Description

本発明は、コンベヤベルトを接合または補修する際に用いられる、コンベヤベルト補強用帆布に関するものである。   The present invention relates to a canvas for reinforcing a conveyor belt, which is used when joining or repairing a conveyor belt.

ベルトを構成するゴム材の中に補強帆布が配置されたコンベヤベルトが破損した場合に備え、上記補強帆布と同じ補修用の補強帆布を常時在庫しておくことが必要とされている。
図４（ａ），（ｂ）は、上下のカバーゴム５０ａ，５０ｂの間に、帆布５０ｐの両面にトリートゴム５０ｑ，５０ｒを被着して成る補強用帆布５０Ｋが介挿されたコンベヤベルト５０を補修する例を示す図である。コンベヤベルト５０の補修に際しては、まず、コンベヤベルト５０の破損した部分５０Ｘの両端部５０Ａ，５０Ｂを切り取った後、この両端部５０Ａ，５０Ｂの間に補修用の補強帆布５１を配置するとともに、この補修用の補強帆布５１と充填用のカバーゴム５０ｃ，５０ｄとを接着して、上記コンベヤベルト５０の両端部５０Ａ，５０Ｂを接合してループ状にする方法が一般的である。
上記補修用の補強帆布５１は、ナイロン、ポリエステル、ビニロン、アラミド等の有機繊維から成る補強帆布本体５２の表面５２ａ側と裏面５２ｂ側とにそれぞれトリートゴム５３ａ，５３ｂが被覆されたもので、上記トリートゴム５３ａ，５３ｂが未加硫ゴムの場合には、上記トリートゴム５３ａ，５３ｂと上記充填用のカバーゴム５０ｃ，５０ｄとを加硫接着することにより、上記コンベヤベルト５０の両端部５０Ａ，５０Ｂを接合する（例えば、特許文献１参照）。
上記補修用の補強帆布５１は、通常、リールなどに巻取って保存されるが、未加硫状態のゴムは長期保存が難しいので、上記補修用の補強帆布５１を予め加硫処理しておき、上記トリートゴム５３ａ，５３ｂと上記充填用のカバーゴム５０ｃ，５０ｄの接着時には、上記トリートゴム５３ａ，５３ｂと上記充填用のカバーゴム５０ｃ，５０ｄとの間にそれぞれ未加硫ゴムのシート５４ａ，５４ｂを挿入して加硫接着する方法が行われている。このとき、上記トリートゴム５３ａ，５３ｂの表面をバフ研磨し、その表面に微細な凹凸を設けることにより、上記トリートゴム５３ａ，５３ｂと上記充填用のカバーゴム５０ｃ，５２ｄとの接着性を高めるようにしている。
実開平５−１９２２４号公報 In case the conveyor belt in which the reinforcing canvas is disposed in the rubber material constituting the belt is damaged, it is necessary to always stock the same reinforcing canvas for repair as the reinforcing canvas.
4 (a) and 4 (b) show a conveyor belt 50 in which reinforcing canvas 50K formed by attaching treat rubbers 50q and 50r on both sides of a canvas 50p between upper and lower cover rubbers 50a and 50b. It is a figure which shows the example which repairs. When repairing the conveyor belt 50, first, after cutting off both end portions 50A and 50B of the damaged portion 50X of the conveyor belt 50, a reinforcing canvas 51 for repair is disposed between the both end portions 50A and 50B. A method is generally employed in which the reinforcing canvas 51 for repair and the cover rubbers 50c and 50d for filling are bonded, and both end portions 50A and 50B of the conveyor belt 50 are joined to form a loop.
The reinforcing canvas 51 for repair is obtained by coating treat rubbers 53a and 53b on the front surface 52a side and the back surface 52b side of a reinforcing canvas body 52 made of organic fibers such as nylon, polyester, vinylon, and aramid, respectively. When the treat rubbers 53a and 53b are unvulcanized rubbers, the treat rubbers 53a and 53b and the cover rubbers 50c and 50d for filling are vulcanized and bonded to each other so that both end portions 50A and 50B of the conveyor belt 50 are cured. Are joined together (see, for example, Patent Document 1).
The repair canvas 51 for repair is usually wound and stored on a reel or the like. However, since the unvulcanized rubber is difficult to store for a long time, the repair canvas 51 for repair is vulcanized in advance. When the treat rubbers 53a and 53b and the filling cover rubbers 50c and 50d are bonded, the unvulcanized rubber sheets 54a and 54d are disposed between the treat rubbers 53a and 53b and the filling cover rubbers 50c and 50d, respectively. 54b is inserted and vulcanized and bonded. At this time, the surface of the treat rubber 53a, 53b is buffed and fine irregularities are provided on the surface, thereby improving the adhesion between the treat rubber 53a, 53b and the filling cover rubbers 50c, 52d. I have to.
Japanese Utility Model Publication No. 5-19224

