    • 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.
    • 示出了由绝缘材料的盖包围的包含芯和/或光传输元件的电缆的制造方法。 在电缆的外侧沿其整个长度产生的至少一个在由绝缘材料构成的轴向方向行走条上,其具有与盖不同的颜色。 覆盖物和带材的材料通过挤出机通过共挤出同时施加在电缆的芯上,使得条的材料被整合到盖的材料中。 覆盖物和条带的材料通过挤出机施加,所述挤出机具有内部流动通道和一个围绕着的全周围外部流动通道,其合并。 在外部流动通道中布置有构造为环的全面存在的障碍物,其具有至少一个用于条带的所需材料的通道。 条带的材料是强制通过通道的压力,并被推压或挤压在内部流动通道中,用于盖子的材料被引导通过,导致条带的材料被压印或压入材料 盖子并因此与相同或固定在一起的紧密结合。
