New tissue forming fabrics - Increased quality and better running times.

ANDRITZ Fabrics and Rolls has developed a new forming fabric portfolio with plain weave paper side structure and improved dimensional stability with the lowest caliper in the tissue market. With anticipation, the latest technology called QSB (Quattro Support Binder) can now be applied to this new tissue product line. The patented QSB forming fabric design allows producers to improve tissue product quality and machine performance. It has already been tested successfully at the new ANDRITZ Tissue Innovation and Application Center (TIAC) in Graz, Austria.

UP TO 15% BETTER RUNNING TIMES ON THE MACHINE

The patented new tissue design, with its increased number of binding points, offers improved cross-dimensional fabric stability compared to conventional forming fabric designs. The result is reduced internal fabric wear and allows up to 15% longer running times on the machine. The improved co-planarity and fabric stability lead to a significantly improved resistance to high pressure shower damage. New monofilament material compositions and the re-engineered top fabric design reduce fabric wear and enhance energy-saving potentials.

Meanwhile, ANDRITZ QSB designs are operating successfully in the graphic and packaging paper industries, with numerous installations providing added value to different customer processes. With the new plain weave structure, ANDRITZ Fabrics and Rolls has now complemented its market leading product series for tissue machine applications.

Fabric calipers between 0.55 mm and 0.69 mm enable enhanced fabric surface characteristics with defined dewatering channels for better formation and an effective dewatering process during operation. Machine cleanliness is greatly improved with the application of thinner fabric calipers.

ANDRITZ Fabrics and Rolls tissue product line including the patented QSB technology is available in 2:1 and 3:2 weft ratios for all tissue products and former designs.

SUMMARY

With the patented ANDRITZ QSB forming fabric design, both the tissue product quality and the machine performance can be improved.

PROVEN FEATURES:

High dewatering capabilities (air permeability and low fabric calipers)
Improved tissue quality (FSI >165)
Clean run and no water spray at high tissue machine speeds
Improved cross-dimensional fabric stability for consistent machine operating conditions during the entire running cycle (6 months)

Laakirchen: „ANDRITZ was the right choice“

On October 28, 2017, Laakirchen Papier AG in Austria celebrated production of its first containerboard reel: a milestone in an ambitious rebuild project that was of great strategic importance for the papermaker and for the main supplier – ANDRITZ. At the beginning of January 2019, more than one year later, PM 10 was running with basis weights of around 100 g/m2 at a speed of 1,300 to 1,330 m/min. CEO Thomas Welt comments, “We have achieved the goals set for speed development.”

Holmen Hallsta: It’s all about customer satisfaction

When integrated Swedish mill Holmen Paper Hallsta wanted to further enhance its book paper production process, it called on ANDRITZ to carry out a rather unique project of utilizing two second-hand twin wire presses, and an existing, pre-used screw press to increase capacity and improve pulp quality for its PM 12.
