Cortinovis Machinery produces the
Conotorsion machine, based on
the single twist method of work.
Conotorsion can provide improved
quality on larger and rigid cable con-
structions, due to shallower bending
angles. In-line taping and binding
heads and wire payoffs can be used
for applying armouring, screening,
taping and binding.
The Cortinovis Machinery Conotorsion
features the high speed of the single
twist process, up to double that of
comparable drum twisters. It can
produce rigid and large diameter
cables, due to the very soft deviation
that is characteristic of this rotor design
and the optional double capstan.
Conotorsion high-speed machines can
be used for laying-up of control and
instrumentation cables, pairs, three
cores, and quads.
Conotorsion
will
accommodate
bobbins fitted between pintles from
1,000mm, 1,250mm 1,600mm and
2,200mm. The direct pull has digital
speed control.
Conotorsion can be used with all types
of payoffs, with or without back twist,
and bobbins driven with AC motors or
with mechanical or pneumatic brakes.
Conotorsion machines are available for
wire armouring and screening, for
payoff bobbins and take-up bobbins of
1,000mm to 2,200mm. The wires
payoff range includes stem packs with
copper, aluminium or steel wires.
For armouring and screening, one
Conotorsion payoff rotates synchro-
nised with a Conotorsion take-up, and
rewinds the cable put in rotation. In the
take-up, as an option, an integral
double capstan can be installed to
allow higher tension in take-up.
On this cable, wires from static payoffs
can be applied for making copper or
aluminium screens or steel wire
armouring. Conotorsion lines frequently
make both screening-armouring and
lying up of insulated cores for control
instrumentation cables.
The simple process allows a wide
range of payoffs for wires from coils,
packs or bobbins, according to the
process requirement.
The stationary line of wires allows the
easy application of wire straighteners.
On the line, a wide range of taping
heads can be inserted.
