Abstract (en)
A problem encountered in increasing the tensile strength of conveyor belting is that when the belting is made thicker to increase its strength, it becomes difficult to impregnate the interior of the belting carcass. To overcome this difficulty, the invention provides a method for manufacturing solid woven beltings which comprises weaving a textile fabric carcass having a plurality of integrally woven layers of weft and subsquently impregnating and coating said carcass with a polymeric material, the textile carcass having five or seven integrally woven layers of weft and being woven in such a manner that the warp yarns define a plurality of continuous flow paths along which the impregnant can travel from the outer surfaces of the carcass to the interior core and each of the warp yarns defines such a path. The weft layers may be interlocked solely by dual function warp yarns all of which serve simultaneously to impart tension resistant strength to the fabric.
