Usuellement, un câble se fabrique en plu­sieurs étapes, à savoir d'abord le toronnage de brins élémentaires. Le toron ainsi formé est reçu sur un ca­bestan par exemple de type "Cook'' qui assure à la fois le trancanage et la traction du toron sur une bobine.Usually, a cable is manufactured in several stages, namely first the stranding of elementary strands. The strand thus formed is received on a capstan for example of the "Cook" type which ensures both the cutting and the traction of the strand on a reel.

Puis la bobine qui porte la longueur de câble adéquate est reprise pour faire passer le toron dans une machi­ne de rubanage.Then the coil carrying the appropriate length of cable is taken up to pass the strand through a tape machine.

Il existe également une installation du type ci-dessus comprenant en ligne un poste de toronnage avec une filière de commettage, une tête à rubaner et un cabestan par exemple de type "Cook" qui enroule le câble rubané.There is also an installation of the above type including a stranding station in line with a committing die, a tape head and a capstan, for example of the "Cook" type, which winds the ribbon cable.

Dans cette installation connue les bobines d'émission des brins élémentaires sont fixes dans l'espace et l'ensemble des moyens situé en aval du point de commettage où se forment les torons tourne autour de l'axe de l'installation pour conserver le toronnage et ne pas l'ouvrir jusqu'à son enroulement sur la bobine dans le cabestan. Dans cette installation la tête à rubaner tourne autour de l'axe général en sens opposé de la rotation du toron. L'objectif est d'additionner les vitesses angulaires du toron et de la tête à rubaner en vue d'augmenter la production sans augmenter la vitesse absolue de la tête à rubaner. Comme cela sera expliqué ultérieure­ment, à l'aide des figures 2 et 3, cette rotation en sens opposé de la tête à rubaner et du toron réalise un rubanage hélicoïdal orienté dans le même sens que les hélices du toron.In this known installation, the emission coils of the elementary strands are fixed in space and all of the means located downstream from the committing point where the strands are formed rotates around the axis of the installation to conserve the stranding. and do not open it until it is wound on the spool in the capstan. In this installation the tape head rotates around the general axis in the opposite direction to the rotation of the strand. The objective is to add the angular velocities of the strand and of the tape head in order to increase the production without increasing the absolute speed of the tape head. As will be explained later, with the aid of FIGS. 2 and 3, this rotation in the opposite direction of the tape head and of the strand achieves a helical banding oriented in the same direction as the helices of the strand.

Lorsque la fabrication du câble se fait par des étapes discontinues avec chaque fois reprise sur une bobine, il est possible de rubaner en sens opposé des hélices du toron puisque dans ce cas, lorsque le toron est dévidé de sa bobine pour passer dans la tête de rubanage, le toron n'a pas à tourner autour de l'axe de l'installation. Toutefois, cela se fait à la condition de procéder de manière discontinue et non pas en ligne sur la filière de commettage.When the cable is made in discontinuous steps with each time taken up on a reel, it is possible to tape in opposite directions helices of the strand since in this case, when the strand is unwound from its reel to pass through the head of tape, the strand does not have to rotate around the axis of the installation. However, this is done on the condition of proceeding discontinuously and not online on the committing channel.

Au contraire, si l'on veut rubaner en sens opposé dans l'installation en ligne connue, décrite ci-dessus, il faut que la tête à rubaner tourne dans le même sens que le toron mais à une vitesse qui doit être de l'ordre de grandeur du double de celle du to­ron pour réaliser un rubanage de même pas que le toron mais de sens opposé.On the contrary, if you want to tape in the opposite direction in the known in-line installation described above, the tape head must rotate in the same direction as the strand but at a speed which must be order of magnitude double that of the strand to carry out taping in the same way as the strand but in the opposite direction.

Or, une telle solution n'est pas envisagea­ble si l'on respecte les vitesses de commettage et de rotation du toron utilisables pratiquement dans une telle installation, vitesses qui sont nécessaires pour des raisons économiques de fabrication. En effet, la vitesse de rotation de la tête à rubaner serait irréa­lisable dans des conditions acceptables sur un plan technologique à cause de l'effet de la force centrifu­ge très grande sur la bobine de ruban, sur les freins électromagnétiques tournants de la tête à rubaner ; il en résulterait également le dégraissage des roulements à billes et une déformation de la structure. Enfin, il serait quasiment impossible de conserver un équilibra­ge dynamique correct. Au niveau de la transmission des signaux et de l'alimentation électrique de la tête à rubaner, la vitesse linéaire importante au niveau des ensembles bagues/balais serait un obstacle très grave. De plus, le ruban utilisé pour réaliser le rubanage serait soumis à des effets centrifuges et aérodynami­ques considérables ne permettant pas un rubanage cor­rect.However, such a solution cannot be envisaged if the commuting and rotation speeds of the strand practically usable in such an installation are respected, speeds which are necessary for economic reasons of manufacture. Indeed, the speed of rotation of the tape head would be impracticable under technologically acceptable conditions because of the effect of the very large centrifugal force on the tape reel, on the rotating electromagnetic brakes of the tape head ; it would also result in the degreasing of the ball bearings and a deformation of the structure. Finally, it would be almost impossible to maintain a correct dynamic balancing. At the level of signal transmission and the electrical supply of the tape head, the high linear speed at the level of the ring / brush assemblies would be a very serious obstacle. In addition, the ribbon used to make the taping would be subjected to considerable centrifugal and aerodynamic effects which do not allow correct taping.

Une telle solution consistant à doubler ou augmenter de manière importante la vitesse de la tête à rubaner pour réaliser un rubanage en sens opposé de l'enroulement du toron n'est pas possible dans les installations actuelles.Such a solution consisting of doubling or significantly increasing the speed of the tape head to achieve tape in the opposite direction of the strand winding is not possible in current installations.

La présente invention se propose de créer une installation de câblage permettant de réaliser un câble à brins élémentaires toronnés et à rubanage de sens opposé de l'enroulement du toron, sans que cela ne soit au détriment de la vitesse de fabrication et sans qu'il n'y ait de rupture de charge.The present invention proposes to create a wiring installation making it possible to produce a cable with elementary strands stranded and with ribboning in the opposite direction of the winding of the strand, without this being to the detriment of the speed of manufacture and without it there is no load break.

