Method and apparatus for determining a thickness distribution system of a doubly flattened film web, method for adjusting the film thickness profile of a doubled flattened film web, use of a method of adjusting a film thickness profile, and blown film equipment for producing a doubly flattened film web

摘要

The invention relates to a method for determining a thickness distribution system of a double-flattened film web produced in the blown film process by means of a blown film plant with a reversing turn-off with a sensor for film profile thickness measurement, which is used in front of the winder Blasfolienanlage.Ein another aspect of the invention relates to a method for adjusting the film thickness profile a film web, wherein the film thickness profile is measured and adapted inline. Further aspects of the invention relate to a method and an apparatus for producing a film web.
