Abstract

The measuring of the thickness profiles of plastic films is by applying the presently known methods difficult and the measuring results are not dependable. According to the invention the thickness measuring of the plastic films (1) is performed by using infrared transmission in such a manner, that on the one side of the plastic film is placed a resistance wire (2) reaching over the plastic film, the intensity of the infrared radiation emitted by which is directed by means of the turnable reflecting device (3) to the analyzer (4) placed on the other side of the plastic track. The method is suitable for the on-line thickness profile determination of plastic film manufactured both by the planar as by the fan-tail die extrusion method.
