SCA, Sweden, will upgrade the existing Pope reel and purchase a new winder and a new roll transport system for its Munksund Mill in Piteå, Sweden. Voith Paper, Germany, was chosen as the major supplier for these projects. Munksund intends to optimize and automate the entire process from the Pope reel, thus improving both its offering and paper production capability. The 7.1 m wide PM 1 produces kraftliner and white top kraftliner in a basis weight range of 125 to 440 g/m2.

Voith will rebuild the old Pope reel to achieve larger roll diameters and will deliver new reel spools. Parent roll handling and parent roll/reel spool transport systems will be renewed as well. The biggest single unit will be the VariFlex winder with flying splice for parent roll changing and a new type of start-and-end gluing. A pulper and an automatic core cutter are also included in the scope of supply. A transport system will be installed to transport the finished rolls to the existing wrapping equipment.

The VariFlex winder at the Munksund mill will have a maximum operating speed of 2,700 m/min. The SCA Group has had considerable experience with Voith winders in various mills and again decided on a Voith winder after having placed its latest order for Aschaffenburg, Germany, with Voith.

The upgrade of the PM 1 in Munksund will be completed in several stages, beginning this fall. The winder will come on stream in spring 2011, and finally, in fall 2011, the existing Pope reel will be rebuilt.
