挿接着して形成し、先端部から接合用ループ同士の共通孔に、接合用芯線を挿通する。
更に、細い線材の後端を縫い針のような孔状にしたリードワイヤーも提案されている(特許文献3参照。)。このリードワイヤーは、細い線材の後端を縫い針のような孔状にして形成され、孔部に接合用芯線を掛け止めして、先端側から前記共通孔に挿入して接合用芯線を挿入することができる。ループ径が小さな場合、針孔で折り返された部分の糸の膨らみがループ径より大きくなり、スムーズな挿通が阻害される。
Further, conventionally, for joining the seam portion, a tool called a lead wire in which a joining core wire (bundle of threads) is fixed to the rear end of a thin wire rod and integrated is used (see Patent Document 2).
For example, as shown in FIG. 18, the joining tool 95 is formed by interpolating and adhering the joining core wire 91 to the tubular portion of the lead wire 92, and forming the joining core wire into a common hole between the joining loops from the tip portion. Is inserted.
Further, a lead wire in which the rear end of a thin wire has a hole shape like a sewing needle has also been proposed (see Patent Document 3). This lead wire is formed by forming the rear end of a thin wire into a hole shape like a sewing needle, hooking the joining core wire into the hole, inserting it into the common hole from the tip side, and inserting the joining core wire. can do. When the loop diameter is small, the swelling of the thread at the portion folded back by the needle hole becomes larger than the loop diameter, and smooth insertion is hindered.

ここで、多重織の製紙用シームフェルトであっても、外側の基布(製紙用織物)同士の糸を用いてシングルシームにしたい場合には、必然的にループ径が大きくなる。
ここで、接合用芯線の太さ、本数はループ径の大きさによって調整することになるが、ループ径が大きくなれば必然的に、接合用芯線の本数が多くなり、接合用芯線を構成する糸径は大きいものが選択される。接合用芯線の本数が多くなれば、ループ孔への挿通作業も手間取ることになる。更に、接合用芯線の本数が多くなりかつ接合用芯線の糸径が大きくなると、束としての糸の曲げ剛性が高くなり、結果として接合用芯線の両端部を基布端部に固定するための接合用芯線の折り返し作業、あるいは接合用芯線の結節作業が困難となる。例えば、図17に示すように、従来の接合用芯線91は、有端状製紙用織物の一端側3、他端側4を接合するに際して、端部から引き出されるとほうき状となり、特に10本を超える場合は、その剛性から処置が困難である。
Here, even in the case of multi-woven papermaking seam felt, if it is desired to make a single seam by using threads of outer base fabrics (papermaking fabrics), the loop diameter is inevitably large.
Here, the thickness and number of the joining core wires are adjusted according to the size of the loop diameter, but as the loop diameter increases, the number of joining core wires inevitably increases to form the joining core wire. A thread with a large thread diameter is selected. If the number of core wires for joining is increased, it will take time and effort to insert the core wires into the loop holes. Further, when the number of the joining core wires is increased and the thread diameter of the joining core wires is increased, the bending rigidity of the threads as a bundle is increased, and as a result, both ends of the joining core wires are fixed to the base cloth end portions. It becomes difficult to fold back the joining core wire or knot the joining core wire. For example, as shown in FIG. 17, the conventional bonding core wire 91 becomes broom-shaped when pulled out from the end portion when joining one end side 3 and the other end side 4 of the end-shaped papermaking woven fabric, and particularly 10 wires. If it exceeds, it is difficult to treat due to its rigidity.

また、特許文献2に記載のリードワイヤーは、リードワイヤーと接合用芯線が一体化しているので取り外しができず、挿通後、挿通させた部分を差し引いて切断されるので、挿通ごとに接合用芯線は短くなり、必要長さを確保できなくなった時点で廃棄される消耗品となってしまう。
更に、特許文献3に記載のリードワイヤーは、線材の後端を孔状にするために、後端を熔接することになるが、接合用芯線を挿通する時の引っ張り力は大きいので、熔接部が破壊されることが多々ある。
Further, the lead wire described in Patent Document 2 cannot be removed because the lead wire and the core wire for joining are integrated, and after the insertion, the inserted portion is subtracted and cut. Therefore, the core wire for joining is cut for each insertion. Becomes shorter and becomes a consumable item that is discarded when the required length cannot be secured.
Further, in the lead wire described in Patent Document 3, the rear end is welded in order to make the rear end of the wire into a hole shape, but since the pulling force when inserting the joining core wire is large, the welded portion Is often destroyed.

