<p>The invention pertains to a transmission belt comprising a cord, a rubber or thermoplastic matrix, and an adhesion material which is able to adhere the cord to the rubber or thermoplastic matrix, characterized in that the cord is made of at least two yarns, the first being a yarn with a melting or decomposition point T1 and the second being a yarn with a melting point T2, wherein T1⊃T2 and the ratio of the linear density of the first yarn to the linear density of the second yarn is between 1,000:1 and 1:1, wherein the second yarn is fused to the first yarn. The invention also pertains to a method in which the first and the second yarn are intertwined and then heated at a temperature between T1 and T2, with the heating step being integrated with or followed by a step wherein the cord is subjected to a dipping treatment with a rubber adhesion material and to a method of making transmission belts using said cords.</p> |
