Zusammenfassung:A device for encasing a rope-like strand containing one or more light waveguides, which device includes two extruders situated one after the other characterized by a fluid cooling device positioned between the two extruders for applying a cooling fluid to the external surface of a first layer applied by the first extruder to cool it prior to extruding a second layer thereon. The cooling device enables increasing the rate of travel of the rope-like strand during the extruding operation.
