Abstract
A method of manufacturing a rubber mixture includes the step of mixing at a first temperature in a batchwise operation a base mixture of rubber and non-reactive additives in a ram mixer. In a subsequent step the base mixture is removed from the ram mixer and formed to a strand. The strand is cooled to a temperature at which the strand is still warm. The warm strand is then fed to a ramless mixer and reactive additives are added. In a batchwise operation the base mixture and the reactive additives are mixed at a second temperature that is lower than the first temperature in order to form a finished rubber mixture. Preferably, cooling and feeding of the strand are performed simultaneously.
