ABSTRACT OF THE DISCLOSURE In an extruder for making blown tubular film, an extrusion nozzle is divided into equally long segments provided with tempera- ture setting elements. The film thickness is measured over the circumference of the film and film sectors of equal cross-sectional area are allocated to the nozzle segments out of which they were extruded. To produce thick film portions, the associated nozzle segments are cooled accordingly and to produce thin portions the associated nozzle segments are heated accordingly.
