WeValue series
Forming fabrics for specialty paper. High-tech ensures 100% reproducibility.
The challenge
Paper mills for specialty papers depend on controlled drainage, long lifetime, high dry content, running stability, clean run, prevention of fiber compression, uniform formation, effective filler/fines retention, as well as decreasing energy costs.
The solution
Filters, silk, decorative, or security papers: our forming fabrics are individually tailored for the most challenging applications with the highest quality demands. Our objective is to guarantee constant paper characteristics through perfect reproduction at a consistently high quality. Our key to success: The highest in precision and uniformity in every manufacturing step – starting with intelligent product design to the highest precision in weaving and on to final finishing. Control and strict monitoring of every individual manufacturing parameter are crucial. Process steps with especially high control potential are identified and constantly refined, enabling us to master the ultimate challenge: perfect reproduction of specialty papers to meet high demands.
We are able to perfect a complex production process that allows us to precisely balance the various parameters. Our coordinated thermofixing routines control the interaction of exactly defined temperature curves, the continuous build-up of traction, and the optimum time input – at an absolutely constant run speed. Our technologically balanced product designs offer tailored solutions for every type of paper machine and every grade of paper – for the highest demands and perfectly reproducible quality.
They ensure:
- homogeneous paper-side topography
- dimensional stability
- fixing of the weave architecture
