Improve your papermaking line with rebuilds
Get ready for a change!
In today’s business environment, with intense global competition and digital media boom, many mills are struggling for survival. Mills are looking for new ways to remove production bottlenecks, reduce production costs, improve operating safety or transform an existing grade that is suffering from drastic decline in demand.
Valmet has right tools, experience and expertise for variety of paper machine rebuild opportunities. When planning an upgrade or improvement of a paper machine, it always starts with setting the targets. Studies and audits are one way to analyze your machine to find the most profitable upgrade opportunities. Here are a few examples of the reasons to rebuild a paper machine - read more about the opportunities:
- Paper machine grade conversions
- Production increases
- Production cost decreases by improving material efficiency
- Quality improvements
- Energy efficiency improvements
- Machine relocations
- Smaller process improvements

A reliable basis for successful business decisions
“Carrying out pilot trials means you get a real piece of paper in your hand, giving you much more confidence that you’re making the right decisions”, says Manfred Tiefengruber, Paper Production Manager at Sappi’s Gratkorn mill.
“PM 3 is almost like a new machine now; a combination of brand new technology and good, well maintained trusted technology”, says Stora Enso's Jukka Lyyra after successful paper to packaging conversion rebuild.
Sappi Alfeld Mill in Germany recently took on an ambitious project to convert its one remaining graphic paper machine - PM 2 - into what is probably the largest, most innovative, automated and versatile speciality paper machine on the planet, with a capacity of 135,000 tonnes/yr.
"The formation improvement has yielded additional cost savings exceeding the project goal targets. The improved quality level has improved the mill’s flexibility to move higher quality grades to PM 3 that was not possible before the former upgrade.” tells the crew at PM3.
When a papermaking line is rebuilt into a boardmaking line, the rebuild task is very seldom a simple and straightforward project. This was the case also when the papermaking line at Blue Paper was converted to turn out liner and fluting from recycled waste paper.
“We have honestly never looked back or wished we had installed two winders instead of one. The advantages of a single winder, including lower capital investment, simplified material flow, handling of parent rolls and spools, and manpower savings, give us very clear benefits. We have been able to run over 2,300 tonnes per day on the OptiWin Pro without any problem.
The new innovatiove OptiFlo layering headbox at Dongil Wolsan PM1 enables feeding starch between the layers. This increases ignificantly the strenght properties of the end product while providing cost savings as 30% less starch is needed.
