Therefore, the rubber component can be appropriately left on the surface of the fiber reinforcement layer regardless of the direction in which the rubber is peeled off. Therefore, it is possible to firmly join the belt end portions in the belt longitudinal direction by vulcanizing the rubber components remaining in the belt end portions in the belt longitudinal direction with a vulcanizing adhesive or the like interposed therebetween.

- a sufficient amount of rubber component is formed on the surface of the fiber reinforcing layer 3 after the peeling operation. R remains, and it is possible to firmly join the end portions 1a in the longitudinal direction.
- the warp 4 is thinned (the fineness F1 of the warp 4 is reduced), the arrangement density of the warps 4 is reduced, and the weft 5 is thickened (the fineness F2 of the weft 5 is decreased).
- There are options such as increasing the arrangement density of the weft threads 5.
- the warp yarns 4 are too thin or the arrangement density of the warp yarns 4 is too small, there arises a problem that it is difficult to ensure the strength of the fiber reinforcing layer 3 in the belt longitudinal direction.

- Polyamide fiber has better adhesion to rubber than polyester fiber. Therefore, by using a polyester fiber for the warp 4 and a polyamide fiber for the weft 5, it is possible to further improve the adhesion between the rubber and the fiber reinforcing layer 3 when the rubber is peeled in the belt width direction. Become advantageous.
- all the fiber reinforcement layers may be the fiber reinforcement layers 3 of the present invention.
- the layer 3 can be used, and the remainder can be an inexpensive general-purpose fiber reinforced layer.

- the strength utilization factor F of the warp calculated by the following equation (2) was determined.
- Strength utilization factor F (Strong breaking strength of warp per unit width of fiber reinforcing layer / (Tensile breaking strength of one warp ⁇ Number of warp per unit width of fiber reinforcing layer)) ⁇ 100% (2)
- the strength utilization factor F is an index indicating how much the tensile strength inherent in warp yarns can be exhibited in the fiber reinforcement layer, and the greater the value of F, the more efficiently the warp yarn strength is exhibited efficiently. It means that it is excellent.
- Table 1 the strong utilization rate of the conventional example is evaluated as an index with a standard of 100, and the larger index value means the better.
- test Specimens were produced according to JIS K 6256-1: 2013 “Peel strength from fabric” using samples of the respective fiber reinforcing layers.
- the test piece was obtained by vulcanizing and integrating each sample between an adhesive rubber (NR weight ratio 50%) and a cover rubber (NBR weight ratio 20%, SBR weight ratio 40%). Then, in accordance with JIS K 6256-1: 2013 “Peel strength from cloth”, the sample and the adhesive rubber were peeled off, and the area of the adhesive rubber remaining on the bonding surface of the sample with the adhesive rubber was measured. did.
- the sample was peeled in two directions, ie, the belt longitudinal direction (warp yarn extending direction) and the belt width direction (weft extending direction).
- test conditions for each test piece were the same except that the fiber reinforced layer was different.
- the area of the remaining adhesive rubber is evaluated by an index with the conventional example being 100 as the standard, and a larger index value means that the remaining amount of the adhesive rubber is larger and superior.
- Examples 1 to 5 have the same performance as the conventional example with respect to the rate of change with time in belt length, fatigue resistance, and the strength utilization factor of warp, and the rubber and the fiber reinforcement layer are arranged in the belt width direction. It can be seen that much more rubber remains in the fiber reinforced layer than in the conventional example when peeling toward.

Abstract
Description
撚り係数T1=(T/10)×(D)1/2 ・・・(1)
この(1)式のTは横糸5の10cm当たりの撚り数、Dは横糸5の繊度(dtex)である。
それぞれのコンベヤベルトのサンプルを同条件でプーリ間に張設して、同条件で走行試験を行い、走行前と走行後でのサンプルの周長の変化率を測定した。変化率は従来例を基準の100として指数で評価し、指数の数値が小さい方が経時的な周長の増大が抑制されて優れていること意味する。
走行前のそれぞれのコンベヤベルトのサンプルについて、下記(2)式により算出される縦糸の強力利用率Fを把握した。
強力利用率F=(繊維補強層の単位幅当たりの縦糸の延在方向破断強力/(1本の縦糸の引張破断強力×繊維補強層の単位幅当たりの縦糸の本数))×100%・・・(2)
強力利用率Fは、繊維補強層において縦糸が本来有している引張強力をどの程度発揮できるかを示す指標であり、Fの数値が大きい方が縦糸の強力が無駄なく効率的に発揮されていて優れていること意味する。表1では従来例の強力利用率を基準の100として指数で評価し、指数の数値が大きい方が優れていることを意味する。
それぞれの繊維補強層のサンプルを用いてJIS K 6256-1:2013「布との剥離強さ」に準拠して試験片を製造した。試験片は接着ゴム(NR重量比率50%)とカバーゴム(NBR重量比率20%、SBR重量比率40%)の間にそれぞれのサンプルを挟んで加硫して一体化させたものである。そして、JIS K 6256-1:2013「布との剥離強さ」に準拠してサンプルと接着ゴムとの間を剥離させて、サンプルの接着ゴムとの接合面に残存した接着ゴムの面積を測定した。サンプルを剥離させる方向は、ベルト長手方向(縦糸の延在方向)とベルト幅方向(横糸の延在方向)の2通りで行った。即ち、それぞれの試験片は繊維補強層が異なるだけで試験条件は共通にした。残存した接着ゴムの面積は従来例を基準の100として指数で評価し、指数の数値が大きい方が接着ゴムの残存量が多くて優れていること意味する。
