THE Quick Rolling Concept has been
developed by Eurolls to perform
multiple tasks. Its function is to
produce wire and with a sleek,
compact design/dimensions allows the
perfect union between different wire
processing sequences.
Eurolls has supplied this QRC concept
in both multiple and single in-line wire
rolling configurations. In both cases,
the presence of the QRC unit permits
the combination of different/distinct
processes but always with the same
goal: improved production efficiency
by having in a single line for the
complete process from entry material
to final product.
An example of the multiple in-line wire
rolling solution was its insertion in a
lattice girder manufacturing system
with five individual QRC units, three for
the longitudinal wires and two for the
stirrups wire.
The same philosophy is present in the
case of the single in-line solution that
combined both a QRC unit and a
straightening and cutting line to
produce the finished twisted square
wire in straight lengths.
In both solutions, the first section is
always the QRC unit whose function is
to pull the entry material from the
pay-off area through both mechanical
descaler and cold rolling cassettes, by
means of dual V grooved pulling rings
which guarantee the traction required
to perform the single or double wire
draft. These drafts can be performed
by using either traditional cold rolling
cassettes or a combination of
traditional/special cassettes in
accordance with the profile required for
the finished product.
In the particular case of twisted square
wire production, the first cassette
performs the standard rolling process to
form the correct intermediate wire
dimension suitable for the second draft,
which uses a rotating cassette to
produce the final twisted square profile.
From the QRC unit, the produced
twisted square wire moves directly into
a modified Vitari NR300 straightening
and cutting unit that uses two
straightening roll panels, instead of the
traditional rotating spinner. The final
twisted square bar is then used for the
production of anti-skid grating panels.
With the same simplicity and efficiency,
the components can be changed in
order to produce different final wire
products to satisfy the different
requirements of the wire sector, eg
traditional reinforcement bars,
electro-welded mesh panels, etc.

Whitelegg Machines has specialised in the manufacture of
2D wire forming machines with automatic butt welding for
over 30 years.
CFMs are in use worldwide, bringing accuracy, repeatability
and precision to the production of wire and strip
components and sub-assemblies.
The CFM range incorporates advanced software, new bend
head and intuitive operator control, and offers
manufacturers even greater speed and reliability.
With the addition of a 16mm version, using the latest
technologies, Whitelegg has added to the versatility of the
CFM range.
Now with all servo operation and touchscreen industrial PC
running the advanced ‘Allform 4’ software package, the
CFM is able to produce highly accurate and consistent parts
with or without automatic butt welding. Wire or strip is taken
from the coil, straightened and then pulled through a highly
accurate feed system to the freely programmable bend
head.
A huge variety of shapes are possible and, if required, the
wire ends can be automatically butt welded. Thus squares,
rectangles, ovals and rings can be manufactured complete,
without the need for ancillary operations.
CFM machines are fitted with remote access capabilities
allowing engineers on-line access to the machine so
software updates, for example, can be easily and effectively
introduced.
