Abstract
In order to check a material web (), in particular a film web, with regard to the correct arrangement of a tear-off strip () extending in the longitudinal direction of the material web (), ultrasonic transmitters are used, specifically an ultrasonic transmitter () on the one hand and an ultrasonic receiver () on the other hand. The sensors are arranged on opposite sides of the material web () in such a way that, if appropriate, focused ultrasonic waves are aimed specifically at the region of the tear-off strip (). If a tear-off strip () is missing, an appropriate signal is generated by the ultrasonic receiver ().
