Abstract
A conveyor belt with continuous longitudinal reinforcement strands has a mechanical transverse barrier to prevent longitudinal ripping slitting or tearing. The mechanical transverse barrier is a fabric with warp and weft threads embedded in a cover layer of the conveyor belt. The longitudinally running threads have a substantially lower tensile strength than the transversely running threads, i.e. the tensile strength of the transverse threads is at least 8 times that of the longitudinal threads and preferably upwards of 20 (e.g. 30 to 50) times that of the longitudinal threads.
