| Full Text | The present invention relates to conveyor belt with ball-type reinforcement on the backing side. The invention relates to a conveyor belt having a bearing side and a backing side made of elastomer material, as well as an embedded reinforcement carrier, particularly in the form of steel cables or steel cords, or a one-layer or multi-layer reinforcement carrier. In this regard, reference is made to the following prior art, for example: DE 25 32 190 C2, DE 38 01 120 C2, DE 37 35 024 Al, and DE 38 02 963 Al. Within the scope of a further development, the task consists in making available a conveyor belt having an improved indentation rolling resistance, which therefore results in a lower demand for energy. This task is accomplished by means of the characterizing part of claim 1, in that the backing side is reinforced with ball-type elements. Practical embodiments of the invention are indicated in claims 2 to 20. The invention will now be described on the basis of an exemplary embodiment, making reference to a drawing that shows the cross-section of a conveyor belt. 2 The conveyor belt 1 comprises a bearing side 2 and a backing side 3, which consist of an elastomer material, in each instance. The conveyor belt furthermore has an embedded reinforcement carrier 4 in the form of steel cables. The backing side 3 is reinforced with ball-type elements 5 that are disposed within a single layer 6. This layer, in the form of an elastomer matrix, runs close to the reinforcement carrier 4, whereby the ball-type reinforcement extends essentially over the entire width of the conveyor belt. Furthermore, the ball-type elements have essentially the same diameter, whereby the diameter of the ball-type elements corresponds approximately to the layer thickness. The particular feature of this backing side 3 reinforced by ball-type elements 5 lies in the round surface of the ball-type elements that are introduced, which lead to a lesser indentation rolling resistance. The running properties of the conveyor belt are improved, and this contributes to a reduced demand for energy. The backing side reinforced with ball-type elements is also referred to as a damping ball-type element mat. The following tables state the practical diameter and density range of the ball-type elements and the elastomer densities, in Table 1, on the one hand, as well as concrete experimental data within these ranges in Table 2, on the other hand. The thickness of the reinforcement layer corresponded to the diameter of the ball-type elements in all the experiments. 4 Reference Symbol List 1 conveyor belt 2 bearing side (cover plate on bearing side) 3 backing side (cover plate on backing side) 4 reinforcement carrier (steel cables) 5 ball-type elements 6 layer of the ball-type elements (reinforcement layer) WE CLAIM: 1.
