  • the rotation of the individual rotary units 41, 42 ensures that the individual lines do not twist in themselves, ie about their respective line axis v1, v2.
  • the guide device 35 moves at a controlled speed in the direction of the untwisting unit 40, the controlled speed resulting from the rotational speed of the twisting unit 30 and the desired lay length a2.
  • the twisting unit 30 is also minimally towards the untwisting unit 40 in order to compensate for the shortening of the twisted line bundle 10 caused by the twisting. This movement can take place, for example, under tension control.
  • the thickening reduces 361 on the guide mandrel 360 the vertical oscillation of the lines 11, 12 and thus improves the quality of the twisting process.
  • an intermediate position is shown, which is assumed after the start of the twisting process and before the completion of the twisting process.
  • 20 and 21 each show a plan view of the individual rotating units 41, 42 shortly before the twisting process is completed.
  • the guide pin 360 is still in contact with the individual lines 11, 12.
  • the guide device 35 moves the guide pin 360 further so that it is in contact with the individual lines 11, 12 loses, as in 21 shown.
  • the distance 45 between the individual rotary units 41, 42 was further reduced from one another.
  • the actual twisting process is complete.
  • a final twisting process follows, in which the twisting unit 30 is again rotated in the twisting direction, with the first crossing point P1 being moved even closer to the conductor ends.
  • twisting process and the subsequent final twisting process are then completed, and the finished twisted cable is released from the twisting unit 30 and the individual turning units 41, 42 and placed, for example, in a cable trough 160 (see 4 ) dropped.
  • the twisting unit 30 that is no longer rotating can be moved further in the direction of the untwisting unit 40 in order to relax the twisted line bundle.
  • the brake 53 by actuating the brake 53, the angular position of the individual rotating units 41, 42 can be blocked.
  • FIG. 22 shows the elements of the device 100 in a position in which the guide device 35 its linear Movement has continued until the guide mandrel 360 has approximately reached the ends of the line.
  • An unlocking cylinder (not shown) now actuates the point 357, whereby the released spring force causes the guide mandrel 360 to move into the in 23 shown position outside of the extension axis A pivots.
  • the guide device 35 can now be moved to the starting position without the guide mandrel 360 having a disruptive effect on this movement.
