ABSTRACT:
A method of and a device for adjusting the capacity and the diameter of an electric conductor provided with an insulation coating of foamed plastics material in an extruder press. The press is provided with an adjustably rotating feed screw and adjustable heating means. The deviation of the capacity of the insulated conductor from a preset capacity and the deviation of the diameter of said conductor from a preset diameter are measured at the path of movement of the conductor. The rotation speed of said screw is adjusted in response to said capacity deviation and said diameter deviation and the temperature of said heating means is also adjusted in response to said capacity variation and said diameter deviation in order to correct said deviations.
