Wire & Cable ASIA – November/December 2016
Technologynews
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
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.
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.

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,
used to clean drawn wire at
high-speed in a completely green
application, providing a glossy wire
finish in plating quality.
The PWC-S system effectively
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.
