Maschinenfabrik Niehoff and its subsidiary Niehoff Endex North America, Inc. (NENA) will be exhibiting at the Interwire 2017 trade fair on booth 841
- an MMH 121 + RM 201 multiwire drawing line,
- a D 801 type double-twist bunching machine with an ARH 800 pay-off,
- and a BMV 16 braiding machine.
In addition, the offerings of the After Sales Service and the Niehoff Original+ components will be showcased at the booth as well.
Description of the exhibits
The multiwire drawing machine type MMH 121 is designed to draw simultaneously 24 wires with a finished diameter range of 0.16 mm (AWG 34) to 0.51 mm (AWG 24). The machine is combined with an inline annealer type RM 201 and can operate at speeds up to 40 m/s (7874 fpm). As the MMH machines are based on a modular principle, they can be built suitable for wires made from copper, aluminum, their alloys or other non-ferrous metals and ideally adapted to the specific customers' requirements.
The wires drawn on these machines exceed the most demanding specifications and processing requirements as far as physical properties and can be processed to multiwire bundles with outstanding characteristics. To date, more than 1,500 MMH lines are in operation world-wide.
The D 801 type double twist machine is designed for bunching plated and bare wires or twisting insulated wires. The machine can be used to produce strands with 0.25 to 16.0 mm2 (23...6 AWG) cross section and an infinitely variable lay length of 15 to 160 mm (0.6...6.3"). Insulated wire can be stranded up to an OD of 7.5 mm (0.3"). The maximum line speed is up to 5,000 tpm or 300 m/min.Other characteristics are the field proven energy-saving single bow (ECO-Bow) design, the non-contact data transmission within the machine and the NMI touch-screen display with color user interface and simplified navigation structure. The machine is combined with an ARH 800 type tangential pay-off with separate drive.
The 16-carrier lever arm rotary braiding machine BMV 16 can process bare or plated copper wire, aluminum wire and stainless steel wire with single-wire diameters ranging from 0.05 to 0.3 mm (40 ... 28 1/2 AWG) as well as artificial yarn and fibers. This machine features an infinitely adjustable electronic control of line speed and braiding pitch as well as an automatic central lubrication system. The machines can be combined with different kinds of taping devices. Upon customer request an automatic empty bobbin detection system can be integrated which on the one hand stops the machine before a braiding bobbin is empty, and on the other hand keeps the residual wire on the braiding spool to a minimum. By means of integrated and optionally available quality assurance systems, BMV braiders can operate unattended for extended periods and without frequent operator intervention.
The machine at the stand is equipped with a BAS 800 take-up and pay-off unit for spools with a flange diameter of up to 800 mm.
