Our products

Product category: Web inspection and control systems

Condition Monitoring

Condition monitoring of the roller bearings is the most critical factor in all paper and pulp production processes. Depending on the operating condition and level of diagnostic, diverse evaluation methods are used, from simple analysis of overall values to advanced envelope spectrum analysis.

In the paper machine, usually all measurement locations, but especially the inaccessible ones, such as in the hot dryer section, are monitored with a networked, multi-channel online system. All production-critical secondary components, such as pulp preparation pumps, vacuum pumps and fans, likewise are equipped with online condition monitoring systems. Mobile data collection with portable, high-performance instruments is suitable for all other measurement locations on lower-level components.

Cardan Shaft Alignment

Rollers in the press section, on the calender or in the coating machine are often driven by means of cardan shafts. After servicing or replacing a motor in the press, the alignment of the motor and roller shaft must be checked. Although cardan shafts by definition compensate the parallel offset, the angular misalignment must be within the manufacturer’s tolerance, to prevent premature wear of the universal joints. Unplanned downtime costs valuable production time, in addition to the substantial costs for the loss of the cardan shaft.

Laser-based measurement systems can prevent this. In addition to the alignment of cardan shafts, our systems are also used to measure and optimize the geometry of machines and components, for example:

  • Rotational axis alignment
  • Flatness
  • Straightness.

Roller Paralism

In the paper machine alone the paper passes a web length of hundreds of meters. If parallelism of the rollers is not given, paper can break and tensions due to the uneven web may accumulate in the paper and manifest in the subsequent production steps: at the roll cutting machine, as a result of web breaks in the printing machine or through compromised print quality.

The parallelism of rollers, rolls and cylinders in a paper machine is therefore crucial for the product quality and process assurance. With the unique PARALIGN roll alignment system, several rollers can be aligned with each other to within a few microns in a fraction of the time otherwise needed. Roller measurement with PARALIGN has become a standard process in the wet section of a paper machine and also in the enclosed dryer section.

About us

Company details

Mid-size, global, customer-oriented

PRUFTECHNIK has more than 600 employees working in our business divisions and subsidiaries worldwide. Almost half of our employees work in Research & Development, and the number of university graduates is also very high at ca. 50%.

The PRUFTECHNIK business divisions operate independently and benefit from central services of a higher level holding company. This streamlined organizational structure allows the PRUFTECHNIK group to operate flexibly and efficiently in the world market. The high export share – which has always been an indicator of technically qualified products – has increased due to the development of agencies and subsidiaries on every continent. Today, this share makes up ca. 75% of the total production.

With our international subsidiaries, our employees are most of the time already where they are needed. This global and at the same time local presence allows PRUFTECHNIK to respond optimally to the wants and needs of the customers.
