Abstract

An extruder (1) head for the manufacture of tubing, in particular tubes made of plastic such as PVC and similar, there is a section of central core partially blown (14) provided with multiple longitudinal grooves with helical flow (15). The said section (14), situated downstream from the central ring (5), which supports the core (2) provided with fixed components in a dial (3), has the task of imposing on the most internal fibres of the flow being extruded a spiral feed movement which favours complete amalgamation of the same with the fibres above and ensures that tubing is produced with external and internal surfaces, which are perfectly smooth.
