training every day for another six weeks. We
went over everything chapter-by-chapter, focusing on how one part of the process fits in with
another. Then we had vendor training-how
to make a forming section wire, a felt, how to
define problems, what the structures are made
of, etc. Albany International's training was especially good in this regard. They have done a
really good job here. Nalco came and gave us wet
end training, yankee coating training, creping
blade geometry training, etc. Altogether, we did
about 20 weeks of training," James explains.
Pankratz points out that another thing being
done at Natchez is a tech system. "If we can get
everybody up to our Tech 1 level (what we used
to refer to as machine tender), instead of having
four machine tenders to run a machine-one
on each crew-we are going to have 12, 14, 16,
etc.-the entire crew. When/if an individual is
capable of learning and performing at the Tech
1 level, that's the "bucket" we will put them in
and pay them accordingly. Nobody has to wait
25 years to get to Tech 1 level. And the ones who
shine move right up," he explains.
Pankratz adds that "The guys Gary brought
in here (operators/team) had good work histories and high mechanical aptitudes. We developed a really good team in the short amount
of time we had. We ended up having to shuffle
around wages and a few things. The corporation
had not done anything this big before."
The 30,000 tpy Advantage NTT tissue machine
is 2.6 meters wide, with a design operating
speed of 2,000 m/min. It has a profiling headbox, a four-roll forming section, suction turning roll, Valmet press, and dilution control.
The cast iron yankee is 18 ft. in diameter, with
insulated heads, It also has a profile steam box.
The machine has steam decks around the top to
help dissipate any condensate from anywhere.
The machine has a Valmet IT scanner (IR
scanner), mist collection on the wet end, and
a solid reel drum. The reel section is fullyautomatic, as is roll handling. A 1,200 HP fire
tube boiler fired by natural gas was brand new
with the operation. The 30,000 sq. ft. machine
room is designed to be expandable to accommodate a second tissue machine, with common control rooms in the center. The machine
building complex includes a 12,000 sq. ft. roll
Regarding the choice of a cast iron yankee
rather than a stainless steel unit, James says
that, basically, he prefers a cast yankee. "How
you treat it is how it treats you back," he points
