NPS with increased production speed

NIEHOFF manufactures machines which cover nearly all processes of wire and cable production and handling. The Niehoff Package System NPS is an efficient, safe and economical handling system for automotive wires. It consists of specially developed SV type spoolers and collapsible ABS plastic multi-way spools. At the latest Niehoff in-house exhibition at the headquarters in Schwabach, Germany, held immediately after the wire 2016 trade fair, the latest version of the SV 402.D type double spooler was on display. Niehoff engineers have achieved a 20 per cent increase in production speed, which is now up to 1,800m/min with original NPS spools. One more advantage of the system is that original NPS spools provide highest production safety and a very safe operation. The SV spoolers are foreseen to operate in line with extrusion lines. They spool the insulated wire coming from there with a particular conical wire laying technology onto the spools. Changeover from full to empty spools is carried out at full production speed, allowing for non-stop production and enabling the highest cable pay-off speeds into the downstream processes. The Niehoff standard range consists of The PWC-S system performs wire cleaning and polishing in-line with a wire drawing machine at 6 to 12m/s (1,200 to 2,400ft/min). Exceptional cleanliness obtained permits wire direct brass coating, copper coating, galvanising and wire cleaning prior to heat treatment and coating applications including patenting, annealing, painting, plastic coating, etc. The system incorporates new technology that enables normal cold plant water to be converted into a unique cleaning medium, generating high pressure wetting/contaminants extreme pressure extrusion/ hydrodynamic cavitations displace- ment, and contaminants flush out,

six NPS spools in different sizes. Empty NPS multi-way spools can be fully dismantled and nested into each other. Dismantled spools take up only a third of the space of comparable conventional spools and require much less return shipping space than traditional spools. For applications where no regular spool exchange takes place, the NPS 400 one-way spool is offered. The successful NPS concept has resulted in a worldwide pool of more than three million NPS multi-way spools, all compatible with each other. No matter which spools are returned, their components always fit together. To protect the NPS spools from foreign spools which are not compatible with the NPS and are a safety risk, Niehoff has protected the system for a long time. ❍ The SV 402.D type double spooler from Niehoff

One of the measures is an RFID transponder system with which all new original NPS multi-way spools are equipped. By this transponder NPS users can identify if a spool belongs to the system and is compatible with it or not. The transponder also simplifies spool labelling: as the spool identification is stored in RFID, no label is needed. The NPS is claimed to be the world’s only packaging system for automotive wires made of copper, copper alloys and aluminium, which allows trouble-free and tangle-free paying-off at highest speeds. Even signal cables made of copper alloys with a cross-section of 0.13mm² can be processed without any problems. Maschinenfabrik Niehoff & Co KG – Germany Website : www.niehoff.de removes lubricant residue from the base material and is particularly recommended for cleaning applications with wires drawn upon severe conditions resulting in increased heat and burned lubricant tightly bound to the wire surface and embedded in micro-cavities. For decorative mirror reflective wire applications, the system can be used with an emulsion including a new rust preventive additive diluted at 3-5% concentration. The PWC-S unit is compact and can be easily installed on the finishing/last block of a wire drawing machine. Decalub – France Website : www.decalub.com
