In the former, press and dryer sections, the Voith products combine with one another as AdvancedPRODUCTS to lower operating costs, increase productivity, improve quality and provide a safer workplace for operators, it says.
The Green Bay Packaging mill team in Wisconsin has found that the FormMax approach has realized all of these goals in its forming section, noting that the “drainage is more uniform, dry line on the wire is more level, sheet breaks have been halved, chemical cleaning and hazards are significantly reduced, and the paper strength target is achieved using a lower basis weight.”

Voith says the FormMax solution includes the DuoShake to help optimize fiber orientation through high-frequency shaking of the breast roll and to achieve good formation and a low tensile strength ratio. In addition, the DuoCleaner Excell traversing cleaning system on both wires promises to be significantly more effective than high-pressure showers, says Voith, adding that this gives more uniform cleaning of the surface and structure of forming fabrics. The Voith I-Series forming fabric will be installed later this year as part of the continuing optimization program.
