Cutting cables
the Petig way . . .
For many years Petig has been among
the leaders in the field of hydraulic
cable cutters.
Long before the hydrocut steel cutter
made its appearance in the wire rod
mills of the world, the first cable and
wire rope cutters had been presented
to Petig customers. Since then a
vast family of hydraulic cable cutters
has resulted. The cutters, which are
made in eight sizes, have differing
capacities.
The smallest shear cuts to a maximum
diameter of 16mm while the largest
shear copes with a maximum of
225mm. All the larger cable cutters are
available with both single and double-
action hydraulic cylinders.
The double-action cylinder has the
advantage that if, following a long
period of use, a strand or integral part
of the sheathing should jam between
the blades as a result of wear of the
blades, the latter can be opened using
hydraulic power.
The larger cutters, which cut up to
85mm and 110mm, are now made of
solid aluminium. This saves about 35%
of the weight, and gives an increase
in the cutter power because of this
design change.
The hydraulic cable cutters are usually
driven by compact hydraulic units,
with a flow rate between 1.75l/min
and 11.6 l/min. Depending on the type
of cutter, the working pressure varies
between 250 and 600 bar.
It is also possible to activate the cutter
with hydraulic hand or foot pumps.
Most recent Petig developments are the
HKS5 and HKS6 series made of solid
aluminium. This significantly improves
manageability of the cutter through a
weight reduction of up to 35%.

New automatic spool
winding line
PS Costruzioni Meccaniche has
launched a new, improved double head
fully automatic spool winding line. The
enhanced features are most noticeable
in regard to the restart time between
one wound spool and the next one.
While the first spooling head is winding
the cable, the second head has com-
pleted the winding cycle, enabling the
final spool to automatically proceed to
the palletising area.
The PS 200/6/B enables customers to
double normal machine output, thanks
to the two winding heads working
at the same time. This machine can
accommodate approximately 200
cardboard, aluminium, plastic, plywood
and wooden spools which are located
in two separate stores. The spool
ranges are flange outer diameter from
100mm (3.94") to 200mm (7.88") and
flange width from 50mm (1.97") to
190mm (7.49").
PS 200/6/B process specifications are:
Bore centreing (to start the winding
operation);
Cable layer on layer winding;
cable measuring accuracy ±0.1%;
Spark tester cable insulation tests
Pneumatic and fast cable cutting;

•
End-product packaging by polye-
thylene film;
Division between end-products
with insulation defects and correct
end-products;
Labelling;
Palletising (a Cartesian axis
palletiser);
Pallet wrapping.
The machine can produce more than
four spools of 100m (328.08ft) per
minute while cable sections can vary
from 0.65-6.53mm2 (AWG from 19-to 9).

The wireguide comes with CNC digital
technology, and special CNC software
helps to obtain perfect winding results.
An in-line cable diameter detector can
be included which can correct any cable
diameter modification in real time.
