re昀椀ning de昀椀nes success
Martin Koepenick, Innova International
INTRODUCTION:
The centerpiece of success in tissue making is always the same: tensile strength, absorbency and softness, the order of importance
depending on end use. For paper towels, absorbency is supreme. For toilet tissue, softness and touch play a de昀椀ning role. At Industria
Cartaria Tivoli, a recent advance in re昀椀ning was driven by spiraling energy costs. But in the end, 昀椀ne-tuning 昀椀ber properties is the biggest
gain.
The team at Industria Cartaria Tivoli turned to AFT to provide
their new MaxEdge™ low consistency re昀椀ner and customized
Finebar® MiniSegments™. This compact and energy ef昀椀cient re昀椀ner
does the work of the traditional two larger re昀椀ners.
“Soon after installation of the MaxEdge re昀椀ner, energy usage
dropped by 40% and steam savings were achieved. Also critical to
success are enhancements to our 昀椀ber—not over or under-re昀椀ning.
There is an art to optimizing the properties you seek when you
make tissue and toweling. The MaxEdge re昀椀ner equipped with
Finebar MiniSegments delivers precisely that,” says Tomas Saliola,
Maintenance and Operation Manager at Industria Cartaria Tivoli.
The team at Tivoli had very speci昀椀c objectives for strength
and absorbency, which were achievable because of the AFT
MiniSegment design.
“AFT understands the nuances of tissue making, which is
an advantage for us,” comments Mauro Caponi, Shift Leader at
Industria Cartaria Tivoli. “The baseline property for successful tissue
making is tensile strength – both dry and wet. Building on strength,
softness and absorbency can be enhanced. Re昀椀ning with precision
is critical to meeting the speci昀椀cations needed for a wide range of
end-use products and customers. The support from AFT to achieve
greater control of the process is a big plus. Also, IoT integration
gives us better re昀椀ner performance, ease of operation, and assures
safety too.”
A re昀椀ner, yes, but what else to achieve results?
Emidio Lo Monaco, AFT representative and CEO of Techno
Paper Srl, emphasizes the importance of a re昀椀ner. “Flow control,
energy requirements, sizing of valves, pumps, recirculation - many
tissue systems fail because of poor installation.
Not taking care of correct recirculation is a common
problem. Each grade has its unique needs. Proper 昀氀ow through the
re昀椀ner is critical.”
Risk to over-re昀椀ne or under-re昀椀ne
AFT Application Manager Francesco Pantanella notes that
energy must be applied in a particular way. “For tissue making,
the importance of re昀椀ning is far more than seems apparent. It’s all
about 昀椀nessing the 昀椀ber. There’s never a straightforward formula.
It’s always unique to the application. Finebar offers a wide range of
plate pattern options to achieve this.”
Says Caponi, “Bulk matters, especially for toilet tissue. Of
course, runnability has to be at a steady, high-performance level.
MaxEdge and Finebar technologies allow the team here to meet our
targets consistently.”
Safety and ease of handling
Finebar MiniSegments are the ideal complement to the
MaxEdge re昀椀ner—each segment light enough to hold in one hand.
“Quality of tissue is essential to success. By our de昀椀nition, this includes the process ef昀椀ciency in
making the tissue. Re昀椀ning just right is a must.”

The sound of success? This compact re昀椀ner actually
has its own steady, quiet hum. It’s telling you that
re昀椀ning is going well, using less energy. Francesco
