Voith Paper know-how
For decades, Voith has built up and
expanded its knowledge and capabilities
in all areas of the paper production
chain.
Beginning with the paper machine,
competence was extended to all
process-influencing sections: automation,
fabrics, roll covers, ventilation
systems, chemicals, water treatment
and energy generation from waste.
The One Platform Concept unites all
these competences as one solution.

• Newsprint = NP
• Magazine Paper (SC/LWC) = MP
• Office Paper = OP
• Fine Paper (wood-free coated) = FP
There are three sizes respectively:
200, 400 and 600
Using these categories, the machine
concept, the machine width and the
design speed are determined. Of
course, the individual modules can be
adapted to special customer wishes.
The economical optimum is in each
case at the upper limit of a size. The
nominal capacity of a production line
is also determined by the basis weight
to be produced. Depending on basis
weight (42, 45 or 48.8 g/m²) and overall
efficiency, a NP 400 can thus produce
between 370,000 and 430,000 tons per
year. Experience shows that for some
paper grades not all three sizes are in
demand, but instead initially two sizes
are favored by the market (Fig. 2).

• OP 200 and OP 600

Advantages of the
one Platform Concept
By means of consistent standardization
and optimization of the individual
modules, for each of the sizes Voith
is able to offer an economically optimal
concept that technologically
meets the highest market requirements.
Not only specific investment
costs, but also especially the operational
costs have been optimized for
each of the sizes. Minimal consumption
of long fibers due to closed draw
press sections, minimal steam consumption
due to high dry contents,
low chemical costs due to optimized
process control and minimal water
consumption due to shortening the
circulation loops are examples of
economic advantages for the papermakers.
Added to this is the extensive experience
that Voith has acquired over
the last years with these lines. Thus,
start-up and commissioning times
can be shortened. After a short time,
the production lines are running at
outstanding levels of efficiency and
producing the nominal output.
