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. Zollern GmbH & Co KG – Germany Website : www.zollern.com 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 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. WTM Srl – Italy Website : www.wtmachinery.com understands completely 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. Zollern Stand: 12C71
