taping, armouring & sheathing of cables
Three times more production capacity
Pourtier - Gauder Group has developed three applications of its high-speed concentric armouring head to place one or two strips on
power cable or communication conductors up to 50mm in diameter.
The head enables the application of a
long length of strip without interruption
and minimises loading and unloading
operations. Thanks to the concentric
process, which gives less centrifugal force
than in a tangential process, the rotating
speed ranges from 600 up to 1,500 rpm.
The taping tension – controlled by dancer,
motors and drives – is very accurate.
The first application, the CAH670, applies
two tapes (steel or copper) onto the
cable while the second, the CAHL720-60,
is dedicated to apply pre-formed strip-
type aluminium or steel (lapped cable).
Both models can be equipped with an
integrated spool-manufacturing unit for
the rolling of the spool from standard pads,
while the armouring head is taping. No
handling of the spools is required as they
are rolled directly on the machine. The
loading operation is made without cutting
the cable.
The third type, CAHi900-60, is specially designed to produce interlocking cable with aluminium or steel strip at high speed for a
36" spool (available for 2, 4 and 5" diameter).
The company has also designed a solution for steel wire armouring on small cables (diameter up to 20mm), the TEC 630-SWA
multiwire concentric head achieving at least 2.5 times the productivity with
conventional, single twist machines.

RG’s tapeformer
The RG Tapeformer is used by cable manufacturers to fold a variety of insulating
materials around cable cores before entering the final jacketing stage.
They can be used with
many insulating tapes
including Mylar, paper
and metalised foils,
and can insulate a wide
range of cables including
LAN, power, telephone,
communication, coaxial
and automotive cable. The
Tapeformer is positioned
just before the extruder
head and guarantees
precision folds. With
an extensive selection
of models and folding
profiles, the Tapeformer is
manufactured to the user’s
exact requirements.
RG Attachments is looking to further extend the range of profiles offered by its
Tapeformer series, based on feedback received from customers and visitors to its stand
at wire 2008.