本発明は、上記現状に鑑みてなされたものであり、製紙用シームフェルトにおいて、接合用のループ径が大きな場合であっても、効率的に接合可能な製紙用シームフェルトの接合用芯線及びその接合用具並びに製紙用シームフェルト及びその接合方法とその接合方法に用いるリードワイヤーを提供することを目的とする。 The present invention has been made in view of the above situation, and in a papermaking seam felt, a core wire for joining a papermaking seam felt that can be efficiently joined even when the loop diameter for joining is large, and a core wire thereof. It is an object of the present invention to provide a joining tool, a seam felt for papermaking, a joining method thereof, and a lead wire used for the joining method.

The joining core wire used for joining the seam felt for papermaking of the present invention is formed in the inner hole of the joining loop provided on one end side of the woven fabric for endped papermaking and on the other end side of the woven fabric for endned papermaking. It is used by inserting the inner hole of the provided joining loop into the communication hole formed by aligning the inner hole in the width direction.

ここで示される事項は例示的なものおよび本発明の実施形態を例示的に説明するためのものであり、本発明の原理と概念的な特徴とを最も有効に且つ難なく理解できる説明であると思われるものを提供する目的で述べたものである。この点で、本発明の根本的な理解のために必要である程度以上に本発明の構造的な詳細を示すことを意図してはおらず、図面と合わせた説明によって本発明の幾つかの形態が実際にどのように具現化されるかを当業者に明らかにするものである。 The matters shown here are for exemplifying and exemplifying embodiments of the present invention, and are considered to be the most effective and effortless explanations for understanding the principles and conceptual features of the present invention. It is stated for the purpose of providing what seems to be. In this regard, it is not intended to show structural details of the invention beyond a certain degree necessary for a fundamental understanding of the invention, and some embodiments of the invention are provided by description in conjunction with the drawings. It is intended to clarify to those skilled in the art how it is actually realized.

[1]接合用芯線
前記「接合用芯線」は、例えば図9(a)に示すように、有端状製紙用織物1aの長手方向の両端(一端側3、他端側4)を接合して無端状の製紙用シーム付き織物1Aにするために用いられる。
この接合は、有端状製紙用織物1aの一端側3と、前記有端状製紙用織物1aの他端側4によって接合形成された連通孔50に、接合用芯線10Cを挿通することによって行われる。
[1] Joining core wire As shown in FIG. 9A, for example, the "joining core wire" joins both ends (one end side 3, the other end side 4) of the woven fabric 1a for endped papermaking in the longitudinal direction. It is used to make a woven fabric 1A with an endless paper seam.
This joining is performed by inserting the joining core wire 10C into the communication hole 50 formed by joining the one end side 3 of the woven fabric 1a for endped papermaking and the other end side 4 of the woven fabric 1a for endned papermaking. Will be.

接合用芯線は、ループ状に巻回された繊維を束ねたループ状繊維束を含む。
前記「ループ状繊維束」は、ループ状に巻回された繊維を束ねたループ状繊維束であれば、特に限定はなく、後述のように、コイル状繊維束、片側ループ状繊維束、又はコイル折り畳み状繊維束などを含む。
接合用芯線を連通孔へ挿通する際の作業性を向上させることができる。即ち、引き伸ばした状態で、長尺である1本の繊維を、短い長さにまとめようとした場合、繊維をループ状に巻回して束ねる方法以外にも、例えば、折り畳んで束ねる方法等が存在する。しかしながら、長尺な繊維を折り畳んで束ねると、束ねた状態にある繊維束の一端側には、複数のループが同形状にまとまった一塊のループ塊が形成されるものの、他端側は、ばらばらになった複数のループが形成されてしまう。すると、この他端側の複数のループを、同形状にまとまった一塊のループ塊に形成するという手間を要するととともに、ループ塊を形成すると繊維束の中央付近にねじれやたるみを生じてしまうことになる。このようなねじれを生じると、その箇所のみ束の太さが大きくなってしまうことになり、連通孔へ挿通の障害となり得る。
The bonding core wire includes a loop-shaped fiber bundle in which fibers wound in a loop shape are bundled.
The "loop-shaped fiber bundle" is not particularly limited as long as it is a loop-shaped fiber bundle in which fibers wound in a loop shape are bundled, and as described later, a coiled fiber bundle, a one-sided loop-shaped fiber bundle, or a one-sided loop-shaped fiber bundle. Includes coil folding fiber bundles and the like.
Workability when inserting the connecting core wire into the communication hole can be improved. That is, when trying to bundle one long fiber into a short length in a stretched state, there is, for example, a method of folding and bundling the fibers in addition to the method of winding the fibers in a loop and bundling them. do. However, when long fibers are folded and bundled, a single loop mass in which a plurality of loops are grouped in the same shape is formed on one end side of the bundled fiber bundle, but the other end side is separated. Multiple loops are formed. Then, it takes time and effort to form the plurality of loops on the other end side into a single loop mass having the same shape, and when the loop mass is formed, twisting and sagging occur near the center of the fiber bundle. become. When such a twist occurs, the thickness of the bundle becomes large only at that portion, which may hinder the insertion into the communication hole.