しかしながら、上記加硫処理された補修用の補強帆布５１は、長期保存には適しているものの、上記トリートゴム５３ａ，５３ｂの厚みが薄いことから、バフ研磨時に下層の補強帆布本体５２に傷を付け易いだけでなく、研磨後のトリートゴム５３ａ，５３ｂの表面にバフ粉などの異物が付着してしまい接着性が悪化するといった問題点があった。   However, although the reinforced vulcanized canvas 51 for repair is suitable for long-term storage, the thickness of the treat rubbers 53a and 53b is small, so that the lower reinforced canvas body 52 is damaged during buffing. Not only is it easy to attach, but there is a problem that foreign matter such as buff powder adheres to the surfaces of the treated treat rubbers 53a and 53b, resulting in deterioration of adhesiveness.

本発明は、従来の問題点に鑑みてなされたもので、長期保存ができて、なおかつ、トリートゴムとカバーゴムとを容易に接着することのできるコンベヤベルト補強用帆布を提供することを目的とする。   The present invention has been made in view of conventional problems, and an object thereof is to provide a canvas for reinforcing a conveyor belt that can be stored for a long period of time and can easily bond a treat rubber and a cover rubber. To do.

本願の請求項１に記載の発明は、コンベヤベルトを接合または補修する際に、コンベヤベルトの表面側のカバーゴムと裏面側のカバーゴムとの間に介挿される、補強用帆布本体とこの補強用帆布本体の表面及び裏面をそれぞれ覆うトリートゴムとを備えたコンベヤベルト補強用帆布であって、上記トリートゴムの表面に、表面に凹凸が設けられた凹凸付き帆布が加硫接着されていることを特徴とするものである。
請求項２に記載の発明は、請求項１に記載のコンベヤベルト補強用帆布であって、上記凹凸付き帆布は、一部が上記補強用帆布本体よりも外側にはみ出していることを特徴とする。
請求項３に記載の発明は、請求項１または請求項２に記載のコンベヤベルト補強用帆布であって、上記凹凸付き帆布が、表面側のトリートゴムと裏面のトリートゴムの両方にそれぞれ加硫接着されていることを特徴とする。 According to the first aspect of the present invention, when a conveyor belt is joined or repaired, the reinforcing canvas main body inserted between the cover rubber on the front surface side and the cover rubber on the back surface side of the conveyor belt and the reinforcement A canvas for reinforcing a conveyor belt provided with a treat rubber that covers the front and back surfaces of the canvas main body, and the surface of the treat rubber is vulcanized and bonded to the surface of the treat rubber. It is characterized by.
The invention described in claim 2 is the canvas for reinforcing a conveyor belt according to claim 1, wherein a part of the uneven canvas protrudes outward from the reinforcing canvas body. .
The invention according to claim 3 is the canvas for reinforcing a conveyor belt according to claim 1 or 2, wherein the uneven canvas is vulcanized on both the front-side treat rubber and the reverse-side treat rubber. It is bonded.

本発明によれば、補強用帆布本体とこの補強用帆布本体の表面及び裏面をそれぞれ覆うトリートゴムとを備えたコンベヤベルト補強用帆布の表面、すなわち、上記トリートゴムの表面に、凹凸を有する凹凸付き帆布を加硫接着したので、コンベヤベルトの接合または補修時には、上記凹凸付き帆布を上記トリートゴムから剥離すれば、バフ研磨を施した時のような凹凸面を有する、接着に適した上記トリートゴムの表面が露出される。したがって、バフ研磨による表面処理を行うことなく、コンベヤベルトのカバーゴムとコンベヤベルト補強用帆布とを強固に接着することができる。また、トリートゴムの表面には、バフ粉などのバフ研磨時に生じる異物が付着していないだけでなく、バフ掛け時の傷もないので、接着強度についても向上させることができる。   According to the present invention, the surface of the canvas for reinforcing a conveyor belt including the reinforcing canvas body and the treat rubber covering the front and back surfaces of the reinforcing canvas body, that is, the unevenness on the surface of the treat rubber is uneven. Since the rugged canvas is vulcanized and bonded, when the conveyor belt is joined or repaired, if the rugged canvas is peeled off from the treat rubber, it has a rugged surface as when buffing, and the above treat suitable for bonding The rubber surface is exposed. Accordingly, the cover rubber of the conveyor belt and the canvas for reinforcing the conveyor belt can be firmly bonded without performing surface treatment by buffing. Further, the surface of the treat rubber is not only free from foreign matters such as buffing, which is generated during buffing, but also has no flaws when buffing, so that the adhesive strength can be improved.

