<p>An endless power transmission belt comprising a plurality of V-belt parts spaced laterally apart from one another and tie band having an improved structure and connecting the V-belt parts together. The V-belt part and the tie band are essentially made of elastomer material and fabrics. More specifically, the tie band is made up of at least two cord fabric layers and an elastomer material in which the cord fabric layers are embedded. An intermediate elastomer material layer is provided between the fabric layers. The fabric layers are made of cords which are extended obliquely with respect to the longitudinal axis of the belt in such a manner that the cords forming one fabric layer form an angle with the cords forming another fabric layer adjacent thereto. The upper surfaces of the plurality of V-belt parts are connected by the tie band thus constructed, to form one unit.</p> |
