VariTop winders. Afterwards, the slit rolls
are transported to an automatic weighing
device and labeling unit and finally to the
Twister 2 Line roll wrapping system. The
finished wrapped rolls are then sent with
the help of chain conveyors over a connecting
bridge from the PM building into
the finished goods warehouse.
As part of the Process Line Package,
LEIPA received a production line, that not
only included the complete automation
solution and the machine clothing but

also had these components optimally
matched to the paper machine in preliminary
trials. For a trouble-free startup
curve, forming fabrics, press sleeves,
press felts and dryer fabrics from Voith
Fabrics were used as initial machine
clothing.
The extensive Voith Automation solution
includes the process, quality control and
information system and extends from the
preparation of the raw material to the finished
end product. The web browser
makes all current and historical machine,
process and quality data mill-wide available
in the information system. This facilitates
easy access to data for the planning
of optimization work and for trouble-shooting.
The automation system was
subjected to extensive functional tests in
„Factory Acceptance Tests“ at Voith so

that a tested and pre-optimized system
could be successfully installed.
Ahead of time
Project handling with the Process Line
Package, proven technology based on
the One Platform Concept as well as a
successful system partnership have
proven very successful at LEIPA. Since
production commenced as early as four
weeks ahead of the agreed date, the further
optimization phase also went off
very successfully.
The intermediate trial 1 was brought forward
by 7 weeks and intermediate trial 2
even by 6.5 months: on October 13 the
two trials were successfully completed
together.
