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.

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.

DCCD process features: • Eliminates acid, borax and precoatings • Zero energy consumption • Direct drawing from bare rod with no speed limitation, for H/C and L/C • New Lubricant Viscosity Control provides exceptionally adherent coating • Adjustable lubricant residual • Zero lubricant waste • Recommended for severe drawing applications (spring, rope, bead, CO 2 welding, PC strand, plating quality) • H/C wire drawn at 18 m/s (3600 ft/min) • Up to 8 times longer die life • Exiting wire temp. 45°C (113°F) • Greatly improved wire ductility
