To quote from the Alliance 1997 Annual<br />
Report, “Buyers are extremely satisfied<br />
with the papers, which have been lavishly<br />
praised by many customers.”<br />
In November 1997 Alliance launched the<br />
“Eminence” brand, soon followed by<br />
“Eminence Plus”.<br />
“Offering excellent printability, Eminance<br />
papers have received a good market<br />
acceptance and are highly praised by<br />
many of our customers” said Pierre<br />
Monahan, President and CEO of Alliance<br />
Forest Products Inc.<br />
This high praise notwithstanding, optimization<br />
continues as Alliance drives<br />
toward better and better quality. One of<br />
the principal players in this project is<br />
Jacques Perrault, well known in Canadian<br />
as well as international papermaking<br />

technology circles. Let Jacques have the<br />
last word on the machine:<br />
“Thanks to the ModuleJet dilution headbox,<br />
PM 5 has consistently produced<br />
excellent dry weight profiles, as shown<br />
by 2-sigma spreads typically between<br />
0.12 and 0.17 g/m 2 . Such a level of profile<br />
uniformity is clearly beyond what<br />
could be achieved with a conventional<br />
headbox. This was of prime importance,<br />
considering the use of soft calenders.<br />
Roll build and pressroom performance<br />
reflect these very good profiles.<br />
Although the forming section is still being<br />
optimized, the sheet generally shows<br />
a ‘smile’ z-ash distribution, with basically<br />
no two-sidedness.<br />

good because of very short web trans-<br />

fers from the press and throughout the<br />
dryer section, the use of DuoStabilizer<br />
boxes and vacuum rolls, as well as operating<br />
with very light draws. A clean operation<br />
of the DuoFormer CFD and the<br />
DuoCentri press in addition to the use of<br />
slotted screens in the stock system contribute<br />
to this strong performance“.<br />
The Donnacona project team is almost<br />
unchanged from that responsible for the<br />
Dolbeau PM 5 rebuild. This was an excellent<br />
example of how well the <strong>Voith</strong> Sulzer<br />
<strong>Paper</strong> Technology partners work «twogether».<br />
Although the major supply was<br />
from Appleton, entire aggregates were<br />
delivered from Middletown, Krefeld and<br />
Heidenheim, with significant components<br />
from Brazil and Ravensburg. The successful<br />
integration of all these parts into<br />
the machine reflected the successful<br />
merging of the two companies.
