The employment of wire and cable in
the US has been steadily increasing,
especially in the medical and electronic
markets. The application demand of
smaller and more compact product
designs has placed demands not only on
the suppliers of these two items but even
more so on products and the machines
that can process the base items into
ever more sophisticated products and
subassemblies.
Wire diameters of under a millimetre
(0.040") are increasingly being utilised
for applications in the medical and
electronic market places. The material
composition of the wire used in such
applications can be of very special alloys
or as in many medical applications, high
tensile stainless steel. The end products
or subassemblies made from these small
diameter wires require more advanced
processing and forming equipment.
TAK Enterprises, of Bristol, Connecticut,
USA, has been an innovator and
manufacturer of machines and systems
for the processing and forming of wire
and narrow strip type materials since
1981, and has recently been recognised
with lifetime achievement awards for this
work.
The newest product to be offered by TAK
that satisfies many of the demanding
needs of these small diameter
applications is the new “Programmable
Rotary Wire Straightener”. This system
is ideally suited to produce extremely
straight and precisely cut-to-length
wire pieces automatically. The system is
fully equipped and configured to take
standard DIN style spools of wire, pay the
wire out under controlled tension, rotary
straighten the wire, feed to whatever
length desired, cut the wire to length
without hindering the wire feed, provide
a square end burr-free cut, and stack
finished wire pieces for collection. The
system can either continuously produce
cut pieces until the material runs out,
produce pieces based on a quantity limit,
or provide batch quantities of a total
production quantity on command.
The TAK PRWS (programmable rotary
wire straightener) is designed to run
operator free from pre-programmed
settings entered into the controller. These
“programmed” settings include:
• Payout tension value
• Wire feed speed
• Clockwise rotating arbor speed
• Counter-clockwise rotating arbor speed
• Cut length
• Quantity
In addition to system monitoring sensors
for such things as out of wire and low air
pressure, the system design allows for
the integration and control of additional
devices that might include eddy current
checking, mechanical sorting, or even
wire marking devices.
