SPe CIAL
ALUMINIUM ROLLING INDUSTRY
Danieli Fröhling is satisfying these market requirements
by developing and manufacturing
high-speed slitting lines. However, this necessitates
optimisation of the circular knives,
their structural design and the rigidity of the
whole knife shaft system, including finite element
analysis, as well as the choice of cutting
gap and depth of penetration, which determine
the quality of the cutting process.
The development of CNC-controlled slitters
and trimming shears is one of the most
important innovations in the company’s 65-
year history.
However, it is not only the cut that determines
the quality of the finished coils: exact
winding is also part of the customer’s requirements.
By using its vacuum technology as the
braking stand, Fröhling has set new standards
and can point to over 30 vacuum rolls that
are already in use at leading strip producers
worldwide.
As a technological entity, cutting with circular
knives together with braking and coiling
requires a powerful measuring system
for determining the instantaneous operating
state in real time if an optimal interplay is
to be achieved. This includes highly accurate
measurement of the speed as well as optional
measurement of the strip thickness.
Thanks to its non-contact mode of operation
and the fact that it provides an opportunity
to have a powerful interface, the ASCOspeed
is used preferentially as the speed master in
strip plants, supplies the information for synchronisation
of the knife shafts and on the
instantaneous strip length, and can also used
with a slack-loop pit for control purposes.
Cutting machines from Danieli Fröhling
are very popular worldwide thanks not only
to their quality and performance but also to
the high-precision measurement technology
from Micro-Epsilon that is used.

3 rd Global Aluminium Foil Roller Conference on the horizon
The European Aluminium Foil Association
(EAFA), the global network leader of foil
producers, is organising the third Global Aluminium
Foil Roller Conference (Glafco), which
will be taking place from 15-17 January 2014
in Dubai. Delegates from the international
aluminium foil roller industry are expected
to continue the coordinated actions on foil
sustainability and promotion to support market
growth globally and highlight innovative
developments.
Stefan Glimm, executive director of EAFA, comments:
“Our objective is to gather more than
90 percent of the global foil market in Dubai –
ten percent more than last time. The industry
wants to continue building one global voice
for foil on sustainable and promotion issues to
support further growth. Both in packaging and
technical applications aluminium foil has the
great advantage of saving more resources than
it consumes, through the complete value and
supply chain.”
The first joint project ‘A Global Moment
with Alufoil’ was launched at the last conference.
It comprises a brochure in several
languages and a multilingual website www.
global-alufoil.org. The report demonstrates
alufoil’s versatility, through the multiplicity of
applications for which it is suitable. In addition
it shows the methods the industry is using to
provide solutions for a world facing growing
population, urbanisation, climate change, and
depletion of scarce resources.
The conference is open for foil rollers
worldwide. The programme includes the following
presentations:
• Global Economic Outlook
• Africa – the Hidden Growth Potential
• Outlook on the Global Primary Aluminium
Industry
• Global Foil Stock Market
• Strengthening Foils’ Competitiveness:
Contributions from the Suppliers’ Side
• Global Foil Markets – Trends, Challenges
and Opportunities
• Foil around the Globe: Country reports on
China, Europe, the Americas, Japan, South
Korea, India and other Asian and Middle
East Countries, Russia/Armenia, South
Africa
• Customer Perspective
• The Place of Foil within the Packaging
Material Portfolio of a Brand Owner
• The Future of Foil in Global Flexible

• High-tech Aluminium Foils in Li-Ion-
Batteries for Transporation and Energy
Storage
• Sustainability – the Aluminium Story
• Foil Recycling and Recovery Options
• Aluminium Recovery for Laminated Foil
Packaging
• Driving Value in Beverage Carton Recycling
• The Aluminium Stewardship Initiative: a
Responsible Path for the Development of
Foil Markets
• Global Foil Roller Network’s Future
Stefan Glimm: “The industry wants to continue
building one global voice for foil on sustainable
and promotion issues to support further
growth.”
• Resource Efficiency – Foils’ Key Branding
Opportunities and Activities of the Glafco
Network since 2011
• The Future of the Glafco Network: Ideas,
Discussion and Conclusions
• Conclusions from the Supplier View
The conference is accompanied by an social
programme including an afternoon exploration
of the desert with 4WDS followed by a
sunset dinner at a Bedouin desert camp . For
