Patent ID: 7326139

Claim:
A belt with at least two strands which comprise synthetic fiber threads twisted in themselves and which are designed for acceptance of force in a longitudinal direction, wherein the strands are arranged parallel to one another along a longitudinal direction of the belt and at a spacing from one another and are embedded in a belt casing, comprising: at least one of the strands including an electrically conductive indicator thread which is twisted together with the synthetic fiber threads of the at least one strand; and wherein said indicator thread has a breaking elongation (ε ult,Ind ) which is smaller than a breaking elongation (ε ult,Trag ) of individual ones of the synthetic fiber threads of the strand and is adapted to be electrically contacted so as to enable an electrical monitoring of the integrity of the indicator thread, and wherein a boundary value of said at least one strand is less than or equal to 0.88.
