Provided is a conveyor belt. The upper cover rubber has a configuration in which a wear resistance layer and an impact resistance layer are layered in this order from an outer peripheral side of the conveyor belt. The wear resistance layer has a loss coefficient of from 0.03 to 0.25 and a loss elastic coefficient of from 0.20 MPa to 6.50 MPa at 20 C. The impact resistance layer has a loss coefficient of from 0.15 to 0.70 and a loss elastic coefficient of from 1.5 MPa to 30.0 MPa at 20 C.

A method for attaching a connector element to a belt end of a conveyor belt, wherein the connector element has a base tier and an adhesive tier which is disposed on one side of the base tier and produces adhesive under the effect of heat, the base tier in a central region being provided with passages, includes (i) disposing the connector element on the belt end, wherein the connector element positioned in a U-shaped deflection is disposed on averted sides of the belt and on one end side of the belt, wherein the passages are positioned in the region of the U-shaped deflection of the connector element, and the adhesive tier is disposed on the belt so as to face the averted sides of the belt (1); and (ii) connecting the connector element to the belt in the region of the averted sides of the belt, wherein the connector element is adhesively bonded to the belt under the effect of a heated pressing installation that is disposed on both sides of the belt.

The invention relates to a method for making conveyor belts in an apparatus having a vulcanizing press. The method minimizes the press opening times and the throughput of the press is thus optimized. With the method, a check is made during the method whether a conveyor belt blank is present for vulcanizing in the press, and depending on the information from this check, the decision is made as to how far the press opens the press plates. Here, an operating open position and a full opening of the press are provided.
