本考案は製紙用ドライヤーフェルトの接合部に関し、該
フェルトの表面平滑性、弾力性を損なうことのない接合
部にあって、すぐれた耐久性を併せ持った接合部を提供
するものである。[Detailed description of the invention] The present invention relates to the joints of dryer felt for paper manufacturing, and provides a joint that does not impair the surface smoothness and elasticity of the felt and has excellent durability. It is something to do.
通常、製紙用ドライヤーカンバスは湿紙を乾燥させるた
めに多くの加熱シリンダーに湿紙を圧接させながら、多
数のカンバスロールと該加熱シリンダーの間を纒回し無
端走行している。Normally, a dryer canvas for papermaking runs endlessly between a number of canvas rolls and the heating cylinders while pressing the wet paper against a number of heating cylinders in order to dry the paper.
そして、一般にはドライヤーカンバスは、湿紙より広幅
にして、湿紙を全面的に均等に圧接している。Generally, the dryer canvas is wider than the wet paper, and the wet paper is pressed evenly over the entire surface.
それであるから、ドライヤーカンバスの両耳部及びその
内側の若干幅間は、湿紙をかいせず直接加熱シリンダー
に接し、他の部分に較べて劣化がはなはだしかった。Therefore, both ears of the dryer canvas and a slight width inside thereof were in direct contact with the heating cylinder without using wet paper, and the deterioration was more severe than in other parts.
又、ドライヤーカンバスは製紙機ロールの平行度の狂い
等で蛇行したり、ガイド装置の故障等で片寄り走行する
ことがあり、耳部が損傷したり過度の負荷が力)かるこ
とが多かった。In addition, the dryer canvas sometimes meandered due to the paper machine roll being out of parallel, or ran lopsided due to a failure of the guide device, which often resulted in damage to the ears or excessive load. .
しかもこのような現象は光熱カンバス接合部にも発生す
るから、特に牽引力の加わる接合部では損傷がその耳部
から幅中央部に波及し、補修不可能となるか又は補修で
きるにしても多くの時間と労力を要していた。Moreover, this phenomenon also occurs at photothermal canvas joints, so especially at joints where traction is applied, damage spreads from the edges to the center of the width, making it impossible to repair or, even if it can be repaired, much of the damage It took time and effort.
このため従来から、接合耳部を補強するために接合耳部
に補強用紐を取り付け、ドライヤーカンバスの両端接合
後、その紐を結び合す方法(実公昭47−41925号
)や、耳部の接合用ループに中央部より強度や耐久性の
すぐれたループを用いていた。For this reason, conventional methods have been used, such as attaching reinforcing strings to the joint ears and tying the strings together after joining both ends of the dryer canvas (Utility Model Publication No. 47-41925). The joining loop used was a loop that was stronger and more durable than the central part.
一方、近年製紙用ドライヤーカンバスとして基布の片面
又は両面にウェブをニードルパンチングにより積層重合
したニードルフェルトが用いラレるようになって来た。On the other hand, in recent years, needle felt, in which a web is laminated and polymerized by needle punching on one or both sides of a base fabric, has been used as a dryer canvas for papermaking.
これは従来の織物のドライヤーカンバスでは得られない
表面平滑性及び弾力性が得られるためで特に上質紙用ド
ライヤーカンバスとして使用されて来た。This has been used particularly as a dryer canvas for high-quality paper because it provides surface smoothness and elasticity that cannot be obtained with conventional woven dryer canvases.
そうであるから、ニードリングによる製紙用ドライヤー
カンバス(以下製紙用ドライヤーフェルトと言う)の接
合部も極力本体と同様の厚さ、同等の表面性が求められ
ている。Therefore, the joints of papermaking dryer canvas (hereinafter referred to as papermaking dryer felt) by needling are required to have the same thickness and surface properties as the main body.
ために前述の接合耳部の取付紐による補強では、紐及び
その紐の結び目が接合部表面より突出することになり、
製紙機をC回走行中に突出部の接圧が高くなり摩耗によ
る損傷が顕著であった。Therefore, when reinforcing the joint ears with the attachment string described above, the string and the knot of the string protrude from the surface of the joint,
While the paper was run C times through the paper making machine, the contact pressure on the protrusion increased and damage due to wear was significant.
