Double layer detection when splicing

Highly productive packaging processes require a continuous supply of film. Flying roll changes with the machine running help here, as the films are spliced automatically within fractions of a second at a certain point. If a double layer is produced at the splicing point, this must be identified so it can be rejected later. The UD18 ultrasonic sensor reliably detects double layers and identifies the position being sought quickly and accurately.
