Wire line launched
❍ The new Fuhr copper wire line in action at Düsseldorf
At wire Düsseldorf 2010, Fuhr GmbH
& Co KG took the opportunity to
introduce its latest development for
the production of high-precision
rectangular copper wire.
Its largest-ever booth (over 1,000ft2)
allowed Fuhr to display an entire rolling
mill, capable of processing copper
wire, in real-time, from round to
rectangular wire. The end result is said
to have tolerances of ±0.005mm with
excellent surface quality and material
properties.
The company reports that a large
number of visitors came to watch the
operational capability of the machines
and to view the quality of the final
product.
Featuring a combination of a horizontal
spooler (payoff), a two-high rolling
machine (WSR-type), two edge-rolling
devices (WSE), two Universal Turks
Head (WST) rolling machines, as well
as two combined dancers, three
Vollmer measurement systems and
an oscillating spooler, this very
compact rolling mill is thought ideally
geared towards the production of
high-precision rectangular copper
wires (such as CTC) or copper flat
wire, such as PV ribbon (interconnect
wire and bus bar).
In general, applications for CTC cables
are windings in transformers, motors
and generators. Furthermore, high-
precision rectangular copper wires
with small cross-sections are being
used for high-efficiency hybrid motors
and wind generators.
With the emergence of CTC cable
and its related applications, the
required tolerances for these rec-
tangular wires have been reduced to
±0.005–0.010mm, which cannot be
achieved with traditional cold rolling
technology.
Fuhr’s contemporary layout of its
wire rolling machines offers a rolling
mill capable of processing copper
round wires into a wide range
of rectangular and flat shapes,
achieving width to thickness ratios of
up to 40:1.

Paul Leibinger GmbH presented its
latest product at wire 2010: a com-
bination of camera system and inkjet
printer to control printed information.
Designed as a plug- and-play solution,
the verification system is installed and
connected to the Leibinger JET3 inkjet
printer.
During production the control and
monitoring of the JETvisio is made
directly on the touch screen of the
JET3. The fully automatic visual moni-
toring system JETvisio guarantees
highest reliability of product marking
and prevents the production of
defective goods.
Leibinger software ensures perfect
coordination between the camera and
the printer.
