    A device for rendering cables such as electric cables, telecommunication cables, optical cables, longitudinally watertight by the block-wise application of a sealing compound into the cable core by means of an intermittently displaceable nozzle which is periodically displaced by a driving element, the speed of the driving element being synchronized with the linear speed of the cable core.

    The invention relates to kabeh (technics, namely, devices for sealing cables.
    The purpose of the invention is to improve the quality of sealing by increasing the reliability of synchronization of the speed of movement of the core of the cable and the injection head.
    Fig, 1 shows the device, a general view; in fig. 2 - the same, top view; on league. 3 - nozzle, longitudinal section; FIG. A is a schematic diagram of the device; FIG. 5 throttle valve, longitudinal section; in fig. 6 - wheel, side view; Figs. 7 and 8 show a throttle valve, a cross section (at the start of the piston movement and at the termination of the air supply, respectively).
    The device (Figs. 1 and 2) contains an injection head 1 with a nozzle 2. The injection head is mounted on a carriage 3, which moves on rollers 4 along guides 5 of frame 6, parallel to the direction of movement of core C of the cable to be sealed. By means of a cable 7, which passes through the pulleys 8, the carriage is connected to the piston 9 of the pneumatic assembly 10 mounted on the frame. A valve 12 is installed on supply line II to regulate the supply of the sealing compound.
    The nozzle (FIG. 3) consists of two parts 13 and 14 and includes an annular pressure chamber 15 j connected to supply line 11 and communicates through the annular gap 16 with a cylindrical chamber 17 through which the cable core C passes.
    The schematic diagram of the device comprises a container, 18, which contains a sealing compound under pressure, connected through a supply line to the nozzle 2 and through valve 19 to a line 20 for supplying pressure, for example, air or nitrogen.
    A compressed air source 21 is connected via an air line 22 to a solenoid valve 23. Through the air line 24, the compressed air is also supplied to an electromagnetic control valve 25 with an air line 26, which serves to control the pneumatic node 10. Electric wires 27 and 28
    connect solenoid valves 23 and 25,
    The throttle valve 29 (Figs. 5-8) includes a housing 30 pivotally mounted on the carriage 3 by means of a lever 31. A valve 32 is installed in the housing 30, which is rotatable. The wheel 33, in contact with the cable core C, is rotated by a freewheel 34, mounted on the cantilever extension of the rotating valve 32. The channels 30 and 36 are located for supplying compressed air to the housing 30 and the rotating valve 32, with the housing connected on one side with a source of compressed air 21, and on the other hand with a pneumatic unit 10. The housing 30 and the rotary valve 32 also contain channels 37 and 38 for the discharge of compressed air.
    The device works as follows.
    In order to make the cable waterproof in the longitudinal direction, the sealing compound is injected under pressure into and around the cable core (preferably at equal distances in the longitudinal direction) during its movement. Using a length measuring device that contacts the heart of the cable and an electric pulse generator (not shown) connected to the wires 27 and 28, the valve 12 opens for a specified period of time (by supplying air to the air line opened by the electromagnetic valve 23 electric impulse generator), at the same time, pneumatic unit 10 is actuated pneumatically by means of an electromagnetic valve 25, which is actuated by said electric generator three pulses, so that the injection head 1 is displaced by the piston 9 together with the nozzle 2 and the wheel 33 with a predetermined initial velocity. This initial velocity is chosen above the linear velocity of the core C cable. Due to the resulting difference in speed by means of the wheel 33, the relative rotation of the valve 32 and the housing 30 occurs. As a result, the air supply to the pneumatically unit W is reduced by the throttle valve 29 until then.
    while the speeds of the core C of the cable and the piston 9 do not match, so that the speed of the dead bass 2 is quickly synchronized with the linear speed of the core C of the cable.
    During the synchronous movement of the nozzle 2, the sealing compound S under a certain pressure in the tank 18 is supplied to the nozzle 2 through the supply line 11 with the valve 12. By the nozzle 2 the sealing material is evenly distributed around the cable core and penetrates into its center cork.
    After the cable core is sufficiently filled with the sealing compound, the control of the solenoid valves 23 and 25 is stopped and the valve 12 returns to its original position, closing the supply line 1 1, the piston 9 of the pneumatic assembly 10 also returns to its original position.
    When the speed of movement of the cable core is changed. Immediately the control of the throttling valve 29 is affected, so that the speed of the piston 9 is again consistent with the speed of movement of the cable core. Due to the presence of channels 3 and 38 in the throttle valve, overshooting of the piston 9 is prevented if the difference between the set initial speed of the piston and the speed of movement of the cable core is very large. Channels 37 and 38 allow air to be very quickly withdrawn from the pneumatic assembly, so that the velocity difference is quickly eliminated. Between the two injections (during the return stroke of the piston 9 and the nozzle 2), the wheel 33 rotates freely due to the free-wheeling mechanism 34, without affecting the throttle valve 29. The direction of free-running of the wheel 33 is shown by the arrow F (Fig. 6). Direction of travel ser 697534
