Description

La présente invention concerne une machine perfectionnée permettant de réaliser des fils selon la technique dite par "autotorsion".The present invention relates to an improved machine making it possible to produce wires using the so-called "self-twisting" technique.

La technique qui consiste à réaliser des fils autotordus est connue depuis longtemps et consiste, d'une manière générale, à réunir au moins deux fils dont l'un au moins présente une torsion alternée sur sa longueur de telle sorte que, lorsqu'ils sont mis côte à côte, il s'enroulent l'un autour de l'autre. De préférence, les deux fils sont à torsion alternée, les zones de torsion de même sens étant soit en phase, soit légèrement déphasées, l'une par rapport à l'autre.The technique which consists in making self-twisted yarns has been known for a long time and generally consists in bringing together at least two threads, at least one of which has an alternating twist along its length so that, when they are put side by side, they wrap around each other. Preferably, the two wires are with alternating torsion, the torsion zones of the same direction being either in phase, or slightly out of phase, with respect to each other.

Une telle technique est décrite notamment dans le brevet français 1 405 219 (USP 3 225 533) et ne sera pas décrite en détail. Elle est utilisée pour traiter aussi bien des fils à filaments continus que des filés de fibres, voire, comme cela est décrit dans le brevet des Etats-Unis d'Amérique n£ 4 033 102 des fils autotordus dont au moins l'un des constituants présente une âme dans sa partie centrale. Si cette technique a connu un développement industriel certain depuis de nombreuses années, il faut cependant reconnaître que les machines d'autotorsion commercialisées à ce jour ne répondent pas pleinement aux désirs des utilisateurs. En effet, ces machines sont très spécialisées, comportent un nombre peu élevé de positions de travail et sont difficilement utilisables pour traiter de manière satisfaisante des matières textiles de nature différente et/ou pour y adapter des dispositifs annexes, tels que des moyens de texturation et/ou d'étirage, permettant de produire des fils présentant des propriétés et/ou des caractéristiques différentes.Such a technique is described in particular in French patent 1,405,219 (USP 3,225,533) and will not be described in detail. It is used to treat both son continuous filament as spun yarns, or, as is disclosed in United States Patent No. 4,033,102 of £ autotordus son of which at least one of the constituents has a soul in its central part. If this technique has undergone a certain industrial development for many years, it must however be recognized that the autotorsion machines marketed to date do not fully meet the wishes of the users. Indeed, these machines are very specialized, have a small number of working positions and are difficult to use for satisfactorily treating textile materials of different nature and / or for adapting ancillary devices, such as texturing means and / or drawing, making it possible to produce yarns having different properties and / or characteristics.

Or, on a trouvé, et c'est ce qui fait l'objet de la présente invention, un nouveau type de machine susceptible de produire une grande variété de fils autotordus, pouvant être adaptée facilement pour traiter des matières premières de nature très différente, tout en étant d'une conception simple, facile à entretenir et à mettre en oeuvre.However, we have found, and this is the subject of the present invention, a new type of machine capable of producing a wide variety of self-twisted yarns, which can be easily adapted to process raw materials of very different nature, while being of a design simple, easy to maintain and implement.

La machine selon l'invention pour la réalisation de fils autotordus est du type comportant, d'une manière comparable à de nombreuses machines de texturation par fausse-torsion, une pluralité de positions de travail identiques, disposées côte à côte sur un bâti support, chaque position comprenant :

