Wire & Cable ASIA – September/October 2008 54
The high-speed bow type machine is
suitable for a wide range of products
with the back twist process giving high
quality results.
Cortinovis bow stranders use
components made from the most
modern materials, such as carbon fibre
for the bows, tungsten carbide for
bushes and hardened steel for rollers.
Set up is by control panel, and an
electro-mechanical or pneumatic self-
compensated brake controls tension of
the cores.
Safe use is maintained by control of
bearing temperatures and vibration and
the machine is protected with a
pneumatically controlled soundproof
cover, inside fans and lights.
High productivity bow type laying-up
machines can be used for round and
straight sectoral insulated cores for low
voltage cable.
The machine can be
loaded from the top by
overhead crane or with
a semi-automatic side
trolley, which avoids the
use of bridge cranes and
dramatically reduces the
total loading time of the
line.
The uses of bow type
stranding and laying-up
machines for the cables
industry include:
Stranding of con- •
ductors made with
copper, aluminium,
aluminium alloy, alu-
minium steel reinforced or
supported
Laying-up of 2–7 round insulated •
cores for low and medium voltage
Laying-up of 2–7 straight sector •
shaped insulated cores, with the
rotating cradles version
Application of fillers and tapes •
For the steel industry the machines are
used to produce steel strands.
