Measuring tools for optical alignment checks
• Alignment is checked with the
help of a leveling instrument, a
tachometer
• We also use a number of
proprietary measuring aids that
have undergone extensive
development work
• Tachometer software is tailored
for paper machine alignment
applications

MX06 PROPERTIES
MX06 is a fluorine based layer
Durability doubled compared to Teflon
Forms a thin layer, normally 0,001-0,002 mm
Teflon-treated surfaceUntreated surface
• Treated surface becomes water-repellent
• Stands all cleaning chemicals, both acid and basic
• Except for metals, polymers and ceramics can be treated with MX06
• Prevents/reduces Headbox contamination and build-ups
• 30h On-site application, 8-12h drying time

Alignment & Re-alignment of Corrugators
Customers’ feedback:
Monday, 20 August 2012
“Our experience with Metso Paper started back in 2007 when we
measured and realigned our corrugator for the first time. We used their
services again in 2010. When we took the decisions to install our new
corrugator in 2011 there was no doubt that we should use the expertise,
experience and service from Metso Paper to assist and support us during
the different stages of the installation. We were very pleased with Metso's
flexibility and respond to our demands and above all the high standard of
service. We can highly recommend working with Metso when
installing a new corrugator”.

"Metso Paper responded quickly to our request for help, the job was made
very professionally, we were very satisfied and happy with the latest service
and with the service technicians we had on-site.
We have nothing to complain about, well done job.
We can see an improvement in the tension in the paper path, and less
warp.
It is important that the machine elements are align to each other.
I would recommend others to do the same”.

Alignment & Re-alignment of Corrugators
Customers’ feedback:
Increasing in board strength on C and B Flute
E-mail: 15. juni 2011
Hi Ram.
Yes I think so, the miss alignment in our machine probably
gave us more problems than first imagined.
Med vänliga hälsningar/Best regards

Results after corrugator Re-alignment:
a. Satisfied with the work done by Metso Paper and the Metso’s personal on-site.
b. Much better paper tension on the corrugator.
c. Much better temperature distribution across the width on medium and liners at all positions.
d. Big improvement on board quality in manufacturing E-Flute.
e. Corrugator in general is running better.
f. Good results with the re-alignment of the roll-stands
g. Triple stack was the major problem before the project, good improvement after the re-alignment.
h. Metso Paper is much more experience and are using better equipment comparing with BHS.
i. I think it is a very good idea to have Metso Paper on site during installation of a new corrugator. I
believe this could solve us a lot of issues in Värnamo when we installed the corrugator about 8 years
ago.
j. Good value for the investment

Stage 2: Re-alignment of Corrugators
The re-alignment process of the corrugator will be based on the
results and finding in stage1 (corrugator alignment measurement)
The most “critical” mis-alignment areas that has been founded in
stage 1 would be re-aligned (adjust)
New or adjustment of the existing reference line for the corrugator
Time consume between 2 to 4 days, depending on how much work is
needed to be done
Help and support from the locale maintenance team
Extensive and detailed report that summarize stage 2 will be
delivered to customer