A cet effet, l'invention concerne une 35 installation du type ci-dessus caractérisée en ce que la tête à rubaner comprend :

  • A - un ensemble extérieur rotatif par rap­port à l'axe général XX′ et comportant des moyens de guidage du câble avant et après le rubanage avec une entrée et une sortie disposées suivant le sens de cir­culation général du câble dans l'installation, sens pris par rapport à l'axe de défilement XX′,
  • B - un ensemble rotatif par rapport à l'axe général XX′, indépendamment de l'ensemble extérieur et comportant un moyen de rubanage, l'entrée et la sortie du câble de cet ensemble intérieur de rubanage étant disposées en sens opposé du sens de défilement général du câble dans l'installation, avec un chemin de ruba­nage entre l'entrée et la sortie de cet ensemble inté­rieur situé suivant l'axe général XX′ mais orienté en sens opposé au sens général de défilement,
  • C - les moyens de guidage du câble de l'en­semble extérieur conduisant celui-ci jusqu'à l'entrée de l'ensemble intérieur et reprenant le câble rubané à la sortie de l'ensemble intérieur pour faire circuler le câble dans l'ensemble intérieur suivant un sens de circulation opposé au sens général de circulation par rapport à l'axe général XX′,
  • D - des moyens de transmission des signaux de commande et d'alimentation des moyens de contrôle et de commande de l'ensemble intérieur de rubanage.
To this end, the invention relates to an installation of the above type, characterized in that the tape head includes:
  • A - an external assembly rotatable relative to the general axis XX ′ and comprising means for guiding the cable before and after the taping with an inlet and an outlet arranged in the general direction of circulation of the cable in the installation, direction taken with respect to the scroll axis XX ′,
  • B - a rotary assembly relative to the general axis XX ′, independently of the external assembly and comprising a taping means, the entry and exit of the cable from this internal taping set being arranged in the opposite direction to the direction of general running of the cable in the installation, with a taping path between the inlet and the outlet of this interior assembly situated along the general axis XX ′ but oriented in the opposite direction to the general running direction,
  • C - the means for guiding the cable of the exterior assembly leading it to the inlet of the interior assembly and taking up the ribbon cable at the outlet of the interior assembly to circulate the cable in the assembly interior in a direction of circulation opposite to the general direction of circulation with respect to the general axis XX ′,
  • D - means for transmitting the control and supply signals for the control and command means of the internal taping assembly.

Ainsi, grâce à l'installation, le câblage se fait en ligne, c'est-à-dire de manière continue sans rupture de charge et avec un rubanage en sens opposé du sens du toronnage. Cela est possible grâce à l'in­version de sens de défilement du toron (déjà rubané ou non par un ruban de même sens que le toron) à l'inté­rieur de la tête de rubanage. En effet, dans cette tête de rubanage qui réalise le rubanage en sens oppo­sé, le toron ou le câble déjà rubané se comporte comme un fil toronné selon un pas inverse. La tête à rubaner peut ainsi tourner à une vitesse usuelle dans cette technique sans qu'il soit nécessaire de recourir à une vitesse de rotation double comme cela serait nécessai­re en théorie si l'on voulait rubaner en sens inverse un toron dans l'installation de câblage connue.Thus, thanks to the installation, the wiring is done in line, that is to say continuously without load break and with tape in the opposite direction of the stranding direction. This is possible thanks to the inversion of the direction of travel of the strand (already or not tape with a ribbon of the same direction as the strand) inside the taping head. Indeed, in this taping head which performs the taping in the opposite direction, the strand or cable already tapeed behaves as a stranded wire in a reverse pitch. The tape head can thus rotate at a usual speed in this technique without the need to resort to a double speed of rotation as would be necessary in theory if one wanted to tape in reverse a strand in the installation of known wiring.

Suivant une autre caractéristique de l'in­vention, l'ensemble extérieur se compose de deux flas­ques entraînés en rotation synchrone et portant l'un des moyens de guidage du câble en amont du moyen de rubanage et l'autre des moyens de guidage du câble en sortie du moyen de rubanage.According to another characteristic of the invention, the exterior assembly consists of two flanges driven in synchronous rotation and carrying one of the cable guide means upstream of the taping means and the other of the cable guide means in exit from the taping means.

Suivant une autre caractéristique de l'in­vention, l'ensemble extérieur comporte un support for­mant une réserve pour recevoir des bobines de ruban.According to another characteristic of the invention, the exterior assembly comprises a support forming a reserve for receiving reels of ribbon.

Suivant une autre caractéristique de l'in­vention, l'ensemble extérieur comporte un tube situé sur l'axe et portant librement en rotation l'ensemble intérieur.According to another characteristic of the invention, the exterior assembly comprises a tube situated on the axis and freely rotating the interior assembly.

Suivant une autre caractéristique de l'in­vention, l'ensemble intérieur se compose d'un premier tube monté par des paliers sur le tube de l'ensemble extérieur, ce premier tube étant muni d'une bride por­tant un organe de freinage assurant le freinage du dé­roulement de la bobine de ruban, elle-même portée par un second tube en libre rotation sur le premier tube.According to another characteristic of the invention, the interior assembly consists of a first tube mounted by bearings on the tube of the exterior assembly, this first tube being provided with a flange carrying a braking member ensuring braking. of the unwinding of the ribbon spool, itself carried by a second tube in free rotation on the first tube.

Suivant une autre caractéristique de l'in­vention, le tube de l'ensemble extérieur et le tube de l'ensemble intérieur portent des bagues coopérant avec des balais appartenant à un équipage muni d'un contre­poids et libre en rotation autour des tubes faisant partie du moyen de transmission.According to another characteristic of the invention, the tube of the exterior assembly and the tube of the interior assembly carry rings cooperating with brushes belonging to a crew provided with a counterweight and free to rotate around the tubes forming part of the means of transmission.