また、上記トリートゴムは加硫処理されているので、長期保存が可能なだけでなく、上記凹凸付き帆布が、コンベヤベルトの接合時に接着面となるトリートゴムの表面を覆った状態で保存されるので、本発明のコンベヤベルト補強用帆布を長期保存しても、上記トリートゴムの表面には埃がついて汚れたりすることがない。
このとき、上記凹凸付き帆布を、その一部が上記補強用帆布本体よりも外側にはみ出しているようにしておけば、上記凹凸付き帆布を上記トリートゴムから剥離するときには、上記はみ出した部分から剥離できるので、剥離の作業性が向上する。
また、上記凹凸付き帆布を、表面側のトリートゴムと裏面のトリートゴムの両方にそれぞれ加硫接着しておけば、カバーゴムとコンベヤベルト補強用帆布とを更に強固に接着することができるとともに、接着面となるトリートゴムの表面を確実に保護できる。 In addition, since the treat rubber has been vulcanized, it can be stored for a long period of time, and the canvas with unevenness can be stored in a state of covering the surface of the treat rubber that becomes an adhesive surface when the conveyor belt is joined. Therefore, even if the canvas for reinforcing a conveyor belt according to the present invention is stored for a long period of time, the surface of the treat rubber is not contaminated with dust.
At this time, if the rugged canvas is made to protrude partly outside the reinforcing canvas body, when the rugged canvas is peeled off from the treat rubber, it is peeled off from the protruding part. Therefore, the workability of peeling is improved.
In addition, if the rugged canvas is vulcanized and bonded to both the front and rear treat rubbers, the cover rubber and the conveyor belt reinforcing canvas can be bonded more firmly, The surface of the treat rubber that serves as the adhesive surface can be reliably protected.

以下、本発明の最良の形態について、図面に基づき説明する。
図１は、本最良の形態に係るコンベヤベルト補強用帆布１０の断面図で、同図において、１１は補強用帆布本体、１２ａは上側のトリートゴム、１２ｂは下側のトリートゴム、１３ａは上側の凹凸付き帆布、１３ｂは下側の凹凸付き帆布である。
上記補強用帆布本体１１は、ナイロン、ポリエステル、ビニロン、アラミド等の有機繊維から成る長尺状の部材で、この上記補強用帆布本体１１の表面１１ａ側と裏面１１ｂ側とには、それぞれ、上記上側及び下側のトリートゴム１２ａ，１２ｂが配置されている。また、上記上側のトリートゴム１２ａの上側（補強用帆布本体１１とは反対側）の面には上側の凹凸付き帆布１３ａが、上記下側のトリートゴム１２ｂの下側（補強用帆布本体１１とは反対側）の面には下側の凹凸付き帆布１３ｂが配置されている。
上記上下のトリートゴム１２ａ，１２ｂとしては、天然ゴム、ブチルゴム，スチレンブタジエンゴム（ＳＢＲ），ニトリル・ブタジエンゴム（ＮＢＲ），エチレン・プロピレンゴム（ＥＰＲ）等の合成ゴム、あるいは、これらのブレンドゴム等が用いられる。
また、上記凹凸付き帆布１３ａ，１３ｂとしては、表面に微細な凹凸１３ｍを有し、かつ、加硫ゴムとの剥離が容易であるような帆布であればよい。具体的には、Ｒmaxが２０μｍ〜２００μｍ程度であるポリエステル製の帆布が好適に用いられる。 Hereinafter, the best mode of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a conveyor belt reinforcing canvas 10 according to the best mode, wherein 11 is a reinforcing canvas body, 12a is an upper treat rubber, 12b is a lower treat rubber, and 13a is an upper side. 13b is a canvas with irregularities on the lower side.
The reinforcing canvas body 11 is a long member made of organic fibers such as nylon, polyester, vinylon, and aramid. The reinforcing canvas body 11 has a surface 11a side and a back surface 11b side, respectively. Upper and lower treat rubbers 12a, 12b are arranged. Further, the upper uneven rubber 13a is provided on the upper surface of the upper treat rubber 12a (on the side opposite to the reinforcing canvas main body 11), and the lower treatment rubber 12b is provided on the lower surface (with the reinforcing canvas main body 11). On the other side, a canvas 13b with concaves and convexes on the lower side is arranged.
The upper and lower treat rubbers 12a and 12b include natural rubber, butyl rubber, styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), synthetic rubber such as ethylene propylene rubber (EPR), or blended rubber thereof. Is used.
The canvas with unevenness 13a and 13b may be any canvas that has fine unevenness 13m on the surface and can be easily separated from the vulcanized rubber. Specifically, a polyester canvas having an Rmax of about 20 μm to 200 μm is preferably used.

