This also applies to the success on PM 4. For more than three years Voith SkyTop doctor blades have been used on the center press roll of the paper machine in Bruck an der Mur where wood-containing graphic paper is produced. The application of SkyTop on the center roll significantly helps in achieving improved paper machine performance. Doctor contamination was greatly reduced and the running time was considerably extended.
Moreover SkyTop achieves a constant roughness of the roll surface affecting the paper quality in a positive way. "With SkyTop blades we succeed in maintaining the roughness of the center ceramic roll for the entire roll cover width on the designated high level over several years", explains Gernot Christöfl, Assistant Line Manager PM 4. The performances on the racetrack and the increase in doctor blade efficiency together demonstrate the close and trustful cooperation between Norske Skog and Voith Paper.
Norske Skog Bruck PM 4 manufactures 57 to 90 g/m² wood-containing graphic paper at machine speeds of up to 1500 m/min.
