Koehler Paper is also relying on leading Voith technologies in the second rebuild stage of paper machine 5. A new NipcoFlex shoe press in the existing press section ensures more sustainable production. The technologically leading solution from Voith also increases production capacity.

Successful cooperation between Koehler and Voith

After a successful first rebuild stage of paper machine 5 in Oberkirch – installing the Voith SpeedSizer film press and contactless qDryProCompact high-performance drying system – Koehler Paper has confirmed its confidence in Voith. Hartmut Felsch, plant manager at Koehler, Oberkirch, Germany: “In Voith, we have found a strong and reliable partner with the highest quality standards for all areas of paper production.”

Thorsten Heidt, Senior Sales Manager at Voith, also confirms: “We have a long-standing, successful business relationship with Koehler. Koehler recently achieved a world speed record with the new PM 8 line at the Kehl location, thanks to our successful cooperation and continuous optimization. We are very pleased that Koehler has again opted for our leading technologies and that our solution is convinced in all points.”

More sustainability and production capacity through new technologies

Koehler has selected the full-line supplier to deliver the second modernization stage, focusing on the much-proven NipcoFlex shoe press. The aim is to achieve an optimal production result. With the installation of the NipcoFlex shoe press in the existing press section, the dry content after the press is significantly increased. As a result, large amounts of steam can be saved in the dryer section for drying the paper web.

The rebuild thus helps save energy and reduce CO2 emissions in the plant. In addition, the higher dry content increases line speed and production capacity. At the same time, work safety and operability are improved when changing the felt with the aid of the cantilever framing for the pick-up felt. 

The rebuild is a tailor-made solution and addresses the limited space available, especially on the drive side of the machine. As part of the rebuild, the transfer process from the press to the dryer section is optimized, and a draw reduction is achieved to increase efficiency significantly. 

The press roll uses a TerraSpeed Trend Supreme ceramic coating, which is also utilized on other Koehler Paper machines. This guarantees optimized sheet release with long running times and a high level of cleanliness. The order is complemented by the proven QualiFlex shoe press sleeves and a start-up set for all press felts. 

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital 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.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