この点、ループ状に巻回された繊維束であるループ状繊維束は、左右の両端ともに、複数のループが同形状にまとまった一塊のループ塊が各々形成され、尚且つ、繊維束の中央部にねじれやたるみを生じることがない。従って、両端のループ塊を得やすく、更には、繊維束を全体としてほぼ同じ太さに揃えることができるため、連通孔への挿通性を良くすることができる。
即ち、後述するように、引出工程及び引戻工程において、どちらの方向へループ状繊維束を移動させても連通孔内で繊維束がばらばらに分離されないよう、補助芯線やリードワイヤーを設けることが可能である。
In this respect, in the loop-shaped fiber bundle, which is a fiber bundle wound in a loop shape, a single loop mass in which a plurality of loops are grouped in the same shape is formed at both the left and right ends, and the center of the fiber bundle is formed. No twisting or sagging in the part. Therefore, it is easy to obtain loop lumps at both ends, and further, since the fiber bundles can be made to have substantially the same thickness as a whole, the passability into the communication hole can be improved.
That is, as will be described later, in the drawing step and the pulling step, an auxiliary core wire or a lead wire may be provided so that the fiber bundle is not separated in the communication hole regardless of which direction the loop-shaped fiber bundle is moved. It is possible.

尚、芯線本体は、ループ状繊維束のみからなることが好ましいが、例えば、他の繊維を含んでもよい。
また、「接合用芯線」は、芯線本体のみからなってもよいし、後述するように、芯線本体に補助芯線が取り付けられた状態、即ち、芯線本体と補助芯線とを含んでもよい。例えば、図1に示す接合用芯線10Aは、ループ状繊維束(コイル状繊維束)11のみからなる。即ち、芯線本体がループ状繊維束11のみからなる例である。他方、図2に示す接合用芯線10Bは、芯線本体(ループ状繊維束11)と補助芯線12とからなる例である。また、図2では、芯線本体(ループ状繊維束11)はループ状繊維束のみからなる。
The core wire body is preferably composed of only loop-shaped fiber bundles, but may contain other fibers, for example.
Further, the "joining core wire" may consist of only the core wire main body, or may include a state in which the auxiliary core wire is attached to the core wire main body, that is, the core wire main body and the auxiliary core wire, as will be described later. For example, the bonding core wire 10A shown in FIG. 1 is composed of only a loop-shaped fiber bundle (coil-shaped fiber bundle) 11. That is, this is an example in which the core wire body is composed of only the loop-shaped fiber bundle 11. On the other hand, the joining core wire 10B shown in FIG. 2 is an example including a core wire main body (loop-shaped fiber bundle 11) and an auxiliary core wire 12. Further, in FIG. 2, the core wire main body (loop-shaped fiber bundle 11) is composed of only the loop-shaped fiber bundle.

ループ状繊維束は、多数回巻回した繊維の束であり、巻回数は特に限定はないが、ループ径に応じて巻回数を定めることができ、4〜20巻であることが好ましく、10〜15巻であることが更に好ましい。本実施形態に係るループ状繊維束11は、4巻であり、8本の繊維束を形成している。
繊維の種類は特に限定はなく、モノフィラメントの単糸又は撚糸、マルチフィラメントであってもよいが、これらの中でもモノフィラメントの単糸であることが好ましい。
モノフィラメントの単糸であれば、その径は、0.2〜0.6mmであることが好ましく、0.3〜0.5mmであることが更に好ましい。
ループ状繊維束を構成する糸の材質は特に限定はないが、ポリアミドなどの高強度な合成樹脂材料からなるモノフィラメント糸であることが好ましい。
The loop-shaped fiber bundle is a bundle of fibers wound many times, and the number of windings is not particularly limited, but the number of windings can be determined according to the loop diameter, and the number of windings is preferably 4 to 20. It is more preferable that the volume is ~ 15. The loop-shaped fiber bundle 11 according to the present embodiment has four rolls and forms eight fiber bundles.
The type of fiber is not particularly limited and may be a monofilament single yarn, a twisted yarn, or a multifilament, but among these, a monofilament single yarn is preferable.
In the case of a monofilament single yarn, the diameter thereof is preferably 0.2 to 0.6 mm, more preferably 0.3 to 0.5 mm.
The material of the yarn constituting the loop-shaped fiber bundle is not particularly limited, but a monofilament yarn made of a high-strength synthetic resin material such as polyamide is preferable.

