Patent number: 8262523Abstract: 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.Type: GrantFiled: June 20, 2008Date of Patent: September 11, 2012Assignee: ContiTech Antriebssysteme GmbHInventors: Henning Kanzow, Claus-Lüder Mahnken, Tobias Nonnast, Marko Schleicher, Reinhard Teves
