Addex launches Short Stack
blown fi lm cooling system
By David Vink
Plastics News Correspondent
Newark, N.Y.-based blown fi lm
equipment supplier Addex Inc.
came to K 2022 with a new Short
Stack version of its intensive cooling
system. The new equipment promises
a typical 25 percent increase
in output compared with the company's
fi rst " Down-on-the-Die " intensive
cooling system, which was
fi rst introduced at K 2016 and had
already achieved 10-15 percent improved
output over the conventional
dual-fl ow air rings of that time.
Addex President Robert Cree
recounted to Plastics News at K
2022 that the company he founded
in 1989, after working in Mobil
Chemical's research center in the
1980s, was originally involved with
full blown fi lm extrusion lines before
Cree decided to specialize on
cooling. He described how the latest
system cools already from the
die " up to where the thickness is
measured. "
The productivity gains with
the system fi t in well with present
strong interest in saving resources.
" To be a good citizen today, you
have to be green. I am glad to see
the industry has stepped up and is
challenging itself, which is fabulous,
an excellent approach, " Cree said.
One key issue, however, is to
get hold of experienced people to
run blown fi lm lines. This means
operators are also often " green, "
he chuckled, and suggesting some
fresh thinking is required.
It is therefore benefi cial that all
Addex equipment comes with an
operator assist system, symbolized
by the letter Å, which simplifi
es operation.
" It means you just have to push
one button and it does the rest, "
Cree said. Bearing in mind there
are many blown fi lm lines in operation,
Cree said not everyone can
afford a completely new modern
line. This is one reason why Addex
focuses on supplying its equipment
as retrofi ts for existing lines.
And there is a real need, Cree
said, " as the newest, therefore less
experienced operators tend to be
applied to old existing lines, in a
belief they can't do much harm,
while experienced operators are
trusted to be allocated to expensive
new lines. "
The Addex system is accordingly
simple to operate, due to the
fact its height is not adjustable and
an additional three points of bubble
stabilization.

is started up and the bubble cage
begins to move. Four ultrasonic
sensors are fi tted to the cage

and move with it, and
there are another four
mounted on the top of
the cage. Should the
bubble become too big,
the sensors detect this
instability and can get
the cage to respond
and restabilize before the bubble
hangs up or becomes damaged.
This is achieved by changing the
relative speed of the blowers via
digital internal bubble valve to
ensure correct vertical and horizontal
positioning for the correct
bubble diameter via step motors.

system is the aerodynamic
approach, whereby
additional high-velocity
air streams have
been added to the
traditional commonly
used single high-velocity
main lip air stream.
This improves cooling but also aids
bubble stability by helping to hold
the bubble better in place.
And fi lms that are diffi cult to process
can be run at higher speeds,
as cooling starts just above the
die lip. Increased bubble stability
makes it easier to process lower
melt strength materials.
