Film thickness measurement

  Film thickness measuring systems through a scanner, equipped with a capacitive sensor, are divided into:

  • Fixed scanner - FTM 1000: the scanner is mounted in the compression zone under the winder and uses rotation/inversion of the haul-off to scan the film thickness tolerance profile.
  • Rotating scanner - FTM 2000: the scanner measures the thickness profile of the film by moving on a circular guide around the film bubble. The advantage of this system is that it allows more frequent measurements in the various sectors of the bubble. This is particularly useful after a change of production for effective profile control.
