ABSTRACT:
A system for controlling the outer diameter of a strand, particularly of a cable or the like including a measuring device for measuring the outer diameter of the strand of plastic material emerging from the extruder. The signal of the measuring device is fed to a comparator which compares it with a reference diameter and generates a difference signal. A control unit receives the difference signal to control the rotational speed of the extruder and/or the speed by which the strand emerges from the extruder. A computing stage is connected to the control unit which generates a comparison signal modulated by the actual diameter signal and fed to the control unit.
