  • Patent number: 9709128
    Abstract: The invention relates to an article including an elastic main body on the basis of a vulcanized rubber (17) having an article surface that is susceptible to wear, which is provided with a textile layer. The textile layer, particularly a woven fabric (16) or knitted fabric, has a mesh design that allows the vulcanized rubber (17) to penetrate to the textile surface to form a textile-vulcanized rubber hybrid system (15), 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.

  • Patent number: 8507391
    Abstract: An article has an elastic main element based on a vulcanizate having a wear-susceptible article surface. The article is primarily a drive belt (8) having a top layer (9) as the belt rear and a substructure (10) having a force transmission zone (13), wherein the force transmission zone and/or the top layer is/are supplied with a textile overlay (15), wherein the textile overlay is in turn additionally prepared with a plastic. The plastic is a bonding agent that is arranged between the main body and the textile overlay (15), wherein the plastic is supplied such that it melts during vulcanization and penetrates into the textile overlay while bonding, connected to a permanent adhesive bond between main body and textile overlay. A cotton fabric is used as the textile overlay (15), for example. The plastic is in the form of a film, for example, particularly in the form of a PE film. The primary purpose of use is the V-belt, ribbed V-belt (8) and the toothed belt.
