Production speeds in the paper, printing, converting and steel industry are nowadays higher than ever before. Misalignment of rolls is root cause for creases and sheet breaks, for example in paper production. With PARALIGN service, the parallelism of rolls can be determined faster and more precise than with traditional methods. In PARALIGN for the first time inertial measurement technology is in use, which allows for use of the measurement device also in enhoused areas, without loss of accuracy and time.
