Definitions

  • the present invention relates to a method of twisting at least one insulated conductor of an electric cable before its stranding with similar conductors. It also extends to a device for implementing this method.
  • the metallic conductor of copper or aluminum must be perfectly centered in an insulator made of plastic or elastomer. (in particular polyethylene, polyvinyl chloride, polytetrafluoroethylene). In case of drift of this centering, delicate to maintain during the insulation of the wire, this drift is compensated for by a twist of the insulated conductor. This statistically amounts to distributing the shift along the conductor.
  • the present invention aims to provide a twist of the conductor by a simpler process, not subjecting it to significant efforts and not requiring monitoring and careful maintenance of the bodies ensuring the torsion.
  • the method according to the invention is characterized in that the conductor is advanced between and in contact with two rollers of parallel axes in the same vertical plane and substantially perpendicular to the direction of advance of the conductor, and movable in rotation around their axes, at least one of the rollers being in alternative translations along its axis, then on an acceptor member blocking the conductor in its state in torsion.
  • the invention also extends to a device for implementing the method defined above, characterized in that it comprises at least one member for supplying an isolated conductor, one member for advancing the driver, two torsion rollers, at a significant distance from the supply member, with parallel axes in the same vertical plane, and substantially perpendicular to the direction of advance of the conductor, means for driving at least one first roller in alternative translations along its axis, the spacings of the axes and the diameters of the rollers being such that the conductor passes between them and is in contact with both, and an acceptor blocking the conductor in its torsional state in the vicinity of the rollers.
  • Rollers of this kind are known from document EP-A-0 007 472 (date of publication of the request 06.02.80; priority 28.07.78), but they are arranged there individually not in pairs, and with an oblique axis by relative to the axis of advance of the conductors to be stranded.
  • Figure 1 shows in perspective the two conductor torsion rollers, their drive mechanism and the conductor blocking pulleys in the torsional state.
  • Figure 2 shows on an enlarged scale a cross section of the conductor at the place where it is in contact with the rollers.
  • the insulated conductor 1 arriving from a remote supply coil, passes between the two rollers 2 and 3 with a surface coated with an elastomer, for example of neoprene rubber.
  • an elastomer for example of neoprene rubber.
  • the coefficient of friction of the coating of the rollers must be chosen according to the nature of the insulation of the conductor, so as to ensure a rolling as free as possible from sliding of the insulated conductor on the rollers. If, for example, the insulator of the conductor, instead of being made of compact synthetic polymer, was made of cellular polymer, the elastomeric coating of the rollers should be notably more flexible.
  • the rollers 2 and 3 are carried by rods in the same vertical plane 4, 5, on which they are movable in rotation.
  • the rods slide in fixed ball bushings 6, 7, 8, 9. They are connected by a chain 10 passing over the teeth of wheels with a horizontal axis such as 11.
  • the displacement of the rods 4, 5 is controlled by a jack pneumatic (or hydraulic) cushioning shown schematically in 12.
  • the torsional conductor is locked in the torsional state by passing through the deep V-shaped grooves of pulleys 13, 14 of horizontal axis, arranged in the vertical plane passing through the advance axis of driver.
  • the arrangement of the pulleys 13 and 14 is such that after passing through the groove of the pulley 13 the conductor is moved upward to pass through the groove of the pulley 14, and that at the exit of the latter its axis of advances either at a height greater than that of its initial axis of advance.
  • the pulleys 13, 14 are placed at a distance from the rollers which can be adjusted as a function of the length of the torsion step applied to the conductor, so that the rotation of the conductor is optimal.
  • the diameters of the rollers are chosen according to the linear speed of the conductor and the adhesion of the insulator thereof to their coating, so that they do not rotate too quickly. Their length is chosen as a function of the number of twists to be printed on the conductor in each direction, and of the resulting space requirement for the device.
  • rollers have been shown carried by rods movable in translation in fixed ball bushings. One could naturally also make them support by fixed rods on which they would slide in translation thanks to movable ball bushings, which would then be connected to the endless chain of transmission of movement from one roller to another.
  • rollers could not be connected by a chain, but be independent of each other and both controlled by a jack.
  • the conductor could not be locked in torsion in the grooves of two pulleys, but directly reach an assembly machine with other conductors in pair, quarte, fifth, strand or cable in system with helical winding pitch alternated.
  • the device described can be used to twist several isolated conductors simultaneously.
  • the invention applies more particularly to the twisting of insulated conductors for telephone cables.
