<p>The system has an extrusion head (10) i.e. hose head, and an extruder housing (11) between which an articulated connection is provided with two joints (13, 15, 16). The head is connected with a front region of the housing over an articulated arm system. The extruder housing comprises articulated arms (14, 17), where one of the articulated arms is connected with the other articulated arm and attached at an end of the head. The articulated arms are adapted such that strokes are added or subtracted based on a rotational position, and articulation axes of the arms are run parallel to each other.</p> |
