ParAlign Roll Alignment Services from the innovators of inertial alignment.
ParAlign is a unique, non-optical measurement method using inertial technology designed to measure the parallelism of rolls in production installations in the paper, print, converting, steel industries, and web-handling/roll to roll transfer processes.
Misalignment in rolling machinery can lead to wasted material, inconsistent or low-quality products, and excess machine wear. Properly aligned rolls perform better, create more consistent products, and reduce wear and tear on machinery.
Three-ring laser gyroscopes enable the ParAlign to take measurements in three-dimensional space (roll, pitch, and yaw). No line of sight is required, which creates consistent, reproducible results.
Types of Services
The Pruftechnik Services team offers two types of roll alignment utilizing the ParAlign gyroscopic technology:
the ParAlign Service and the Peak RGA Service.
The ParAlign Service is performed with the ParAlign alone. When performing the service, the device is placed on a roll and swept a minimum of 20 degrees about the roll's circumference. The ParAlign can be positioned anywhere along the circumference of the roll as long as there is enough clearance to complete a proper measurement using the SWEEP method. This flexibility allows for rolls to be measured on the top, bottom, or sides, depending on which is most accessible.The measurement takes about 30 seconds, and results are instantly transmitted wirelessly to a laptop.
The Peak Roll and Geometrical Alignment (RGA) Service is a total alignment solution combining the ParAlign with laser trackers to align rolls and their surrounding structures in the shortest time possible—while producing accurate results and instant visual reports. No other roll alignment method combines gyroscopic and laser tracker technology.
