The pro le surfaces are also made
extremely wear-resistant through targeted
inductive hardening.
The process of cold rolling is new at
Zollern. This procedure is particularly
suitable for the manufacture of small
pro le geometries which are required
in larger quantities. Multiple rolling
machines in a production line carry out
this procedure automatically, adhere to
the narrowest tolerances and provide the
pro les with a high surface quality.
Zollern steel pro les are represented
in many industrial branches. They are
used, for example, as ball and roller
rails for linear guides, as steering and
adjustment systems in automotive
construction, as clamping elements for
free-wheel products, cutter holders and
harrow blades for chopping tasks, thread
guides and pull-o rollers for knitting
machines, key bars and dovetail bars in
generator construction, locking pieces for
hunting and sports weapons, kelly bars in
deep-drilling technology or as clamping
jaws, sliding blocks and guide rails in
mechanical engineering.
Over the past two years, Zollern has
invested over €20m in its modern steel
pro le production at the Laucherthal plant
in southern Germany.

Zumbach will showcase its extensive
portfolio of dimensional measurement
and inspection systems for wire drawing,
wire insulating and cable jacketing
processes as well as for rod and bar mills.
In order to achieve high precision and
best price-performance ratio, di erent
technologies such as laser scanning,
X-ray, ultrasound, light-section technique
and linear sensor technology are used.
The production of o shore exibles
involves complex processes requiring
varying individual performances for quality
control.
Any deviations from the required standards
can risk serious consequences if failure
occurs, depending on the application
scenarios.
In order that the risks for future
product failure are eliminated during
the manufacturing processes, such as
wire drawing, pro le rolling/extruding,
stranding and sheathing, Zumbach
provides reliable solutions for the
measurement of all critical parameters.
even for very low cable tensions, to avoid
any extra detrimental bending on the
cable.
WTM’s Visio system will be installed in the
displayed line. This electro-optical control
system, available in several con gurations
and with a variety of options, magni es
the cable surface image during the
production process: measurements, direct
feedback and real time checking on the
cable surface are now possible.
Data obtained can be stored or sent by
LAN connection to any department for
analysis and for generating statistics,
trends and production diagrams.
The second module on display will be
equipped with the triple motorised
taping head suitable for PTFE. This taping
head is a variant of the previous one, and
is suitable to control the tape tension
directly, immediately before wrapping
point, with the tight deviation of ±50
grams.
In this case, the high sensitivity of the
dynamic dancer gives the possibility
to process the softest and most critical
materials.
Each part of the lines is designed for
processing every kind of cable, including
those used for the most sophisticated
applications: aeronautical, aerospace, IT
communication and military.
A third machine will be presented at the
WTM stand. This is a new single twisting
unit designed for very sophisticated LAN
cables, Cat 5/6/7/7a/8.
Thanks to the newly developed technical
solutions, this e cient unit can also
produce other kinds of precise cables,
like high exibility cables, signal cables
(encoder), cables for robotics and cables
suitable for overhead laying.
The quality of the cables produced is
granted from an accurate control of
the tension on the cable itself because
the machine can work with dancer
or torque control, enabling the best
regulator according the cables’ speci c
characteristics and assuring a wide range
of product processing capability.
The pulling capstan that is rotating,
to grant a constant lay length, can be
excluded widening again the exibility of
the machine.
This machine is suitable to be placed
in line with existing pay-o s or can be
coupled with concentric back twist
feeders. Then the line can be completed
with other equipment and accessories
including various types of tape wrapping
machines for di erent tapes.
WTM understands completely its
machines: the design, the construction,
the assembly and even the software. In
this way, every WTM machine can be
integrated or completed with any other
existing machine or equipment without
problems, even from other suppliers.
These also include laser gauges, spark
testers and any other instrument useful
for the production process, which can
be connected and set directly from the
machine operator panel.

Reducing processing times and material
consumption, steel pro les are on the
advance in modern construction. When
high quality, durability and economic
viability are required, it is worth
re-thinking the use of steel pro les.
Application areas for the pro les include
components with complex shapes
which have to withstand high levels of
strain. Steel pro les convince with their
component and fatigue strength. The
surface quality and dimensional accuracy,
even within very narrow tolerances, ow
directly into the end product. Necessary
re-work is minimal when steel pro les are
used, and the material consumption is also
reduced by up to 60 per cent.
At Zollern, a steel pro le manufacturer,
automated production processes ensure
quality and accurate reproduction of more
than six million metres of steel pro le
which leave the factories annually.
The company has supplied customers
in linear technology, mechanical
engineering, the automotive industry
and other branches worldwide with 8,000
individually adapted designs.
Specialists select suitable material from
200 di erent steels and steel alloys. The
steel pro les feature excellent properties
due to hot rolling, cold forming and heat
treatment.
▲ The special pro les serve as steering and
adjustment systems in automotive construction
