EP1784841B1 - Device and method for stranding a long winding material - Google Patents

Description

The present invention relates to a device and a method for stranding elongated winding material, in particular of metallic winding material, such as wires, strands, cables and insulated conductors, such as wires, and the like.

An entire system for stranding elongate winding material, which also has a device for stranding of elongated winding material, and a method for stranding elongate winding material using this device is also known from US 6,427,432 B1 known.

The Gesamtverseilungsanlage from US '432, a so-called "lyre-type horizontal pairing machine", in short "PHL", has a horizontally arranged Rotorbügelablaufsystem with rotating rotor bracket, arranged within a spanned by the rotating rotor bracket body and by the rotation of the rotor yoke decoupled drainage system is used as a tangential drain for a first wire.

A second wire is withdrawn from a second drainage system, which is arranged in the withdrawal direction in front of the Rotorbügelablaufsystem, and guided over the rotor yoke of the Rotorbügelablaufsystems.

At the end of the Rotorbügelablaufsystems the device for stranding the first and the second wire, a stranding drum, - a functionally important element for the merger of the two individual wires - arranged.

This stranding drum, a cylindrical body of revolution, has a first passage for guiding the first wire the stranding drum and a second passage for guiding the second wire through the stranding drum.

The first feed connects a first, central input at the input end face of the stranding drum with a first eccentric output at the output end face of the stranding drum. The second feedthrough connects a second, eccentric input on the input end face of the stranding drum with a second, also eccentric output on the output end face of the stranding drum.

After passing through the stranding drum, the first and the second strand are stranded together in a stranding point.

A disadvantage of the "PHL" appears that there - because of the structural design of the "PHL" - the two individual wires to be stranded through the entire length of the stranding drum, which means that the stranding drum are arranged in the whole in the withdrawal direction after the Rotorbügelablaufsystem can. This runs counter to a general requirement for compact designs of complete stranding systems.

Next proves to be in the "PHL" of disadvantage that this can be operated in the described embodiment, in particular the configuration of the stranding drum, only as a stranding for stranding of two wires. An operation of the Rotorbügelablaufsystems as reverse turning device for a single wire appears in the "PHL" only under correspondingly complicated conversion of the "PHL" possible. The "PHL" from the US '432 thus appears as less flexible.

The present invention is therefore an object of the invention to provide a device and a method for stranding of elongated winding material, which allows more compact designs of Gesamtverseilungsanlagen.

This object is achieved by a device and a method for stranding elongate winding material having the features according to the respective independent claim.

The device according to the invention for stranding elongated winding material has a substantially cylindrical rotational body with at least one first passage for guiding a first winding material through the cylindrical rotational body and at least one second passage for guiding a second winding material through the cylindrical rotational body.
The first feedthrough connects a first eccentric or peripheral input on a first end side of the rotary body with a first eccentric output on a second, opposite the first end face of the rotary body.

The second feedthrough connects a second input, arranged on a surface of the rotary body extending between the two end faces, to a second eccentric outlet on the second end face of the rotary body.

In the method for stranding elongated winding material, a first winding material is guided through a first passage of a substantially cylindrical rotational body and a second winding material through a second passage of the substantially cylindrical rotational body.

The first and the second winding material are stranded after passing through the substantially cylindrical body of revolution in a stranding point.

The first feed connects a first eccentric input to a first end face of the rotating body with a first eccentric output a second, opposite the first end face of the rotary body.

The second feedthrough connects a second input, arranged on a surface of the rotation body (cylinder surface) extending between the two end faces, with a second eccentric output on the second end face of the rotation body.

It should be understood here by the terms "eccentric" or "peripheral" or an "eccentric or peripheral input / output" that a radial offset or a radial distance (an input / output) to a rotation axis or Central axis of the substantially cylindrical rotational body is present.

The opposite term "centric" or "central" used here accordingly means that there is no radial offset or no radial distance (an input / output) to the axis of rotation or center axis of the substantially cylindrical rotary body and such centric input / output on the axis of rotation or center axis of the substantially cylindrical body of revolution is located.

Preferred developments and embodiments of the invention will become apparent from the dependent claims.

The embodiments and / or developments described below relate both to the method and to the device.

Thus, for the stranding optionally multiple veins formations can be used, in which one, two or even more further first passages and / or one, two or even more further second passages are respectively provided for guiding further winding material through the cylindrical body of revolution.

In this case-in the case of the at least first second feedthrough and a further second feed-through - the second eccentric output of the further second feedthrough can be arranged opposite the second eccentric output of the at least first second feedthrough.