ループ状繊維束11は、前記有端状製紙用織物1aの幅長さよりも短くすることができる。即ち、有端状製紙用織物1aの長手方向の一端3における幅(3a−3a縁部間の幅)、及び、有端状製紙用織物1aの長手方向の他端4における幅(4a−4a縁部間の幅)より短くできる。このように、ループ状繊維束の束長さが、有端状製紙用織物1aの幅長さより短い場合、適切な紙抄き幅にループ状繊維束11を設定することができ、幅方向両端には、補助芯線として縁部に固定しやすい糸を用いることができる。即ち、図7及び図8に例示するように、有端状製紙用織物1aの縁部(3a、4a)から、補助芯線12及び13が飛び出さないように設置することができる。
また、ループ状繊維束の束長さは、有端状製紙用織物の幅長さ以下としたうえで、更に、抄き幅以上にできる。即ち、織物(図7の符号1A、図8の符号2)の幅のうち、実際に紙抄きに供される領域幅より、ループ状繊維束の束長さを大きくすることができる。この場合、図7に示す結び目(12c、13c)、縫い込み部(12d、13d)、図8に示す結び目(12c、13c)等の補助芯線12及び13に起因するイレギュラーな凹凸を抄き幅の外側へ設置できる。このため、紙のマーク等の抄紙への影響を防止できる。
The loop-shaped fiber bundle 11 can be shorter than the width and length of the end-shaped papermaking woven fabric 1a. That is, the width at one end 3 of the woven fabric 1a in the longitudinal direction (width between the edges of 3a-3a) and the width at the other end 4 of the woven fabric 1a in the longitudinal direction (4a-4a). It can be shorter than the width between the edges). As described above, when the bundle length of the loop-shaped fiber bundle is shorter than the width length of the woven fabric 1a for end-shaped papermaking, the loop-shaped fiber bundle 11 can be set to an appropriate papermaking width, and both ends in the width direction. A thread that can be easily fixed to the edge can be used as the auxiliary core wire. That is, as illustrated in FIGS. 7 and 8, the auxiliary core wires 12 and 13 can be installed so as not to protrude from the edges (3a, 4a) of the woven fabric for endped papermaking 1a.
Further, the bundle length of the loop-shaped fiber bundle can be set to be equal to or less than the width of the end-shaped paper-making woven fabric, and further set to be equal to or larger than the width of the paper. That is, among the widths of the woven fabric (reference numeral 1A in FIG. 7, reference numeral 2 in FIG. 8), the bundle length of the loop-shaped fiber bundle can be made larger than the region width actually used for papermaking. In this case, irregular irregularities caused by the auxiliary core wires 12 and 13 such as the knots (12c, 13c) shown in FIG. 7, the sewn portions (12d, 13d), and the knots (12c, 13c) shown in FIG. 8 are drawn. Can be installed outside the width. Therefore, it is possible to prevent the influence of the paper mark and the like on the papermaking.

図2に示す接合用芯線10Bのように、前記ループ状繊維束11を、前記連通孔50に挿通した状態で固定するように、ループ状繊維束11の一端11a側に補助芯線12を備えることができる。
補助芯線12の材質は特に限定はないが、ループ状繊維束11を連通孔50内に固定し、縁部に縫い込み等により固定しやすいことが好ましい。例えば、異形断面繊維のマルチフィラメントとすることができる。異形断面繊維のマルチフィラメントである場合には、円形断面繊維のマルチフィラメントに比べ、結び目が解け難い。また、織物の縁部に糸を縫い付けて固定する場合、摩擦抵抗により解れにくく、更に接着剤で固定をより強固にする場合には、接着剤成分のアンカー効果が発現しやすくなるメリットがある。
また補助芯線12は、モノフィラメント及び/又は紡績糸の撚糸からなることができる。モノフィラメントの撚糸、紡績糸の撚糸、モノフィラメントと紡績糸の混合糸などを採用でき、これらであれば、結び目が解け難く、シーム部の幅方向の縁部をより強固にすることができる。
図2に示す補助芯線12は、モノフィラメントの撚糸に紡績糸の撚糸がカバーリングされた混合糸からなり、ある程度剛性を保持しつつ、縁部への固定しやすさを備えている。
An auxiliary core wire 12 is provided on one end 11a side of the loop-shaped fiber bundle 11 so that the loop-shaped fiber bundle 11 is fixed in a state of being inserted into the communication hole 50 as in the bonding core wire 10B shown in FIG. Can be done.
The material of the auxiliary core wire 12 is not particularly limited, but it is preferable that the loop-shaped fiber bundle 11 is fixed in the communication hole 50 and easily fixed to the edge portion by sewing or the like. For example, it can be a multifilament of irregular cross-section fibers. In the case of the multifilament of the irregular cross-section fiber, the knot is hard to be untied as compared with the multifilament of the circular cross-section fiber. Further, when the thread is sewn to the edge of the woven fabric and fixed, it is difficult to unravel due to frictional resistance, and when the fixing is further strengthened with an adhesive, there is an advantage that the anchor effect of the adhesive component is easily exhibited. ..
Further, the auxiliary core wire 12 can be made of a monofilament and / or a twisted yarn of a spun yarn. Plyed monofilament yarn, twisted spun yarn, mixed yarn of monofilament and spun yarn, and the like can be adopted, in which the knot is difficult to untie and the edge portion in the width direction of the seam portion can be further strengthened.
The auxiliary core wire 12 shown in FIG. 2 is made of a mixed yarn in which a twisted yarn of a spun yarn is covered with a twisted yarn of a monofilament, and has a certain degree of rigidity and is easy to fix to an edge portion.

