Abstract: A process and a system are provided for controlling an addition of water to a rubber mixture during a mixing cycle in which the mixture is transported as a continuous sheet. The process includes obtaining data for the mixture, including a predetermined water flow rate, a predetermined air flow rate, and a target temperature and a target water content for the mixture; adding water to the continuous sheet during the mixing cycle; detecting an amount of water added at an elapsed time during the mixing cycle; determining, using a detection result, a predicted temperature and a predicted water content for the mixture at an end of the mixing cycle; comparing the target temperature with the predicted temperature, and the target water content with the predicted water content; and, before a next mixing cycle, adjusting an actual water flow rate when a comparison result indicates non-equivalence.

Abstract: In one or more rubber mixtures for vehicle tires, production processes and systems are provided for control of water content in a rubber mixture as a function of controlling temperature and water flow rate.
