Edge guiding of the packaging film

The film on the packaging machine must be guided so the unwinding process runs correctly. To this end, the edges of the film sheet are taught in and the position information is used with the help of the MLG-2 WebChecker measuring automation light grid. The MLG-2 WebChecker detects contamination, color changes, or tears in the film and thus offers inline quality control and sheet width measurement.
