    • A method of manufacturing flexible belts from fibers. Fibers that form the flexible belt are soaked with a liquid elastomer. The liquid elastomer soaked fibers are formed into the shape of a belt, beneficially by wrapping the fibers around a mandrel. The belt-shaped and soaked fibers are then cured. Multiple layer flexible belts can be formed by soaking fibers with a first liquid elastomer, wrapping those fibers around a mandrel, and then curing the mandrel to form a belt layer. Then, fibers are soaked with a second liquid elastomers. Those soaked fibers are then wrapped around the mandrel/belt layer. The fibers soaked with the second elastomer are then cured, forming a belt having two layers. The formed belt is then removed from the mandrel. The fibers and liquid elastomer(s) are beneficially chosen to introduce desirable belt properties.
    • 从纤维制造柔性带的方法。 形成柔性带的纤维用液体弹性体浸泡。 浸渍纤维的液体弹性体形成带状,有利地将纤维缠绕在心轴上。 然后将带状和浸泡的纤维固化。 多层柔性带可以通过将纤维与第一液体弹性体相混合而形成,将这些纤维缠绕在心轴上,然后固化心轴以形成带束层。 然后,纤维用第二液体弹性体浸泡。 然后将那些浸泡的纤维缠绕在心轴/带束层周围。 然后将用第二弹性体浸泡的纤维固化,形成具有两层的带。 然后将形成的带从心轴移除。 有利地选择纤维和液体弹性体以引入期望的带性质。
