ABSTRACT:
Apparatus for extruding plastic and/or rubber material has a screw extruder, which plasticizes the material and delivers it to a gear pump which develops sufficient pressure for extrusion of the material through an extrusion head. The apparatus is characterized by the fact that the axes of gears of the gear pump and the axis of the screw of the extruder are parallel to one another. The housing of the gear pump has a side opening into which a cylindrical bushing and the screw of the extruder extend so that the material is delivered by the extruder directly to the gear pump as a non-oriented plasticized mass. The extrusion head may be a transverse extrusion head with an axis parallel to the axes of the gear wheels of the gear pump and the axis of the screw of the extruder. A second like extrusion apparatus including a screw extruder and a gear pump may be connected to an opposite side of the extrusion head.
