<p>The invention relates to a device for the extrusion of thermoplastic synthetic material featuring an extruder screw (2) which is mounted on a housing (1) comprising a plasticizing section (P) at the inlet side, a degassing section which is mounted upstream on a discharge section (A) and a conveying outlet (3) running in the opposite direction which is located between the plasticizing section (P) and the degassing section (E), with a flow channel (5) that contains a melt filter (4) which is bridged over by at least one of the conveying outlets (3) in the opposite direction. In order to create favorable production conditions, it is suggested that the extruder screw (2) forms a similar conveying outlet (7) running in the same direction between the conveying outlet (3) in the opposite direction and the downstream port (6) of the flow channel (5), and that the housing (1) has at least one degassing vent (8) at the transition area of the conveying outlet (3) running in the opposite direction and the conveying outlet (7) running in the same direction.</p> |
