A method and apparatus for extruding a plastic rod having helical slots in its external surface comprises the use of a die including a relieved exit end face, resulting in a more uniform drag on the plastic melt. Plastic rods so formed are used in slotted core type optical fiber telecommunication cables. The die includes internal channels which form peripheral ribs on the plastic rod. The channels may follow either a helical or a straight path.

Une méthode et un appareil pour l'extrusion d'une tige en plastique comportant des fentes hélicoïdales sur sa surface extérieure consiste à utiliser une filière comportant une sortie à section réduite, qui produit une traînée plus uniforme sur le plastique en fusion. Les tiges en plastique ainsi formées sont utilisées dans les câbles de télécommunications à fibres optiques à coeur rainuré. La filière comporte des canaux internes qui forment des nervures périphériques sur la tige en plastique. Les canaux peuvent suivre une trajectoire hélicoïdale ou rectiligne.
