摘要: What is described is a twin screw extruder having two extruder screws (10, 34), each extruder screw (10) having a cylindrical core (12) and at least one web (14) running helically over the periphery of the outer cylinder face of the core (12), the surface of the web (14) comprising a peripheral side (18) and two flanks (22, 24), and a channel (30) being formed between adjacent web windings. The flanks (22, 24) of the web (14) have a waved progression in the peripheral direction.
