Abstract
A flexurally elastic drive belt () has a cover layer (), a reinforcement layer () formed of individual cords () and a substructure (). The substructure can include ribs () and grooves (). The drive belt is further provided with a textile overlay on the working side () thereof that is susceptible to wear. The textile overlay (; section B of FIG.) of the drive belt () combines a very durable resistance to wear and a noise attenuation especially for wet noises. This is achieved in that the overlay has, in a state in advance of fabrication and vulcanization, an elongation at tear of at least 30% in the longitudinal direction and of at least 100% in the transverse direction and is made of a textile material including staple fibers in a proportion in terms of quantity of at least 30% by weight.
