❍ Frigeco’s TA rod breakdown machine

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. 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. Swellable yarns for power cable

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.

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 • • • • • •

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.