又、突出部をおおうカバー布や突出部と同等の厚さの添
付布により突出部を保護する場合、布を取り付けた部分
の厚さを増すことになり、ロール等を転回する時、縁部
又はその箇所の本体接合部に過度の負荷がかかり、接合
部の損傷を早めることになる。In addition, when protecting the protruding part with a cover cloth that covers the protruding part or an attached cloth with the same thickness as the protruding part, the thickness of the part where the cloth is attached increases, and when the roll etc. is turned, the edge Otherwise, an excessive load will be applied to the joint of the main body at that point, leading to premature damage to the joint.
又一方、接合耳部の接合用ループに強力や耐久性にすぐ
れたループを用いるにしても、本体と別のループ材料を
用意したり、別の取付は方法を用いたりしなくてはなら
ず煩雑であり、手間を必要とした。On the other hand, even if a strong and durable loop is used for the joining loop at the joining ear, it is necessary to prepare a different loop material from the main body or use a different attachment method. It was complicated and required time and effort.
本考案は前記の欠点を改良したものであって、その構成
を実施例にもとづき以下説明する。The present invention improves the above-mentioned drawbacks, and its configuration will be explained below based on embodiments.
図面において1は本体基布である。In the drawings, 1 is the main body base fabric.
2は接紙面側ウェブ及び3は裏面側ウェブである。2 is a web on the contact side and 3 is a web on the back side.
4は金属フック(第2図に示しである)等の接合ループ
であり5は接合用芯線である。4 is a joining loop such as a metal hook (shown in FIG. 2), and 5 is a joining core wire.
ウェブ2,3はいずれも本体基布1にニードルパンチン
グにより重合固着しである。The webs 2 and 3 are both polymerized and fixed to the main body base fabric 1 by needle punching.
接合ループ4は本体基布1より接紙面側ウェブ2を、ド
ライヤーフェルトの両端部において一時的に基布との結
合を切り、従来の方法によりループ又は金属フックを接
合部全幅にわたり取り付けである。The joining loop 4 is formed by temporarily cutting the bond between the web 2 on the side facing the paper side of the main body base fabric 1 and the base fabric at both ends of the dryer felt, and attaching a loop or a metal hook over the entire width of the joint by a conventional method.
しかる後、ウェブ2は再び本体基布に従来の方法で固着
しである。Thereafter, the web 2 is again fixed to the base fabric in a conventional manner.
尚、本体基布1より端部から延長したタテ糸でループを
形威した後再び本体基布に綴り込んだり、隣接のタテ糸
を取り除いた跡に挿入する方法や、接合用のう線状線状
体を継合した後、本体基布に綴り込んだり挿入する方法
も採用できる。In addition, there are methods such as forming a loop with a warp thread extending from the end of the main body base fabric 1 and then re-tapping it into the main body base fabric, inserting it into the area where the adjacent warp thread has been removed, or forming a loop with a warp thread for joining. It is also possible to adopt a method of binding or inserting the linear bodies into the base fabric of the main body after joining them.
又、ウェブをニードルパンチングする前の基布の時にル
ープを形成しウェブをニードルパンチングする場合も含
まれる。It also includes a case where loops are formed in the base fabric before the web is needle-punched and the web is needle-punched.
このように接合ループを取り付けた後、接紙面側ウェブ
を接合部の耳部において適当長さ幅にわたって取り除く
。After the joining loop has been attached in this manner, the abutting side web is removed over an appropriate length and width at the ear of the joining portion.
好ましくは、湿紙幅にかからない程度の大きさとする。Preferably, the size is such that it does not cover the width of the wet paper.
6は耳部補強用ニードルフェルト片である。6 is a needle felt piece for reinforcing the ears.
耳部補強用ニードルフェルト片6は本体と同様の技術で
作成されているが、該ニードルフェルト片6は取り除い
た接紙面側ウェブ2の厚さとほぼ同等であることが望ま
しいので本実施例の場合ウェブは基布の片面にのみ重合
積層されている。The needle felt piece 6 for reinforcing the ear part is made using the same technique as the main body, but it is desirable that the needle felt piece 6 has a thickness almost equal to the thickness of the paper-contact side web 2 that has been removed, so in this example The web is polymerized to only one side of the base fabric.
該ニードルフェルト片6は前もってその端部の一方のウ
ェブとヨコ糸を取り除いて延長タテ糸7を形威し該補強
フェルト片6は切り欠いたウェブ2と同じ大きさ、形状
に仕上げられて、切り欠き部に重合されミシンによる縫
着や接着等の従来の方法によって装着されている。One of the webs and weft threads at the end of the needle felt piece 6 is removed in advance to form an extended warp thread 7, and the reinforcing felt piece 6 is finished in the same size and shape as the cut-out web 2. It is superimposed on the notch and attached by conventional methods such as sewing with a sewing machine or gluing.
