METHOD OF FORMING A POWER TRANSMISSION BELT TENSILE CORD

摘要

A manufacture of an impact-resistant power transmission belt tensile cord and belt using the same. The tensile cords of the invention are caused to have coordinated characteristics of toughness, elongation under load, shrinkage, and shrinkage stress so as to provide absorption of longitudinal and transverse impact shock forces to the belt during high power transmission therethrough, with minimized dimensional changes of the belt over the useful life thereof, permitting the belt to be utilized in multiple parallel drive applications in extremely rigorous environments with minimized maintenance. The tensile cords are adhesively coated, thermally drawn and set multifilament polyester cords.