  • - d'une part, des moyens d'alimentation en fils à traiter,
  • - d'autre part, séparés des moyens précités de manière à former une zone de passage pour l'opérateur, des moyens de traitement des fils disposés verticalement sur un bâti support commun et elle se caractérise par le fait que les moyens de traitement sont constitués de haut en bas par :
    • . un délivreur positif de fil délivrant deux fils en parallèle,
    • . des moyens permettant de communiquer une torsion alternée à au moins l'un des deux fils ainsi que l'autoretordage des deux fils l'un sur l'autre,
    • . des moyens de renvidage conventionnels permettant de communiquer ou non une torsion au fil produit.
The machine according to the invention for producing self-twisted yarns is of the type comprising, in a manner comparable to many false-twist texturing machines, a plurality of identical working positions, placed side by side on a support frame, each position including:
  • on the one hand, means for feeding the son to be treated,
  • - on the other hand, separated from the above-mentioned means so as to form a passage area for the operator, means for processing the wires arranged vertically on a common support frame and it is characterized in that the treatment means are constituted from top to bottom by:
    • . a positive wire deliverer delivering two wires in parallel,
    • . means making it possible to communicate an alternating twist to at least one of the two wires as well as the self-twisting of the two wires to one another,
    • . conventional winding means making it possible to communicate or not a twist to the product thread.

Avantageusement, un dispositif d'appel du fil autotordu est disposé entre les moyens de renvidage et la zone où s'effectue l'autotordage des deux fils l'une sur l'autre.Advantageously, a device for calling the self-twisted thread is disposed between the winding means and the zone where the self-twisting of the two threads is carried out on one another.

Une telle conception de machine comprenant deux corps distincts est utilisée depuis longtemps dans le domaine de la texturation par fausse torsion et est décrite notamment dans les demandes de brevets français 2 381 845 et 2 410065.Such a machine design comprising two separate bodies has been used for a long time in the field of false twist texturing and is described in particular in French patent applications 2 381 845 and 2 410065.

Cependant, il n'avait jamais été envisagé d'appliquer ces enseignements aux machines permettant la réalisation de fils autotordus. Cela peut peut-être s'expliquer par le processus même permettant d'obtenir de tels fils, processus qui implique dans un premier temps de traiter les fils élémentaires séparément en parallèle, puis, dans un deuxième temps, immédiatement après avoir communiqué à au moins l'un des fils une torsion alternée à provoquer l'enroulement (autotordage) des deux fils l'un avec l'autre. Or, un tel processus ne semble pouvoir être mis en oeuvre correctement, du moins à priori, qu'à condition de travailler horizontalement,de préférence en maintenant le fil sur une surface de guidage,ainsi que le montrent bien les seules machines d'autotordage commercialisées à ce jour, et: également l'USP 4 164 839 qui concerne plus particulièrement l'obtention d'un fil à âme dans lequel l'enveloppe fibreuse présente une torsion alternée.However, it had never been envisaged to apply these teachings to machines allowing the realization of self-twisted threads. This can perhaps be explained by the very process allowing obtaining such threads, a process which initially involves treating the elementary threads separately in parallel, then, in a second step, immediately after having communicated to at least one of the wires an alternating twist to cause the winding (self-twisting) of the two wires with each other. However, such a process seems to be able to be implemented correctly, at least a priori, only on condition of working horizontally, preferably by keeping the wire on a guide surface, as the only self-twisting machines clearly show. marketed to date, and: also USP 4 164 839 which relates more particularly to obtaining a core wire in which the fibrous envelope has an alternating twist.

Or, au contraire, cette disposition verticale des organes de traitement et ce trajet du haut vers le bas de la matière permet non seulement d'obtenir des fils autotordus réguliers, mais également d'augmenter les vitesses de production. De plus, on constate que dans le cas où l'on réalisait des fils autotordus selon la technique décrite dans l'USP 4 033 102, c'est-à-dire des fils autotordus dont au moins l'un des composants présente une âme,que la disposition verticale des manchons d'étirage et l'incorporation en biais de l'âme permettaient un meilleur centrage de ladite âme au milieu des fibres et évitaient l'utilisation de moyens annexes (conduit de soufflage) pour amener l'âme à l'intérieur de la mèche de fibres.However, on the contrary, this vertical arrangement of the processing members and this path from the top to the bottom of the material makes it possible not only to obtain regular self-twisted yarns, but also to increase production speeds. In addition, we note that in the case where self-twisted yarns were produced according to the technique described in USP 4 033 102, that is to say self-twisted yarns of which at least one of the components has a core. , that the vertical arrangement of the stretch sleeves and the biased incorporation of the core allowed better centering of said core in the middle of the fibers and avoided the use of additional means (blowing duct) to bring the core to inside the fiber wick.

