An arrangement for making a fluid-tight cable, as well as a method and a cable obtained thereby, includes a tubular injection device (21) through which passes a cable core (9) wrapped in a permeable tape. The device which has an adjustable chamber (W) disposed around the cable core is able to perform a reciprocating movement. During the forward stroke the device travels with the cable and a water blocking material is injected into the cable core to fill the interstices between the conductors thereof. During the backward stroke when the device returns to its initial position the injection is stopped and the material present in the chamber is smeared out over the tape. |
