When faced with the task of rebuilding<br />
the No. 96 paper machine, the mill’s project<br />
team faced a number of difficult<br />
choices in order to keep within very tight<br />
budget constraints.<br />
The original Dominion paper machine, installed<br />
in 1979, had a <strong>Voith</strong> W-type headbox.<br />
A decision had to be made whether<br />
to rebuild the original headbox or purchase<br />
a new one. After a thorough structural<br />
analysis, using a finite element<br />
model, it was determined that a special<br />
reinforcing would have to be installed for<br />
the headbox to meet the new design conditions.<br />
The choice was made to rebuild the existing<br />
headbox as originally planned. This<br />
rebuild would incorporate the latest in<br />
Profilmatic M dilution control technology.<br />
The headbox would receive new state-ofthe-art<br />
actuators as well as a new slice<br />
lip and general modification to incorporate<br />
the latest in ModuleJet technology.<br />
<strong>Paper</strong> Machines<br />
Reconditioning of the headbox would be<br />
done at <strong>Voith</strong> <strong>Paper</strong> in Appleton, Wisconsin<br />
during the shutdown to rebuild PM 96.<br />
When the headbox was disassembled and<br />
cleaned, shortly after its arrival at <strong>Voith</strong>’s<br />
facility, unexpected rework of the mounting<br />
plates was needed. The machine shop<br />
at <strong>Voith</strong> <strong>Paper</strong>’s Appleton facility was<br />
fully qualified to handle these unexpected<br />
obstacles and repairs were made without<br />
significantly affecting the overall schedule.<br />
The rebuilt headbox and the new <strong>Voith</strong><br />
DuoFormer D were installed on what<br />
could be considered a model shutdown.<br />
At start-up, salable production was quickly<br />
achieved and the important gains in<br />
paper quality, expected in CD basis<br />
weight profile, fiber angle and formation,<br />
quickly attained.<br />
The Appleton facility is a valuable resource<br />
for <strong>Voith</strong> <strong>Paper</strong>’s customers in<br />
North America. The close co-operation<br />
between the SENA Kimberly mill and<br />
<strong>Voith</strong> <strong>Paper</strong> personnel, in using this facility<br />
to its potential, resulted in a cost<br />
effective project of which everyone can<br />
be proud.<br />
With the rebuild completed on May 10th<br />
2003, the PM 96 production line is now<br />
producing coated paper at quality levels<br />
exceeding the Stora Enso planned targets.<br />

“The rebuild of the Kimberly PM 96 is<br />
an integral part of SENA’s Profit<br />
Enhancement Program launched in<br />
2002 which consists of machine<br />
closures, product transfers, workforce<br />
reductions, and significant capital<br />
improvements totaling 250 Mio US$.<br />
Initial performance of the rebuild production<br />
line shows us that our targets<br />
of quality and productivity will be met.<br />
During this project, the close cooperation<br />
together with <strong>Voith</strong> helped us<br />
meet our goals.”<br />

significantly improved our quality,<br />
further enhancing our ability to be<br />
our customers’ first choice.”<br />
