| 摘要 |
The invention relates to a belt (43) with at least two fibre strands (41) which have synthetic fibre threads twisted in themselves and are designed for acceptance of force in longitudinal direction. The strands (41) are arranged at a spacing relative to one another along the longitudinal direction of the belt (43) and embedded in a belt casing (45). At least one of the strands (41) comprises an electrically conductive indicator thread (44) which is twisted together with the synthetic fibre threads of the strand (41), wherein the indicator thread (44) is arranged outside the centre of the fibre bundle (41). The indicator thread (44) has a breaking elongation (.epsilon.ult,lnd) which is smaller than the breaking elongation (.epsilon.ult,Trag) of individual synthetic fibre threads of the strand (41). It can be electrically contacted so that an electrical monitoring of the integrity thereof is made possible. |
