Definitions

  • ABSTRACT A longitudinally advancing conductor cable freshly extruded with plastic insulation is marked by a stream of a fluid material of a predetermined color as follows: The stream is first ejected from a high-pressure nozzle, sinusoidally deflected by electrical deflection means, and then the deflection is amplified to be substantially larger than the cross-sectional dimension of the cable by an electrical amplifying means before the stream is applied transversely to the cable. Where a complete band mark needs to be made around the cable, a second stream may be applied to the cable opposite to the side being marked by the first stream, by deflecting and amplifying the second stream in the same manner as the first stream.
  • the band marks made by each stream may be matched more precisely by bending the second stream toward the advancing direction of the cable and by controlling the degree of bending to match the first stream as the two streams hit the cable.
  • a plurality of streams of different or the same color materials may be applied to the cable simultaneously at given intervals after being deflected and amplified in the same manner as the first stream.
  • the present application relates to a method of and an apparatus for marking a cable and more particularly, for band marking plastic-insulated conductor wires with streams of various different color materials in a fluidic state.
  • the oscillating frequency of the nozzles and, consequently, the maximum production speed are largely dictated by the inertia of the mechanical oscillating syster in the apparatus that provides up and down movement to the nozzles.
  • the maximum oscillating frequency that such apparatus can reach is about 500 Hertz.
  • the production speed is limited to a maximum of about 300 meters per minute (m./min.).
  • the operating frequency is usually maintained below 300 Hertz, which, with the above-mentioned color band spacing, results in a production speed of approximately 180 m./min. Even with such a greatly reduced production speed, the mechanical oscillating system of the apparatus has a limited service life.
  • the aforementioned objects are achieved by advancing the cable longitudinally in a given direction, forming a stream of a fluid material of a given color, electrically deflecting the stream sinusoidally in a transverse direction, electrically amplifying the amplitude of the deflection of the stream to a magnitude greater than the cross section of the cable, and then applying the stream transverse to the advancing cable.
  • the method may further include forming a second stream of a fluid material of the given color, deflecting and amplifying the second stream in the same manner as the first stream and then applying the stream opposite the side of the cable marked by the first stream for completing the mark around the cable.
  • one of the streams may be electrically bent after its amplification in the direction of the advancement of the cable and the extent of bending adjusted to match one stream against the other stream.
  • a plurality of streams of different colors may be formed, deflected and amplified and applied to an advancing cable for forming a plurality of bands around the cable simultaneously.
  • a novel apparatus for performing the method comprises a means for ejecting the fluid material of a predetermined color in the form of a stream at a relatively high pressure, an electrical deflection means for deflecting the stream sinusoidally transverse to a longitudinal advancing cable, and an electrical amplifying means for amplifying the extent of the sinusoidal deflection of the stream to be substantially greater than the cross-sectional dimension of the cable prior to the application of the stream to the advancing cable.
  • the apparatus may include a second set of the aforementioned various means for applying another stream opposite the first stream to effect a complete band mark.
  • the apparatus may further include a DC displacement electrode for applying a DC field nonsymmetric to the axis of the path of one of the streams to bend it laterally in the direction of the advancement of the cable and means for varying the DC field to adjust the extent of bending of the stream to match it with the other stream in forming the complete band mark.
  • the apparatus may also include a plurality of pairs of ejecting, deflecting and amplifying means, and displacement electrodes arranged to mark a plurality of bands simultaneously on the advancing cable.
  • FIG. I shows a side view in partial cross section of the deflection system
  • FIG. 2 schematically shows a novel apparatus for practicing the inventive method
  • FIGS. 3a, 3b and 3c show side, front and top views respectively of the deflection system with a displacement electrode
  • FIG. 4 shows a top view of a deflection system for simultaneously applying a plurality of marks to the insulated conductor.
  • a color material in a fluidic state is forced out of a fixed nozzle 1, at a pressure from 1.5 to I .8 times that of atmospheric pressure, to form a thin horizontal stream of color material 3.
  • the noule l is electrically connected to a ground potential and has an orifice of about 0.5 mm.
  • the stream is then applied through a bipolar electrodynamic deflection system 2 consisting of two round wire electrodes of about 2 mm. in diameter and positioned about 5 mm. from the nozzle.
  • the two electrodes are spaced about 2.5 mm. from each other, and are preferably insulated.
  • Electrode spacing and insulation of the electrodes allow the material to drip off from the electrode and thus avoid the undesirable brush discharge of the color material found in the prior art.
  • positive or negative halves of sinusoidal voltage pulses of 3 to 5 kv. peak voltage are alternately applied to the deflecting electrodes to deflect the color stream 3 sinusoidally.
  • the amplitude of the oscillations of the color stream is mainly dependent on the amplitude of the voltage pulses, the pulse frequency, the amount of color material being ejected and the relative dielectric constant of the color material 3.