It can also be provided in a preferred embodiment to arrange the second, eccentric output of the second passage and the first, eccentric output of the first passage on the same end face of the cylindrical body of revolution.

In a further development of this preferred embodiment, the two eccentric outputs can be arranged such that they have the same radial distance from an axis of rotation of the cylindrical rotational body and, in particular, lie opposite 180 °.

In a further preferred embodiment, the first and / or second feedthrough are substantially parallel, in particular at the same radial distance from each other, to the axis of rotation of the substantially cylindrical rotational body.

Particularly advantageous in particular with regard to compact designs of stranding systems proves to be, if the cylindrical body of rotation part of a rotor shaft of a rotor bracket, in particular a Rotorbügelablaufsystems, and / or with a rotor bracket, in particular a Rotorbügelablaufsystems, co-rotated and / or co-rotating connected is. In these cases, the stranding device or the rotational body proves to be integrated into a rotor hanger drainage system and / or as an integral element of a rotor hanger drainage system.

A vein guide can be improved - and thus reduced friction loss - be, if at the second input a guide device to a guided inlet of the second winding material, in particular a deflection roller, is arranged.

In a further preferred embodiment, a third passage for guiding a third winding material is provided by the cylindrical rotational body. This third passage can be designed such that it connects a third centric inlet on the first or second end face of the rotation body to a third exit, arranged on the surface of the rotation body (cylinder surface) extending between the two end faces.

Preferably, however, the third winding material may be guided in an alternative operation through the rotary body instead of the first and the second winding material. Thus, for example, a normal operation, in which the first and the second winding material are guided by the rotary body, a stranding of the first and the second winding material, whereas the alternative operation in which the third winding material - instead of the first and the second winding material - by the rotational body is guided, can be a reverse rotation of the third winding material.

Again, it can be provided that at the third output a guide device to a guided outlet of the third winding material, in particular a deflection roller, is arranged.

Furthermore, it can also be provided here that the first and the third and / or the second and the third and / or the first, the second and the third passage are substantially parallel to one another and / or to a rotation axis of the substantially cylindrical rotation body.

It can also be provided that the substantially cylindrical rotational body made of a metallic material, such as steel or aluminum, and / or a passage through the rotational body is a (longitudinal) bore or a (longitudinal) groove or the like.

The particular flexibility allows use in the context of a stranding or pre-stranding of at least two wound goods as well as in the context of a reverse rotation of a single winding material.

In use for stranding, in particular for Vorverseilung, the first winding material, in particular a first wire, and the second winding material, in particular a second wire, in particular of metallic first and second winding material, such as wires, strands, cables and the like, the first winding material guided through the first implementation. The second winding material is passed through the second implementation. After passing through the cylindrical body of revolution, the first and the second winding material are stranded in a stranding point.

Further, in the stranding, in particular the Vorverseilung, the first and the second winding material are provided that the second winding material is guided in the withdrawal direction before passing through the second implementation of a rotor bracket of a Rotorbügelablaufsystems and / or that the first winding material in the withdrawal direction before implementation by the first implementation is deducted from a used as a tangential drainage system of the Rotorbügelablaufsystems.

In addition, can be provided in the stranding, in particular the Vorverseilung, the first and the second winding material to deduct the second winding material in the withdrawal direction before leadership on the rotor bar of the Rotorbügelablaufsystem of used as a further tangential drainage system of another Rotorbügelablaufsystems.

The or the Rotorbügelablaufsysteme can be arranged horizontally but also vertically.

In use for the reverse rotation of the third winding material, in particular a third wire, the third winding material is passed through the third implementation. After passing through the cylindrical body of revolution, the third winding material is passed over a rotor yoke of a rotor yoke discharge system, using which the third winding material receives a reverse rotation.

Again, the Rotorbügelablaufsystem can be arranged horizontally or vertically.

Next can be provided in the reverse rotation of the third winding material, that the third winding material is deducted in the withdrawal direction before passing through the cylindrical body of rotation of a take-off device of the Rotorbügelablaufsystems.

Preferably, the device, the method or its or its developments can be combined or supplemented with a determination and / or regulation of a winding material tension and / or take-off force for a winding material.

Thus, a first force measuring device, in particular a first load cell, for measuring a tensile force and / or tension in a winding material, can be provided here. About this, the first winding material before passing through the first implementation of the substantially cylindrical Rotational body are guided.