前記「製紙用シームフェルト」は、有端状製紙用織物の長手方向の両端が接合されて無端状にされた製紙用シーム付き織物にバット繊維層を積層一体化して製造される。
以下の説明において、バット繊維層を省略した方が説明が判り易いため、あえてバット繊維層については記載を省略している。
織物の織組織は特に限定はなく、2重織、3重織、4重織、1重織を2枚重ねたラミネート、1重織と2重織を重ねたラミネート、2重織を2枚重ねたラミネート、織物ではなく有孔のウレタンシートと2重織を重ねたラミネートタイプにすることができる。
本発明に係る一例としての製紙用シーム付き織物1Aを模式的に記載した図6及び、図7に示す。
図6(a)に示すように、製紙用シーム付き織物1Aは、第1経糸51、第2経糸52、第3経糸53、第4経糸54が厚さ方向に重ねられ、これらと交絡する緯糸61、62、及び接結糸63から形成された4重織の織物組織をなしている。

[2] Papermaking seam felt The above-mentioned "papermaking seam felt" is made by laminating and integrating a bat fiber layer on a papermaking seam-attached woven fabric in which both ends in the longitudinal direction of an endped papermaking woven fabric are joined to form an endless shape. Manufactured.
In the following description, since it is easier to understand the explanation if the butt fiber layer is omitted, the description of the butt fiber layer is intentionally omitted.
The weaving structure of the woven fabric is not particularly limited, and two layers of double weave, triple weave, quadruple weave, and one layer weave are laminated, and one layer and two layers of double weave are laminated. It is possible to make a laminated type in which a perforated urethane sheet and a double weave are laminated instead of a laminated laminate or a woven fabric.
FIG. 6 and FIG. 7 schematically show a woven fabric 1A with a seam for papermaking as an example according to the present invention.
As shown in FIG. 6A, in the woven fabric 1A with a seam for papermaking, the first warp 51, the second warp 52, the third warp 53, and the fourth warp 54 are overlapped in the thickness direction and are entangled with these wefts. It has a quadruple woven fabric structure formed from 61, 62, and confounding yarn 63.
Joining loops 30 and 40 are formed at both ends in the longitudinal direction by folding back the first warp 51 and the fourth warp 54 of the first to fourth warp 51 to 54. Of these, the inner hole 30h of the joining loop 30 on one end side 3 of the woven fabric 1A for endped papermaking and the inner hole 40h of the joining loop 40 on the other end side 4 of the woven fabric 1a for endned papermaking are overlapped with each other. As a result, the communication hole 50 is formed.
That is, a large number of joining loops 30 and 40 are arranged in the width direction of the woven fabric to form a loop row. Then, the joining loops 30 and 40, which are the joining partners, and the inner holes 30h and 40h of each other are aligned to form the communication hole 50.

経糸51〜54、緯糸61、62の種類は、特に限定はないが、ポリアミドなどの高強度な合成樹脂材料からなるモノフィラメント糸であることが好ましい。なお、接合用ループ直近においては、多数のフィラメントを束ねたマルチフィラメント糸からなる緯糸を織り込んで、接合用ループの基部の締め付けを緩和して、接合用ループの形態を適正化することもできる。 The types of warp yarns 51 to 54 and weft yarns 61 and 62 are not particularly limited, but are preferably monofilament yarns made of a high-strength synthetic resin material such as polyamide. In the immediate vicinity of the joining loop, a weft yarn made of a multifilament yarn in which a large number of filaments are bundled can be woven to relax the tightening of the base of the joining loop and optimize the shape of the joining loop.

