Tyre Asia April/May 2018 103
Quality requirements are constantly
increasing, driven by the automotive
industry not only as a result of tyre
labelling, which has been mandatory
in the eU and South Korea since
2012, but also due to the requirement
to sign oe tire sizes visually on the
sidewall. The above prerequisites
will also increase in the coming years
in other markets such as the US,
china, Brazil and Japan as a result of
the pending launch of the labelling
regulation.
There is the need for extremely
high levels of repetitive accuracy
and quality. TBMs need to meet
the requirements of manufacturing
efficiency, particularly new tire
designs.
The Group’s TBM team has been
working on the development of hF
one for over two years to ensure
its adaptability to all kinds of tyre
designs. The result has been greatly
rewarding. The introduction of the
machine at the hannover expo
evoked very positive response from
tyre manufacturers who visited the
hF booth.
hF one can run three possible
carcass drums. It enables quick
change-over – less than 20 min - of
different carcass drums without
changing the shaft, he pointed out.
The long-hub machine delivers high
force and the servo is driven for
symmetrical turn-up movements.
hF stressed that hF one answers to
the need for ensuring the tyre’s top
quality. There is less stress on ply
due to flat turn-up. Some of the other
operational features include separate
IL and SW application, no ply ending
in SW area due to c turn-up, constant
cord length bead to bead, very
accurate SW inboard edge application,
ply-down to reinforce the carcass,
and automation of former two-stage
process with permanent bead control.According to hF, the new TBM
efficiently ensures tyre uniformity
and enables material cost reduction.
A major advantage, he said, is that
it helps reduce tyre weight – one
of the most important factors in
automobile weight reduction, which
helps energy conservation. There will
be no sidewall cracks when tyre is inuse due to elimination of ply ending in
sidewall area.hF`s TBM division has already
successfully put hF one machines
into operation and is set to meet
future demands.
The reliability of hF’s TBM systems
has been of the highest standards. The
need for maintenance is very low. This
is because all wear parts are inspected
on a regular basis and exchanged in
time when necessary. The group is
constantly working on improvements
and optimisation of its components so
that the tyre makers’ systems remain
technically up-to-date.
Since hF has a global presence, its
services remain close to customers
anywhere in the world.Contact HF TBM division for more