Suivant une autre caractéristique de l'in­vention, le moyen de transmission du mouvement de l'ensemble intérieur à partir de l'extérieur se compo­ se d'une poulie solidaire du tube de l'ensemble inté­rieur et coopérant avec une poulie portée par un axe solidaire en position de l'ensemble extérieur traver­sant le flasque de l'ensemble extérieur et portant à l'extérieur une roue coopérant avec une roue montée libre en rotation sur le tube à l'extérieur de l'en­semble extérieur cette roue étant solidaire d'une roue entraînée par un moteur.According to another characteristic of the invention, the means of transmitting the movement of the interior assembly from the exterior is composed se of a pulley integral with the tube of the interior assembly and cooperating with a pulley carried by a shaft integral in position with the exterior assembly passing through the flange of the exterior assembly and carrying on the outside a wheel cooperating with a wheel free rotationally mounted on the tube outside the exterior assembly, this wheel being integral with a wheel driven by a motor.

Suivant une autre caractéristique de l'in­vention, l'ensemble extérieur comporte un moyen d'en­traînement en rotation formé d'une poulie solidaire du tube de l'ensemble extérieur et entraîné en rotation par un moteur.According to another characteristic of the invention, the exterior assembly comprises a rotational drive means formed by a pulley integral with the tube of the exterior assembly and driven in rotation by a motor.

Suivant une autre caractéristique de l'in­vention, les différents moteurs d'entraînement sont commandés à partir d'un poste central assurant la com­mande en vitesse des différents moyens de toronnage et de rubanage.According to another characteristic of the invention, the various drive motors are controlled from a central station ensuring the speed control of the different stranding and banding means.

Selon l'invention, le moyen de transmission des signaux de l'ensemble intérieur vers l'extérieur à travers l'ensemble extérieur se fait ainsi de manière très simple sans que l'ensemble de contact entre les bagues et les balais ne soit soumis à l'effet des for­ces centrifuges. En effet, les balais sont flottants en position pratiquement fixe puisque cet équipage est monté libre en rotation sur le tube de l'ensemble ex­térieur et sur le tube de l'ensemble intérieur. Seules les bagues sont soumises aux forces centrifuges. En sortie du tube de l'ensemble extérieur, au-delà de l'ensemble extérieur, il est prévu une autre série de bagues coopérant avec des balais fixes reliés au poste de commande.According to the invention, the means of transmitting the signals from the interior assembly to the exterior through the exterior assembly is thus very simple, without the assembly of contact between the rings and the brushes being subjected to the effect of centrifugal forces. Indeed, the brushes are floating in a practically fixed position since this assembly is mounted to rotate freely on the tube of the exterior assembly and on the tube of the interior assembly. Only the rings are subjected to centrifugal forces. At the outlet of the tube from the exterior assembly, beyond the exterior assembly, another series of rings is provided, cooperating with fixed brushes connected to the control station.

La transmission mécanique du mouvement de rotation de l'ensemble intérieur à partir d'un moteur fixe situé à l'extérieur est également indépendant du mouvement de l'ensemble extérieur du fait que la transmission par un axe et des pignons ou des poulies de part et d'autre de la paroi de l'ensemble extérieur rend cet ensemble extérieur "transparent". Cette si­tuation est obtenue si les rapports de transmission donnent globalement un rapport 1. Il est possible de jouer sur ce rapport pour obtenir des effets particu­liers.The mechanical transmission of the rotational movement of the interior assembly from a stationary engine located outside is also independent of the movement of the exterior assembly due to the fact that the transmission by an axis and gears or pulleys on either side of the wall of the exterior assembly makes this exterior assembly "transparent". This situation is obtained if the transmission ratios give a global ratio 1. It is possible to play on this ratio to obtain particular effects.

Selon la figure 1, l'invention concerne une installation de câblage comprenant un poste de toron­nage 1 avec une filière de commettage 2 recevant les brins élémentaires de câble 3a, 3b et 3c, 3d... four­nis par des moyens d'émission 4a, 4b, 4c, 4d, immobi­les dans l'espace. En aval du poste de toronnage, le câble 5 passe éventuellement dans un poste de rubanage 6 qui dépose un ruban dans le sens du toronnage puis le câble 7 ainsi rubané passe dans une tête à rubaner 8 qui assure un rubanage en sens opposé du toronnage ou du rubanage réalisé par la tête à rubaner 6. En sortie de la tête à rubaner 8, le câble 9 passe dans un moyen de réception 10 dans lequel le câble est tiré et trancané sur une bobine.According to FIG. 1, the invention relates to a wiring installation comprising a stranding station 1 with a committing die 2 receiving the elementary strands of cable 3a, 3b and 3c, 3d ... supplied by emission means 4a, 4b, 4c, 4d, motionless in space. Downstream of the stranding station, the cable 5 possibly passes through a tape station 6 which deposits a ribbon in the direction of the stranding then the cable 7 thus bandaged passes through a banding head 8 which provides banding in the opposite direction to the stranding or the ribboning carried out by the banding head 6. At the outlet of the banding head 8, the cable 9 passes through a receiving means 10 in which the cable is pulled and cut through on a reel.

Les différents moyens ci-dessus, c'est-à-­dire le poste de toronnage 1, la tête à rubaner 6, la tête à rubaner 8 et le moyen de réception 10 sont si­tués sur un axe X-X′ et tournent le cas échéant autour de cet axe X-X′ ; le défilement général du câble se fait selon la figure 1 de la gauche vers la droite, c'est-à-dire dans le sens X-X′. Ce défilement général fait abstraction du défilement particulier du câble dans tel ou tel poste qui, comme cela sera exposé ci-­aprés, est différent du sens X-X′ et est localement inversé c'est-à-dire dans le sens X′-X.The different means above, that is to say the stranding station 1, the tape head 6, the tape head 8 and the receiving means 10 are located on an axis XX ′ and, if necessary, rotate around from this axis XX ′; the general scrolling of the cable is done according to Figure 1 from left to right, that is to say in the direction X-X ′. This general scrolling disregards the particular scrolling of the cable in such or such station which, as will be explained below, is different from the direction X-X ′ and is locally reversed, that is to say in the direction X′-X.

