The invention comprises a belt having a plied construction overlying tensile cords. An elastomeric layer (10) overlies an overcord (11) which overlies yet another elastomeric layer (12) which in turn overlies a tensile cord (13). The overcord layer supports the tensile cords during molding thereby stabilizing a cordline centerline position with respect to a rib apex. This construction significantly reduces a distance from a tensile cord centerline to a rib apex and rib/pulley interface in a multi-ribbed belt, thereby significantly increasing belt life.
Cette invention comporte une courroie à fils retors qui recouvre des gaines de traction. Une couche élastomère (10) recouvre une gaine tubulaire (11) qui recouvre encore un autre couche élastomère (12), laquelle à son tour, recouvre une gaine de traction (13). La couche de gaine tubulaire supporte les gaines de traction lors du moulage, ce qui stabilise une position de ligne centrale, de ligne de gaine par rapport à un sommet de cannelure. Cet agencement réduit beaucoup la distance d'une ligne centrale de gaine de traction à un sommet de cannelure et à l'interface cannelure/poulie d'une courroie à cannelures multiples, ce qui accroît beaucoup la durée de vie de la courroie.
