Abstract: Process for the manufacture of a rubber composition comprising various constituents, such as base elastomers, reinforcing fillers, additives and a vulcanization system, during which the following stages are carried out: A—using a continuous mixing device, a starting rubber composition comprising the reinforcing fillers and optionally other components, with the exception of the crosslinking system, is produced, the operating parameters for the continuous mixing device being chosen so that: a—the residence time of the elastomer in the mixing chamber is between 20 and 60 seconds, b—the specific energy conferred on the rubber composition is between 2000 joules/gram and 5000 joules/gram, B—at the outlet for the starting rubber composition from the mixing chamber, the temperature of the said starting rubber composition is lowered to a temperature of less than 140° C. in less than 5 minutes.

Abstract: Method for the production of an initial rubber composition, in the course of which the following steps are carried out in succession: A—a rubber matrix, reinforcing fillers, and other components if required, with the exception of the cross-linking system, are introduced into a mixing means of the internal mixer type, comprising a mixing chamber in which there are mounted rotors which are driven in rotation and have radial projections forming a gap (e) between themselves and the vessel, B—said components are mixed in the chamber until a uniform mixture is obtained, care being taken to ensure that the temperature of the mixture remains at or below 170° C., after which C—the rotation speed of the rotors is adjusted so as to bring the rubber composition to a dropping temperature in the range from 180° C. to 240° C.
