Abstract: The present invention relates to elastomer toothed belts comprising a fabric spanning the teeth of the toothed belt, wherein the elastomer mixture forming the teeth contains a crosslinked ethylene-propylene rubber (EPM) and/or a crosslinked ethylene-propylene terpolymer rubber (EPDM) accounting for at least 70% by weight of the elastomer mixture based on the polymer proportion and wherein an interlayer is arranged between the fabric and the elastomer mixture forming the teeth which contains at least 70% by weight of hydrogenated acrylonitrile-butadiene rubber (HNBR) based on the polymer proportion of the interlayer. Such elastomer toothed belts are halogen-free and feature improved durability and good low-temperature stability properties. The present invention further relates to processes for producing such elastomer toothed belts and to the use of a layer of hydrogenated acrylonitrile-butadiene rubber (HNBR) in such toothed belts to increase service life, to improve low-temperature stability and to improve the adhesion between the teeth and the fabric.

Abstract: The present invention relates to a process for adhering a textile material to an elastomer, the process comprising the steps of pretreating the textile material with at least one polyester of an α-β-unsaturated carboxylic acid, contacting the pretreated textile material with an unvulcanized elastomer, and vulcanizing the product obtained. The present invention additionally encompasses an elastomer article obtainable by this process and also the use of a polyester of an α-β-unsaturated carboxylic acid for improving the adhesion of a textile material to an elastomer.

Abstract: The invention relates to a drive belt (1) having a main body into which one or more tension strands (3) composed of para-aramid in cord construction are embedded, wherein each tension strand (3) has twisted plies each formed from at least one twisted yarn, and wherein the turning direction of the respective ply (first twist) is the opposite of the turning direction of the cord (final twist).
It is a feature of the invention that the tension strands (3) each have at least four plies, wherein the twist factor TM1 of the plies (first twist) is between 4.5 and 5.4, and the twist factor TM2 of the cord (final twist) is between 2.7 and 3.8, and the ratio of the twist factor of the plies to the twist factor of the cord (TM1/TM2) is between 1.3 and 1.5.-
