The invention relates to a conveying device (2) comprising a continuous conveyor belt (1) having a multi-layer structure consisting of a layer (5) that forms a load-bearing side and a layer (6) that forms a running side. An adhesion layer (8) between said layer (6) and the tension member has a composition having a first portion of an adhesive and having a second portion of a lubricant. The invention is based on the knowledge that the cohesive strength between the layer (6) forming the running side and the layer (7) forming the tension member is not reduced as a result of the composition introduced therebetween, but rather a lubricant portion penetrates the running side and is deposited on the outside of the layer (6).