そして、連通孔50内に挿通された接合用芯線10Cを備えている。
接合用芯線10Cは、図7に示すように、ループ状繊維束11と、ループ状繊維束11の両端に固定された補助芯線12、13とからなる。ループ状繊維束11、補助芯線12、13の構成、作用効果については前述の通りである。
補助芯線12、13は、有端状製紙用織物1aの縁部3a、4aの耳部35に瘤状に結び目12c、13cを形成し、更に織物に縫い込んだ縫い込み部12d、13dを有する。縫い込み部12d、13d部に接着剤を塗布することで更に強固に固定することができる。補助芯線が紡績糸又は紡績糸とモノフィラメントの混合糸の場合は、特に接着性がよいため、接着効率が特に優れている。
耳部35は、縁部3a、4aの内方に切込み形成されており、結び目12c、13cが製紙用シーム付き織物1Aの幅から、はみ出さないことが好ましい。
なお、接合用芯線の本数が多く構成する糸径が大きい場合であっても、製紙用シーム付き織物1Aの幅からはみ出すのは、補助芯線12、13であり、補助芯線12、13はループ状繊維束11を構成する糸よりも糸径を小さくすることができる。糸径が小さければ結び目12c、13cは、結節しやすく、小さくできる。また、折り返しのみによる処置を行う場合にあっては、折り返し部の飛び出を小さくでき出っ張りは小さくなる。
また、一般的に、走行姿勢を維持するための装置の一部は、織物の片方の側面にのみ配置されるが、織物の幅が適正でない場合は、その反対側の側面についても、製紙マシンのフレームに擦れる場合があるため、接合用芯線の端部の処置は、両側面について行うことが望ましい。
The joining core wire 10C inserted into the communication hole 50 is provided.
As shown in FIG. 7, the joining core wire 10C includes a loop-shaped fiber bundle 11 and auxiliary core wires 12 and 13 fixed to both ends of the loop-shaped fiber bundle 11. The configurations and effects of the loop-shaped fiber bundle 11 and the auxiliary core wires 12 and 13 are as described above.
The auxiliary core wires 12 and 13 have knots 12c and 13c formed in a bump shape on the ears 35 of the edges 3a and 4a of the woven fabric for endped papermaking 1a, and further have sewn portions 12d and 13d sewn into the woven fabric. .. By applying an adhesive to the sewn portions 12d and 13d, it can be fixed more firmly. When the auxiliary core wire is a spun yarn or a mixed yarn of a spun yarn and a monofilament, the adhesiveness is particularly good, so that the adhesive efficiency is particularly excellent.
The selvage portion 35 is notched inward of the edge portions 3a and 4a, and it is preferable that the knots 12c and 13c do not protrude from the width of the woven fabric 1A with the seam for papermaking.
Even when the number of joining core wires is large and the thread diameter is large, it is the auxiliary core wires 12 and 13 that protrude from the width of the papermaking seam-equipped woven fabric 1A, and the auxiliary core wires 12 and 13 have a loop shape. The yarn diameter can be made smaller than that of the yarn constituting the fiber bundle 11. If the thread diameter is small, the knots 12c and 13c are easy to knot and can be made small. Further, when the treatment is performed only by folding back, the protrusion of the folded-back portion can be reduced and the protrusion can be reduced.
Also, in general, a part of the device for maintaining the running posture is arranged only on one side of the woven fabric, but if the width of the woven fabric is not appropriate, the paper making machine is also placed on the other side. It is desirable to treat the ends of the joining core wire on both sides, as it may rub against the frame.

製紙用シーム付き織物1Bは、図6(b)に示すように、製紙用シーム付き織物1Aにおいて、ループ状繊維束(コイル状繊維束)17を使用している。他の構成は、製紙用シーム付き織物1Aと同様である。ループ状繊維束17は、15巻することにより30本の繊維束を構成している。実施形態に係る連通孔50は、第1経糸51と第4経糸54から形成されるため、その内径を大きくすることができる。そのため、このような本数の多い繊維束であっても接合用芯線として使用できる。 As shown in FIG. 6B, the woven fabric 1B with a seam for papermaking uses a loop-shaped fiber bundle (coil-shaped fiber bundle) 17 in the woven fabric 1A with a seam for papermaking. Other configurations are the same as those of the woven fabric 1A with a seam for papermaking. The loop-shaped fiber bundle 17 constitutes 30 fiber bundles by winding 15 times. Since the communication hole 50 according to the embodiment is formed from the first warp 51 and the fourth warp 54, the inner diameter thereof can be increased. Therefore, even such a large number of fiber bundles can be used as a core wire for joining.

