Definitions
- the disclosure relates to a method and a device for twisting individual lines, in particular for twisting individual lines in pairs to form a bundle of lines.
- cable bundle twisting In various industrial fields of application, cable bundles are required which are obtained from individual cables by twisting (hereinafter: cable bundle twisting).
- the individual lines each have a stranded wire, which in turn is formed from twisted wires (hereinafter referred to as: stranded twisting).
- An insulation surrounds the respective strand of the individual line.
- the individual lines are cut to a certain length before twisting the bundle of lines, ie cut to length, and possibly also ready-made, ie see ver with a contact part or the like.
- EP 1 032 095 A2 discloses a twisting device for the simultaneous processing of three pairs of conductors. A pair of conductors, ie a pair of individual lines, is clamped between a holding unit and a twisting head.
- the twist head is rotated about a twist axis, whereby the twisting process is carried out.
- the resulting shortening of the line pair is compensated for by shifting the twisting head parallel to the twisting axis.
- the twisting device disclosed in EP 1 032 095 A2 is used both for assembling and for twisting the lines (hereinafter referred to as automatic production).
- a twisting device is only used for twisting, but not for assembling the lines (hereinafter referred to as semi-automatic production).
- a device according to the modification he compensates for the twisting-related shortening of the line pair, for example, by shifting the Hal teech parallel to the twisting axis.
- WO 2013/068990 A1 discloses a twisting device similar to the twisting device disclosed in EP 1032 095 A2, two twisting heads being provided which rotate in opposite directions.
- WO 98/06155 A1 discloses a twisting device like the twisting device disclosed in EP 1032 095 A2, where instead of the holding unit per line end an untwisting unit is provided which rotate in the same direction of rotation as the twisting head during the twisting process.
- the predetermined properties that a wire bundle obtained by twisting a wire bundle should have include, among others. a desired lay length, or twisted lay length, and a desired lay number, or twisted lay number.
- the lay length is generally understood to mean the distance or the mean distance between two adjacent, similar crossings of the individual lines from one another when projected onto the plane. The number of strokes then results from the sum of these crossovers.
- the cable bundle obtained by twisting the cable bundle always has a certain elasticity about the twisting axis.
- the line bundle (here: line pair) tends to reverse itself again after the twisting process has been completed To untwist the twisted state, i.e. to untwist at least partially.
- the number of strokes and / or the length of the lay can vary in an impermissible manner or deviate from the specified values.
- WO 98/06155 A1 attempts are made to avoid excessively high torsion forces by the untwisting units performing torsion compensation during the twisting process. Since the cable ends in the untwisting units are no longer clamped in a rotationally fixed manner in relation to the twisting head, a guide unit in the form of a drill ship is provided for specifying the lay length. The guide unit separates the two cables with a pin and moves from the twisting head towards the untwisting units during the twisting process .
- a method for twisting individual lines about a twisting axis comprising holding the first line ends separately and holding the second line ends and then jointly rotating the second line ends about the twisting axis counter to the strand twisting direction to generate a twisted bundle of cables with a predetermined or predeterminable twist number and / or with a predefined or specified twist length.
- a device which is configured to carry out the method described herein.
- the device has individual rotating units and a twisting unit.
- the individual rotating units are configured to hold one of the first line ends separately.
- the twisting unit is configured to hold the second line ends.
- the individual rotating units and the twisting unit are arranged in such a way that they hold the individual lines essentially parallel to the twisting axis.

- FIG. 4 shows a twisting device 400 analogous to FIGS. 2 and 3, which can be used to carry out a method disclosed herein according to an embodiment.
- the twisting device 400 differs from the twisting device 100 from FIG. 1, among other things, in that a single turning unit 41 is provided for clamping the first end 15 of the individual line 11, and that a single turning unit is provided for clamping the second end 16 of the individual line 12 unit 42 is provided.
- the single rotating unit 41 is arranged in such a way that it holds the first end 15 of the clamped single line 11 along its line axis vl at the first end 15.
- the individual rotating unit 42 is arranged in such a way that it holds the first end 16 of the clamped individual line 12 along its line axis v2 at the first end 16.
- both individual rotating units 41, 42 are also arranged in such a way that they hold the individual lines 11, 12 at the respective first ends 15, 16 essentially parallel to the twisting axis V.
- the twisting device 400 also comprises a guide device 35 for at least regionally separating the individual lines 11, 12.
- the guide device 35 is displaceable in a direction x essentially parallel to the twisting axis V.
- the twisting unit 30 can also be rotated about the twisting axis V in the twisting device 400 according to FIG. H. rotatably drivable around the twist axis.
- the individual rotating unit 41 can optionally be rotated back and forth about the line axis vl. This is indicated by the double arrow Q1 in FIG. 4.
- the individual rotating unit 42 can optionally be rotated back and forth about the line axis v2. This is indicated by the double arrow Q2 in FIG. 4.