上記コンベヤベルト補強用帆布１０は、図２（ａ）に示すように、上側及び下側にトリートゴム１２ａ，１２ｂを被覆した補強用帆布本体１１の上側及び下側を、更に、上記補強用帆布本体１１の幅よりも幅の広い凹凸付き帆布１３ａ，１３ｂで覆った後、加硫処理を行って、上記補強用帆布本体１１とトリートゴム１２ａ，１２ｂ、及び、トリートゴム１２ａ，１２ｂと凹凸付き帆布１３ａ，１３ｂとを加硫接着して得られる。上記加硫接着後は、図２（ｂ），（ｃ）に示すように、上記凹凸付き帆布１３ａ，１３ｂの両端部を切り取る。このとき、上記凹凸付き帆布１３ａ，１３ｂの幅が上記補強用帆布本体１１の幅よりも少し大きめになるよう切り取る。これにより、上記凹凸付き帆布１３ａ，１３ｂの幅方向端部の、上記補強用帆布本体１１よりも外側にはみ出している部分は、下記に示すように、上記トリートゴム１２ａ，１２ｂから上記凹凸付き帆布１３ａ，１３ｂを剥離する際の掴み代１３ｚとなるので、上記凹凸付き帆布１３ａ，１３ｂを上記トリートゴム１２ａ，１２ｂから容易に剥離することができる。   As shown in FIG. 2 (a), the conveyor belt reinforcing canvas 10 has an upper side and a lower side of the reinforcing canvas body 11 covered with treat rubbers 12a and 12b on the upper side and the lower side, and further the reinforcing canvas. After covering with the uneven canvas 13a, 13b wider than the width of the main body 11, vulcanization is performed, and the reinforcing canvas main body 11, treat rubber 12a, 12b, and treat rubber 12a, 12b are uneven. It is obtained by vulcanizing and bonding the canvases 13a and 13b. After the vulcanization adhesion, as shown in FIGS. 2B and 2C, both ends of the uneven canvas 13a, 13b are cut off. At this time, it cuts out so that the width | variety of the said uneven canvas 13a, 13b may become a little larger than the width | variety of the said canvas body 11 for a reinforcement. As a result, the portions of the end portions in the width direction of the uneven canvases 13a and 13b that protrude outward from the reinforcing canvas body 11 are removed from the treat rubbers 12a and 12b as described above. Since the gripping allowance 13z when peeling 13a, 13b is provided, the uneven canvas 13a, 13b can be easily peeled from the treat rubber 12a, 12b.

