BMV type braiders can be equipped with three patented systems. The braiding speed of a BMV 24 type model can be automatically accelerated from 110 rpm to a maximum value of 130 rpm, while the BMV 16 (16-spool carrier version) can accelerate from 175 to 200 rpm. The result is a 10 per cent higher braiding performance. At the same time, the frequency of lubrication is reduced, depending on the slideway temperature. Less lubricant is used and less oil contamination occurs on the braids. Using Niehoff’s Wire Tension Control System, all braiding wires – from full to empty braiding bobbin – can be applied to the product to be braided under uniform tension. The Coverage Control System ensures a constant braiding coverage ratio at the set value. Since only the necessary amount of braiding wire is applied, up to 10 per cent braiding material savings can be achieved. The BMV type braiders can be applied for a wide application range. They are designed for processing bare or plated round or flat wires made from copper, aluminium or stainless steel, and also artificial yarn and fibres. The braiders can be used to manufacture cable screenings, copper braids, hollow braids, stranded braids, textile braids and steel wire braids with different braid patterns.

NMC builds, among others, MMH type multi-wire drawing lines under Niehoff licence for the Chinese market. These lines consist of components built and supplied by the Niehoff headquarters in Germany (the mechanics of the MMH drawing machine), and components built by NMC – the annealer, the switch cabinet and the spooling system. NMC assembles the components and carries out test runs. After successful testing, the line is delivered to the customer, where NMC technicians are responsible for installation and start-up. The main advantages of the MMH 121 + RM 201 line that will be on display are its compact design, high productivity and a low wire break rate. The resistance annealer works with the two-/three-zone annealing, which can be selected with or without wire reheating. The results are optimum wire drying and an economical use of energy for larger wire sizes. The D 632 type double twist bunching machine, also built by NMC under Niehoff licence, is characterised by high productivity. The single-bow design in combination with the energy-saving Eco-Bow installed in this machine ensures energy savings compared with conventional bunching machines. Further features are an electric lay length adjustment (changing lay-length without changing gears) and constant tension control of the strands from empty to full spool. As the D 632 produces bunches with very tight tolerances, only the required copper cross section is generated, resulting in material and operational savings. Owing to the adjustable and controlled wire tension – regardless of the spool filling – and the integrated opto-electronic NBAT (Niehoff Bunching Automatic Traverse) system, the spools are filled with a precise winding pattern, allowing the bunches to be paid off tangle-free, even at high speeds. The BMV 24 type vertical lever-arm rotary braiding machine, equipped with 24 bobbin carriers, features infinitely adjustable electronic control of line speed and braiding pitch as well as an automatic central lubrication system. Multiple monitoring systems enable unattended operation over long periods of time. D 632 type double twist bunching machine

It sells worldwide, either directly or through its network of agents, distributors and branch companies – Pan Chemicals Bosphorus in Turkey and Pan Chemicals Americas in Mexico.
