  • a transfer module takes over the finished trailing conductor ends and transfers them to a holding module.
  • the conductor pair located between the holding module and the twisting head is twisted with controlled tensile force and then passes into a tray.
  • the leading conductor ends of a pair of conductors are processed and equipped, an extended pair of conductors is processed, equipped and transferred, and a conductor pair is twisted.
  • the object is achieved by a method for twisting a plurality, ie at least two, preferably three or four, of individual lines, in which in a step (a) the individual lines are introduced at a first position into a fixing unit, in a step (b ) the individual lines are fastened to a second position spaced apart from the first position in the line longitudinal direction in respective support elements of a de-twisting unit, in a step (c) the individual lines are inserted longitudinally displaceably into a twisting unit between the first position and the second position, in a step ( d) the individual lines between the fixing unit and the untwisting unit are tensioned, in a step (e) the individual lines are twisted by means of a rotary movement of the twisting unit, wherein the twisting unit is moved from the fixing unit to the untwisting unit, and (f) the untwisting unit with the individual wires one to the D rehitchieri the twisting unit performs corresponding rotational movement.

  • This ensures that the support elements of the Entdrillinheit are indeed rotated in space around a common axis of rotation, the angular orientation or rotational position of the individual support elements in space but remains the same.
