Definitions

  • SZ stranding reversing stranding (SZ stranding) of at least one stranding element of a cable with a laying device arranged between a stranding disk and a standing disk, which has at least one laying disk which is driven with the same direction of rotation as the stranding disk and a lower speed, whereby the standing disk, stranding disk and the Have at least one laying disk take-through openings for at least one stranding element and wherein the at least one laying disk is driven by a drive motor specially assigned to it, the speeds and directions of rotation of which are independent of one another and also independent of the rotational speed of the drive motor of the stranding disk can be adjusted such that the on the at least a maximum tensile accelerations acting on stranding elements are reduced.
  • the direction of rotation, the oscillation frequency and the deflection of perforated disks driven by individual motors can be set independently of one another.
  • the invention has for its object to design the device of the type mentioned in such a way that the tensile forces exerted on the stranding elements are reduced, so that higher stranding speeds are possible.
  • the solution is achieved in that the individual speed of each laying disc between two reservation points can be varied in a manner dependent on the angle of rotation.
  • stranding elements 3 containing optical waveguides are stranded in a reversing direction of twist around a central element 2 pulled off in the direction of arrow 1 at a constant speed.
  • the stranding element 3 is pulled off the drum 5 via a dancer arrangement 4. It is then passed through through-openings of the stationary stand plate 6, the laying disks 7 to 11 and the stranding disk 12 up to the stranding nipple 13, where it is placed around the central element 2 alternately with right and left twist.
  • the stranding is predetermined by the stranding disk 12 rotating alternately to the right and left.
  • the laying disks 7 to 11 rotate in the same direction as the stranding disk 12, but the level of the rotational speed of the laying disks 7 to 11 decreases steadily towards the standing disk 6.
  • the longitudinal speed of the stranding element 3 also changes periodically between a minimum and a maximum value at the location of the arrow 14. Associated with this are positive and negative accelerations which, due to the effective inertial masses (dead weight of the stranding elements, movable dancer element 15, drum 5), lead to periodically fluctuating tensile forces in the stranding element 3.
  • these tensile forces are proportional to the pull-off speed of the center element 2 and, on the other hand, on the movement sequence of the laying disks 7 to 11, which cause an alternating force to be superimposed.
  • the maximum value of this alternating force can be reduced to approximately half that a separate drive motor 16 to 20 is provided for each of the laying disks 7 to 11.
  • the engine speeds are independent of one another and can also be controlled independently of the rotational speed of the drive motor 21 of the stranding disk.
  • Each of the drive motors 16 to 20 is a disc motor 22 (Fig. 2).
  • An ironless disc rotor has a particularly low GD2, which can be further reduced with permanent magnetic excitation.
  • the motor 22 drives one of the laying disks 16 to 20 via a V-belt 23.
  • Angle of rotation ⁇ and speed of rotation ⁇ are measured by a tachometer generator 24 and entered as actual values of a program circuit 25.
  • FIG. 3 shows how the differential speed ⁇ between two adjacent laying disks (for example 19 and 20) runs as a function of the differential angle of rotation ⁇ between the disks.
  • the value ⁇ 0 arises then when all lead-through openings of the laying disks 7 to 11 are aligned with those of the standing disk 6 and the stranding disk 12.
  • the direction of rotation is reversed at a differential angle of rotation of approximately 180 o .
  • the invention was explained on the basis of the description of an exemplary embodiment in which all the laying disks are continuously driven simultaneously.
  • the invention can, for example, be used equally well for devices known from DE-OS 35 36 488, in which the laying disks are driven discontinuously in such a way that the maximum angle of difference between adjacent laying disks is built up individually and subsequently for the laying disks following the standing disk.