De manière plus détaillée, la tête à rubaner 8 se compose d'un ensemble extérieur 81 rotatif par rapport à l'axe X-X′ comportant des moyens de guidage du câble 7 avant et après le rubanage ; cet ensemble extérieur a une entrée 82 et une sortie 83 disposées dans le sens général de circulation du câble dans l'installation.In more detail, the tape head 8 consists of an outer assembly 81 rotatable relative to the axis X-X ′ comprising means for guiding the cable 7 before and after the tape; this external assembly has an inlet 82 and an outlet 83 arranged in the general direction of circulation of the cable in the installation.

La tête comporte également un ensemble inté­rieur 84 également rotatif par rapport à l'axe X-X′ mais indépendamment de la rotation de l'ensemble exté­rieur 81. Cet ensemble intérieur est muni d'un moyen de rubanage 85.The head also includes an interior assembly 84 also rotatable relative to the axis X-X ′ but independently of the rotation of the exterior assembly 81. This interior assembly is provided with a taping means 85.

L'entrée 86 et la sortie 87 du câble de cet ensemble intérieur de rubanage 84 sont disposées en sens opposé du sens de défilement général du câble, c'est-à-dire que l'entrée 86 se situe du côté X′ et la sortie 87 du côté X. Entre l'entrée 86 et la sortie 87 on a le chemin de rubanage 88, à ce niveau le ruban 89, fourni par le moyen de rubanage 85, passe au tra­vers d'une fente de l'ensemble 84 et s'enroule autour du câble en sens opposé du sens de toronnage.The inlet 86 and the outlet 87 of the cable of this internal tape assembly 84 are arranged in the opposite direction to the general direction of travel of the cable, that is to say that the inlet 86 is located on the X ′ side and the exit 87 on the X side. Between entry 86 and exit 87 there is the tape path 88, at this level the tape 89, supplied by the tape means 85, passes through a slot in the assembly 84 and is wound around the cable in the opposite direction to the direction of stranding.

Il convient de noter qu'il est possible d'imaginer d'autres circuits de toron dans la partie 8 pour inverser le sens de l'hélice de rubanage, le cir­cuit représenté sur la figure 1 ou sur les figures 5B et 6 étant cependant le plus simple.It should be noted that it is possible to imagine other strand circuits in part 8 to reverse the direction of the taping helix, the circuit shown in FIG. 1 or in FIGS. 5B and 6 being however the simpler.

La tête à rubaner est également munie d'un moyen de transmission des signaux de commande et d'a­limentation reliant l'extérieur de la tête à l'ensem­ble intérieur de rubanage 82, c'est-à-dire au moyen de contrôle et de commande du fonctionnement de cet en­semble intérieur 84, à travers l'ensemble extérieur 81 qui devient "transparent" cela signifie que ces moyens de transmission relient le moyen intérieur 84 à l'extérieur indépendamment du sens de rotation et de la vitesse de rotation de l'ensemble extérieur 81 et de l'ensemble intérieur 84.The taping head is also provided with a means of transmitting the control and supply signals connecting the outside of the head to the inside taping assembly 82, that is to say by means of monitoring and control of the operation of this interior assembly 84, through the exterior assembly 81 which becomes "transparent" this means that these transmission means connect the interior means 84 to the exterior independently of the direction of rotation and of the speed of rotation of the exterior assembly 81 and interior assembly 84.

Les figures 2 et 3 montrent schématiquement le principe du rubanage classique consistant à réali­ser en aval de la filière de toronnage un rubanage dans le sens du toronnage, rubanage qui est réalisé par la tête à rubaner 6.FIGS. 2 and 3 schematically show the principle of conventional taping consisting in making downstream of the stranding die a tapering in the direction of stranding, taping which is carried out by the taping head 6.

Par convention sur les dessins, le câble 5 circule d'avant en arrière en s'éloignant de l'oeil 0 de l'observateur. Le câble 5, toronné, tourne sur lui-­même dans le sens de la fléche circulaire A. Par con­tre, le ruban 100 dévidé par la tête de rubanage re­présentée par la poulie de renvoi 101 tourne dans le sens de la flèche B, c'est-à-dire en sens opposé du sens de rotation du toron 5. Le ruban se dépose ainsi sur le toron 5 comme cela apparaît dans la partie droite de la figure 3. On voit ainsi que le ruban for­ me une hélice de même sens que les hélices du toron 5, le pas pouvant toutefois être différent.By convention on the drawings, the cable 5 circulates from front to back away from the eye 0 of the observer. The stranded cable 5 turns on itself in the direction of the circular arrow A. On the other hand, the ribbon 100 unwound by the tape head represented by the return pulley 101 rotates in the direction of the arrow B, c ' that is to say in the opposite direction of the direction of rotation of the strand 5. The ribbon is thus deposited on the strand 5 as it appears in the right part of FIG. 3. It is thus seen that the ribbon for me a propeller in the same direction as the propellers of the strand 5, the pitch may however be different.

La figure 4 montre schématiquement le ruba­nage exécuté par la tête à rubaner 8 de la figure 1.FIG. 4 schematically shows the taping carried out by the taping head 8 of FIG. 1.

Les mêmes conventions d'orientation que ci-­dessus ont été utilisées dans la figure 4. L'orienta­tion est donnée par l'oeil 0 de l'observateur et les références de la figure 1 ont été utilisées dans cette figure 4 pour désigner les mêmes éléments.The same orientation conventions as above were used in FIG. 4. The orientation is given by the observer's eye 0 and the references in FIG. 1 have been used in this FIG. 4 to designate the same elements.

Selon la figure 4, le câble 7 qui vient par exemple de la tête à rubaner 6 (selon la figure 3) et qui tourne toujours dans le sens de la flèche circu­laire A, est dévié par les moyens de guidage 102, 103, 104, 105 de l'ensemble extérieur (non représentés) en­tre l'entrée 82 de l'ensemble extérieur et l'entrée 86 de l'ensemble intérieur. Les spires des torons ont été représentées sur le câble 7.According to FIG. 4, the cable 7 which, for example, comes from the tape head 6 (according to FIG. 3) and which always rotates in the direction of the circular arrow A, is deflected by the guide means 102, 103, 104, 105 of the exterior assembly (not shown) between the inlet 82 of the exterior assembly and the inlet 86 of the interior assembly. The turns of the strands have been shown on the cable 7.