製紙用シーム付き織物2は、図8に示すように、補助芯線12、13が、有端状製紙用織物1aの縁部4aの耳部35に瘤状に結び目12c、13cを形成し、更に耳部35に引き込んだ引き込み部12e、13eを有する(図6(c)参照。)。縁部3a、4a付近の織物に引き込んでもよいが、引き込み部12e、13eのように、連通孔50の外部の内孔30h又は40h内に引き込むことが好ましい。こうすることで、連通孔50の外面と内孔30h又は40hの内面とで、引き込み部12e、13eを確実に固定することができる。更に引き込み部に接着剤を塗布することが好ましい点、耳部35が切込み形成されている点については、製紙用シーム付き織物1Aと同様であり、前述の通りである。 In the paper-making seam-attached woven fabric 2, as shown in FIG. 8, the auxiliary core wires 12 and 13 form knots 12c and 13c in a bump shape on the selvage portion 35 of the edge 4a of the end-shaped paper-making woven fabric 1a, and further. It has retractable portions 12e and 13e retracted into the ear portion 35 (see FIG. 6C). It may be pulled into the woven fabric near the edges 3a and 4a, but it is preferably pulled into the inner hole 30h or 40h outside the communication hole 50 as in the pulling portions 12e and 13e. By doing so, the lead-in portions 12e and 13e can be reliably fixed between the outer surface of the communication hole 50 and the inner surface of the inner hole 30h or 40h. Further, it is preferable to apply an adhesive to the pull-in portion, and the ear portion 35 is notched and formed, which is the same as that of the woven fabric 1A with a seam for papermaking, as described above.

It can be an endless seam felt for papermaking.

[5]リードワイヤー
前記「リードワイヤー」は、前記接合用具を構成し、接合用芯線を連通孔内に誘導するための部材である。
具体的には、図5(a)に示すように、リードワイヤー20は、接合用芯線10Aを構成するループ状繊維束11の他端11bに取り付けて、接合用芯線10Aを上記連通孔50内に誘導する部材である。
リードワイヤー20は、1本の長尺の線材を中間部から二つ折りに曲げ形成されており、ループ状繊維束11を掛け止めするフック部20aと、一対の近接対向した線片から形成されており、連通孔50内に誘導する先端部20bに向かって直線的に延びている。
[5] Lead wire The "lead wire" is a member that constitutes the joining tool and guides the joining core wire into the communication hole.
Specifically, as shown in FIG. 5A, the lead wire 20 is attached to the other end 11b of the loop-shaped fiber bundle 11 constituting the joining core wire 10A, and the joining core wire 10A is placed in the communication hole 50. It is a member that guides to.
The lead wire 20 is formed by bending one long wire rod in half from the intermediate portion, and is formed of a hook portion 20a for hooking the loop-shaped fiber bundle 11 and a pair of closely opposed wire pieces. The wire extends linearly toward the tip portion 20b that guides the communication hole 50 into the communication hole 50.

リードワイヤー20は、有端状製紙用織物1aの幅方向に形成された連通孔50を挿通してループ状繊維束11を引き出す必要があるため、幅方向長さよりも長く設定されている。
リードワイヤー20の材質は特に限定はないが、軟質の金属線であることが好ましい。軟質であれば、ループ状繊維束11を傷つくのを防ぐことができる。また、同様の理由から断面は円形であることが好ましい。線径は特に限定はないが、0.3〜1.0mmであることが好ましく0.4〜0.8mmであることが更に好ましい。0.3mm未満では、ループ状繊維束11を傷つけるおそれがあり、1.0mmを超えると連通孔50に挿通しがたくなる。
The lead wire 20 is set longer than the length in the width direction because it is necessary to insert the communication hole 50 formed in the width direction of the woven fabric 1a for endped papermaking to pull out the loop-shaped fiber bundle 11.
The material of the lead wire 20 is not particularly limited, but is preferably a soft metal wire. If it is soft, it can prevent the loop-shaped fiber bundle 11 from being damaged. Further, for the same reason, it is preferable that the cross section is circular. The wire diameter is not particularly limited, but is preferably 0.3 to 1.0 mm, and more preferably 0.4 to 0.8 mm. If it is less than 0.3 mm, the loop-shaped fiber bundle 11 may be damaged, and if it exceeds 1.0 mm, it becomes difficult to insert it into the communication hole 50.

