Versatile wire and cable handling systems for numerous applications

SV 410 D type NPS double spooler
Wire and cable machinery developed by Maschinenfabrik Niehoff covers nearly all operations which are necessary for the production of non-ferrous wires and special cables.
The product range includes pay-off and take-up systems adapted to the particular requirements of each production step. Typical examples of the take-up systems range are the WF type barrel coilers and the WSV static coilers for non-stop operation inline with wire production lines, the Bongard STN coilers for inline operation behind a galvanic plant, the compact S type spoolers which are suitable as take-up systems for multiwire drawing lines, and the Niehoff Package System (NPS).
The WF type automatic down coilers built in three sizes for wire diameters of 0.8 to 4.5 mm can be easily connected to all makes of rod breakdown machine and are suitable for use with barrels, baskets, stems and single use cardboard barrels. The container change can be fully automatic, which means that the WF type coilers are also suitable for unattended production.
A variable wire traverse (rosette pattern laying) guarantees optimum wire positioning and trouble-free downstream processing even after long hauls. A vibrating device ensures high filling weights.
The WSV type vertical static coilers wind the wire around a stationary spool by a rotating flyer bell. A cylindrical or conical wire laying pattern can be preselected via freely programmable control (PLC). The machines can be automated to a customized level of automation due to variable design of spool conveyor or transportation systems. Both types of coilers can work with a maximum production speed of 35 m/s.
For nearly ten years, the Bongard range of coilers for plated and bare conductors has been further developed by Niehoff. The coilers of the STN-650/800-TT series main application is for inline operation behind a galvanic plant. They are suitable for tin, silver and nickel plated copper wires with a wire diameter range from 1.00 up to 3.5 mm for both soft and hard wire.
The TW barrel coilers are designed for non-stop operation inline with intermediate wire production lines and suitable for use with barrels, stems and single use cardboard barrels. A variable wire traverse (rosette pattern laying) guarantees optimum wire positioning and trouble-free further processing even after long hauls. The adjustable falling height ensures a safe fine wire positioning in the barrel. The TW 480 model is designed for single wire diameters of 0.4...1.8 mm (Cu) and a maximum production speed of 36 m/s.
The most versatile method for spooling offer dynamic spoolers which wind the wire onto a spool rotating around its own axis in a horizontal position. A compact design, hydraulic lifting table for loading and unloading the spools and an automatic traverse system make these systems very user-friendly and provide the highest quality of the package. Niehoff builds a series of automatic single and double spoolers. The electric equipment with independent PLC suits for flexible integration of the spoolers in all lines.
Another example of Niehoff’s take up systems range is the Niehoff Package System (NPS), an efficient, safe and economical handling system for primary automotive cables as well as bunched wires, strands, conductors and cables. It comprises the SV type spoolers which use a patented wire-laying algorithm and collapsible multiway ABS plastic spools made in various sizes which offer a secure, stable and tangle free package both when full or partially empty and enable highest cable pay-off speeds into downstream processes.
The SV 410 D type double spooler shown at the wire 2012 trade fair is designed for the non-stop production of NPS packages and when installed behind an extrusion line is capable of spooling automotive primary cable at a speed of up to 1,500 m/min. This spooler is capable of accommodating all NPS 400 multiway spools with a traverse width of 100 to 400 mm without the need of exchanging pintles or spool take-up parts thus reducing set-up and changeover times.
