Problems solved by technology

This covering leads to forming problems in the forming process during the production of the ribbed V-belt, while the noise behavior is insufficient especially when wet and above all the bending flexibility is always insufficient at low temperatures
[0003] These numerous solutions for the coating of drive belts show that the development in this regard is not yet over

Embodiment Construction

[0056] The invention will now be explained by means of an exemplary embodiment with reference to the schematic drawings.

[0057] The only figure shows a drive belt 1, which is formed as a ribbed V-belt, with a cover layer 2 as the belt back, a reinforcing fabric layer and a substructure 4, the reinforcing fabric layer has a Tensile carriers 3 in the form of individual threads arranged running parallel in the longitudinal direction. The covering layer and the substructure constitute the elastomeric matrix based on a cured substance, for example based on EPDM. The substructure has a multi-wedged triangular structure consisting of wedges 5 and grooves 6 . The substructure here includes the force transmission region 9 .

[0058] The covering 8 (here only covering the force transmission region 9 and the wedge portion 7 ) consists only of a single-layer LLDPE foil. Here, the LLDPE foil is applied to the substructure mixture prior to packaging.

[0059] The tensile carrier 3 is ...

Abstract

Article comprises an elastic base body based on a vulcanizate with a wear-prone article surface, which is provided with a coating (8). At least one surface coating of the article is made of at least one film. The film comprises at least 50 wt.% linear low density polyethylene (LLDPE). The film melts during vulcanization and forms a solid adhesive bond of the base body and coating. The article is a drive belt (1) comprising a belt back (2), a top layer mixture and a base (4) with a force transmission zone (9). At least one force transmission zone is provided with the coating. An independent claim is also included for producing the article, comprising applying the film containing at least 50 wt.% LLDPE to the mixture of the base, before packaging the article.

Description

technical field [0001] The present invention relates to an article with an elastomeric matrix based on a cured mass, with a wear-sensitive The surface of the article is provided with a covering. The elastic base is usually also provided with an embedded reinforcing fabric or stretch carrier which can be embodied as a single layer or as multiple layers. Background technique [0002] An item exposed to dynamic loads and thus to wear and noise generation, such as drive belts, conveyor belts or air spring bellows, wherein drive belts are of particular importance. The elastic base body of the drive belt here comprises a covering as the rear side of the belt and an understructure with the force transmission area. The drive belt, which is an intensive use area, is provided with a covering, in particular in the area of ​​this force transmission area, in order to reduce noise and increase wear resistance. Various covering types are known for this purpose. A lacquer covering base...
