Abstract
A method of treating a polyester cord reinforcement for a tire, comprising subjecting the reinforcing material, in a first stage, to a temperature in excess of 227º C, at sufficient tension, for a period of 30 to 70 seconds to stretch them from 2 to 10% of its original length, and then, in a second stage, subjecting the reinforcing material thus treated to a temperature at least five degrees centigrade higher than the temperature of said first stage and said last temperature, in the second stage , leave the reinforcement material under a relaxed tension for 30 to 70 seconds to shrink from 30 to 50% of the amount that has been stretched in the first stage, and then keep the residual stretch present, after the second stage in which is made to shrink the reinforcing material, without substantial change, while the reinforcing material is cooled to substantially room temperature.
