Abstract
A method and system of manufacturing reinforcement materials for rubber products, particularly tires. The method comprises the steps of twisting two or more yarns together to form a cable, and directly after twisting, applying and curing an adhering agent to the cable to form a treated cord. The steps of twisting the yarns and applying and curing the adhering agent are performed on one machine without intermediate take-up. The invention is also directed to a system for producing treated cord, the system comprising a one-machine twist and treat unit.
