Abstract
The invention relates to a single screw extruder comprising a grooved infeed system a cylinder and an extruder screw rotatably supported in the cylinder. The extruder screw has a softening zone (10) a main plasticizing zone (14) and a post plasticizing zone and is at least double threaded (18 20) in the area of the main plasticizing zone (14). According to the invention in order to provide such a single screw extruder that enables improved melting effect and also increased throughput reduced melting temperature and improved pressure build up capability the cylinder at least partially has at least one groove extending substantially in the longitudinal direction in the region of the main plasticizing zone (14).
