噛み込んだ状態となり、コードが上下に動くことになる
。そこで、帆布を設ける事が考えられるが、そのように
すると、帆布のジヨイント部でコードが乱れ、また、帆
布のジヨイントで剛性が変化するために、回転むらが大
きく、精度が要求される薄厚のベルトとしては適用する
ことができない。(Problem to be solved by the invention) However, in such belts, an unvulcanized rubber sheet is wrapped directly around the mold, and a cord is wrapped around it, so the mold release agent expands during vulcanization and generates gas. However, there is no place for the gas (steam) to escape in the width direction of the cord, and the gas becomes trapped, causing the cord to move up and down. Therefore, it may be possible to use canvas, but in this case, the cords would be disturbed at the joints of the canvas, and the rigidity would change at the joints of the canvas, resulting in large rotational irregularities. It cannot be used as a belt.
また、コードを支持するために、金型に接する側のゴム

ドの沈み込みが大きく発生する一方、金型側のゴム部の
厚さを薄くすると、波打ちを生ずる。In addition, if the thickness of the rubber part on the side in contact with the mold is increased to support the cord, the cord will sink significantly due to the flow of rubber during vulcanization, while the thickness of the rubber part on the mold side If it is made thinner, waving will occur.
本発明はかかる点に鑑み、製造が容易で、精度良く製造
