Monotorsion technology

Cortinovis Machinery’s Monotorsion armouring and screening machine ▲ ▲

Also available are monotorsion laying-up machines for take-up bobbins of 630mm to 1,600mm. The high-speed single twist mono- torsion can be used for laying-up insulated cores from a variety of pay-offs. In-line taping and binding heads can be used for applying screening, taping and binding. The monotorsion machines can be used for laying-up of control and instrumentation cables, pairs, three cores, or quads.

Cutter power has been increased and they are now capable of cutting through even stronger armouring. Petig’s hydraulic cable cutters are usually driven by compact hydraulic units, with a flow rate of between 1.75 l/min and 11.16 l/min. According to the type of cutter, the working pressure varies between 250 and 600 bar. It is also possible to activate the cutters with hydraulic hand- or foot-pumps. The new HKS 8 has an additional pneumatic spring for easier opening and closing of the cutter jaws. Friedrich Petig GmbH – Germany Fax : +49 2181 73108 Email : info@petig.com Website : www.petig.com

Cortinovis produces Monotorsion laying up, wire armouring and screening machines with payoff and take-up bobbins of 630mm to 1,600mm. A rotating monotorsion payoff and rotating take-up rewind the cable, putting the cable in rotation. The line is completed with payoffs from coils or stem packs of copper, aluminium or steel wires and all stationary payoffs for insulated cores. and screening system can be used to apply copper or aluminium screening or steel armouring wires; the same line, with suitable pay offs, can make laying–up of control and instrumentation cables. The stationary way of wires allows the easy application of wire straighteners, and a wide range of taping heads can be inserted within the line. Machinery The Monotorsion armouring Petig’s cutter range was recently extended with the new HKS 8, designed for cutting submarine cables up to 240mm diameter, depending on the armouring. As with the other large cutters in Petig’s range, the cutters are available with either a single– or a double–acting hydraulic cylinder. Cutters with a double–acting cylinder have the advantage that they can always be opened hydraulically, even if, following a long period of use with the blades becoming blunt, a stranded conductor or part of the armouring becomes jammed between the blades. The larger cutters, which cut diameters of up to 85mm and 110mm, are now made of solid aluminium, making them