また、フック部20aの形状もループ状繊維束11を掛け止めできれば特に限定はなく、V字状、U字状、コの字状その他の形状とすることができる。
リードワイヤー20は、2本の線材を溶接等により接続して、フック部20aを形成することもできる。この場合、最初に、連通孔50に2本の線材を挿入し、その後端部分が連通孔の一端50aから露出した状態にする。この場合、連通孔50に1本ずつ挿通しても、2本束にして同時に挿通してもよい。次いで、ループ状繊維束の他端11bを2本線材で挟持してから、溶接によってフック部20aを形成する。
しかしながら、リードワイヤー20は、一本の線材を二つに折り曲げ形成することが好ましい。すなわち、織物の幅の2倍よりも長い線材を長さの中心で折畳んだものをリードワイヤーにする、折畳んだ部分すなわちフック部20aにループ状繊維束の他端側11bを引っ掛けて、見かけ上2本の線材をループに挿通する。
このような線材を折畳んだ構造には、引き込む時にループ状繊維束の他端側11bの掛け止め付近に熔接部がないので挿通に際して強い力で引っ張られても破壊の危険がない。
更に、図5(b)に示すように、フック部20aにループ状繊維束11を掛け止めした後、先端部20bを溶接して溶接部20wを形成して連通孔50に挿通してもよい。こうすることで、接合用ループへの挿通が引っ掛かりなく行われ、スムーズになる。接合用芯線の引き込みが終了したら先端の溶接を切断して線材をループ状繊維束から外す
また、リードワイヤーは等分に二つ折りにしている必要はなく一方の線片が他方の線片より長くてもよい。例えば、図5(c)に示すリードワイヤー22のように、他方の線片を短くしたフック部22aを形成し、先端部22bは一本の線片からなるものでもよい。
フック部22aにループ状繊維束11を掛け止めした後、フック部先端を溶接して溶接部22wを形成して連通孔50に挿通してもよい。接合用芯線の引き込みが終了したら溶接部22wを切断して線材をループ状繊維束から外す。
以上の構成をしたリードワイヤーは、簡易な構成でありながら、ループ状繊維束を円滑に連通孔50内に挿入することができ、効率的に有端状製紙用織物1aを接合して、無端状織物を形成する上で、極めて有効な部材である。
Further, the shape of the hook portion 20a is not particularly limited as long as the loop-shaped fiber bundle 11 can be hooked, and can be V-shaped, U-shaped, U-shaped or other shapes.
The lead wire 20 can also form a hook portion 20a by connecting two wires by welding or the like. In this case, first, two wires are inserted into the communication hole 50 so that the rear end portion is exposed from one end 50a of the communication hole. In this case, the communication holes 50 may be inserted one by one, or two bundles may be inserted at the same time. Next, the other end 11b of the loop-shaped fiber bundle is sandwiched between two wires, and then the hook portion 20a is formed by welding.
However, the lead wire 20 is preferably formed by bending one wire in two. That is, a wire rod longer than twice the width of the woven fabric is folded at the center of the length to form a lead wire, and the other end side 11b of the loop-shaped fiber bundle is hooked on the folded portion, that is, the hook portion 20a. Apparently two wires are inserted into the loop.
In such a structure in which the wire rod is folded, there is no welded portion in the vicinity of the hooking portion on the other end side 11b of the loop-shaped fiber bundle when it is pulled in, so that there is no danger of breakage even if it is pulled by a strong force at the time of insertion.
Further, as shown in FIG. 5B, after the loop-shaped fiber bundle 11 is hooked on the hook portion 20a, the tip portion 20b may be welded to form the welded portion 20w and inserted into the communication hole 50. .. By doing so, the insertion into the joining loop is performed without being caught and becomes smooth. When the lead wire for joining is completed, the weld at the tip is cut to remove the wire from the looped fiber bundle. Also, the lead wire does not need to be folded in half and one wire piece is longer than the other wire piece. You may. For example, as in the lead wire 22 shown in FIG. 5C, the hook portion 22a in which the other wire piece is shortened may be formed, and the tip portion 22b may be composed of one wire piece.
After hooking the loop-shaped fiber bundle 11 on the hook portion 22a, the tip of the hook portion may be welded to form the welded portion 22w and inserted into the communication hole 50. When the lead-in of the core wire for joining is completed, the welded portion 22w is cut to remove the wire rod from the loop-shaped fiber bundle.
Although the lead wire having the above structure has a simple structure, the loop-shaped fiber bundle can be smoothly inserted into the communication hole 50, and the end-shaped papermaking woven fabric 1a is efficiently joined to endlessly. It is an extremely effective member for forming a shaped woven fabric.
