automated wire production
Weaving ideas from
metal wires
Haver & Boecker, Germany, began
production of woven wire cloth
in 1887, and today has production
sites in Germany, UK, Belgium, USA
and Canada.
The company uses the latest pro-
duction technology and equipment,
as well as a sophisticated quality
control, to provide wire cloth for any
application, including screening and
filtration in many industries: chemical,
plastic, automobile, aeronautic, aero-
space, electronic, industrial screening
(mining and quarrying), test sieving,
and food.
Wires as thick as 16mm (0.63")
diameter down to those of only
0.016mm (16 microns) are woven
according to ISO 9044, using state-
of-the-art machinery and a team of
qualified experts.
Haver woven metal wire cloth is also
used for exterior and interior archi-
tectural design applications, such as
façades and ceilings.
Haver & Boecker meshes are
available in many different patterns,
each with its own characteristics in
terms of strength, transparency,
metal density, surface finish and
optical effect. This results in an
attractive, strong and manageable
material. Haver architectural wire
cloth has been used in internationally
renowned architectural projects.

Meltech announces the DR-1000
for automated take-up
Wire processing specialist, Meltech Engineering, has recently announced the MT-DR
1000, the latest addition to the DR series of automated dual reel take-up machines for
continuous production of wire and cable.
The MT-DR 1000 features a 1,000mm reel size with winding speeds up to 750metres per
minute for data communications and LAN cables, general wiring and heat shrink and
wire tubing applications.
Accurate winding control lies at the heart of the MT-DR 1000. Meltech’s control
technology calculates the precise tensioning of the wire during winding. The control
system also features a selection of manufacturer specific recipes, based on winding
pitch settings, drum sizes and optimum layering patterns. In addition the take-up
machine’s control system to give improved winding control, layering, and speed and
length control at point of changeover.
The MT-DR is a robust machine that can be readily integrated within an existing wire
production line. The Meltech dual reel take-up machine is available in both semi and
fully automated operation.
The DR 1000 compliments Meltech’s approach to manufacturing silicone rubber coated,
single and multi-core wires, and low-halogen jacketed cables. It offers a complete
production line, yet requires less space than existing lines, and with higher production
speeds.
Traditional silicone rubber coating of wire has meant feeding the coated wire through
salt baths or steam to provide the heat needed to cure the coating. Typically the baths
can be up to 100 metres long, from which the wire emerges and is then dried.
Meltech uses an infra-red oven to heat and cure the silicone rubber in a fraction of the
time taken with salt baths. And at 12 metres, the oven is also significantly shorter,
reducing the space needed for coating operations.
In combination with Meltech’s automated pay-off and coiling machines, manufacturers
can expect to achieve typical production speeds of up to 140 metres per minute.
