Voith upgraded and commissioned PM 53 at Holmen Paper's mill in Braviken, Sweden

Nov 12, 2015. /Lesprom Network/. Voith has upgraded and commissioned the paper machine PM 53 at Holmen Paper in Braviken, Sweden. The PM 53 can now produce various paper grades ranging from newsprint to sophisticated SC papers, including the recently developed Holmen UNIQ SC paper. This paper grade in the basis weight range 43 – 50 g/m2 is suitable for magazines, catalogs and advertising supplements, as the company says in the press release received by Lesprom Network. 

As part of the three-week upgrade, Voith replaced the former EcoSoft calenders with a Janus MK 2 calender. The special design of this calender, featuring a 45° incline of the roll stack, meant that the existing Nipco rolls could be reused while achieving a 40% higher line load. The MasterReel reel winder was relocated for reasons of space and fitted with a LunaReel rubber roll cover, a minor adjustment that was necessary to be able to produce the higher-quality paper grades.

Holmen Paper's Production Manager Jenny Melander said: “The paper was already of a very good quality directly after startup.” The rebuild allows Holmen Paper to enhance its flexibility, because the PM 53 can switch the calender between single, double or multi-nip operating modes at any time without interrupting production, enabling it to produce paper qualities ranging from matt to glossy and from low to high density.

Holmen Paper is part of the Swedish Holmen Group and a major manufacturer of graphic papers. At mills in Braviken and Hallsta in Sweden and Madrid, Spain, it produces high-quality papers for newspapers, magazines, catalogs, advertising supplements and books.

Voith Paper is a division of the Voith Group and the leading partner to and pioneer in the paper industry.
