At the wire South America 2015 trade fair, Maschinenfabrik Niehoff and Niehoff-Herborn Máquinas Ltda. (NHM), its Brazilian subsidiary, will show an MMH 121 type multiwire drawing machine, an SNH 801 type spooler and a D 631 type double-twist bunching machine with ARP 630 pay-off (booth 612 / 713). All machines were built by NHM under Niehoff licence.


The exhibits

The multiwire drawing machine MMH 121 is designed to draw simultaneously 28 wires with a final diameter of 0,51 ... 0,20 mm (24 ... 32 AWG) at a maximum production speed of 36 m/s (7086 fpm). The wires can be processed to intermediate multiwire bundles.Typical wires which can be produced on the MMH type drawing lines are copper wires for highly flexible cables, automotive cables, battery cables and installation cables. The machines are also suitable for aluminum wires, wires made from copper and aluminum alloys and from other non-ferrous metals.

The wires drawn on such lines have homogeneous physical properties along their whole length and exceed the highest processing requirements. Because of their modular design Niehoff multiwire drawing lines can be adapted to different customer requirements with great flexibility. Meanwhile, more than 1,100 MMH lines are working world-wide.

The D 631 type double-twist bunching machine is foreseen to produce strands with 0.09 to 6.00 mm² (27 ½ ... 9 ½ AWG) cross section and a steplessly variable lay length of 6 to 100 mm. The maximum number of twists is 6,500 twists/min, the maximum production speed 300 m/min. A special feature is the patented opto-electronic NBAT system (Niehoff Bunching Automatic Traverse), which allows spools to be perfectly spooled. Spooled wire can then be payed-off tangle-free at extremely high speeds with no damage. Other features include the service proven energy-saving single bow (ECO-Bow) design, the contactless transmission of machine data within the machine and the NMS touch-screen display with color user interface.

The ARP 630 type pay-off completes the portfolio for the production of strands. By clamping the spool with the help of pintles spool loading becomes fast and easy. Spools with various bore diameters can be used, and as an option particular spool lifting tables are available too.



At the Niehoff booth, a complete island booth, will be present: Bühler Würz Kaltwalztechnik (cold rolling mills), Strecker (wire welding machines), HFSAB (lead extruders and cable repair and recovery systems) and Reber Systematik (filtration systems).
