ABSTRACT:
A reinforcing fabric for reinforcing power transmission belts is comprised of a first fibrous web having minimal warp yarns and filler yarns oriented at a desired right lead. A second fibrous web is provided which has minimal warp yarns and filler yarns oriented at a desired left lead. The first and second fibrous webs are interconnected either mechanically, chemically, or both, so that an angle of between 178.degree. and 60.degree. is formed between the filler yarns of the first fibrous web and the filler yarns of the second fibrous web when viewed in the direction of tension on the power transmission belt. The resulting reinforcing fabric may be formed in the belt direction so that banner cutting is eliminated. This makes it possible to make an endless belt with only one splice.
