the formers so the sheet touches the ceramic roll
twice in the press section to get a smoother sheet
for printing," Hewitt explains. It is 356 in. wide
at the wet end. The headbox is a SymFlo dilution

model. The machine is balanced at 3,500 ft/min,
but production speed is 3,000 ft/min.
The press section features a tri-nip press with
a shoe press in the third position. Pressure in the

The machine has a trim width of 330 in. and "runs like a top," Hewitt says.

Siemens supplied all 16 transformers and sub-station.

Hewitt says that the mill has developed a "recipe" between short and long fiber that optimizes strength.

shoe is 6,900 pli. The center press is a ceramic
roll. The entire vacuum system is MAN-Turbo
blowers. There are no water ring vacuum
pumps. There are five dryer sections in the
pre-dryer: the first two uniruns and the final
three double felted. All have ropeless threading.
The system includes a ValSize rod metering
size press where the surface starch is applied.
A brown dye is also added to the sheet to give
it the look of kraft linerboard, "because that's
what we're selling," Hewitt says, "an alternative
to virgin kraft liner with the same look, feel
and strength."
The after-dryer section has one unirun and
one double felted section. There is a ValHard
calender, but it sits idle as the mill has found
it does not need it.
There is a QCS scanner at the OptiReel and
a Ryeco edge crack detector. The winder is the
WinDrum model with automated slitters, and
Raumaster supplied the automated production
system for cores. Trim width off the winder
is 330 in.
Roll handling (Valmet) is also automated.
The warehouse is totally automated with Kone
cranes and Raumaster grippers.
Hewitt says the paper machine is really
solid-"it runs like a top." At its trim width of
330 in., it is "three wide"; that is, the standard
size for corrugators is 110 in. and that "should be
around for a few years," Hewitt adds. At capacity, the challenge is logistics, getting rolls in and
out of the warehouse. The mill's production
record so far is 45,300 tons, set in May 2017.
The paper management system, or MES, is a
legacy system from Cascades. Other than that,
the entire mill uses an SAP system.
In terms of power, Siemens supplied all the
transformers (16) and sub-station. The mill
purchases its power from the national grid
and needs about 28 MW. Part of the incentive
program was 10 MW of cheaper power from
the New York Power Authority.
Siemens also supplied the automation system: the PCS 7 platform. There is a ProfiBus
DP&PA system for instrumentation and control. The machine control system from Valmet
runs on the PCS 7. This applies for the QCS
as well. All instruments, motors, and drives
came from Siemens and all pumps are Sulzer
(purchased through Siemens).
Kemira and Buckman are the mill's main
chemical (retention and drainage aids, biocides) suppliers.
At the outset, Cascades decided to outsource all maintenance for the Greenpac site,
including the grounds and building, plus
