Detection of curved edges after cutting

Films may have curvatures and deformations after longitudinal cutting. In order to detect these deviations reliably, laser profile sensors from Micro-Epsilon are used. Laser scanners measure the profile of the film on the edge in order to determine the length profile. Due to their extremely high resolution and insensitivity to reflecting surfaces, these sensors provide stable measurement results. Signal processing and evaluation are directly performed in the scanCONTROL SMART sensor which is why no external controller or PC is required. As the sensors are extremely compact, they can also be integrated into restricted installation spaces.
