    A method of and apparatus for making the cable core of a telecommunication cable water-tight in the longitudinal direction, in which a filling material having a base of petroleum jelly is heated to a temperature above the drop point, is supplied under pressure to a filling head (5), is divided into a number of jets distributed over the circumference of the cable core, is passed through the filling head (5) with simultaneous conversion of the static pressure into kinetic energy and is injected through the outer layer of the cable core into the heart of the cable core, in which a reconversion of the kinetic energy into static pressure is effected and all the interstices and gaps between the single wires of the cable core are filled with the filling material.

It consists of 1 GP3 inner tube 23 and a circumferential tube 24, the inner diameter of which is larger than the outer diameter of the inner tube 23. On the outer side of the inner tube there are two rings 25 and 26, and the inner side of the circumferential tube 24 installed liners 27 and 28. The inner diameter of the liners 27 and 28 and the outer diameters of the rings
    25 and 26 are chosen such that the rings fit snugly to the inserts. In the outer side of the ring 25 there are diametrically opposite grooves 29, each of which extends
    around the periphery of the ring, while in the wall of the circumferential tube 24 and insert 27 there are two diametrically opposed slots 30, each of which
    extends around a portion of the periphery of the circumferential tube 24 and the insert 27. When assembling the filling head 2. the rings 25 and 26 are inserted into the inserts 27 and 28 until the ring 24 is
    resist c in protrusion 31 of liner 27 and groove 29 will not be opposite the slots of Y. The inner tube 23 and the circumferential tube 24 are fixed against the relative axial movement along pe ;; (. 1 and the wire element. I2, KOTxipbii t passes through the slots 30 and enters the grooves 29. In the liners 27 and 28, you can see from the inner side 1: olyenes grooves 33 and 34, in which the sealing rings 35 and 36 are installed, respectively. On the outer side, two fastening brackets 37 are located 24 that are used to suspend the filling head 2 in the connector 1. In the circumferential pipe 24 and has an inlet 38, which is connected to the pipe 39, which is part of the pressure pipe 1 3. In the inner wall
    t: pipes 23 are made of a series of holes 40 (in this case, 4 holes), which are located in separate radial planes and at some distance from one another around the axis
    pipes. The annular space between the inner tube 23 and the circumferential tube 24 communicates through the opening 38, the pipe 39 and the discharge pipe 3 with the pump 4 and acts as
    iioHbautMiHoi camera Depyimsh, Cherel open-air 1 h 40 k, hms p 1 but new data is associated with the nickel of the inner tube 23 and this space acts on the 1st camera). 11th run} 1a the camera extends without any restriction from the o / i end to the other horse of the inner tube 23. The core of the cable 22, which should be processed, can pass through the lateral chamber with a large radial clearance, since the diameter d of the core of the cable less than the inner diameter D of the inner tube 23, and there are no grip elements, such as nozzles of the spinneret, etc. In the process of filling the cable core in the flow chamber, there is practically no pressure.
    The same inner tube is suitable for processing a series of cable cores having different diameters. If the cores of the cables to be machined have a diameter larger than the inner diameter D of the inner tube 23, an inner tube having a larger inner diameter D and, if necessary, a greater number of holes 40, should be used. Thus, the inner tube has the inner diameter can be used to blunt another row of different cable cores. In this way, with a very limited number of components, a whole variety of commercially available cables of various types can be processed.
     The filler die consists of a pipe 41, which is connected to a feed pipe 42, which forms part of a pressure pipe 12 leading from a feed tank. A coating layer is applied to the outer surface of the already filled cable core by means of filling strings. The filler supplied to the filling filler has a lower temperature than the filler temperature — which must be injected, i.e. temperature below condensing temperature. The inner diameter of the pipe 41 must be such that the cable core, which is to be machined, can pass through the filling die with a certain gap. The filler is fed in an excess amount and it flows back to the axial center1 in the container 1.

     Croypro1) is usually placed in front of the grip area and the winding head (m {e shown) for the film wrapping - the filled core of the cable. If space permits, the device B (} can be introduced into the production line and can be located directly behind the twisting point. The cable that is to be processed is moved through the device} by means of an actuator that is already behind the wrapping head which may be a capstan, a crawler tractor, a receiving drum, etc.
    Container 1 is filled with filler 17 to level L, which is maintained by level control 21. By bringing the heating element 16 into operation, the filler 17 is heated to a temperature above the dew point. The desired temperature is regulated and maintained by means of a thermostat 18. The pressure regulator 9 maintains the predetermined pressure required for the cable core to be processed. The core of the cable is squeezed through the device, where it is 1 Roto 1T through the filling head 2 and the filling die 1 and goes to the wrapping head located behind the device. When the desired temperature is reached, the pumps 4 and 14 are turned on. The core of the cable is pulled through the device and in this way is filled with filler 17 during continuous processing and passage through the filling head 2 and a layer of filler is applied to it as it passes through the filling die. The amount of filler is determined by adjusting the pressure. For this purpose, the predetermined pressure, on which the pressure regulator 9 is mounted, is maintained by adjusting the speed of the electric motor 5, which drives the pump 4 through the feedback loop 43. Cutoff. valve 8 serves as a serving capapan and with its help shut off suction pipe 6 during filter cleaning 7.