Par ailleurs, une telle installation présente par rapport aux machines antérieures permettant de réaliser des fils autotordus de très nombreux avantages par le fait qu'elle peut être facilement adaptée pour traiter des matières de nature différente et/ou pour effectuer éventuellement des traitements complémentaires sur ces matières.Furthermore, such an installation presents, compared to the previous machines, making it possible to produce self-twisted yarns with very numerous advantages in that it can be easily adapted to treat materials of different nature and / or to possibly carry out additional treatments on these materials.

Ainsi, si l'alimentation en fils peut être réalisée, à partir de bobines disposées sur un cantre, elle pourrait être facilement mise en série avec d'autres matériels d'obtention de fils, par exemple à la suite d'une étireuse de fils chimiques.Thus, if the feeding of wires can be carried out, from coils arranged on a creel, it could be easily put in series with other materials for obtaining wires, for example following a wire drawing machine chemicals.

Par ailleurs, il a été noté, que l'encrassement des organes de traitement se trouvait réduit par rapport aux machines dans lesquelles la matière textile est traitée horizontalement.Furthermore, it was noted that the fouling of the processing members was reduced compared to the machines in which the textile material is treated horizontally.

Dans la suite de la description, la machine selon l'invention sera décrite en utilisant comme système d'alimentation en fils unecantre disposée au même niveau que le bâti supportant les moyens de traitement du fil, mais il est évident, comme dit précédemment, que cela n'est pas limitatif.In the following description, the machine according to the invention will be described using as a wire feed system a hanger disposed at the same level as the frame supporting the wire processing means, but it is obvious, as said above, that this is not limiting.

Dans cette forme de réalisation, le délivreur positif du fil délivrant la matière est situé à proximité de cette cantre.In this embodiment, the positive deliverer of the wire delivering the material is located near this creel.

Dans la suite de la description et afin d'éviter toutes confusions, le délivreur espacé des moyens de traitement sera désigné par l'expression "délivreur d'alimentation" et celui disposé en amont des moyens permettant de communiquer la torsion alternée par l'expression "délivreur d'autotordage".In the following description, and in order to avoid any confusion, the deliverer spaced from the processing means will be designated by the expression "supply deliverer" and that located upstream of the means making it possible to communicate the alternating twist by the expression "self-twisting provider".

Grâce à une telle disposition, il est possible d'effectuer entre le délivreur d'alimentation et le délivreur d'autotordage, des traitements complémentaires par exemple un étirage à froid du fil traité. Par ailleurs, il peut également être envisagé de disposer entre ces deux éléments un organe de traitement thermique, tel qu'un four ou un doigt d'étirage si le fil traité est un fil non ou partiellement étiré.Thanks to such an arrangement, it is possible to carry out, between the feeder and the self-twisting deliverer, additional treatments, for example cold drawing of the treated wire. Furthermore, it can also be envisaged to have between these two elements a heat treatment member, such as an oven or a drawing finger if the treated wire is an un or partially drawn wire.

De même, il peut être envisagé de disposer un ensemble de texturation par fausse torsion (four et broche) dans cette zone ou tout autre traitement similaire.Similarly, it may be envisaged to have a set of texturing by false twist (oven and spit) in this area or any other similar treatment.

Une telle machine convient particulièrement bien pour la réalisation de fils autotordus dont au moins l'un des composants présente une âme, du type de ceux décrits dans l'USP 4 033 102. Dans cette forme de réalisation, le délivreur d'autotordage est constitué par la dernière paire de cylindres d'un système d'étirage d'une mèche, ce train d'étirage étant disposé de préférence verticalement au dessus des organes de traitement, mais pouvant également avoir éventuellement une autre orientation. Dans ce cas, l'alimentation en mèches est réalisée à partir de bobines maintenues dans la partie supérieure du bâti. Cependant, on pourrait envisager d'alimenter l'installation directe- tement à partir d'un câble que l'on craquerait avant passage dans le train d'étirage.Such a machine is particularly well suited for producing self-twisted yarns of which at least one of the components has a core, of the type of those described in USP 4 033 102. In this embodiment, the self-twisting deliverer is constituted by the last pair of cylinders of a drawing system of a wick, this drawing train being preferably arranged vertically above the processing members, but possibly also having another orientation. In this case, the wicks are supplied from coils held in the upper part of the frame. However, one could consider supplying the direct installation- from a cable that you would crack before passing through the drawing train.

