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.
Claims10
A conveyor belt comprising a flat body of flexible material;
- a multiplicity of longitudinally extending reinforcing strands embedded in said body and lying in at least one plane therein;
- and a longitudinal-tear barrier embedded in said body at least above said strands, said barrier comprising a fabric layer having interwoven threads running in the longitudinal direction of the belt and transversely thereof, the tensile strength of the transversely running threads being at least eight times greater than the tensile strength of the longitudinally running threads.
