Zero slip breakdown
To tackle the demands of lower
production costs, improved machine
performance and finished wire qua-
lity, Frigeco (a division of Mario
Frigerio) has further developed its TA
copper and aluminium rod breakdown
machine with zero slip.
Conventional slip breakdown machines
can cause longitudinal friction – by the
wire sliding on the capstan – and axial
friction, as the wire moves from wrap
to wrap on the capstan itself. Frigeco’s
TA rod breakdown machine avoids
friction between wire laps and between
wire and the capstan. An independent
AC motor for each drawing block, with
dancer synchronisation of the wire/
capstan speed, eliminates the longi-
tudinal slipping problem and avoids
longitudinal wire scratches.
In each drawing block wire is wound
to a double capstan. The first pulling
capstan is motor driven while the
second idle capstan is out of centre
with respect to the first.
The idle capstan prevents side sliding
and drafting and avoids axial wire
scratches.
To prevent dangerous wire yielding
the machine is also supplied with
large diameter pulling and idle
capstans, while a high-pressure
lubricant die holder and efficient wire
cooling help to achieve high
production speeds.
Frigeco believes that the many advan-
tages of using the zero slip TA rod
breakdown machine include:
Reduced wire breaks when •
produced wire is re-drawn
The machine is adaptable to •
most drawing ranges and wire
elongations, with inlet diameter
from 8mm to 10mm and outlet
diameter of 0.8mm to 9mm
Reduced energy consumption •
The absence of slippage mini- •
mises pulling capstan wear,
resulting in low maintenance
costs and reduced downtime
Low noise, less than 80dBA •
Unused motors are switched off •

GarnTec is a worldwide supplier to
the cable industry.
The company has recently deve-
loped a range of water-swellable
yarns, QE-SC, especially for power
cables. The yarns are designed to
offer the highest swelling capability
for longitudinal waterblocking.
Yarns from 1.5mm to 8mm diameter
are also used as a construction
element.
Swellable and separating tapes are
available for all types of cables.
Tapes are available in a range of
spool sizes, from 10kg spools up to
wooden drums of over 100kg.
