GREEN TIRE EVOLUTION FOR HIGH SPEED UNIFORMITY

摘要

A method for controlling uniformity in tire manufacturing includes the steps of measuring the radial runout of an uncured tire carcass, modeling the radial force variation contribution of the carcass from the radial runout measurement, measuring the thickness of the tire tread, modeling the mass imbalance of the tread from the tread thickness measurement, forming a green tire by loading the tread onto the carcass at an angle whereby the radial force variation contribution of the carcass is opposed to the tread mass imbalance determined from the tread mass imbalance model, and placing the green tire in a curing press at an angle which minimizes the radial force variation or mass imbalance of the green tire.