Furthermore, a third force-measuring device, in particular a third load cell, can likewise be provided for measuring a tensile force and / or tension in a winding material. By means of these, a product stranded from the first and the second winding material can be guided after passage through the essentially cylindrical rotary body.

In a further development, a second force measuring device, in particular a second load cell, for measuring a tensile force and / or tension in a winding material can then additionally be provided, via which the second winding material is guided through the second passage of the substantially cylindrical rotational body before passing through.

In the determination and / or regulation of a winding material tension and / or withdrawal force for a winding material, in particular for determining a desired withdrawal force of the second winding material and / or regulation of a second withdrawal force of the second winding material, can now with the first force measuring device, a first withdrawal force of the first winding material and / or with the second force measuring device, a second withdrawal force of the second winding material to be measured.

With the third force measuring device, the tensile force in the stranded product can be measured.

Using the first peel force of the first winding material or the second peel force of the second winding material and the tensile force in the stranded product, the target peel force of the second or first winding material determined and / or the second or first peel force of the second winding material can be controlled.

Fig.1 ) for the merger of - in this case - two individual cores 102 and 103 (see esp. Fig.2 ), which as an integral part of a lower rotor shaft 600 and 600 'of a vertically arranged Rotorbügelablaufsystems, in the Ausfichenungsgemäßen cases of a first 650 and a second 660 Rotorbügelablaufsystems is formed.

It should be noted that the stranding element 100 or 100 'according to the invention, as described here in the case of vertical rotor yoke drainage systems, can be used correspondingly in horizontal rotor yoke drainage systems.

The stranding element 100 or 100 'will, as will be described below in the embodiments and application examples, used in a Vorverseilung (a triple total stranding) of the first 102 and the second 103 core (embodiment / application example 1), used in a reverse rotation a first 102 'or second 103' wire (embodiment / application example 2) and used in the pre-stranding in combination with a wire tension / Abziehskraftregelung for the second wire 103 (embodiment / application example 3).

Overview of application examples

Figure 5 shows an overview of a part 670 of a combined total stranding, which both Vorverseilung the first 102 and the second 103 wires (embodiment / application example 1) as well as for the reverse rotation of the first 102 'or the second 103' core (embodiment / application example 2) as well as also for pre-stranding in combination with the core tension / withdrawal force control for the second core 103 (embodiment / application example 3) is usable.

Described vein voltage control of the embodiment / application example 3 but can also be without the structural details of the embodiment stranding according to application example 1 or embodiment reverse-rotation system according to application example 2 sole object of protection.

First, here are the essential elements of in Figure 5 represented part 670 of the overall stranding - also shown and with reference to the other FIGS. 1 to 4 and Figure 6 - to be discribed.

So shows Figure 5 a first 650 and a second 660 each vertically arranged Rotorbügelablaufsystem executed as a folding system with a rotatable rotor bracket 300 and 300 ', for example, a Quillinder. Guide rollers 301 and 301 'are arranged on the rotor yoke 300 or 300' for the wire guide.

The rotor yoke 300 or 300 'is rotatably supported by a lower 600 or 600' and upper 610 or 610 'rotor shaft and is driven by a drive unit 520 or 520'.

In the lower rotor shaft 600 and 600 'is the stranding 100 and 100' (see. FIGS. 1 to 6 ) or the lower rotor shaft 600 or 600 'is configured in such a way that it simultaneously acts or serves as the stranding element 100 or 100' according to the invention.

Both Rotorbügelablaufsysteme 650, 660 are arranged parallel to each other and synchronized simultaneously - as in Application Example 2 in stranding - operated or driven.

Within the rotational body spanned by the rotatable rotor bracket 300, 300 'and on its rotation axis 310 or 310' is a dancer-controlled drainage system 500 or 500 ', which has a delivery spool 400 or 400' mounted in a creel 401 or 401 ' - / Abwickelspule) arranged.

Rotor yokes 300 or 300 'and unwinding system 500 or 500' can be decoupled from one another by disengaging a rotor yoke drive, as in application example 1 in the reverse rotation mode.

In the stranding operation (see embodiment / application example 1) - the first wire 102 - the first wire 102 'is dancer-controlled in the rewinding operation (see embodiment / application example 2) - and with approximately constant tensile force (cf. - / Application Example 3).

In the stranding operation (see Embodiment 1), the second core 103 - in the reverse rotation mode (see Embodiment 2) - the second core 103 'is also dancer-controlled by the delivery reel 400' and unwound with an approximately constant tensile force (see Embodiment 3).