  • the mark formed on the cable is clean and sharply defined when the amplitude of the oscillation is deflected to the extent of at least four times the diameter of the insulated conductor 4 at the point that the stream is applied to the conductor.
  • the required amplification was obtained by a cylindrical amplifying electrode 5 arranged about 10 mm. from the electrodes of the electrodynamic deflection system 2 and by applying a variable DC potential to the amplifying electrode.
  • the applicants have found that by varying the DC potential from 2 to 5 kv. it was possible to realize up to a five fold increase in the amplitude of oscillation.
  • the insulated conductor 4 is so positioned that it advances horizontally along its longitudinal axis at a distance of about to 40 mm. from the amplifying electrode 5.
  • FIG. 2 also shows an electrical circuit for generating the high voltage pulses.
  • the circuit includes an audio-oscillator 6, a power amplifier 7 and a rectifier 2, in tandem.
  • the audiooscillator 6 may be of the type which is controllable with respect to its frequency and voltage, or of a tachogenerator type which is synchronizable with the advancing speed of the wire.
  • the output of the oscillator is amplified by a power amplifier 7 to a required voltage and then applied to the rectifing means 2 through a transformer 8.
  • the voltage from the two symmetrical secondaries of the transformer is applied respectively to two diodes 9 and 10 of the rectifing means and then applied to the two deflecting electrodes 2 through short, lowcapacitance and low-leakage lines.
  • a reservoir 11 contains a suitable color material and supplies the material under a high pressure by compressed air from a stock bottle 12 fed through a valve 13.
  • two deflection apparatus may be positioned on opposite sides of the conductor.
  • the two deflection apparatus may be staggered from each other along the insulated conductor by one or several band spacings. In some applications a fine adjustment may be necessary to match the two half hands.
  • a displacement electrode 14 such as that shown in a side view in FIG. 3a, in a front view in FIG. 3b, and in a top view in FIG. 30.
  • the electrode is connected to a controllable DC high-voltage potential source and applies a DC field which is nonsymmetric to the axis of the path of the color stream material.
  • the electrode may be of any suitable shape.
  • the color stream may be in a boxlike form, as shown, or in an oval, platelike or filamentary shape.
  • this displacement electrode When the color stream is directed past this displacement electrode, it is deflected toward the nearest plate and preferably bent laterally in the direction of the advancing cable.
  • the deflection angle, and consequently matching of the stream to the other stream, can be readily controlled by increasing or decreasing the DC potential applied to the plate to control the deflection angle.
  • the marking on the opposite side of the cable 4 is provided by a second color stream 3 from a second deflection apparatus 5' of the type illustrated in FIG. 1.
  • FIG. 4 shows an apparatus which simultaneously applies triple bands on the advancing conductor 4.
  • Three streams of different or the same color material emerge from three nozzles.
  • the three color streams are then sinusoidally deflected by deflection electrodes 2 common to all three streams.
  • the deflection amplitude of the three streams are amplified by three individual amplifying electrodes 5 of the type discussed above.
  • the novel method and apparatus provide several important advantages over the prior art.
  • the present invention eliminates the need for mechanically oscillating components and thus provides an increased life expectancy of the apparatus and permits a simplified structure.
  • the electrical control means in the apparatus makes it possible to have more precise control in matching the bands and to substantially increase the marking speed and thus the production of the cable.
  • the applicants have found that it was possible to increase the frequency of oscillation to L400 Hertz, using the above mentioned band spacing of 5 mm., with excellent results. This yielded a production speed of about 850 m./min. which compares very favorably with the prior art method that yielded up to 180 m./min.
  • An apparatus for marking a cable with a fluid material of a predetermined color comprising:
  • a first means ejecting said fluid toward said cable in the form of a stream at a relatively high pressure
  • a first electrical deflection means for sinusoidally deflecting said stream transverse to the longitudinally advancing cable
  • a first electrical amplifying means for amplifying the magnitude of the sinusoidal deflection of said stream to an extent substantially greater than the cross-sectional dimension of said cable and applying the amplified deflected stream to the advancing cable.
  • said first deflection means includes a first and a second electrode disposed adjacent said ejecting means and on opposite sides of said stream, and an electrical power source applying a sinusoidally varying electrical potential to said first and second electrodes.
  • said first electrical amplifying means includes an electrode having a hollow internal tapered profile, the axis of said tapered profile being aligned with the cable, the electrode being positioned so that said stream enters at the narrow end of the tapered profile and exits at the broader end of the profile; and a variable DC potential source controlling the magnitude of the amplification of said electrical amplifying means.
  • the apparatus of claim 2 further includes a second stream ejecting means, a second electrical deflection means, and a second electrical amplifying means arranged for applying a second stream of said material of the predetermined color opposite the side of the cable to said first ejecting, deflection and amplifying means for completing the mark around the cable.
