Abstract: A toothed belt includes a front rubber layer having teeth formed in the front rubber layer. A plurality of short fibers are entirely distributed in the front rubber layer. A first side of the front rubber layer is covered with a cover fabric. A back rubber layer contacts a second side of the front rubber layer. A plurality of cord elements extend along a length of the belt and are interposed between the front rubber layer and the back rubber layer in such a manner that a portion of each cord element is embedded in the front rubber layer, and the remaining portion of each cord element is embedded in the back rubber layer. Additionally, that portion of the plurality of short fibers that is positioned in a peripheral area of the front rubber layer adjacent to the upper surface of the front rubber layer is substantially parallel to an upper surface of each tooth of the front rubber layer, and another portion of the short fibers that is positioned in a central area of each tooth of the front rubber layer is substantially perpendicular to the lower surface of the front rubber layer.