次に、本発明によるコンベヤベルト補強用帆布１０を用いて、上記破損したコンベヤベルトを補修する方法について説明する。まず、図３（ａ）に示すように、コンベヤベルト５０の破損した部分５０Ｘの両端部５０Ａ，５０Ｂを切り取った後、図３（ｃ）に示すように、この両端部５０Ａ，５０Ｂの間に、上記コンベヤベルト補強用帆布１０と充填用のカバーゴム５０ｃ，５０ｄとを配置するとともに、上記充填用のカバーゴム５０ｃ，５０ｄと上記コンベヤベルト補強用帆布１０との間に未加硫ゴムのシート５４ａ，５４ｂを挿入して、上記コンベヤベルト補強用帆布１０と上記充填用のカバーゴム５０ｃ，５０ｄとを加硫接着する。このとき、図３（ｂ）に示すように、予め、上記凹凸付き帆布１３ａ，１３ｂを上記トリートゴム１２ａ，１２ｂから剥離しておくことが肝要である。本例では、上記のように、上記凹凸付き帆布１３ａ，１３ｂに掴み代１３ｚが設けてあるので、上記凹凸付き帆布１３ａ，１３ｂをトリートゴム１２ａ，１２ｂから剥離する際には、上記掴み代１３ｚを把持するようにすれば、剥離作業を容易に行うことができる。
上記凹凸付き帆布１３ａ，１３ｂは上記トリートゴム１２ａ，１２ｂと加硫接着されているので、上記トリートゴム１２ａ，１２ｂの表面には、加硫時において、上記凹凸付き帆布１３ａ，１３ｂの表面の凹凸１３ｍとほぼ同じ凹凸１２ｍが形成されている。上記凹凸１２ｍの大きさは、上述したように、Ｒmaxが２０μｍ〜２００μｍと、トリートゴム１２ａ，１２ｂをバフ研磨した時と同じ程度である。したがって、上記未加硫ゴムのシート５４ａ，５４ｂが加硫されるときに、上記未加硫ゴムのシート５４ａ，５４ｂのゴム部材と上記凹凸付き帆布１３ａ，１３ｂを剥離したコンベヤベルト補強用帆布１０のトリートゴム１２ａ，１２ｂとの間の接着強度を高めることができるので、上記充填用のカバーゴム５０ｃ，５０ｄと上記コンベヤベルト補強用帆布１０との接着を強固にすることができる。
また、上記コンベヤベルト補強用帆布１０は、通常、リールなどに巻取って保存されるが、このコンベヤベルト補強用帆布１０のゴム部材であるトリートゴム１２ａ，１２ｂは既に加硫処理されているので、長期保存が可能である。
また、コンベヤベルトの接合時に接着面となる上記トリートゴム１２ａ，１２ｂの表面は、上記凹凸付き帆布１３ａ，１３ｂにより覆われているので、保存中に上記トリートゴム１２ａ，１２ｂの表面に埃がついて汚れたりすることはない。したがって、上記トリートゴム１２ａ，１２ｂの表面を清浄な状態で保存することができる。 Next, a method for repairing the damaged conveyor belt using the conveyor belt reinforcing canvas 10 according to the present invention will be described. First, as shown in FIG. 3 (a), both end portions 50A and 50B of the damaged portion 50X of the conveyor belt 50 are cut off, and then between the both end portions 50A and 50B as shown in FIG. 3 (c). The conveyor belt reinforcing canvas 10 and the filling cover rubbers 50c, 50d are arranged, and a sheet of unvulcanized rubber is provided between the filling cover rubbers 50c, 50d and the conveyor belt reinforcing canvas 10. 54a and 54b are inserted to vulcanize and bond the conveyor belt reinforcing canvas 10 and the filling cover rubbers 50c and 50d. At this time, as shown in FIG. 3 (b), it is important that the uneven canvases 13a and 13b are previously peeled off from the treat rubbers 12a and 12b. In the present example, as described above, the gripping allowance 13z is provided on the uneven canvas 13a, 13b. Therefore, when the uneven canvas 13a, 13b is peeled from the treat rubber 12a, 12b, the grip allowance 13z. If it is made to hold | grip, peeling work can be performed easily.
Since the uneven canvases 13a and 13b are vulcanized and bonded to the treat rubbers 12a and 12b, the surface of the treat rubbers 12a and 12b is uneven on the surfaces of the uneven canvases 13a and 13b during vulcanization. Irregularities 12m that are substantially the same as 13m are formed. As described above, the size of the unevenness 12m is 20 μm to 200 μm, which is about the same as when the treat rubbers 12a and 12b are buffed. Therefore, when the unvulcanized rubber sheets 54a and 54b are vulcanized, the rubber member 10 of the unvulcanized rubber sheets 54a and 54b and the uneven canvas 13a and 13b are peeled off from the canvas 13 for reinforcing a conveyor belt. Since the adhesive strength between the treating rubbers 12a and 12b can be increased, the adhesion between the filling cover rubbers 50c and 50d and the conveyor belt reinforcing canvas 10 can be strengthened.
The conveyor belt reinforcing canvas 10 is usually stored on a reel or the like, but the treat rubbers 12a and 12b, which are rubber members of the conveyor belt reinforcing canvas 10, have already been vulcanized. Long-term storage is possible.
Further, the surface of the treat rubber 12a, 12b, which becomes the adhesive surface when the conveyor belt is joined, is covered with the uneven canvas 13a, 13b. It won't get dirty. Therefore, the surfaces of the treat rubbers 12a and 12b can be stored in a clean state.

