Rolls that are well aligned – i.e. parallel to each other – improve product quality and increase productivity through higher machine availability and production output.

Parallelism of rolls is even more important when machines are running at high speeds and/or when rolls are in close proximity.

PARALIGN is the fastest roll measurement method in the market.

With a quick setup procedure and fast measuring process, entire machines can be measured during short maintenance outages. PARALIGN results are instantaneously displayed which allows necessary corrections to be made quickly and adjusted rolls to be re-measured immediately.

PARALIGN can even measure rolls in enclosed sections or across multiple levels of a machine because, unlike optical measurement systems, it does not require any line of sight. In addition, no baseline is needed for the measurement since the offset is defined in relation to a reference roll.

PARALIGN consists of three ring laser gyroscopes, enabling it to take measurements in three-dimensional space. (Roll, Pitch, and Yaw). No line of sight is required. This helps us achieve very reproducible results.

To perform a measurement, the PARALIGN device is placed on the roll and swept a minimum of 20 degrees about the roll’s circumference. During 30-second measuring window, the points are evaluated for acceptable values to ensure accurate results. The measurement results are instantly transmitted wirelessly to a laptop.

Yes. Rolls should be parallel to ensure that the product being created is uniform and of good quality.

Parallelism of rolls is even more important when machines are running at very high speeds and when the rolls are very close to each other.

It is critical to ensure roll parallelism to reduce uneven bearing stresses, tracking, web breaks, uneven coating, wrinkling, delamination, warping, roller surface wear, tension irregularities, etc.

Proper roller alignment minimizes waste, downtime and maintenance costs.

The PARALIGN can be positioned anywhere along the circumference of the roll so as long as there is 20 degrees of 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 smallest roll can be 43cm (17 inches) in length and 8mm (0.315 inches) in diameter.

The graphical readout is displayed in the corresponding PARALIGN software as soon as each roll is measured. A full report with initial and final alignment results is given to the customer upon completion of the service.

The PARALIGN does not decrease in accuracy based on location, elevation, or proximity.

We offer the PARALIGN Service for roll alignment as a service to our clients. PRUFTECHNIK does not sell PARALIGN at this time.

The PARALIGN system does not require a visual line of sight to gather alignment data. The PARALIGN system becomes an essential tool when measuring enclosed oven rolls, tower rolls, or rolls located across multiple floors/levels. However, the software has the ability to incorporate optical data from a baseline if required.
