In the field of tire production, systems and methods make it possible to selectively carry out monopassage and multipassage rubber production sequences in a common rubber production facility. A tire is formed according to the methods described.

System and method for producing rubber mixtures for tires

System and method for producing rubber mixture for tires

In the field of tire production, systems and methods utilize a feed belt () for directing a rubber mixture from an initial mixing installation () toward at least one of two mixing and cooling installations ('). It is possible to selectively carry out monopassage and multipassage rubber production sequences in a common rubber production facility. A tire is formed according to the methods described.

A system and a method are provided for producing rubber mixtures. The system includes installations for performing a monopassage process and a multipassage process to produce a rubber mixture, and a transport system that transports the rubber mixture to one or more of the installations according to a selected recipe. The installations include a mixing and cooling installation that performs a mixing and cooling procedure in which the rubber mixture is formed into a sheet, the sheet is sprayed with water using at least one nozzle provided with water at a predetermined water flow rate and air at a predetermined air pressure, and evaporated water from the spraying of the sheet is evacuated at a predetermined air flow rate. The mixing and cooling procedure causes the rubber mixture of the sheet to reach target temperature and water-content values before a complementary mixing procedure is performed.
