Extruder for polymeric materials |
| abstract |
The invention relates to an extruder (1) for polymeric materials which comprises an external cylindrical envelope (2) and one single screw (3). The screw (3) is hollow and is provided on its inner surface with helical ribs or internal threads (6); further, it contains a fixed cylindrical body (7). In this way, besides the flow chambers (5) formed between the inner surface of the external cylindrical envelope (2) and the outer surface of the hollow screw (3), an internal flow chamber (8) is obtained between the inner surface of the hollow screw (3) and the outer surface of the fixed cylindrical body (7). |