Les avantages et les possibilités qu'offre une telle machine seront cependant mieux compris grâce aux exemples de réalisation donnés ci-après à titre indicatif, mais non limitatif et qui sont illustrés par les schémas annexés.

Si l'on se reporte aux figures 1 et 2, la machine selon l'invention comporte une pluralité de positions de travail identiques disposées côte à côte sur un bâti support.If we refer to Figures 1 and 2, the machine according to the invention comprises a plurality of identical working positions arranged side by side on a support frame.

Conformément à l'invention, les délivreurs d'alimentation 1 en fil 2 sont séparés des moyens de traitement proprement dit du fil de manière à former une zone de passage 3 pour l'opérateur.According to the invention, the wire feeders 1 are separated from the wire processing means so as to form a passage area 3 for the operator.

Dans ce mode de réalisation, le fil 2 provient de bobines stockées sur une cantre conventionnelle 5 disposée au même niveau et espacée des moyens de traitement. Eventuellement, la cantre 5 pourrait être située sur une plate- forme de manière à libérer l'espace au sol.In this embodiment, the wire 2 comes from coils stored on a conventional creel 5 disposed at the same level and spaced from the processing means. Optionally, the creel 5 could be located on a platform so as to free up the space on the ground.

Les moyens de traitement du fil sont regroupés sur un bâti commun 6, représenté en pointillés sur la figure 1. Ces moyens de traitement sont constitués de haut en bas par un délivreur d'autotordage 7 permettant de délivrer deux fils 2 en parallèle.The wire processing means are grouped together on a common frame 6, shown in dotted lines in FIG. 1. These processing means are constituted from top to bottom by a self-twisting deliverer 7 making it possible to deliver two wires 2 in parallel.

Par ailleurs, des moyens conventionnels 8 sont disposés en dessous de ce dêlivreur 7 et communiquent une torsion alternée aux deux fils 2 traités. Bien entendu, on pourrait se contenter de communiquer une telle torsion alternée à un seul fil.Furthermore, conventional means 8 are arranged below this release 7 and communicate an alternating twist to the two treated wires 2. Of course, one could be content to communicate such an alternating twist to a single wire.

Enfin, un second délivreur 9 permet l'appel du fil autoretordu produit qui est alors renvidé de manière conventionnelle en 10.Finally, a second deliverer 9 allows the self-twisted yarn produced to be called up, which is then returned conventionally at 10.

Comme délivreur d'autotordage 7, on utilisera par exemple un délivreur formé par un arbre continu 11 s'étendant sur toute la largeur de la machine et sur lequel prennent appui des galets 12, 13 permettant de délivrer les fils 2 individuellement.As a self-twisting deliverer 7, a deliverer formed by a continuous shaft 11 extending over the entire width of the machine will be used, for example, on which rollers 12, 13 support the wires 2 individually.

Par ailleurs, les moyens 8 permettant de communiquer une torsion alternée au fil sont constitués, dans le cas présent, par un ensemble comportant un organe de fausse torsion 14, formé par exemple de courroies croisées traitant simultanément les deux fils 2. La torsion alternée est obtenue en faisant varier la longueur de remontée de torsion entre la broche 14 et le délivreur d'autotordage 7 par exemple au moyen d'un délivreur intermittent conventionnel 15. Les deux fils élémentaires 2 ayant reçus une torsion alternée sont assemblés par simple autordage en aval de la broche 14, leur jonction étant obtenue au moyen d'un guide 16.Furthermore, the means 8 making it possible to communicate an alternating twist to the wire consist, in the present case, of an assembly comprising a false twist member 14, formed for example of crossed belts simultaneously treating the two wires 2. The alternating twist is obtained by varying the length of the twist rise between the spindle 14 and the self-twisting deliverer 7 for example by means of a conventional intermittent deliverer 15. The two elementary wires 2 having received an alternating twist are assembled by simple downstream twisting of spindle 14, their junction being obtained by means of a guide 16.

