ParAlign Roll Alignment Services from the innovators of inertial alignment.
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.
Frequently Asked Questions
What is Geometric Measurement?
Geometric measure theory (GMT) studies the geometric properties of sets through measure theory. It covers inclination, straightness, level, and flatness.
What are the Benefits of Using a Geometric Tool?
Geometric tools measure surface flatness, foundation levelness, straightness and parallelism, machine geometrics, and shaft plumbness.
Modern systems use laser technology, enabling faster and more efficient measurements of flatness, level, and perpendicularity.
The Benefits of Geometric Tools
Geometric tools, such as laser shaft alignment systems, allow users to take critical measurements, including machine geometrics, shaft plumbness, surface flatness, foundation levelness, straightness, and parallelism.
What Geometric Tools Can Help with Geometric Measurement?
Tools range from simple straightedges and squares to sensors, laser alignment tools, and inclinometers for angular deviation measurement.
Why Surface Flatness and Level are Critical to Laser Shaft Alignment?
Flatness and level are essential to shaft alignment because when a machine is not flat or level, it can cause shaft misalignment.
What Tools are Used When Making a Geometric Measurement?
Many tools are used, from straightedges and squares to precision laser shaft alignment tools.
What our clients say?
“The difference in the calendered part quality was noticeable immediately upon production startup after their work was complete, and the return on investment has already paid for itself in saving waste material…. The speed and precision of their service is second to none.”

What our clients say?
“During the realignment of a large gravure printing press, the entire machine was measured with PARALIGN by PRUFTECHNIK and corrections made on the basis of the offset detected. Then the machine was measured again to confirm good alignment.”
“PARALIGN is very fast and easier to use than optical measuring devices. Four times more cylinders can be measured with PARALIGN than using traditional optical measuring devices.”
