With FormMax, PressMax, and DryMax, Voith, Germany, achieves a higher level of performance for the paper machine by using the optimum combination of products in the paper production process, the company reports. In the former, press, and dryer sections, Voith products combine perfectly with one another as AdvancedPRODUCTS to lower operating costs, increase productivity, improve quality, and provide a safer workplace for operators.

The Green Bay Packaging mill team in Wisconsin, USA, has found that the FormMax approach has realized all of these goals in its forming section. 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. DuoCleaner Excell (photo right) is an efficient cleaning system for consistent and uniform cleaning of the surface and structure of forming and press fabrics.

 

 

 

 

 

This FormMax solution includes the DuoShake (photo left) to optimize fiber orientation through high-frequency shaking of the breast roll and to achieve good formation and a low tensile strength ratio. The result is good formation with all paper grades and a low tensile strength ratio

In addition, the DuoCleaner Excell traversing cleaning system on both wires is significantly more effective than high-pressure showers. It 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.
