    This invention relates to devices for color marking of a light guide.
    A device associated with a speed-controlled drive is known, a first output device for winding the light guide with the feed coil, and a receiving coil onto which the light guide is wound after passing through the paint device and after drying the applied paint, positioned after the painting device.
    Communication cables with optical fibers, which may be referred to as optical fiber cables or optical fibers, are cables containing any number of optical fibers made of glass or plastic. Fiber optic cables are used in communication technology instead of ordinary metal wires. They are placed in the core of the superconducting cable, which is surrounded by an outer protective sheath.
    Compared to metallic conductors, the fibers are quite flexible up to certain radii.
    and have a small diameter, with the result that the cable cross-section can be kept small. However, the optical fibers are relatively fragile and sensitive to high tensile and compressive loads; therefore, special care should be taken in the manufacture of optical cables. This is also true for the case of dyeing light guides with different paints and when applying other markings necessary for the accurate identification of individual light guides in the cable for mounting and bonding purposes.
    In the known device, the light guide for continuous coloring of its surface is conducted through a coloring device. The input and output openings of the dyeing device are provided with nipples adjacent to the optical fiber, which exclude the possibility of the paint present in the dyeing device coming out. These nipples are fixed points that can cause damage.

    with
    If the fiber is introduced into the dye yci solution without sufficient accuracy and with oscillations. This is true, in particular, for the case when the fiber is pulled at a high recoil rate through the dyeing device and the subsequent processing sections. In particular, the direction of the light guide, which is accompanied by oscillations, may also cause incomplete staining of the light guide.
    The aim of the invention is to achieve an oscillation-free and uniform fiber during the marking process.
    In front of the dyeing device, there is a second output device associated with a variable speed drive, the speed of which is controlled using a compensator adjacent to the light guide after this device, and that both drives of both coilers are connected to the controller to achieve the same specified number turns.
    With this device, the light guide travels between the second sending device and the first giving device completely evenly at a constant, controlled speed, since both sending devices are driven with the same specified number of revolutions. In addition, the effects on the fiber due to the technological process are compensated for the shortest time by using a compensator, by means of which the speed of the second source device is adjusted. In this way, in general, a completely linear, i.e. Oscillation-free conduction of the light guide through the dyeing device and the following processing sections. For this reason, the possibility of damage to the fiber is eliminated and high quality paint application is ensured.
    The force of the abutment of the compensator to the optical fiber can be adjusted with the help of a load moved by hand. Differently designed light guides and different recoil rates can be taken into account with respect to controlling the rotational speed of the second delivery device.
    FIG. 1 shows a diagram of the proposed device; figure 2 is a detail of the device. From coil 1, light guide 2 is wound in the direction of arrow 3. The type of light guide does not matter. For the winding-up, two delivery devices 4 and 5 are used, which are made, for example, in the form of a disk or roller and are driven by drives 6 or 7 with an adjustable speed (electric motors). The distributing devices 4 and 5 can also be made in the form of a caterpillar or ribbon. They pull light guide 2 coming from feed coil 1 through all machining sections. The treated light guide 2 is finally wound onto a receiving coil 8,
    the speed of which can be adjusted, for example, by means of the compensator 9.
    The light guide 2 is continuously painted in the dyeing device 10, for example, throughout
    its surface. The paint device 10 may further comprise a vibrating device with which a ring-shaped marking is applied to the light guide. After dyeing device
    10, the light guide 2 passes at least one drying section 11 before it gets to the first delivery device 4. The light guide 2 can be pressed, for example, using a roller 12, to the first delivery device.
    device 4, if the latter is formed by a disk or roller or gear.
    In order to provide a straight-line and free from oscillations input of the light guide 2 to the coloring device 8, the second sending device 5, driven with an adjustable speed, is located before the latter. In figure 1, the second sending device 5 is made in the form of a disk to which the light guide 2 presses For example, using the clip-13. The second delivery device 5 is driven by a speed-controlled drive 7, for which the controller 14 sets the same predetermined number of turns,
    as the electric motor 6. The light guide 2 moves, in this way, in both giving devices 4 and 5 with the same speed.
    Distributing devices 4 and 5 represent for fiber 2 a kind of fixed point between which it is clamped. Due to this, a linear and free from oscillations input of the light guide 2 into the dyeing device 10 is provided. Relative to the dyeing device 10 and the following processing sections, for example the drying section 11, the counteractions are controlled for the second distributor 5 - that is adjacent to the light guide 2 and directly causes a change in the number of revolutions or the speed of operation of the second sending device 5, if changes occur during the passage of the light guide 2.
    The compensator 15 can be adjusted in relation to the force of its contact with the optical fiber 2. This is necessary to allow the adjustment of the rotational speed of the second output device 5 with various optical fiber versions 2 and with different feed rates.
    The adjustment of the force of the abutment of the compensator 15 to the light guide 2 can be carried out by means of springs. In the preferred form of execution, a load 16 is located on the compensator 15, which can be displaced by hand in the direction indicated by the arrow 17. Depending on the position of the load for the free end of the compensator 15, in this case there are various forces of abutment.
