An endless power transmission belt construction (20), cord (27) therefor and method of making the same are provided, the cord having the yarns (33) and the plies (32) therefor respectively twisted on a 2 for 1 twister so as to cause the longitudinal axes of the fiber filaments (34) to be disposed generally in the longitudinal direction of the cord (27) with the denier of the fiber filaments of each yarn (33) being approximately 1500, the twist multiplier for the three plies (32) being 3.7687 as the three plies are twisted together at a rate of approximately 2.9 turns per linear inch of the cord (27), the twist multiplier for the two yarns (33) being 3.6765 as the two yarns for each ply (32) are twisted together at a rate of approximately 4.9 turns per linear inch of that ply, and the fiber filaments (34) comprising p-aramid that comprises co-poly (paraphenylene/3,4' oxydiphenylene terephthalamide).
Structure (20) de courroie de transmission en boucle, câble (27) destiné à cet usage et méthode d'élaboration de ce câble, dont les fils (33) et les nappes (32) sont respectivement tordus sur une tordeuse à 2 pour 1, afin que les axes longitudinaux des filaments de fibre (34) soient disposés essentiellement dans le sens longitudinal du câblé (27), le denier des filaments fibreux de chaque fils (33) étant approximativement étant de 1500, le multiplicateur de torsion pour les trois nappes (32) de 3,7687 lorsque les trois nappes sont tordues ensemble sous un rapport d'environ 2,9 tours par pouce linéaire de câblé (27), le multiplicateur de torsion pour les deux fils (33) étant de 3,6765 alors que les deux fils de chaque nappe (32) sont tordus ensemble sous un rapport d'environ 4,9 tours par pouce linéaire de cette nappe, et les filaments fibreux (34) comprenant de la p-aramide renfermant un co-poly (paraphénylène/3,4' oxydiphénylène téréphthalamide).
