Planetary (cage) stranders feature a compact design for configurations up to specified bobbin sizes or numbers of bobbins. This enables high operating speeds, low power losses, and simplified machine maintenance. Large planetary stranding cages are supported by heavy-duty lower bearings. The cages are designed to accommodate bobbins with flange diameters ranging from 315 to 2,800 mm and weighing up to 40 tonnes. Bobbin braking systems are engineered to meet the specific requirements of each application. Through various systems, CSM METALURJI provides tension measurement and display for wires or strands, operator adjustment of tension from the machine control desk, and automatic tension control.

Drive Technology

Individually configured drives cover an exceptionally wide range of lay lengths. Modern digital control technology enables infinitely variable and repeatable lay lengths to be set from the control desk. The back-twist drive provides variable back twist ranging from 65% to 135%. The use of a specially designed speed-modulated gearbox enables high back-twist torque to be transmitted. Different degrees of back twist can be applied within a single cage. Different cages within the same machine can be controlled with infinitely variable settings relative to one another.

A dedicated loading drive rotates the cage into position and stops it at each loading position.
