Abstract (en)
[origin: WO2017198262A1] The invention relates to a method for the open-loop and closed-loop control of pipe extrusion systems, taking into consideration measurement data of a produced pipe (4), wherein the excess of a molten pipe (4') passing out of a ring gap (11) of an extruder unit (1) runs into a subsequent calibration device (6). The object of the invention is to provide a method of this type which works with measurement values that guarantee an optimal operation of the extrusion system, even in the event of a change in dimension. The object is achieved in that the diameter, the wall thickness, possible shape deviations and the slackness of the molten pipe (4') is determined exactly at multiple points between the extrusion tool (3) and the calibration device (6), and these measurement values or the data calculated therefrom are used for the open-loop and closed-loop control of the extrusion system.
