Method and device for processing plastic. According to the method, the plastic raw material is fed to the feed zone of a single- screw extruder (1), from the feed zone it is transferred to a compression zone, in which it is melted to form a molten plastic mass, after which the molten plastic mass is led through a dosing zone to a tool, which a plastic product is formed. In the feed zone, is a grooved portion of the shaft (4) and an at least generally considered cylindrical feed sleeve ( 9 ), in which there are guides, which is moved parallel to its longitudinal axis and/or is rotated around its own longitudinal axis during the regulation of the process, when the plastic raw material is being fed to the extruder, so that an even raw-material flow is created. |
