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.
