Abstract:
A toothed belt comprising:a front rubber layer having a plurality of teeth formed therein and containing a plurality of short fibers entirely distributed in a non-random manner within said front rubber layer, said plurality of teeth being spaced a part from one another along a length of said front rubber layer, each said tooth extending in a width direction of said front rubber layer, said front rubber layer having an upper surface and a lower surface, each said tooth having an upper surface coincident with said upper surface of said front rubber layer;a cover fabric covering said upper surface of said front rubber layer;a back rubber layer, discrete from said front rubber layer, contacting said lower surface of said front rubber layer; anda plurality of cord elements each extending along the length of said front rubber layer and being interposed between said front rubber layer and said back rubber layer such that a portion of each said cord element of said plurality of cord elements is embedded in said front rubber layer, and a remaining portion of each said cord element is embedded in said back rubber layer,wherein a portion of said plurality of short fibers is positioned in a peripheral area of each said tooth adjacent to said upper surface of each said tooth and is substantially parallel to said upper surface of each said tooth of said front rubber layer, and the remaining portion of said short fibers is positioned in a central area of each said tooth of said front rubber layer and is substantially perpendicular to said lower surface of said front rubber layer.
