Planetary wire and cable machines

Cortinovis Machinery produces stranding, armouring and laying-up machines with planetary gearing, for bobbins up to 630mm supported by bearings or, on under-rollers, up to 3,000mm. The field proven planetary machine can be used in many different applications: Armouring of energy and communication cable with steel wires • Stranding of steel wires to produce strand • Closing of steel strands to produce ropes • The machine, which is supported on bearings, is of a modern design, for bobbins up to 630mm. The under-rollers design is used when the size of the cage requires a distributed system of supports. Different technical solutions are applied on the basic machine, but always with the target of robust, reliable and operator-friendly construction.

❍ Cortinovis Machinery’s planetary design armouring and stranding machine

Total back-twist is provided by the simple and reliable detorsion ring; it is also possible to work in torsion, as typical for armouring with steel flat wires. Partial back-twist is also possible, using a separate motor and transmission with pulleys and belts, for the production of strands and ropes.

The modular design allows for different sizes and numbers of bobbins:

Planetary 01: The under-roller cage can handle larger sized bobbins, from • 710mm up to 3,000mm diameter. The under-rollers are automatically lubricated, made of the finest quality material and designed for years of trouble-free operation Planetary 02: The bearing cage is a one-piece welded fabrication of steel • plates and tubes, annealed, machined and balanced and supported by large encircling bearings. The advantage of this design is the rigid rotor, reliable supports made with roll bearings, easy alignment, and no maintenance of rollers
