30%), which eliminates the Yankee as a
bottleneck and raises overall production."
SCA did not want a "cookie cutter"
machine and wanted to be actively
involved in the machine design according
to Phiscator. Voith Andritz Tissue*
received the award for the stock preparation
plant (100% recycled) and the
machine. The rewinder was also added
to the package.
The Andritz machine at Barton (PM12)
is a straightforward twin-wire design with
suction forming roll designed for napkin
and towel grades. The design capacity is
390 t/d, with a basis weight range from
11-33 lbs (17-53 g/m 2 ). The wire width is
just over 225 inches (5720 mm) and the
trim at the reel is 216 inches (5500 mm).
The maximum drive speed is 6100 ft/min
(1850 m/min). The afterdryer section is
modeled after SCA's #4 machine in
Menasha, Wisconsin.
"Andritz was receptive to our needs
and was willing to work with us on the
wet-crepe design," Phiscator says.
"They were very professional — and
still are. Every aspect of dealing with
Andritz has been good."

"Massive machine"
"I was very impressed with the quality of
the construction when I saw it being built
in Austria," says Phiscator.
"The frame is very heavyduty
and the design is well
thought out. It's exactly what
we were looking for."
John Prusynski, Maintenance
and Engineering
Superintendent, agrees.
"The Andritz machine is by
far the best piece of equipment
at this site,"
Prusynski says. He was
responsible for the vibration
analysis program at
Menasha for almost 10
years. "So, I know what
acceptable machine vibration
is," he says. "When
we did the speed run on
the Andritz machine at
6000 ft/min (1800 m/min)
I have never seen a mach-
ine run that smoothly."
End of ramp
Now about a year and one-half into the
start-up, the target is to achieve 100%
efficiency (what the Barton people call
"end of ramp"), according to Merle Stein,
Paper Manufacturing Superintendent.
The end of ramp for Stein's team is the
design specs guaranteed by the machine
manufacturer. "Right now, we're working
on consistently achieving design production
for the Andritz machine," he says.
"Once we reach that peak, we'll set a
more aggressive target."
"My experience at Menasha was on
the fiber preparation side, so I was able
to contribute my experience to the
Barton deink plant design when I started
on this project in 2002," Stein says.
"Things really started to get busy here
when we brought the first crew in for
training in October 2003. Of the original
36 technicians hired here, only
three had papermaking experience.
So, there was a lot to learn. It's been
exciting to be a part of the process."