For the development of the respective vein, corresponding devices such as a guide nipple 410, deflection rollers and guide rollers 421, 431, associated fastening devices 411, 422, 440 are arranged on the respective unwinding system 500 or 500 'or on the respective outflow spool 400 or 400'.

Next are in the system 670, like Figure 5 as well as the FIGS. 1 to 4 and Figure 6 show various wire guide elements, such as guide nipple 501, pulleys and deflecting rollers 510 and guide rollers 301, for guiding the wires 102, 102 'and 103, 103' shown. The deflection rollers and deflection rollers 510 preferably have a running diameter of at least 120 mm in the exemplary embodiments.

To minimize the total wire pull-off forces in the system or in the System 670, a single-disk take-off with a pressure belt and dancer control 530 for the trigger is additionally installed.

Furthermore, both dancer-controlled drainage systems 500 and 500 'of the system 670 each have a device for traction or wire tension measurement, here a first and a second load cells 700 and 701, which - in the drawing direction - immediately after the take-off point of the respective wire 102, 102 'or 103, 103' is mounted in the corresponding rotor bow discharge system 650 or 660. About this first and second load cell 700 and 701, the first 102 and second 103 wire is guided and thereby measured their tensile force and the core voltage.

Furthermore, there is a further, in this case third, load cell 710, which is mounted in the withdrawal direction after the stranding element 100, via which the stranded product is guided out of the first 102 and the second 103 strand (see Example 1) and thereby whose tensile force or wire tension is measured.

Stranding element 100 or 100 '(cf., in particular, FIG. 1 or FIGS. 2 to 6)

The stranding element 100 or 100 '- as part of the lower rotor shaft 600 or 600' - consists, as the FIGS. 1 to 6 show, from an elongated, substantially cylindrical, about a rotational axis 101 rotatably mounted component, which is connected by means of a fastener 302 with the rotatable about the rotation axis 101 rotor bracket 300 or 300 'for common rotation.

For storage of the lower rotor shaft 600 or 600'bzw. the stranding element 100 or 100 'bearing elements 150 and 160 are provided with ball bearings 151 to 154. Furthermore, at the lower end 141 and at the upper end 140 of the lower Rotor shaft 600 or 600'bzw. the Verseilelements 100 and 100 'timing pulleys 170, 171 provided.

The stranding element 100 or 100 'has three bushings or bores 110, 120 and 130 for guiding the first 102 and second 103 strand or the first and second strand 102', 103 '- in the stranding operation as well as in the reverse rotation operation.

The first feedthrough 110, which serves to carry out the first wire 102 in the stranding operation, connects an eccentric or peripheral input 111 on the upper end side or the input end side 140 of the stranding element 100 or 100 'in a parallel path to the axis of rotation 101 with a radial outlet 112 at the lower end side or the output end face 141 of the stranding element 100 or 100 '.

The second feedthrough 120, which serves to carry out the second wire 103 in the stranding operation, connects an input 121 of the stranding element 100, which is approximately centered on the surface 143 of the stranding element 100 or 100 'relative to the longitudinal extension of the stranding element 100 or 100' or 100 'in approximately parallel course to the axis of rotation 101 with a radial outlet 122 on the output end face 141 of the stranding element 100 or 100'. At the entrance 121, a guide roller 123 for guiding the second wire 103 is arranged.

The third feedthrough 130, which serves to carry out the first or second wire 102 'or 103' in the reverse rotation mode, connects a central input 131 on the input end face 140 in an approximately parallel course to the axis of rotation 101 with respect to the longitudinal extent of the stranding element 100 or 100 '- front third on the surface 143 of the stranding 100 or 100' arranged output 132. At the output 132 is a deflection roller 133 for guiding the wires 102'bzw. 103 'arranged.

The course of the cores 102, 103 and 102 ', 103' through the stranding 100 and 100 'in the stranding operation and in the Reverse turning operation is in Fig.1 labeled with reference numerals 105, 106 and 107.

Thus, a two-dot chain line 105 illustrates the course of the first wire 102 through the stranding element 100 in the case of stranding. The three-dot chain line 106 illustrates the course of the second wire 103 through the stranding 100 and 100 'also in the case of stranding.

The four-dot chain line 107 illustrates the course of the wire 102 'or 103' through the stranding element 100 or 100 'in the case of reverse rotation.

EMBODIMENT / APPLICATION EXAMPLE 1: Dancer-regulated drainage system in use as a pre-stranding system or stranding element 100 during the pre-stranding

The above system 670 will now be described in use as a pre-stranding system (for a 3-fold total stranding).

