Wire Drawing Machinery
49 Wire & Cable ASIA – March/April 2007
Wire drawing is one of the most
sophisticated processes in the entire
field of industrial practice
The Devil’s Rope Museum, in McLean, Texas, USA, on Old Route
66 in the Panhandle, bills itself as the largest museum in the world
dedicated to the history of barbed wire. Its claim is not disputed
by this journal, which is indebted to the museum for supplying
the earliest known written reference to wire manufacture: “And
they did beat the gold into thin plates, and cut it into wires.”
(Exodus, Chapter 39).
The word ‘plates’ in the ancient text is an eye-opener, even if thin gold plates from three millennia
back have no direct connection with the draw plates in series that reduce the cross-section of the
product of a modern wire making plant. Wire drawing is one of the most sophisticated processes
in the entire field of industrial practice. But in both instances a painstaking procedure is employed
to produce a valuable commodity. The methods of both sets of technicians are carefully noted for
future reference. Most important of all, the world – of yesterday and today – is the richer for their
efforts. That will be true as well for the world of tomorrow.
The wire drawing specialists that appear in the pages that follow are in that tradition. Evolution is
the nature of their business, as demonstrated by the machinery featured. What was state-of-the-art
last year has in fact been improved upon. The editors of Wire & Cable ASIA take keen satisfaction
in reviewing these superb products and services.

Maximising performance
From their inception the companies
RTM (Redaelli Tecna Meccanica),
Italy, and OTT, France, became
synonymous with high carbon steel
wire transformation machinery.
Since 1999, these two wire and rope
machinery companies have become
the wire machinery division of
Continuus-Properzi SpA. A year later,
Continuus-Properzi SpA introduced
the new generation of the dry drawing
machine the ‘MegaLogos’.
The primary concept was for the
design to be ergonomic to make
operation easier and maximise
performance. Thanks to the high
performance of the capstan and die
cooling technology, the lack of wire
path deviation, better back pull control,
the complete lack of wire torsion, and
the use of the most modern inverters
and motors, the MegaLogos has
established a new class of drawing
machine providing optimal quality and
performance. Inherent to the horizontal
capstan design machine are greatly
reduced down time and maintenance.
The use of the most modern design
and components reduces power
consumption and with the easy
maintenance allowed by the horizontal
design, the MegaLogos again proves
itself as the optimal machine design
across a broad range of products.

The EVO 3 water-cooling of the
capstans is the result of many years
of successful and proven experience
in the cooling of hot casting lines and
assures maximum wire quality and
production speed with reduced water
consumption.
From Redaelli and OTT’s many years
of experience and the continuous
research into the use of modern and
dependable technology, through
Continuus-Properzi, the wire
machinery division has proved to have
a specific strength in PC wire and PC
strand machinery.
