Virtual sensors and machine learning for digitised Heinzel mill


in Austria using technology provided by Voith. The move follows the rebuilding of the mill’s PM10 production line from recovered magazine paper to corrugated medium last year. “Only by consistently making the most of the possibilities and opportunities of digitalization will we be able to survive in the narrowing market in future too,” said Dr Thomas Welt, chief executive at Heinzel, which currently has capacity for making 800,000 tons a year at Laakirchen. The components of the project use the latest technologies which will be used in real operating

conditions. Meeting the quality targets as cost-effectively as possible and reducing downtime due to breaks are the key objectives of the project. Voith Paper’s Dr Jürgen


Abraham is enthusiastic about the cooperation with the Heinzel Group: “Seldom do you meet a customer who is so open to new methods and technologies. The Heinzel Group is not only impressed with our established digital product portfolio, but has also agreed to work on developing new digital products in collaboration with Voith to harness the enormous potential of the fourth industrial revolution.” Through the intelligent use of the existing data, it is anticipated

The digitisation of the Laakirchen mill is a ‘flagship’ project


that the production and value creation of the PM11 and PM10 production lines will increase and become stabilised at a high level. Virtual sensors and model


predictive controls will be combined with cloud-based innovations from the world of machine learning. Jürgen Käser, project manager


at Voith, said: “Our OnEfficiency. Strength application reliably ensures quick success for our customer. With completely new applications, such as the sheet break prevention, we may need to be a little bit more patient. In the end, it is important that each element contributes to the economic success of the project.”


Sixth turnkey tissue line from Toscotec for WEPA group


An Ahead 2.2S tissue line has been ordered for WEPA’s Piechowice mill in Poland from Toscotec. The repeat turnkey project is


expected to be completed in the third quarter of 2021 and follows the installation of an Ahead 2.0S machine that was commissioned in 2017.


It is the sixth tissue machine to be ordered by WEPA in addition to the numerous rebuilds Toscotec completed for the wet end and dry end sections of WEPA’s existing machines. Since 2015 Toscotec machines


have been installed at WEPA mills in Lille (France) and Giershagen and Sachsen (Germany). Recently the Giershagen mill’s PM19 tissue machine achieved a speed of 2,200 m/min, setting a


September/October 2020


equipped with TT NextPress shoe press technology, a third- generation-design TT SYD, gas-fired hoods with several stages of energy recovery, and an in-line shaft puller at the pope reel. The machine is designed for the implementation of digital technology and advanced control systems supplied by Toscotec and Voith.

new world record for continuous running. The latest Ahead 2.2S machine


features a 2,750mm sheet trim width and a design speed of 2,200 m/min. It will produce


more than 40,000 tons per year of premium quality tissue mainly for away-from-home markets, made of either virgin or de-inked pulp (DIP).

Martin Krengel, chief executive of WEPA Group said, “As in the past, we have great confidence in Toscotec and are convinced that we have the right partner with the latest technology on our side for this project. We continue to trust Toscotec for their commitment to our efficiency and product quality, their operational flexibility and their ability to fully meet our demands.”