Here, the bow drive is disengaged in the second rotor bow discharge system 660 and the drain system 500 'is used as a "normal" tangential drain.

From this, the second vein 103 dancer-controlled withdrawn with approximately constant tensile force and guided over the standing rotor bracket 300 'of the second rotor yoke discharge system 660.

The first rotor hanger drainage system 650 is likewise used only as a tangential drain, from the drainage system 500 of which the first core 102 is likewise pulled down by the dancer.

The second core 103 is now routed further over the rotor yoke 300 of the first rotor yoke drain system 650.

Both cores 102 and 103 are then - as above or below is or is described in detail - by the stranding 100, which rotates as part of the lower rotor shaft 600 with the rotor yoke 300, guided and thereby fed to the first stranding 220. By the rotation of the rotor yoke 300 of the first rotor yoke drain system 650, the wires 102 and 103, i. the couple stranded.

In addition - not shown - the so vorverseilte pair 220 is fed to a second Verseilpunkt and receives there the second Verseilschlag.

Next, the product is passed through a pair stranding, where it receives the third stranding when leaving the rotor bracket of this pair stranding. This gives the single wire a reverse rotation, usually 33%, depending on the stranding speed in the first stranding.

Fig.1 shows the stranding 100 and 100 ', as used in the pre-stranding of the first 102 and the second 103 core.

Thus, a two-dot chain line 105 illustrates the course of the first wire 102 through the stranding element 100 in the case of Vorverseilung. The three-dot chain line 106 illustrates the course of the second wire 103 in this case.

In the case of the Vorverseilung is now - as the curve 105 shows - the first 102 wire at the input end face 140 at the local radial input 111 in the stranding 100 and lower rotor shaft 600 is performed.

The further guide 110 of the first core 102 runs parallel along the axis of rotation 101 of the stranding element 100 until the core 102 leaves the stranding element 100 via the outlet 112 on the output end face 141.

The second wire 103, whose course is indicated by the stranding element 100 with reference numeral 106, is guided through the second feedthrough 120 of the stranding element 100.

It enters at approximately one input 121 of the stranding element 100 or 100 'arranged centrally on the surface 143 of the stranding element 100 or 100' relative to the longitudinal extent of the stranding element 100 or 100 ', passes through this in an approximately parallel course to the axis of rotation 101 and leaves this at a radial outlet 122 at the output end face 141 of the stranding 100.

At the entrance 121, a guide roller 123 for guiding the second wire 103 is arranged, via which the second wire 103 is guided into the stranding element 100.

Exemplary embodiment 2: Dancer-regulated drainage system in use as a reverse rotation sequence or stranding element 100 or 100 'in the reverse rotation

The above system 670 will now be described in further use as a reverse rotation sequence.

Here, the two vertical and parallel to each other arranged Rotorbügelablaufsysteme 650 and 660 as Rotorbügelablauf, both Rotorbügel Ablaufsysteme are synchronously driven simultaneously.

The two feed-through coils 400 and 400 'of the two rotor hanger drainage systems 650 and 660 are here - in coupling with the respective rotor hanger 300 or 300' - driven by a drive unit 450 and the first core 102 'and the second core 103' are dancer-controlled with approximately constant Pulling power deducted.

The respective withdrawn vein 102 'and 103' is - as above or below is or will be explained in more detail - by the stranding 100 and 100 ', which as part of the the lower rotor shaft 600 and 600 'with the respective rotor bracket 300 and 300' co-rotated, and then guided over the respective rotor bracket 300 and 300 '. Thereby or there it receives a rotation by the rotation thereof.

In addition - not shown - the wires 102 'and 103' fed to a first Verseilpunkt and receive there the first Verseilschlag.

Further, the product is - as part of the pair stranding - led by a pair stranding, where it receives the second stranding when leaving the rotor yoke of this pair stranding. As a result, the rotation is completely or partially unscrewed depending on the Rückdrehprozentente or Rückdrehgrad.

Fig.1 shows the stranding 100 and 100 ', as it is also used in the reverse rotation process. The four-dot chain line 107 illustrates the course of the wire 102 'or 103' through the stranding element 100 or 100 'in the case of reverse rotation.

In the case of the reverse rotation is now - as the curve 107 shows - the first 102 'or second 103' wire at the input end face 140 at the local centric input 131 in the stranding 100 or 100 'or lower rotor shaft 600 and 600' guided.

