대표청구항 ▼

1. An extrusion head configured for at least one extruder, the extrusion head comprising: a flow channel;a finishing die; andat least two head parts including at least one swivellable head part that is swivellable about a respective joint and is attached to an additional extruder such that the additional extruder is swivellable together with the at least one swivellable head part that supports the additional extruder, the at least one swivellable head part having an opening disposed therein that is in operative communication with the flow channel, wherein the opening is cylindrical and configured to at least partially accommodate a screw shaft of the additional extruder. 2. The extrusion head as recited in claim 1, further comprising an overlapping piece disposed between the finishing die and the flow channel, wherein the opening is in operative communication with the overlapping piece. 3. The extrusion head as recited in claim 1, further comprising an additional flow channel disposed inside of the flow channel, wherein the opening communicates with the additional flow channel. 4. The extrusion head as recited in claim 1, further comprising a cylinder sleeve disposed in the opening so as to at least partially accommodate the screw shaft. 5. The extrusion head as recited in claim 4, wherein the cylinder sleeve is a reducing sleeve. 6. The extrusion head as recited in claim 3, wherein the opening and the additional flow channel form an acute angle. 7. The extrusion head as recited in claim 1, wherein the opening is disposed parallel to a front of the extrusion head. 8. The extrusion head as recited in claim 1, wherein the opening is disposed parallel to one of the at least two head parts. 9. The extrusion head as recited in claim 1, further comprising a closing device configured to close the opening at one of the flow channel and an overlapping piece. 10. An extrusion device comprising: at least one extruder;an extrusion head including a flow channel, a finishing die and at least two head parts including at least one swivellable head part that is swivellable about a respective joint and is attached to an additional extruder such that the additional extruder is swivellable together with the at least one swivellable head part that supports the additional extruder, the at least one swivellable head part having an opening disposed therein that is in operative communication with the flow channel, wherein the opening is cylindrical and configured to at least partially accommodate a screw shaft of the additional extruder. 11. The extrusion device as recited in claim 10, wherein the extrusion head includes an overlapping piece disposed between the finishing die and the flow channel, wherein the opening is in operative communication with the overlapping piece. 12. The extrusion device as recited in claim 10, wherein the extrusion head includes an additional flow channel, wherein the opening communicates with the additional flow channel disposed inside of the flow channel. 13. The extrusion device as recited in claim 10, wherein the extrusion head includes a cylinder sleeve disposed in the opening so as to at least partially accommodate the screw shaft. 14. The extrusion device as recited in claim 13, wherein the cylinder sleeve is a reducing sleeve. 15. The extrusion device as recited in claim 12, wherein the opening and the additional flow channel form an acute angle. 16. The extrusion device as recited in claim 10, wherein the opening is disposed parallel to a front of the extrusion head. 17. The extrusion device as recited in claim 10, wherein the opening is disposed parallel to one of the at least two head parts. 18. The extrusion device as recited in claim 10, wherein the extrusion head includes a closing device configured to close the opening at one of the flow channel and an overlapping piece.
