An apparatus for monitoring a thickness of a film in motion. The apparatus comprises a roller for receiving and supporting the film in motion, the roller being adapted to rotate about an axis of rotation. The apparatus also comprises a position detector for detecting when the roller is in a specific angular position as the roiler rotates about the axis of rotation. The apparatus further comprises a measurement unit aligned with a specific portion of the roller and coupled to the position detector. The measurement unit is responsive to a detection of the roller being in the specific angular position to measure the thickness of the film.
L~invention concerne un appareil de mesure de l~épaisseur d~un film en mouvement. L~appareil comprend un rouleau de réception et de soutien du film en mouvement, le rouleau étant conçu pour tourner autour d~un axe de rotation. L~appareil comprend également un détecteur de position servant à détecter lorsque le rouleau atteint une position angulaire particulière alors qu~il tourne autour de l~axe de rotation. L~appareil comprend en outre un module de mesure aligné sur une partie particulière du rouleau et couplé au détecteur de position. Le module de mesure mesure l~épaisseur du film suite à la détection de la position angulaire particulière du rouleau.
