Abstract: An extruder head for producing profiles of rubber and/or plastic mixtures has a stationay main part which has a forward face in which the discharge ends of at least two extruders, rigid with the stationary main part open. The stationary main part has a transverse pivot shaft at one side of the forward face and, at the side opposite the pivot shaft, an abutment which projects forwardly of the forward face. A movable main part is pivoted, with play, on the pivot shaft and is swingable between a closed position in which it overlies the forward face and an open position. An extrusion die unit is disposed between the outboard end of the movable main part and the abutment. Flow channels between the movable main part and the stationary main part lead from the extruders to the extrusion die unit.
