VERFAHREN ZUR HERSTELLUNG EINES OPTISCHEN KABELS.

摘要

An optical cable consisting of a central pull element with six stranded optical fibres, surrounded by a sheath of e.g. Kelvov (RTM) rovings or glass fibres and an outer sheath is produced by pulling the core (3) by a withdrawal pulley over a brake disc through the extruder (4) for the outer sheath. After cooling in a trough a pair of endless crawler chains pushes the sheath towards the pulley and upsets (compresses) it.