Au niveau du chemin de rubanage, du fait de la rotation de l'ensemble extérieur, le câble 7 tourne toujours dans le sens de la flèche A.At the level of the taping path, due to the rotation of the external assembly, the cable 7 always rotates in the direction of arrow A.

L'ensemble intérieur assurant le rubanage tourne dans le sens de la flèche B opposé au sens de la flèche A. Le ruban 89 est ainsi placé autour du câ­ble 7 pour donner le câble 9 ; celui-ci est guidé par les moyens de guidage 106, 107, 108, 109, vers la sor­tie 83 de l'ensemble extérieur. Cette figure montre clairement que l'hélice formée par le ruban 89 sur le câble 9 est opposée aux hélices des torons et le cas échéant du ruban du ou des postes de rubanage amont(s).The internal assembly ensuring the taping rotates in the direction of arrow B opposite the direction of arrow A. The tape 89 is thus placed around the cable 7 to give the cable 9; the latter is guided by the guide means 106, 107, 108, 109, towards the outlet 83 of the exterior assembly. This figure clearly shows that the helix formed by the ribbon 89 on the cable 9 is opposite to the helices of the strands and, where appropriate, of the ribbon of the upstream taping station (s).

La figure 3 montre clairement que le toron 5 et le rubanage se font par une rotation en sens opposé pour aboutir à un rubanage enroulé dans le même sens que le toron.Figure 3 clearly shows that the strand 5 and the tape are made by a rotation in opposite direction to result in a tape wound in the same direction as the strand.

Si dans les conditions de la figure 3 on voulait rubaner en sens opposé du toron, il faudrait faire tourner (par des pas de toronnage et de rubanage opposés) la tête à rubaner à une vitesse de rotation de même sens mais d'amplitude de l'ordre de grandeur du double de celle du toron. Or cela est impossible.If under the conditions of figure 3 we wanted to tape in the opposite direction of the strand, it would be necessary to rotate (by opposite stranding and tape) the tape head at a speed of rotation of the same direction but of amplitude of the order of magnitude double that of the strand. This is impossible.

La solution à cette difficulté est le re­tournement du sens de défilement du câble ou du toron (figure 4), qui permet par un toronnage dans un sens de rotation et un mouvement de la tête à rubaner dans le sens opposé, d'aboutir à un ruban enroulé en sens opposé du toron.The solution to this difficulty is the reversal of the direction of travel of the cable or the strand (FIG. 4), which allows by stranding in a direction of rotation and a movement of the tape head in the opposite direction, to lead to a ribbon wound in the opposite direction to the strand.

Les figures 5A, 5B, 5C, destinées à être combinées dans cet ordre suivant l'axe X-X′ représen­tent une installation de câblage plus détaillée qu'à la figure 1.FIGS. 5A, 5B, 5C, intended to be combined in this order along the axis X-X ′ represent a more detailed wiring installation than in FIG. 1.

Selon la figure 5A, le poste de toronnage 1 montre la filière de commettage 2 qui reçoit les brins élémentaires de câble 3a, 3b, 3c, 3d ... Comme la filière 2 tourne autour de l'axe X-X′ suivant une vi­tesse de rotation choisie en fonction de la vitesse défilement du câble et du pas à réaliser, on obtient en sortie de la filière le câble 5 toronné. Cette fi­lière comporte des poulies de renvoi 201, 202 formant un embarrage qui bloque le point de réunion des brins élémentaires et conserver ainsi une torsion précise du toron en aval de ce moyen. De plus, la poulie 203 est montée sur le bras 204 flexible d'un capteur de tension 205. L'écartement du bras 204 par rapport au capteur 205 permet de déterminer la tension du câble 5. Cette figure montre également les paliers 206 et 207 dans lesquels tourne la filière ainsi que les bagues 208 pour la transmission vers l'extérieur des signaux fournis par le capteur 205. L'entraînement en rotation de la filière 2 est assuré par une couronne dentée 209 qui est reliée à un pignon moteur 210 en­ traîné par un moteur 211 ou un arbre général de dis­tribution de mouvement, par une courroie crantée. La commande du moteur 211 est assurée par un poste central de synchronisation qui reçoit les différents signaux de consigne ou de mesure pour asservir la vitesse du moteur 211 en fonction du toronnage à réaliser.According to FIG. 5A, the stranding station 1 shows the committing die 2 which receives the elementary strands of cable 3a, 3b, 3c, 3d ... As the die 2 rotates around the axis XX ′ according to a speed of rotation chosen as a function of the cable running speed and the pitch to be produced, the stranded cable 5 is obtained at the outlet of the die. This die includes return pulleys 201, 202 forming a tie-down which blocks the meeting point of the elementary strands and thus preserves a precise twist of the strand downstream of this means. In addition, the pulley 203 is mounted on the flexible arm 204 of a tension sensor 205. The spacing of the arm 204 relative to the sensor 205 makes it possible to determine the tension of the cable 5. This figure also shows the bearings 206 and 207 in which the die rotates as well as the rings 208 for the transmission to the outside of the signals supplied by the sensor 205. The rotation drive of the die 2 is ensured by a ring gear 209 which is connected to a motor pinion 210 in trailed by a 211 motor or a general motion distribution shaft, by a toothed belt. The motor 211 is controlled by a central synchronization station which receives the various setpoint or measurement signals to control the speed of the motor 211 according to the stranding to be carried out.

