At the beginning of the drying section where the paper web has low strength there are various forces acting on the web, especially in the web release zone. This can lead to an unstable web run, creases, widening and edge problems following sheet breaks. ANDRITZ has created a concept with the PrimeRun Evo that supports trouble-free operation, even at high machine speeds. It does so by gradually reducing the vacuum from the opening nip. Not only does this improve web control, it also reduces energy consumption by up to 50% compared to classic runnability concepts.
