Abstract: The invention provides a method for manufacturing textile reinforced conveyor beltings comprising subjecting the outer surfaces of a textile carcass constituted wholly of synthetic fibre yarns, or comprising at least a major proportion of synthetic fibre yarns, to a brushing or raising action so as to break and raise or to roughen a proportion of the filaments in the extreme outer yarns prior to impregnation and/or coating of the carcass, for example with PVC or rubber or other polymeric or elastomeric material, so as to improve bondability between the synthetic fibre and the impregnating or coating material.