The further - centric central - guide 130 of the wire 102'bzw. 103 'extends for a predeterminable distance along the axis of rotation 101 of the stranding 100 or 100' until the wire 102 'or 103' via a guide roller 133, the stranding 100 and 100 'via the output 132 in the direction of the rotor yoke 300 and 300 'leaves.

Possibility of controlling the core voltages

For use with a device according to the invention, a wire or wire tension control can be provided.

The aim of the embodiment and hereinafter described wire tension control is the same wire tension in the stranding in both wires in the stranding or pre-stranding.

The execution vein voltage control should thus different core voltages in the two wires, which arise due to different or different lengths of withdrawal lines of the two wires (up to the first stranding point) and the associated different frictional forces on the two wires, compensate.

For the wire tension control, the two rotor bow discharge systems 650, 660 are each equipped with the dancer-controlled deduction of the respective wire (already described above).

Furthermore, both drainage systems 650, 660 each have a device for traction or wire tension measurement, here a first 700 and a second 701 load cell, which - in the drawing direction - immediately after the take-off point of the respective wire in the corresponding (first and second) Rotorbügelablaufsystem 650th , 660 is attached. The first and second wires 102, 103 are guided by way of these first and second load cell 700, 701, respectively, and their tensile force or their wire tension is measured.

Next, the stranding another, in this case, third, load cell 710, which - in the drawing direction is attached after the stranding point 200 of the two cores 102, 103, over which the stranded product 220 (from the first and the second wire 102, 103) is guided and its tensile force or wire tension, hereinafter referred to briefly as product tension or product tensile force, is measured.

In the case of the wire tension control according to the embodiment, a first dancer-controlled withdrawal or unwinding of the first wire 102 with a predefinable or predetermined master / nominal pull-off force F (nominal) takes place in the first rotor hanger drainage system 650 used as a tangential flow.

To set the nominal withdrawal force for the withdrawal of the first wire 102 and to ensure the deduction with a constant nominal withdrawal force, the withdrawal force or wire tension in the first wire 102 is measured immediately after the take-off point in the first drainage system 650 by means of the first load cell 700 and accordingly - if necessary - (automatically during operation) to readjust / retard (F (nominal) = F (deduction 1)).

Next, by means of the third load cell 710, the product tension or the tensile force in the (pre-) stranded product 220 F (product) is measured.

The withdrawal force for the second dancer-controlled withdrawal or development of the second vein 103 F (deduction 2) in the second rotor-hanger expander system 660, which is likewise used as a tangential outlet, can be determined as follows: $$\mathrm{F}\left(\mathrm{deduction}\mathrm{2}\right)\mathrm{=}\mathrm{F}\left(\mathrm{nominal}\right)\mathrm{-}\left(\mathrm{product\; voltage}\mathrm{-}\mathrm{2}\mathrm{*}\mathrm{F}\left(\mathrm{nominal}\right)\right)\mathrm{,}$$

This deduction force for the withdrawal of the second vein 103 determined in this way is set on the dancer-controlled withdrawal of the second outflow system 660 - and monitored analogously to the first outflow system 650 by means of the second load cell 701 or optionally (automatically during operation).

The following numerical example is intended to further clarify the wire voltage regulation. A nominal pull-off force of F (nominal) = 10 N is set on the first dancer-controlled trigger of the first drain system 650.

The force measurement by means of the third load cell 710 provides, for example, a product tensile force of F (Prod) = 27 N.

From this, a withdrawal force for the second, dancer-controlled withdrawal or development of the second strand 103 F (deduction 2) = 3 N can be determined according to the above equation (gel 1). With this pull-off force F (Abzugs 2) = 3 N, the second wire 103 is now deducted. Then F (Prod) = 20 N.

These settings of first and second pull-off forces with F (trigger 1) or F (rated) and F (trigger 2) allow the same core tension during stranding - and thus a high-quality product.

The pull-off force for the second wire 103 is changed (reduced) until the product voltage becomes 2 * F (nominal).

Finally, it should be pointed out again that the described plant - because of their different applications (stranding, reverse rotation, voltage regulation) - is highly flexible.

A production of wire pairs for UTP, FTP, STP and S / STP for the categories 5, 5+, 6 and possibly 7 can be increased by more than 30%.

The use as a normal Rückdrehheinheit- / plant (see Aisführungsbeispiel 2) for high-quality products such as category 8, quad and bus lines is also possible as a Hauptverseilung with reverse rotation 0-100%.
