Paper Technology Journal 19 - Voith

Within the framework of the Process Line
Package, however, Voith not only took responsibility
for its own scope of supply.
Rather the sub-suppliers were also incorporated
into the overall planning and project
processing performed by Voith.
The Process Line Package gave LEIPA
solid advantages: Voith was responsible
for the coordination of all sub-suppliers.
In this way, the interfaces with suppliers
that arose during planning, delivery,
installation, start-up and optimization of
the production line, were minimized. The
convincing result is a very fast and costeffective
implementation of the project.
The smooth handling of the project with
the Process Line Package made a major
contribution to the fact that the production
line was able to go into operation as
early as 4 weeks ahead of the contractually
agreed start-up date.

Systematically to success –
LWC from 100% recovered paper
LEIPA and Voith together faced a major
technological challenge with this project.
For the first time, it was intended to produce
first-class LWC paper from up to
100% recovered fibres with a production
line of this dimension. To translate this
idea into reality, LEIPA and Voith entered
into a system partnership.
Within the framework of this system partnership,
comprehensive trials were conducted
on the Voith pilot machines and
work was carried out on product development
in intensive cooperation.
The system partnership forms the basis
for the further successful development of
the project and includes the following
core elements:

● Joint planning and conduct of trials
● Optimization of the machine even after
start-up to achieve a steep start-up
curve
● Support by Voith for technological
objectives and further developments
beyond the agreement.
To achieve a good start-up curve, Voith
also carried out Performance Management
for the new production line. For
this, the experience gained from the
start-up and operation of comparable machines
was evaluated for the LEIPA project
in order to determine the optimal
start-up parameters for PM 4 in advance.
Common expertise of LEIPA and Voith
paired with innovative Voith technology
ultimately led to the success: a state-ofthe-art
LWC production line that sets new
standards in the LWC paper marketplace.
The LWC paper produced by LEIPA on
the basis of 100% recovered paper meets
the same quality demands as LWC paper
based on virgin stock. Consequently,
PM 4 produces an economical and highquality,
competitive product. Laboratory
analyses as well as the extremely satisfied
customers of LEIPA today confirm
the excellent quality of the LWC paper
produced on PM 4.
