Abstract
The method for manufacturing rubber mixtures includes the steps of plasticizing batchwise rubber in a first inner kneader to produce a batch of plasticized rubber and transporting the batch of plasticized rubber, while still hot, into a second inner kneader. In the second kneader nonreactive additives are mixed into the batch of plasticized rubber.
