to perform their respective task. As a result, the sys-
tems also achieve a higher throughput rate, which is
reflected in significantly better economic figures. Taking
the example of a fictitious average-sized car tyre manu‑
facturer – with five tandem mixing lines and production
of ten million tyres per year – Keuter calculated a po-
tential annual saving of almost one million euros com-
pared to a similar production set-up using conventional
mixing lines. This creates an enormous competitive
edge which is sure to resonate among the manufacturers
in the hard-fought global tyre market. (See page 26 for
more information on the tandem process.)
The wheel was invented more than 6,000 years ago
and its basic function has remained unchanged ever
since. The technological possibilities of the tyre, how-
ever, have certainly not yet been exhausted – as the
‘Science meets Tires’ conference clearly demonstrated.
New developments are constantly emerging as a result
of cooperation between research institutes, the tyre
industry, automobile manufacturers and technological
suppliers like the HF MIXING GROUP. New measuring
methods are also helping to gather ever more detailed
information about the physical and chemical processes
in tyre material, about the tyre structure and what hap-
pens at the interface where the tyre meets the road. As
such, it will be interesting to see which findings and
new developments will be presented at the ‘Science
meets Tires’ conference in 2014.
Dr Harald Keuter (HF MIXING GROUP) calculated a potential saving of up to one million euros by using tandem mixers.