尚、補強フェルト片6はウェブを積層重合してあり、厚
みがあるので後述のタテ糸同志の結び目が接紙上面に出
にくいので通常ニードルフェルトが用いられるが、ウェ
ブがない織物を使用することもできる。Note that the reinforcing felt piece 6 is made by laminating and polymerizing webs, and is thick, so that the knots between the warp threads, which will be described later, are difficult to come out on the top surface of the paper, so needle felt is normally used, but a woven fabric without webs can be used. You can also do it.
このように両端部を仕上げられた製紙用ドライヤーフェ
ルトは製紙機に掛は入れられた後、接合しループ4を噛
み合せて共通孔に芯線5を挿入して接合される、しかる
後、切り欠き部に装着した耳部補強用ニードルフェルト
片6の延長タテ糸7を1本又は複数本づつ収束した対向
しているもう一方の端部延長タテ糸7′と結束する。The papermaking dryer felt with both ends finished in this way is put into the papermaking machine, and then joined together by engaging the loops 4 and inserting the core wire 5 into the common hole. The extended warp threads 7 of the needle felt piece 6 for reinforcing the ears attached to the selvage section are tied together one or more lengths at a time with the opposite end extended warp threads 7'.
結束に際しては接合ループ4にかかるのと同程度の張力
でしかも各結び目が均一な張力になるようにする。When tying, the tension is the same as that applied to the joining loop 4, and each knot is made to have a uniform tension.
尚延長タテ糸7の収束本数はその結び目の大きさが接合
部の接紙面上に突出しない程度に適宜選ばれる。The number of converging extended warp threads 7 is appropriately selected so that the size of the knot does not protrude above the contact surface of the joint.
又、補強部の必要強度によっては延長タテ糸は間引いて
おくことも出来る。Further, depending on the required strength of the reinforcing portion, the extended warp threads may be thinned out.
そして、必要に応じて結び目には接着剤等の樹脂が結び
目はつれ防止のために塗布される。Then, if necessary, a resin such as an adhesive is applied to the knot to prevent it from becoming tangled.
又、結び目糸端も適当な長さに切断される。The end of the knotted thread is also cut to an appropriate length.
このように接合耳部の補強にニードルフェルトのタテ糸
を用いることが出来るので、補強に必要な強度は十分に
得られる。As described above, since the warp threads of needle felt can be used to reinforce the joining ears, sufficient strength required for reinforcement can be obtained.
又、その延長されたタテ糸は接紙面の内側にあり、そし
て、延長タテ糸の結び目の大きさも適宜選べるので結び
目は接合部の接紙面より突出することがないので過度の
接圧を受けることがなく又、摩耗して損傷することもな
い。In addition, the extended warp thread is inside the paper contact surface, and the size of the knot of the extended warp thread can be selected as appropriate, so the knot will not protrude beyond the paper contact surface of the joint, so it will not be subjected to excessive contact pressure. There is no risk of wear and damage.
接紙面側のウェブに換えて、それと同等の厚みの補強用
ニードルフェルトを装着して接合耳部補強に用いるので
接合耳部の厚さはドライヤーフェルト本体の厚さとほぼ
同じに作成できるので、耳部接合ループに過度の負荷が
かかることもなく長期の使用に耐える。Instead of the web on the contact side, a reinforcing needle felt with the same thickness is attached and used to reinforce the joint selvage, so the thickness of the joint selvage can be made to be almost the same as the thickness of the dryer felt body, so the selvage It can withstand long-term use without excessive load being applied to the joint loop.
しかも接合耳部のウェブを切り欠いた跡に補強用ニード
ルフェルト片を装着しその延長タテ糸を収束し結束する
だけであるので作成が容易である。In addition, it is easy to manufacture because all that is required is to attach a piece of reinforcing needle felt to the cutout of the web of the joint selvedge, and then converge and tie the extended warp threads.
以上、上質紙用ドライヤーフェルトの接合部のように本
体と同等の厚さ、表面性を要求される接合部であって、
すぐれた耐久性を持ち作成の容易な接合部となる。As mentioned above, the joints require the same thickness and surface properties as the main body, such as the joints of dryer felt for high-quality paper.
It has excellent durability and is an easy-to-make joint.
