Multiple tasking from Eurolls

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 ❍ The Quick Rolling Concept from Eurolls

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. Eurolls – Italy Website : www.eurolls.com

Advanced software offers greater speed and reliability

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.

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