- each of the first line ends 15, 16 is rotated separately about its respective line axis vl, v2 during this joint rotation, specifically in the same direction of rotation as this joint rotation. For example, he does this by driving the associated Einzelrehein device 41, 42 in the appropriate direction of rotation Ql or Q2. As a result, the respective individual line 11, 12 is untorted.
- Untorting includes, for example, a reduction or elimination of a torsional force or a torsional moment that would be generated by rotating together in each individual line 11, 12.
- the untwisting, or untwisting does not necessarily have to be complete to achieve the advantages described herein.
- the (total) angle of rotation of the twisting unit 30 can be smaller than the (total) angle of rotation of the individual rotating units 41, 42.
- Counter-blow denotes the counter-rotation between the (rotary) line twisting direction and the (rotary) strand twisting direction.
- Fig. 5 shows schematically the cable bundle 10 from two examples of individual lines 11, 12 and their respective strands in two variants:
- variant A left in Fig. 5
- the strand twisting direction when looking at the end of the wire runs clockwise (strand twisting direction S).
- the twisted ones Wires 11a, 12a which form the braid in variant A, therefore run from top left to bottom right in the projection plane shown.
- the individual lines 11, 12, which form the twisted bundle of lines 10 in variant A, therefore run in the projection plane shown from the bottom left to the top right (line twisting direction Z).
- variant B on the right in FIG. 5)
- the strand twisting direction runs counterclockwise (strand twisting direction Z) when looking at the conductor end.
- the twisted wires 11a, 12a which form the stranded wire in variant A, therefore run from the bottom left to the top right in the projection plane shown.
- Fig. 6 shows a diagram in which qualitatively the United twist lay length a (the cable lay length) is plotted against the strand lay length b, namely with a Ver twist in Lang lay according to the prior art.
- Fig. 7 again shows a diagram in which qualitatively the Ver twistschlag length a (the cable lay length) is plotted against the strand lay length b, namely with a Ver twist in the opposite direction as in the procedure described here Ren.

- the area in which the bundle of lines can no longer be produced is indicated in each case with the reference numeral 70. It turns out that proceeding in the opposite direction according to the method described here results in a decisive process improvement.
- the method further comprises - before rotating together - a separate rotation of each of the first line ends 15, 16 about the line axis v1, v2 of the respective individual line for pre-twisting.
- Pre-twisting comprises a targeted application of a torsion to the respective individual line before the twisting process.
- the pre-torsion takes place in such a way that torsion-related damage to the respective individual line is avoided.
- the pre-twisting has an effect comparable to the over-twisting described above with reference to the prior art with subsequent back-twisting. It has been shown, however, that the strands are less stressed.
- the individual lines 11, 12 in the twisted line bundle 10 lie closer to one another and the size of the eyes is reduced without the pretensioning having to be increased.
- the twisted line bundle 10 also remains more dimensionally stable. There is also the tendency to automatically untwist the untwisted line ends 15, 16; 17, 18 reduced.
- the separate turning for pre-twisting is carried out in the strand twisting direction S, Z in each case.
- the geometry of the helix of the twisted bundle of cables 10 in the respective individual cables can be compensated, whereby the torsion in the twisted bundle of cables 10 is reduced or even completely eliminated.
- the separate twisting for pre-twisting is carried out against the strand twisting direction S, Z in each case.
- the formation of large eyes can be further reduced.
- the tendency to automatically untwist the untwisted line ends 15, 16; 17, 18 further reduced.
- the separate turning for twisting each of the first line ends 15, 16 is carried out by an angle of rotation which is at most 10% of the total angle of rotation of the second line ends 17, 18 necessary to achieve the number of twisting strokes. It has been shown that such a pre-twisting of a maximum of 10% of the number of strokes can be sufficient to achieve the effects and advantages described herein.
- the method further comprises repeatedly determining a variable that is related to a torsional moment or a torsional stress of at least one of the individual lines.
- the separate rotation of the first line ends around the line axis of the respective individual line is carried out until the determined size falls below a predetermined or determinable threshold value.
- the method further comprises cutting the individual lines to length.
- the method further comprises attaching one or more contact parts 13a, 13b, 14a, 14b to at least one of the first line end 15, 16 and the second line end 17, 18.

- the twisting unit 30 is movably arranged parallel to the twisting axis V.
- all of the individual rotating units 41, 42 are movably arranged parallel to the twisting axis V be.
- the device 400 is configured, for example, in such a way that it moves the first and second line ends 11, 12 towards one another by means of the movably arranged twisting unit 30 and / or individual rotating units 41, 42 to compensate for the shortening of the bundle of cables caused by twisting.
- the twisting unit 30 is arranged so as to be movable parallel to the twisting axis V be.
- all of the individual rotating units 41, 42 are movably arranged parallel to the twisting axis V be.
- the device 400 is configured in such a way that it applies a tensile force essentially parallel to the twist axis V for stretching the individual lines 11, 12 and / or the line bundle 10. The stretching can take place before the twisting and / or during the twisting. In this way, a further improved uniformity of the twisted bundle of wires 10, in particular the lay length a, can be achieved.
- the device 400 comprises the guide device 35 for at least regionally separating the individual lines 11, 12.
- the guide device 35 is displaceable in a direction x essentially parallel to the twist axis V.
- the device 400 is configured in such a way that the guide device 35 is essentially synchronous with a rotation-related variable of the twisting unit 30 in the direction x of the first line ends 15, 16 is moved. This allows a further improved
