Field of the Invention The present invention relates to a papermaking dryer in which a weft yarn is resin-processed before weaving, a joint portion of a canvas, and a method for forming the joint portion, and a papermaking dryer using a woven fabric using the joint portion as a base fabric. (Needle) Concerning canvas.

Description of the Related Art In order to prepare a joint portion of a dryer canvas for papermaking, first, the weft yarns at both ends of the woven canvas are removed over a predetermined length to form a comb-shaped warp yarn. Next, the interdigital warp is folded back to form a joining loop. The weft is stitched into the finally removed weft portion.

利点がある。For the weft thread to be stitched in, there is an actual construction of Shokai 62-16.
Generally, the removed weft yarn itself is used as described in 2298. Since this weft has already been crimped by heat setting, when weaving the warp, the same woven structure as the part (canvas body) other than the joint end can be created, and the thickness of the joint end is almost the same as the canvas body. There is an advantage of being equal.

般に行われている。Depending on the use of the papermaking dryer canvas, a high level of soft and smooth surface property is required. For such applications, a dryer canvas in which a monofilament yarn is used as a warp and a flexible yarn obtained by twisting a spun yarn on at least one layer of a weft is used. In this case, in order to compensate for the lack of rigidity and the reduction in dimensional stability associated with the use of spun yarn, it is common practice to subject the entire canvas fabric to resin treatment.

行われている。This resin processing is also carried out in a papermaking dryer canvas using monofilament yarn having a flat cross section. As disclosed in Japanese Patent Publication No. 58-28398, a monofilament yarn having a flat cross section has recently been used for improving the surface smoothness of a dryer canvas for papermaking, but it is softer. In applications where surface properties are required, as in the above, at least one layer of wefts is spun yarn, and,
In order to compensate for the lack of rigidity and the reduction in dimensional stability associated with the use of spun yarn, it is common practice to subject the entire canvas fabric to resin treatment.

る場合があった。[0006] The joint portion of the dryer canvas for papermaking using a monofilament yarn having a flat cross section as the warp is formed by the same method as described above, but because of the use of the monofilament yarn having a flat cross section, the joint surface side (PS ) And the machine side (BS) are asymmetrical, it is necessary to twist the warp by 180 ° to form the joining loop. This is for facilitating the binding of the warp threads. 18 warp
When twisted at 0 °, the portion of the twisted portion of the flat yarn which is vertically long in cross section pushes the front weft on the paper contact surface side (PS) toward the paper contact surface side (PS). For this reason, the joining loop swells and projects to the paper contact surface side (PS), and the surface smoothness of the joint portion cannot be obtained. As a result, a paper mark may be generated on a paper such as a high-quality paper or a thin paper that requires a delicate paper surface.

できない。又継手部が摩損し、寿命が短くなる。Recently, the speed of paper machines such as single-run canvas method and berlan method (trademark of Beloit Company in the United States) has been further developed. Is required to have a stricter surface smoothness than ever before. When the twisting of the joining loop is provided on the paper-contacting surface side, the influence of the twisting unavoidably appears on the paper-contacting surface side and the surface smoothness is impaired, so that it is not possible to sufficiently cope with the speedup of the paper machine. In addition, the joint part will be worn away and the life will be shortened.

が接紙面側（ＰＳ）に出ない。As shown in FIG. 9, the twisted portion 5 of the joining loop 4 is formed.
Is provided on the opposite machine surface side (BS) instead of on the paper contact surface side (PS) (refer to the Official Technical Report No. 92-15467 published by the Institute of Invention and Innovation July 1, 1992). No effect on PS side.

このため前記実開昭６２−１６２２９８号記載の方法は
そのままでは使用できない。In applications where smooth surface properties are required as described above, soft and smooth surface properties equivalent to the canvas body are also required in the joint portion. But,
When weft yarn made of the same spun yarn as the main body is used,
The crimp is blurred. Further, since the spun yarn lacks rigidity, the twist of the yarn is likely to return, and it is difficult to bind because the yarn may come apart during the binding and get caught on the warp.
Therefore, the method described in Japanese Utility Model Publication No. 62-162298 cannot be used as it is.

は同じである。図９のように接合用ループの捩れを機械
面側に設けても、緯糸にスパン糸を撚った糸を使用する
限り、緯糸の綴り込みの困難性の問題は依然として残
る。The same applies to the joint portion of a dryer canvas for papermaking, which uses a monofilament yarn having a flat cross section as a warp. Even if the twisting of the joining loop is provided on the machine surface side as shown in FIG. 9, as long as a yarn obtained by twisting a spun yarn is used as the weft, the problem of difficulty in binding the weft still remains.

も、緯糸と経糸の交絡点では樹脂の被覆が不完全になる
ことが避けがたく、スパン糸の緯糸の耐久性に課題を生
じていた。Further, even if the entire woven fabric is resin-processed after weaving, it is unavoidable that the coating of the resin is incomplete at the entanglement point of the weft yarn and the warp yarn, which causes a problem in the durability of the weft yarn of the spun yarn. .

It is characterized in that it is a spun yarn twisted with resin.

You can make it thinner.
