Cortinovis Machinery produces
Monotorsion laying up, wire armouring
and screening machines with payoff and
take-up bobbins of 630mm to 1,600mm.
A rotating monotorsion payoff and
rotating take-up rewind the cable, putting
the cable in rotation. The line is completed
with payoffs from coils or stem packs of
copper, aluminium or steel wires and all
stationary payoffs for insulated cores.
The Monotorsion armouring and
screening system can be used to apply
copper or aluminium screening or steel
armouring wires; the same line, with
suitable pay offs, can make laying–up
of control and instrumentation cables.
The stationary way of wires allows the
easy application of wire straighteners,
and a wide range of taping heads can be
inserted within the line.
Also available are monotorsion laying-up
machines for take-up bobbins of 630mm
to 1,600mm.
The high-speed single twist mono-
torsion can be used for laying-up
insulated cores from a variety of pay-offs.
In-line taping and binding heads can be
used for applying screening, taping and
binding.
The monotorsion machines can be
used for laying-up of control and
instrumentation cables, pairs, three cores,
or quads.

Cortinovis Machinery’s Monotorsion armouring and screening machine ▲ ▲
Petig’s cutter range was recently
extended with the new HKS 8, designed
for cutting submarine cables up to
240mm diameter, depending on the
armouring.
As with the other large cutters in Petig’s
range, the cutters are available with
either a single– or a double–acting
hydraulic cylinder. Cutters with a
double–acting cylinder have the
advantage that they can always be
opened hydraulically, even if, following
a long period of use with the blades
becoming blunt, a stranded conductor
or part of the armouring becomes
jammed between the blades.
The larger cutters, which cut diameters
of up to 85mm and 110mm, are now
made of solid aluminium, making them
35% lighter. Cutter power has been
increased and they are now capable
of cutting through even stronger
armouring.
Petig’s hydraulic cable cutters are
usually driven by compact hydraulic
units, with a flow rate of between 1.75
l/min and 11.16 l/min. According to the
type of cutter, the working pressure
varies between 250 and 600 bar. It is
also possible to activate the cutters with
hydraulic hand- or foot-pumps. The
new HKS 8 has an additional pneumatic
spring for easier opening and closing of
the cutter jaws.