このように、本実施の形態によれば、コンベヤベルトを補修して接合する際に用いられるコンベヤベルト補強用帆布１０を、長尺状の補強用帆布本体１１と、この補強用帆布本体１１の表面１１ａ側と裏面１１ｂ側とに配置された上側及び下側のトリートゴム１２ａ，１２ｂと、これらのトリートゴム１２ａ，１２ｂの表面に配置された、表面に微細な凹凸を有し、かつ、加硫ゴムとの剥離が容易な帆布から成る上側及び下側の凹凸付き帆布１３ａ，１３ｂとを一体に加硫接着して作製したので、コンベヤベルト５０の接合時には、上記凹凸付き帆布１３ａ，１３ｂを上記トリートゴム１２ａ，１２ｂから剥離しただけで、コンベヤベルト５０のカバーゴムとなる充填用のカバーゴム５０ｃ，５０ｄと上記コンベヤベルト補強用帆布１０とを強固に接着することができる。
また、上記トリートゴム１２ａ，１２ｂは加硫処理されているので、長期保存が可能なだけでなく、トリートゴム１２ａ，１２ｂの表面は上記凹凸付き帆布１３ａ，１３ｂにより覆われているので、上記トリートゴムの表面を清浄に保つことができる。
また、上記凹凸付き帆布１３ａ，１３ｂに掴み代１３ｚを設けたので、剥離の作業性が向上した。 As described above, according to the present embodiment, the conveyor belt reinforcing canvas 10 used for repairing and joining the conveyor belt is divided into the long reinforcing canvas body 11 and the reinforcing canvas body 11. The upper and lower treat rubbers 12a, 12b arranged on the front surface 11a side and the back surface 11b side, and the surface of these treat rubbers 12a, 12b, which have fine irregularities on the surface and are processed Since the upper and lower uneven canvases 13a and 13b made of a canvas that can be easily peeled off from the vulcanized rubber are integrally vulcanized and bonded, when the conveyor belt 50 is joined, the uneven canvases 13a and 13b are formed. The cover rubber 50c, 50d for filling, which becomes the cover rubber for the conveyor belt 50, and the canvas 10 for reinforcing the conveyor belt are simply separated from the treat rubber 12a, 12b. They can be adhered to the solid.
Further, since the treat rubbers 12a and 12b are vulcanized, not only can they be stored for a long period of time, but also the surface of the treat rubbers 12a and 12b is covered with the uneven canvases 13a and 13b. The rubber surface can be kept clean.
Moreover, since the gripping allowance 13z is provided on the uneven canvas 13a, 13b, the workability of peeling is improved.

なお、上記最良の形態では、コンベヤベルト補強用帆布１０を用いて、破損したコンベヤベルトを補修する方法について説明したが、本発明は、コンベヤベルトの補修に限ったものではなく、帯状のベルト部材をループ状に接合して新たなコンベヤベルトを作製する場合にも適用可能である。
また、上記例では、補強用帆布本体１１として、アラミド繊維等の帆布を用いたコンベヤベルトについて説明したが、本発明は、上記補強用帆布本体１１に代えて、スチールコードをトリートゴムで被覆したものを補強部材として用いたコンベヤベルトについても適用可能である。
また、上記例では、補強用帆布本体１１が１層である例を示したが、本発明は、補強用帆布本体１１が２層あるいは３層以上である場合にも適用可能である。
また、上記例では、トリートゴム１２ａ，１２ｂの両面に凹凸付き帆布１３ａ，１３ｂを加硫接着したが、コンベヤベルトがプーリに接触する側に相当する下側のトリートゴム１２ｂのみに設けてもよい。 In the above-described best mode, the method of repairing a damaged conveyor belt using the conveyor belt reinforcing canvas 10 has been described. However, the present invention is not limited to repairing a conveyor belt, but a belt-like belt member. It is also applicable to the case where a new conveyor belt is manufactured by joining the belts in a loop shape.
In the above example, a conveyor belt using canvas such as aramid fibers has been described as the reinforcing canvas body 11. However, in the present invention, instead of the reinforcing canvas body 11, the steel cord is covered with treat rubber. The present invention can also be applied to a conveyor belt using a reinforcing member as a reinforcing member.
In the above example, the reinforcing canvas body 11 has one layer. However, the present invention can also be applied to the case where the reinforcing canvas body 11 has two layers or three or more layers.
