Abstract

A method of manufacturing a cable with an electrical and/or optical transmission element containing core, which is surrounded by a cover of insulation material is indicated. Generated on the outer side of the cable on its entire length is at least one in the axial direction running strip composed of insulation material, which has a different color than the cover has. The material of the cover and the strip are applied by means of an extruder through co-extrusion simultaneously on the core of the cable so that the material of the strips is integrated into the material of the cover. The material of the cover and strips are applied by means of an extruder which has an inner flow channel and one surrounding all-around outer flow channel which merge. In the outer flow channel is arranged an all-around existing barrier constructed as a ring, that has at least one passage for the required material for a strip. The material of the strips is with pressure forced through the passage and pushed or pressed in the inner flow channel, through which the material for the cover is guided, as a result of which the material of the strips is imprinted or pressed into the material of the cover and thereby is tightly bound with the same or anchored in the same.