En aval du poste de toronnage 1, la figure 5A montre la tête à rubaner 6. Cette tête à rubaner se compose d'une partie rotative 212 portant le moyen de rubanage 213. Le moyen de rubanage 213 est formé par un manchon monté libre en rotation sur le tube 212 par l'intermédiaire de paliers. Le manchon porte une couronne 214 coopérant avec la couronne 215 qui est en fait le stator d'un frein électromagnétique à poudre. Le manchon 213 reçoit une bobine 216 de ruban. Le moyen de dévidage connu du ruban n'est pas représenté. L'entraînement en rotation du tube 212 est assuré par une couronne dentée 217 et une courroie crantée 218 entraînée par la couronne ou la poulie 219 d'un moteur 220 dont la vitesse de rotation est asservie sur une vitesse de consigne en vue de réaliser le pas de ruba­nage demandé. Cette tête à rubaner 6 fonctionne comme indiqué ci-dessus et comme cela a été décrit à l'aide des figures 2 et 3 : le ruban déposé sur le toron cor­respond à une hélice de même orientation que les héli­ces du toron.Downstream of the stranding station 1, FIG. 5A shows the taping head 6. This taping head consists of a rotating part 212 carrying the taping means 213. The taping means 213 is formed by a sleeve mounted free in rotation on the tube 212 by means of bearings. The sleeve carries a crown 214 cooperating with the crown 215 which is in fact the stator of an electromagnetic powder brake. The sleeve 213 receives a reel 216 of ribbon. The known means of unwinding the ribbon is not shown. The tube 212 is driven in rotation by a toothed ring 217 and a toothed belt 218 driven by the crown or the pulley 219 of a motor 220 whose speed of rotation is controlled by a set speed in order to achieve the no tape required. This tape head 6 operates as indicated above and as has been described with the aid of FIGS. 2 and 3: the ribbon deposited on the strand corresponds to a helix of the same orientation as the helices of the strand.

En sortie, la tête à rubaner 6, est munie d'un support 221 fixe, traversé par le câble 7. Le support reçoit, avant la mise en route de la machine et l'enfilage du câble, une ou plusieurs bobines 222 de réserve. Lorsque la bobine de la tête 6 est épui­sée, on détruit le noyau porteur de la bobine épuisée et on glisse la bobine pleine du support 221 sur le manchon 213.At the outlet, the taping head 6 is provided with a fixed support 221, crossed by the cable 7. The support receives, before the machine is started and the cable is threaded, one or more reserve coils 222 . When the coil of the head 6 is exhausted, the carrier core of the exhausted coil is destroyed and the full coil of the support 221 is slid over the sleeve 213.

La tête à rubaner 8 représentée à la figure 5B se compose de l'ensemble extérieur 81 formé par deux flasques d'extrémité 222, 223 portant des élé­ments périphériques 224 de manière à former une cage. Ce type de réalisation peut être remplacé par deux flasques d'extrémité 330, 331 (voir figure 6) portés chacun par deux paliers 332, 333, entraînés en mouve­ment de façon synchrone et commandés en phase pour une transmission extérieure comprenant un arbre de trans­mission 334 et des liaisons à poulies et courroies 335 et 336. Les barres 224 peuvent alors être remplacées par de simples lames porteuses 337 des moyens de gui­dage 338 (filières) du câble.The tape head 8 shown in Figure 5B consists of the outer assembly 81 formed by two end flanges 222, 223 carrying peripheral elements 224 so as to form a cage. This type of embodiment can be replaced by two end flanges 330, 331 (see FIG. 6) each carried by two bearings 332, 333, driven in synchronous movement and controlled in phase for an external transmission comprising a transmission shaft 334 and pulley and belt connections 335 and 336. The bars 224 can then be replaced by simple carrying blades 337 of the guide means 338 (dies) of the cable.

Cet ensemble extérieur qui tourne autour de l'axe X-X′ dans des paliers 225, 226, est entraîné en rotation par une couronne 227 (poulie) reliée à la poulie 228 d'un moteur 229 par une courroie crantée 230. La rotation du moteur 229 est commandée par la commande centrale et doit être synchrone du moteur 211. On peut également se relier par courroie crantée à l'arbre général de distribution de mouvement déjà évoqué.This external assembly which rotates around the axis XX ′ in bearings 225, 226, is rotated by a crown 227 (pulley) connected to the pulley 228 of a motor 229 by a toothed belt 230. The rotation of the motor 229 is controlled by the central control and must be synchronous with the motor 211. It is also possible to connect by toothed belt to the general movement distribution shaft already mentioned.

L'ensemble extérieur 81 comprend également l'entrée 82 constituée par deux poulies 231, 232 qui dévient le câble 7 vers la périphérie extérieure de la tête 8. Ces poulies 231, 232 peuvent également être considérées comme appartenant aux moyens de guidage du câble dans l'ensemble extérieur (moyen de guidage 102, 103, 104, 105 de la figure 4). Ces moyens de guidage sont complétés dans le mode de réalisation de la figu­re 5B par deux autres poulies 233 et 234 qui ramènent le câble 7 sur l'axe X-X′ mais de façon que le sens de défilement du câble soit à ce niveau opposé au sens de défilement général. Ce sens de défilement du câble est représenté par la flèche D alors que le sens général de défilement du câble est représenté par la flèche C.The external assembly 81 also includes the inlet 82 constituted by two pulleys 231, 232 which deflect the cable 7 towards the external periphery of the head 8. These pulleys 231, 232 can also be considered as belonging to the means for guiding the cable in the external assembly (guide means 102, 103, 104, 105 of FIG. 4). These guide means are supplemented in the embodiment of Figure 5B by two other pulleys 233 and 234 which bring the cable 7 on the axis XX 'but so that the direction of travel of the cable is at this level opposite to the direction general scrolling. This direction of travel of the cable is represented by arrow D while the general direction cable travel is represented by arrow C.

En aval du moyen de guidage 234 qui consti­tue en même temps l'entrée (référence 82) de l'ensem­ble intérieur 84, le câble décrit le chemin de rubana­ge 88 et en sortie de l'ensemble intérieur 84 le câble passe dans une réserve 235 de bobine de ruban pour quitter de nouveau l'axe X-X′ en passant sur une pou­lie 236 qui dévie le câble vers l'extérieur puis une poulie de renvoi 237 et les poulies 238, 239 qui gui­dent le câble rubané 9 vers la sortie. Cette sortie 83 est par exemple constituée par la poulie 239.Downstream of the guide means 234 which at the same time constitutes the inlet (reference 82) of the interior assembly 84, the cable describes the tape path 88 and at the outlet of the interior assembly 84 the cable passes through a reserve 235 reel of tape to leave the axis XX ′ again, passing over a pulley 236 which deflects the cable outwards, then a return pulley 237 and the pulleys 238, 239 which guide the ribbon cable 9 towards the outlet. This outlet 83 is for example constituted by the pulley 239.

