New Voith quality tools benefit papermakers

New OnQuality fiber measurement and control orientation profile

Papermakers benefit from Voith’s new OnQuality fiber orientation measurement and control.

With the newly launched fiber orientation measurement and control of Voith’s OnQuality product family, paper manufacturers can reliably control the fiber orientation angle. The new solution consists of the OnQ fiber orientation sensor, which continuously measures fiber orientation in real time, the OnQ profilmatic fiber orientation control system, and the OnQ modulestep and OnQ modulejet actuators.

“The benefits of the new fiber orientation measurement and control are numerous,” said Marc Stampfer, global product manager QCS scanners and sensors at Voith Paper. “With the new solution from Voith’s quality control system portfolio, papermakers can control the required fiber orientation angle and thus influence and improve the tear length ratio. Due to the homogeneous orientation of the fibers, B quality can therefore be avoided, especially in the edge areas of the paper web.”

“In addition, curl can be reduced and the runnability of the machine and the grade change process improved,” adds Andreas Haux, global product manager QCS Actuator Systems at Voith Paper. “The cost savings achieved with this range up to several million euros per year for a modern packaging paper machine.”

Due to the precise control possibilities, major international packaging paper producers already rely on the application to ensure their product quality.

After a short rebuild and commissioning phase, the investment pays for itself in most cases in less than a year. The integration of the quality control system is applicable for existing plants worldwide and independent of the manufacturer with little effort.

Functional principle of the new automation solution

Voith Fiber orientation control architecture.

The OnQ fiber orientation sensor uses high-resolution macro photography, digital image processing and nanosecond flash illumination to distinguish the individual fibers and their orientation in the moving paper web. Surface measurement is possible on both one and two sides. The OnQ profilmatic CD control system derives suitable set points of the OnQ modulestep actuators from the measured fiber orientation angles, which enable zonal, mechanical profiling of the headbox slice lip using stepper motors. In combination with the OnQ modulejet actuators, the dilution water can also be controlled, thus avoiding undesirable side effects on the basis weight.

OnQuality 4.0

Voith’s OnQuality 4.0 is an intelligent and integrated concept that enables manufacturers to gain control over production processes and product quality. A broad portfolio of scanners and sensors ensures reliable and continuous measurement of various quality parameters. The intuitive apps of the cloud platform OnCumulus provide a wide range of analysis, reporting and visualization functions that are available at any time via different end devices and optimally complement the fiber orientation solution. In addition, the paper technology experts at Voith’s OnPerformance.Lab provide support to further increase the efficiency and productivity of the plants with the help of remote consulting and optimization. 

Automation is a focus of Voith’s new “PAPER IS ON” campaign. The campaign highlights the focus topics of full-line supplier, efficiency, sustainability, cloud solutions and innovation, which impact the digital product portfolio.

2023 promises an interesting ride for print in India

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. While the print and packaging industries have been resilient in the past 33 months since the pandemic lockdown of 25 March 2020, the commercial printing and newspaper industries have yet to recover their pre-Covid trajectory.

The fragmented commercial printing industry faces substantial challenges as does the newspaper industry. While digital short-run printing and the signage industry seem to be recovering a bit faster, ultimately their growth will also be moderated by the progress of the overall economy. On the other hand book printing exports are doing well but they too face several supply-chain and logistics challenges.

The price of publication papers including newsprint has been high in the past year while availability is diminished by several mills shutting down their publication paper and newsprint machines in the past four years. Indian paper mills are also exporting many types of paper and have raised prices for Indian printers. To some extent, this has helped in the recovery of the digital printing industry with its on-demand short-run and low-wastage paradigm.

Ultimately digital print and other digital channels will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future. For instance, there is no alternative to a rise in textbook consumption but this segment will only reach normality in the next financial year beginning on 1 April 2023.

Thus while the new normal is a moving target and many commercial printers look to diversification, we believe that our target audiences may shift and change. Like them, we will also have to adapt with agility to keep up with their business and technical information needs.

Our 2023 media kit is ready, and it is the right time to take stock and reconnect with your potential markets and customers. Print is the glue for the growth of liberal education, new industry, and an emerging economy. We seek your participation in what promises to be an interesting ride.
