Definitions
- the present invention relates to an apparatus to be used during the manufacture of a telecommunication, cable including insulated conductors which are twisted together.
- the apparatus is intended to vary, along the cable, the relative positions of the conductors with respect to each other within the cable and comprises a number of wire guides corresponding to the number of conductors which are arranged to guide one conductor each when the conductors are fed into a twisting machine.
- the relative positions of the conductors are changed before they are twisted together so that the conductors coming from stationary bobbins pass wire guides arranged in an outeran an inner circular wire guide carrier which are concentricaly positioned and can be turned 180 around the common axis.
- wire guide carriers By this ability of the wire guide carriers to be turned 180 the number of alternative possibilities for varying the relative position of the conductors will be limited. If a conductor group consists of eight conductors there will consequently be only four alternatives.
- FIG. 1 schematically and partly in perspective shows an embodiment of an arrangement according to the invention for manufacturing a five-wire cable
- FIG. 2 shows a wire guide and a pneumatic device for moving the wire guide.
- reference 1 denotes five bobbins arranged on a floor stand 2.
- Conductors 3, which are to be included in thecable, are rolled on these bobbins. From the bobbins each conductor is drawn through a wire guide 4 and via a pulley wheel 8 to a puller wheel 7 shaped as a planar cylinder, the periphery of which the conductors follow until, via the pulley wheel 9, they bend toward the nozzle 5 of a twisting machine 6.
- each wire guide 4 there is a pneumatic driving device 12, by means of which the wire guide can be activated to take an arbitrary position in a path limited by two outer positions and arranged mainly across the feeding direction of the conductors.
- Reference 11 denotes an endless band, which runs in a path across the puller wheel '7, the two pulley wheels 8 and 9 and a further pulley wheel 10.
- the endless band 11 presses the conductors against the cylindrical surface of the puller wheel, whereby a planar bundle or band of parallel conductors is formed.
- the positons of the wire guides in their respective paths determine the relative positions of the conductors in the planar bundle of conductors and this position will in turn be determining for the relative positions of the conductors in the twisted cable when it is completed.
- FIG. 2 shows a wire guide and a pneumatic device for moving the wire guide.
- the pneumatic device comprises a cylinder 23, in which a movable piston 24 is fixed on one end of a piston rod 22, extending through the cylinder 23 and out through an opening in one end of the cylinder.
- the wire guide 21 is fixed at the end of the piston rod situated outside the cylinder end, the wire guide 21 by means of the pneumatic device being brought to take an arbitrary position between the two outer positions denoted A and B.
- Compressed air tubes are connected to the two ends of the cylinder and the movements of the pis v ton are in a known manner controlled by solenoid valves, not shown in the Figure, connected in these tubes.
- the solenoid valves are controlled for example by means of a programming tape fed into a tape recording device included in a controlling apparatus connected to the solenoid valves.
- a programming tape fed into a tape recording device included in a controlling apparatus connected to the solenoid valves.
- the change of the relative positionsof the conductors may also be controlled by a measuring device measuring important trans-mission data, e.g. the crosstalk, one or several wire guides being actuated when predetermined values or relationships are achieved.
- important trans-mission data e.g. the crosstalk
- Apparatus for manufacturing a telephone cable which includes a plurality of twisted conductors comprising a source of individual conductors,-a conductor twisting means, conveying means for moving individual conductors along individual substantially parallel paths.
- each of said wire guides disposed in the path of the conductors from said source to said twisting machine, each of said wire guides supporting a different one of the conductors, means for selectively and individually moving each of said wire guides to different positions along lines substantially transverse to the substantially parallel paths so that each of the conductors can be directed to an arbitrary position relative to the positions of the other conductors and forming means, downstream from said ductors to form the first planar array.
