For a measurement of the profile during the process therefore relatively simple systems that record only 2 D coordinates are sufficient. If the position of the last pair of rollers is taken to ensure that the profile is tangential to the system, even only a 1-D measurement of the exiting profile is sufficient to detect the entire contour.
