少なくするようにしたコンペアベルトは周知である。[Detailed Description of the Invention] A fine mesh-like unevenness is formed on the belt surface to increase the friction between the belt and the carried object, increasing the anti-slip effect, and the cushioning properties of the unevenness make it easier to handle when loading. Compare belts are well known that absorb and reduce shock and reduce the transmission of belt vibrations to cargo during transport.

。This compare belt is called a rough top conveyor belt, and its surface unevenness is functionally as high as possible, and the height of the protrusions is uniform in order to obtain the same characteristics on any part of the surface and increase the product value. It is hoped that there will be.

プベルトを製造する布に関するものである。In the present invention, a woven fabric (fabric fabric) is layered on the surface of an unvulcanized rubber belt and vulcanized under pressure, and then the woven fabric is peeled off from the belt surface to form an uneven pattern of the woven fabric on the surface of the rubber belt. It relates to fabrics for manufacturing.

多数のからめ糸３とからなっている。As shown in Figures 1 to 3, this cloth has a large number of warp threads 1 arranged in parallel on the same plane at the same intervals, and warp threads 1
A large number of weft threads 2 are alternately located on the front and back sides of the machine and are arranged in parallel in contact with the warp threads 1 at the same intervals and perpendicular to the warp threads 1, and warp threads inserted between adjacent warp threads 1 and sequentially and alternately surrounding the front and back weft threads 2. 1 and a large number of lace yarns 3 arranged in support of adjacent weft yarns 2.

糸２、たて糸１、からめ糸３として用いていた。Conventionally, when weaving this kind of cloth, if we use twisted threads of the same material and the same thickness during weaving, there will be less loss and we will be able to make it at a lower cost. It was used as warp yarn 1 and leash yarn 3.

又繰り返し受けるプレス圧やプレス熱に対して、製織し
た布の厚みが変化してはいけないので、熱処理を施した
熱安定性の良い剛性の非常に高い糸が用いられていた。Furthermore, since the thickness of the woven cloth should not change due to repeated press pressure and press heat, heat-treated threads with good thermal stability and extremely high rigidity were used.

らないという欠点が生じた。For this reason, when woven into cloth, there is no problem if the threads are thin, but if the threads are made thicker to form a pattern with large convex parts, the threads are stiff and do not blend into each other during weaving. When the fabric and unvulcanized rubber belt are layered and heated and pressurized, a part of the rubber will ooze out on the back side, and when the fabric is peeled off from the surface of the rubber belt, some of the rubber will ooze out. Some of the protrusions that were hanging down were torn off, resulting in uneven patterns on the surface of the protrusions, resulting in uneven functionality, and the product had only a small commercial value. Furthermore, if a part of the pattern of the convex portions is torn off and remains on the cloth, there is a problem in that the convex portions will be formed during repeated use (especially when both sides are used) and must be removed.

It is intended to offer cloth.

見出したものである。In order to achieve the above object, the present invention breaks the conventional concept that the warp, weft, and leash threads used for cloth should be made of the same material and have the same thickness, and it resists the pressure applied during vulcanization. For the Karame yarn, use a yarn with high bending rigidity per yarn as in the secondary warp, and deform either or both of the warp and weft yarns under the press pressure (approximately 5 to 15 k9/ground) during press molding. Possible bending rigidity per thread is 3
By using less than half the thread size, even if there is a gap between the threads during weaving, when forming the raft belt, either the warp or the weft will deform due to the rubber pressure, closing the gap and creating a fabric. It has been discovered that it is possible to use a cloth that can reliably form a high and uniform uneven pattern on the surface of a rubber belt without causing any rubber seepage on the back side of the rubber belt.

使用する繊維は、従来と同様に合成繊維や半合成繊維で
熱安定性の良いものであればよく、糸を撚った時例えば
ポリエステル繊維の場合においては約２２０午０で数分
間加熱処理（ヒートセット）したものを使用する。The fibers used may be synthetic fibers or semi-synthetic fibers as long as they have good thermal stability, as in the past, and when the yarn is twisted, for example, in the case of polyester fibers, it is heated at about 220:00 for several minutes ( heat set).

またゴムなどが布に付着しないように、糸または布にシ

ものが必要でよこ糸、−たて糸のみは２．仇舷以上でも
以下であってもかまわない。The thickness of the thread varies depending on the uneven pattern formed on the surface of the rubber belt, but according to the inventor's test results, if the protrusions are on the 4th side or less, the frictional resistance is small and the cushioning properties are poor. The above is desirable, and the thickness of the thread used for the cloth corresponds to the height of this convex part. If you need more than the bow, weft and warp only 2. It doesn't matter if it's above or below the ship's side.

らめ糸の３分の２以下と低い方がよい。In addition, the bending rigidity of each thread is JISLI079 (1976) 6 because it can withstand the press pressure that the cloth is repeatedly subjected to.
In the bending rigidity test using the 231A method (Gurley method), the bending rigidity of one leash yarn is better, and the warp and weft yarns are low at two-thirds or less of the leash yarn for either or both of the leash yarns. It's better.

み目を塞ぐためである。The reason for this is the pattern forming press pressure (5 to 15k9/ground)
In this case, the leash yarn does not deform at all, but the warp and weft yarns deform to a certain extent compared to the leash yarn, and this is to close the stitches that occur between the threads of the cloth.

ある。To measure the bending rigidity of one yarn, for example, eight yarns of 1100 denier multifilament polyester fibers that have been subjected to a known heat treatment are placed in two strands (10
Gama) Three twisted threads are further twisted in the Z direction to create a thickness of approximately 2. The bending stiffness of each leash thread used in the current cloth for the bow is 3.4 mm according to the test method described above.

The thickness of the yarn obtained by reducing the number of twists in the Z direction from 15 twists to 7 twists was approximately 2.3 Yanagi, and the bending rigidity of each yarn was 1.2 Yanagi. Next, the fabric according to the present invention and the results of performance tests thereof will be shown in comparison with conventional products.

The cuts were noticeable and the protrusions 4 were not aligned. Also, the cloth after 100 uses is 8.1

K9' staff, the maximum is 15k9/status,
If the pressure at which the rubber oozes out reaches 20k9', it is unlikely that the rubber will ooze out from one side of the fabric to the pond side during molding.

りがないことを示している。However, if the bending rigidity of each leash yarn is made soft, such as 3.4 ta or less, it will gradually be compressed and its thickness will decrease during use. As the thickness decreases, the difference in height between the unevenness on the surface of the molded rubber belt also decreases, reducing the product value. Examples 1 and 2, along with Examples 3 and 4, show that the amount of decrease in thickness due to use is extremely small, and the durability is almost the same as that of conventional products.

In this case, the oozing pressure of the rubber reaches 30k9',
In practical terms, it is possible to completely prevent rubber oozing and to obtain a fabric with good mold release properties.
