Voith has carried its extensive competence in paper machines over into the HydroFormer concept and thus makes it possible to produce high-quality nonwovens in this segment too.
In a circuit, a filter system treats the white water from the HydroFormer and AquaJet and returns it to the manufacturing process.
There is, of course, a fair amount of secrecy among hydroformers so the knowledge base is growing, but tends to advance in isolated pockets.
Hydroformers tell the mills they don't know how to make tubing.
Voith supplied a key component, the HydroFormer
. The HydroFormer
concept builds on Voith s long expertise in the pulp and paper industry.
The new production line is the first one on the Chinese market to use the innovative wetlaid spunlacing (WLS) concept of the HydroFormer
and Aquajet technology, developed by Voith Paper and Triitzschler, respectively.
The primary machinery consists of Voith Paper's wet-laying machine, the HydroFormer
, a specially configured Aquajet spunlacing unit, a drum dryer and a winder, the latter being supplied by Truetzschler Nonwovens.
Both the HydroFormer
, Voith Paper's wet laying machine, and Triitzschler Nonwovens' spunlacing unit the AquaJet, are highly productive as well as highly efficient solutions that have proven themselves in dozens of installations all over the world.
With its HydroFormer
, Voith Paper contributes the core component to the cooperation.
This equipment, called the HydroFormer
M Series, uses long fibers and low headbox consistencies in the range of 0.01 to 0.08% to produce good web formation.
