The Austrian Sappi plant is located in Gratkorn near Graz. The
production facility is one of the largest paper producers for
coated papers worldwide.
The bigger of the two paper machines alone has a production
capacity of 620,000 tons paper p.a. When looking at the more than
240m long machine in the gigantic production hall you get an
impression of the tremendous technological achievements needed for
being able to hold a perfect sheet of paper in your hands at the
end.
Because of the high cutting volume and consistent
modernisation of the machinery Sappi decided to invest in another
POLAR cutting system. The fully automated cutting system T-176-T
PACE* is considered to be one of the most innovative systems
worldwide. The entire loading and unloading, as well as the cutting
process, runs without any human interaction. The simultaneous
automated unloading of the cut products via the rear table AND the
front table is unique.
Peter Pichler, the project leader in charge at Sappi is
extremely satisfied with the output of the system. "The system
works very efficiently and despite the high weight of the 7S format
it remains within the narrow tolerance of +/- 1 mm during
stacking."
While briefly touring the finishing area we see two re-piling
devices and five cutting systems - four of which are from POLAR.
"We had precise ideas what the new cutting system was supposed to
deliver and we talked to all potential suppliers. But only the
POLAR convinced us." While he talks, Pichler points to one of the
fully automated industrial trucks that move through the hall as if
pulled by an invisible hand. "Although only 1.5-2 percent of our
production is cut here on request, we handle more than 13,000 tons
of cutting material per year. In this respect we have relied on
POLAR for many years. Considering the large cutting volume, cutting
has to work smoothly."
Operating the system requires only a minimum of personnel:
the operators will provide one full and one empty pallet, start the
cutting process, and will then move on to one of the other cutting
systems, in order to cut material manually there. When, after
approximately 20 minutes, the pallet is ready, the operators will
come back and start the same process again. Thus, the system has a
throughput of approximately 40 to 45 pallets of cutting material
per day.
In Gratkorn, Sappi handles up to 860,000 tons of coated paper
per year with two paper machines. Since many of the paper making
and customising processes are highly automated, you only meet few
people in the plant despite a staff of roughly 1,400. Pichler is
happy about the smooth cutting process with POLAR: "Based on our
experience with the PACE system we will increasingly opt for fully
automated cutting in the future."
* PACE is an acronym for POLAR Automation for Cutting
Efficiency. These are cutting systems capable of performing one or
more steps fully automatically (without any operator).
