In order to improve the printing performance of the paper, the coating and starch are applied to the paper by a glue applicator during coating and sizing. Voith's new SupremeFilm rubber rolls are suitable for VoithSpeed Sizer AT, as well as other difficult film calendering applications.
Ralf Moser, Voith Global Product Manager Finishing Division, explains: "For many years, polyurethane rubber rollers have been a successful high-end solution for the calendering department. We are now taking advantage of this high-quality, tailor-made material for calendering."
SupremeFilm is characterized by extremely uniform and stable film transfer. In addition, with Voith's innovative filler material concept, it maintains its surface roughness throughout its useful life. This ensures ideal glue application when producing high-quality paper. In addition, the polyurethane material is highly abrasion resistant, which results in a longer wear time for the rubber roller and a cross-sectional size of less than two standard deviations.
The Ehingen paper mill in Sappi was one of the first customers to successfully use the new SupremeFilm rubber rolls in film printers.
Dietmar Muser, manager of the paper mill at Sappi Ehingen GmbH, said: "Our goal is to continue to grow and increase our productivity. We need new technology to achieve this. This is also the best we choose to work with Voith to use Voith's newly developed Promising products. We've taken a step forward with very good performance, and this attempt has paid off. SupremeFilm can keep wear and tear within two margins for a very long time. This means we achieve The main goal of producing perfect paper quality. In addition, we also reduced maintenance costs and extended uptime between replacement rollers. "
