Abstract
An apparatus for producing rubber mixtures. A ram kneader that operates in a batch process is provided for producing a master batch. A ram-less kneader for producing a final mixture is disposed below the ram kneader. A chute is disposed between the ram kneader and the ram-less kneader for supplying rubber mixture to the ram-less kneader via an inlet thereof. At least portions of the walls of the chute form closure members that are pivotable downwardly to at least partially close off the inlet of the ram-less kneader.
