Additionally, the D 631 allows a reduction in material costs because it produces strands with very tight tolerances, so only the minimum required copper cross-section is used. The NBAT system and the precise functioning of the machine enable one operator to control multiple machines at the same time. The D 631 is designed for strands with a cross section of 0.09 to 6mm 2 and a steplessly variable lay length of 6 to 100mm. The maximum number of twists is 6,500 per minute, while the maximum linear speed is 300m/min. The BMV 16 rotary braiding machine – the most recent version of Niehoff’s vertical lever arm rotary braiding machines – features three patented innovations. The 16-carrier machine can automatically increase the bobbin speed from 175 rpm to a maximum value of 200 rpm, and reduce the frequency of the lubrication intervals. The machine keeps the coverage ratio of the cable constant at the pre-set value, regardless of the changing diameter of the cable to be braided, making it possible to apply only as much braiding wire as necessary. Via the WTC (wire tension controlling) system and dancer position, the machine controls the wire tension of the braiding bobbins, from full to empty condition. All braiding wires are applied to the product to be braided with uniform tension. The result is a uniform braid along the whole length of the product. Such shieldings are particularly required for applications in the area of autonomous driving. Maschinenfabrik Niehoff GmbH & Co KG www.niehoff.de Focused the Numalliance Group creates and produces efficient solutions for wire, tube and flat stock forming. The company’s machines and automated cells are made in France, and also in the USA since the acquisition of the assets of Addition Manufacturing Technologies including Eaton Leonard, Addison McKee and Eagle machines. This new entity of the group, called AddEaton by Numalliance, completes the on the future, Numalliance SAS Stand: W1C07

Numalliance tube range with a supplier of bending and end forming tools. Numalliance has a worldwide presence, with employees located on each continent providing customers with price requests for machines and tooling, visits from sales representatives, and machine support by technical support engineers. At wire China the company will present its latest innovations in bending and end-forming technologies, such as intuitive, fast and flexible machines and automated cells that allow users to change their production more easily. A slip ring on many of the wire bending machines increases the production range of different parts. As electric mobility gains momentum, Numalliance engineers have been developing more efficient solutions for bending, twisting, cutting and peeling copper products such as hairpins or busbars. The new FPX bender is dedicated to busbar production, with easy programming, quick production changeover and multiple bending possibilities. The FPX is equipped with a belt feeder to avoid marks on the material. Complementary units such as punching, engraving and notching can be added easily, and a new cutting system offers a perfect angle cut, with stripping of the extremity. Numalliance, through its main trademarks – Silfax, Latour and Eaton Leonard – has been established in China for many years, with 480 machines deployed throughout the country. Customers come from a range of sectors, but the majority are in the automotive and aeronautics industries. Sales and technical support staff are based in Shanghai, allowing Numalliance to quickly provide response to customer requests.

➣➢➣ The system has all typical interfaces and is suited to closed-loop control (eg conductor preheater). One of the goals in designing the Easy-Wiretemp was to maintain performance and production stan- dards while reducing manufacturing cost. Lune CHF GmbH www.lune-chf.com

Maschinenfabrik Niehoff GmbH & Co KG Stand: W1F27

Maschinenfabrik Niehoff and Niehoff Machinery Changzhou Co, Ltd (NMC), Niehoff’s Chinese subsidiary, will display an MMH 121 + RM 201 multi-wire drawing line and a D 631 high-speed double-twist bunching machine (both built by NMC), and the latest version of a BMV 16 rotary braiding machine. The MMH 121 + RM 201 multi-wire drawing line was made by NMC under Niehoff licence. The mechanics of the drawing machine and all key components were supplied by the Niehoff headquarters in Germany. The drawing machine is designed to simultaneously draw 14 wires on one level and can work at a maximum speed of 35m/s. Features of the line include high productivity, a low wire break rate and energy saving operation. The MMH multi-wire drawing machines are designed for copper and aluminium wires, and built on a modular principle so they can be adapted to the specific tasks of the customer. Wires drawn on MMH machines show homogeneous characteristics and narrow-tolerance properties along their entire length. Wires can be processed to multi-wire bundles and are suited to final applications or downstream processing into strands, ropes or braids. The D 631 double-twist bunching machine was also built by NMC under Niehoff licence. Its features include high productivity, high-quality products and perfectly filled spools. The one-bow design and the installation of an Eco-Bow ensure energy savings compared to conventional bunching machines.
