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.

Flexurally elastic drive belt

The invention relates to an article including an elastic main body on the basis of a vulcanized rubber () having an article surface that is susceptible to wear, which is provided with a textile layer. The textile layer, particularly a woven fabric () or knitted fabric, has a mesh design that allows the vulcanized rubber () to penetrate to the textile surface to form a textile-vulcanized rubber hybrid system (), wherein the vulcanized rubber portion on the textile surface can be controlled by means of the stitch number, stitch width and the thread design of the textile layer. The article is in particular a drive belt and in connection with the primary intended use, a method for making a drive belt is provided.

Article, particularly drive belt, having a textile layer and method for producing a drive belt

V-ribbed belts are formed by thermoplastic shaping and contain ribs that run at least on a first side in a longitudinal direction of the V-ribbed belt. The first side contains a layer composed of a textile warp-knit fabric made up of two different yarns. The warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5N/1000 dtex, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, both based on 5% extension. The first and second yarns form a coherent network and the yarns do not twine around one another. V-ribbed belts can be formed using an elastic warp-knit fabric, whose extension is based on the construction of the knitted fabrics. The belts maintain better noise reduction both in the new state and after a relatively long service life.