Cette réserve de bobines de ruban sera de préférence réalisée de la manière représentée sur la figure 6 suivant laquelle le flasque 330 comporte un manchon coaxial 340 traversé par le câble, ce manchon supportant sur sa face externe, par l'intermédiaire de roulements, un tube 341 recevant les bobines de ruban. Ce tube présente localement une masse pesante 342 for­mant contrepoids maintenant ce tube et les bobines de ruban suivant la même position angulaire sur le man­chon tournant 340. Cela évite la mise en rotation des bobines pleines non encore utilisées en réduisant ain­si les vibrations et, donc, l'usure de l'ensemble de l'installation.This reserve of ribbon reels will preferably be produced in the manner shown in FIG. 6 according to which the flange 330 comprises a coaxial sleeve 340 crossed by the cable, this sleeve supporting on its external face, by means of bearings, a tube 341 receiving the reels of ribbon. This tube locally has a heavy mass 342 forming a counterweight holding this tube and the ribbon coils in the same angular position on the rotating sleeve 340. This avoids the rotation of the full coils which have not yet been used, thereby reducing vibrations and, therefore, wear and tear of the entire installation.

L'ensemble extérieur 81 (figure 5b) comporte également un tube de guidage et de support 240 autour duquel tourne l'ensemble intérieur 84 par l'intermé­diaire du palier 241 représenté schématiquement. L'en­semble intérieur 84 se compose d'un tube 242 muni d'une couronne 243 portant le frein 245, constitué par exemple par un frein électromagnétique. Le tube 242 monté en rotation autour du tube 240 est entraîné à partir de l'extérieur par un moyen décrit ultérieure­ment. Le tube 242 porte, libre en rotation, un tube 246 muni d'une collerette 247 constituant le rotor du frein 245. Le tube 246 reçoit la bobine de ruban 248.The exterior assembly 81 (FIG. 5b) also includes a guide and support tube 240 around which the interior assembly 84 rotates by means of the bearing 241 shown diagrammatically. The interior assembly 84 consists of a tube 242 provided with a crown 243 carrying the brake 245, constituted for example by an electromagnetic brake. The tube 242 rotatably mounted around the tube 240 is driven from the outside by a means described later. The tube 242 carries, free in rotation, a tube 246 provided with a flange 247 constituting the rotor of the brake 245. The tube 246 receives the ribbon spool 248.

L'alimentation du frein 245 et sa commande se font par le moyen de transmission des signaux de commande et d'alimentation constitué par un équipage 249 "tournant" autour des tubes 240, 242. En fait, ce moyen de transmission se compose d'un équipage 249 avec un contre-poids 250 maintenant l'équipage en po­sition immobile par rapport à l'espace, tout en per­mettant la rotation des tubes 240 et 242 suivant des rotations de sens et de vitesses quelconques. De façon complémentaire, les tubes 240 et 242 comportent exté­rieurement des bagues de contact 251, 252, 253, 254, qui coopèrent avec des balais de contact 261, 262, 263, 264 reliés le cas échéant par des conducteurs. On évite ainsi les effets de la force centrifuge sur les balais puisque ces balais sont immobiles dans l'espace et que seuls les bagues 251, 252, 253, 254 tournent pour transmettre ainsi les signaux de l'ensemble inté­rieur à l'ensemble extérieur ou inversement.The supply of the brake 245 and its control are done by the means of transmission of the control and supply signals constituted by a crew 249 "rotating" around the tubes 240, 242. In fact, this means of transmission consists of a crew 249 with a counterweight 250 keeping the crew in a stationary position relative to the space, while allowing the rotation of the tubes 240 and 242 according to rotations of any direction and speeds. In a complementary manner, the tubes 240 and 242 externally comprise contact rings 251, 252, 253, 254, which cooperate with contact brushes 261, 262, 263, 264 connected if necessary by conductors. This avoids the effects of centrifugal force on the brushes since these brushes are stationary in space and only the rings 251, 252, 253, 254 rotate to thus transmit the signals from the interior assembly to the exterior assembly or Conversely.

Le moyen de transmission 90 est complété par une transmission à poulie formée d'un axe 270 parallé­le à l'axe X-X′ et solidaire en rotation de l'ensemble extérieur 81 en étant monté dans un palier 271 de cet ensemble. L'une des extrémités de cet axe 270 porte une poulie 272 coopérant avec une poulie 273 solidaire en rotation du tube 242 de l'ensemble intérieur 84. L'autre extrémité de l'axe 270 est munie d'une poulie 274 qui engrène avec une poulie 275 portée par un en­semble tournant librement par rapport à l'ensemble ex­térieur 81 et comportant une autre poulie dentée 276 entraînée par la poulie 277 de sortie du moteur 278. La vitesse de rotation du moteur 278 est commandée.The transmission means 90 is completed by a pulley transmission formed by an axis 270 parallel to the axis X-X ′ and integral in rotation with the external assembly 81 while being mounted in a bearing 271 of this assembly. One end of this axis 270 carries a pulley 272 cooperating with a pulley 273 integral in rotation with the tube 242 of the interior assembly 84. The other end of the axis 270 is provided with a pulley 274 which meshes with a pulley 275 carried by an assembly rotating freely with respect to the external assembly 81 and comprising another toothed pulley 276 driven by the pulley 277 for outputting the motor 278. The speed of rotation of the motor 278 is controlled.

On peut ainsi transmettre à l'ensemble inté­rieur 84, la vitesse de rotation voulue, quelle que soit par ailleurs la vitesse de rotation de l'ensemble extérieur 81.It is thus possible to transmit to the interior assembly 84, the desired speed of rotation, regardless of the speed of rotation of the assembly. exterior 81.

