Voith completed the rebuild of Holmen Paper’s PM 53 in Braviken, Sweden, from newsprint to magazine papers and successfully commissioned the modified machine. Since the upgrade, Holmen Paper has been producing its newly developed SC paper Holmen UNIQ on the PM 53.
The VariFlex winder from Voith has been developed to be an all-rounder. With two recent installations, it has once again demonstrated its versatility in two paper mills a great distance apart, in Turkey and France. At both locations, the winder was retrofitted in as part of an upgrade. In France, it is used for light to mid-weight corrugating medium and in Turkey for heavy coated board grades.
An upgrade at Papierfabrik Palm’s Eltmann mill in Germany has transformed its deinking plant into a state-of-the-art facility. The rebuild of the stock preparation unit, which took just six days, was carried out by Voith in the month of April. It allowed Palm to substantially improve the efficiency of the facility. In the flotation section alone, electricity consumption per metric ton paper produced fell from 60 to 35 kW hours.
Pulping drums pulp the recovered paper, which plays a valuable role in paper manufacturing and remove coarse contaminants from the pulp. In the course of this process, a minimum of paper fibers and a maximum of contaminants should be discharged. IntensaDrum, a new pulping drum from Voith, has been in use in the paper industry since last year, achieving markedly better results than comparable legacy technologies. IntensaDrum pulping drums are part of Voith’s BlueLine product line.
At Hadera Paper, a DuoFormer D II with a short pre-dewatering section has proved itself over several months with excellent results. The Voith former was installed as part of a rebuild and has noticeably improved the sheet forming with a shorter pre-dewatering zone.
At Mpact Limited’s paper mill in Felixton, South Africa, a VariFlex winder has been installed in only eight days, which is quite remarkable. Only two days after the start of production it was running at its maximum operating speed of 2,500 m/min. The paper manufacturer had thus already achieved a key investment objective with the start of production.
With the rebuild of the Eilenburg PM 1, Stora Enso Sachsen has achieved two advantages and has safeguarded its production for the future, thanks to its new Voith calender, offering better smoothness and thus higher paper quality. In addition, the calender can be upgraded in the
future and expanded to a Janus with 2x3 rolls. Paper of higher quality can thus be produced
as needed in the future, with greater added value.

From Italy to Sweden: Four European paper manufacturers have planned and realized rebuilds on their paper machines in cooperation with Voith. The main goals were increased machine efficiency and runability as well as reductions in raw material consumption.
To achieve them, Voith installed a DuoFormer Base and rebuilt a size press, while also integrating an EdgeSaver module and NipcoFlex presses. And thus the papermakers
could meet their targets: Efficiencies were increased and costs reduced.

The paper manufacturer APP wanted its BM 6 board machine to process 1,100 m/min – more than a
machine for high-quality art board has ever produced. To achieve
this goal, suction forming
boards and a suction roll were
installed, the press section
was supplemented by
new water doctors, and
splash pans and the
entire dryer section was
reconfigured. Everything
was to take eight days
and not an hour longer.
It really couldn’t be
done – really.