La transmission des signaux entre le poste central fixe est assurée par des bagues 278 coopérant avec des balais collecteurs 279 non représentés.The transmission of signals between the fixed central station is ensured by rings 278 cooperating with collecting brushes 279 not shown.

On notera également (voir figures 5b et 6) que les galets 234 et 236 situés en amont et en aval de la zone de rubanage, dans le sens de défilement du câble, sont montés sur les flasques 222, 223, respec­tivement 331, 330, par des lames de ressort 350, 351, disposées à proximité de capteurs 352, 353, ces cap­teurs produisant un signal fonction du déplacement des lames 350, 351, et donc un signal fonction de la ten­sion s'exerçant sur le câble en amont et en aval de la zone de rubanage. Ces moyens sont alors traités par un ensemble calculateur afin que par leur différence et compte tenu du pas d'enroulement du ruban, on obtienne une information sur la tension du ruban enroulé sur le toron. Il est alors possible de réguler la tension d'enroulement du ruban. On remarquera par ailleurs que le signal mesuré par le capteur amont 352 est fonction de la tension du toron à la sortie du poste situé di­rectement en aval. Cette disposition est donc particu­lièrement importante dans le cas d'installations com­portant plusieurs têtes d'enrubannage disposées les unes à la suite des autres. Le nombre d'ensemble de mesure à capteur pourra donc être de N + 1 et non pas 2 N (N représentant le nombre de têtes mises en oeu­vre).It will also be noted (see FIGS. 5b and 6) that the rollers 234 and 236 located upstream and downstream of the banding zone, in the direction of travel of the cable, are mounted on the flanges 222, 223, respectively 331, 330, by spring blades 350, 351, arranged near sensors 352, 353, these sensors producing a signal which is a function of the displacement of the blades 350, 351, and therefore a signal which is a function of the tension exerted on the cable upstream and in downstream of the taping area. These means are then processed by a computer assembly so that, by their difference and taking into account the pitch of winding of the ribbon, information is obtained on the tension of the ribbon wound on the strand. It is then possible to regulate the ribbon winding tension. Note also that the signal measured by the upstream sensor 352 is a function of the strand voltage at the output of the station located directly downstream. This arrangement is therefore particularly important in the case of installations comprising several wrapping heads arranged one after the other. The number of sensor measurement sets could therefore be N + 1 and not 2 N (N representing the number of heads used).

Dans le mode de réalisation des figures 5A-­5C, en sortie de la tête à rubaner 8 le câble 9 passe directement dans le moyen de réception 10 constitué par un poste de trancanage portant une bobine 300 mon­tée sur un guide cannelé 301 dont le mouvement de translation alterné dans le sens de la double flèche E est commandé par l'intermédiaire du bras 302 et de la vis mère 303 entraînée en rotation par un moteur 304 par l'intermédiaire d'une transmission à poulie 305, 306 et d'une courroie 307. Ce bras 302 est guidé en translation par une douille 308 coulissant sur l'axe 309. Le palier 301 est un palier cannelé monté sur un axe cannelé 310 porté par des paliers 311 et entraîné en rotation par un ensemble à poulie 312, courroie 313, poulie 314 de sortie du moteur 315. La rotation de ce moteur 315 est également commandée.In the embodiment of FIGS. 5A-5C, at the outlet of the tape head 8 the cable 9 passes directly into the receiving means 10 constituted by a cutting station carrying a reel 300 mounted on a grooved guide 301 whose movement of alternating translation in the direction of the double arrow E is controlled via the arm 302 and the lead screw 303 driven in rotation by a motor 304 via a pulley transmission 305, 306 and a belt 307. This arm 302 is guided in translation by a sleeve 308 sliding on the axis 309. The bearing 301 is a grooved bearing mounted on a grooved axis 310 carried by bearings 311 and driven in rotation by a pulley assembly 312, belt 313, pulley 314 for output of the motor 315. The rotation of this motor 315 is also controlled.

Le câble 9 passe dans le poste 10 sur des poulies de renvoi 320, 321, 322 pour arriver sur la bobine 300 qui se déplace comme déjà indiqué dans le sens de la double flèche E tout en tournant pour réaliser le trancannage du câble sur la bobine 300.The cable 9 passes into the station 10 on pulleys 320, 321, 322 to arrive on the reel 300 which moves as already indicated in the direction of the double arrow E while turning to carry out the cutting of the cable on the reel 300.

Les différents moteurs d'entraînement en ro­tation sont commandés en phase et en synchronisme à partir d'un poste central non représenté qui tient compte des paramètres de l'installation et des consignes (pas du toron, pas des différents rubanages etc..).The various rotary drive motors are controlled in phase and in synchronism from a central station, not shown, which takes account of the installation parameters and instructions (no strand, no different tapes, etc.).

Enfin, il convient de souligner que le nom­bre de tête de rubanage n'est pas limité à celui de l'exemple décrit ci-dessus et également que le moyen de réception peut être à cage fermée comme dans la ré­alisation d'origine "Cook".Finally, it should be emphasized that the number of taping heads is not limited to that of the example described above and also that the receiving means can be with a closed cage as in the original embodiment "Cook" .

Par ailleurs, le poste de toronnage 1, au lieu de ne recevoir que des brins élémentaires 3a, 3d, pourra être conçu pour recevoir également un toron partiellement réalisé afin d'être terminé à ce poste 2 par adjonction soit de brins élémentaires, soit d'au­tres torons. Ce toron partiellement réalisé pourra être émis, soit statiquement, soit par l'intermédiaire d'un neutraliseur, connu en lui-même, ayant pour but d'adapter de manière déterminée la rotation de ce to­ron partiellement réalisé sur lui-même en fonction du mouvement général de la machine.Furthermore, the stranding station 1, instead of receiving only elementary strands 3a, 3d, could be designed to also receive a partially made strand in order to be finished at this station 2 by adding either elementary strands or 'other strands. This partially produced strand can be emitted, either statically, or by means of a neutralizer, known in itself, intended to adapt in a determined manner the rotation of this partially made strand on itself as a function of the general movement of the machine.