Le délivreur 9 d'appel du fil formé peut également être constitué par un arbre continu 17, sur lequel prennent appui des manchons individuels 18 conventionnels.The caller 9 for the formed wire can also consist of a continuous shaft 17, on which support individual conventional sleeves 18.

Le renvidage 10 est réalisé de manière conventionnelle par exemple par entraînement tangentiel. Il est évident que l'on pourrait également réaliser un renvidage au moyen d'une broche à anneau et curseur, si par exemple on désire tordre le fil formé.The winding 10 is carried out in a conventional manner, for example by tangential drive. It is obvious that one could also carry out a winding by means of a pin with ring and cursor, if for example one wishes to twist the wire formed.

Une telle installation permet de traiter facilement tout type de fil, qu'il soit à base de filaments continus ou de filés de fibres.Such an installation makes it possible to easily treat any type of yarn, whether it is based on continuous filaments or yarns of fibers.

Eventuellement, un étirage à froid peut être effectué en réglant les vitesses respectives du délivreur d'alimentation 1 et du délivreur d'autotordage 7.Optionally, cold drawing can be performed by adjusting the respective speeds of the feeder 1 and the self-twist 7.

Il faut également noter qu'une telle machine permet de regrouper dos à dos deux positions de travail sur un même bâti.It should also be noted that such a machine allows two working positions to be grouped back to back on the same frame.

Si dans l'exemple de réalisation illustré par les figures 1 et 2, les deux fils 2 qui doivent être autotordus sont amenés en parallèle mais subissent cependant un léger changement de direction à la sortie du délivreur d'autotordage 11, par exemple au moyen de guides 30, 31 permettant de diminuer leur écartement, on pourrait bien entendu envisager de maintenir constant l'écartement entre ces fils tout au long du traitement ainsi que cela est représenté en traits mixtes sur la figure 2. Dans ce cas, les guides 30, 31 pourraient éventuellement être supprimés. De plus, ainsi que cela est représenté également en traits mixte à la figure 1, le délivreur 1 pourrait être disposé directement au dessus et dans le même plan vertical que le délivreur d'autotordage 7 et que les moyens 8 permettant de communiquer la torsion alternée aux fils.If in the embodiment illustrated in FIGS. 1 and 2, the two wires 2 which must be self-twisted are brought in parallel but nevertheless undergo a slight change of direction at the exit of the self-twisting deliverer 11, for example by means of guides 30, 31 making it possible to reduce their spacing, one could of course envisage keeping the spacing between these wires constant throughout the treatment, as shown in dashed lines in FIG. 2. In this case, the guides 30, 31 could possibly be deleted. In addition, as also shown in phantom in Figure 1, the deliverer 1 could be arranged directly above and in the same vertical plane as the self-twisting deliverer 7 and that the means 8 for communicating the alternating torsion to the sons.

Les figures 3, 4, 5, 6 et 7 illustrent les adaptations qui peuvent être réalisées de manière simple sur un tel type de machine.Figures 3, 4, 5, 6 and 7 illustrate the adaptations which can be carried out in a simple manner on such a type of machine.

Ainsi, les figures 3 et 4 montrent l'adaptation de cette machine pour la réalisation de fils autotordus à âme. Dans ce mode de réalisation, on dispose dans la partie supérieure du bâti 6 une alimentation 19 en mèches de fibres 20. Par ailleurs, le délivreur d'autotordage 7 est constitué par la dernière paire de cylindres d'un système d'étirage conventionnel tel que par exemple un système à double manchons 21.Thus, Figures 3 and 4 show the adaptation of this machine for the production of self-twisted core wires. In this embodiment, there is at the upper part of the frame 6 a supply 19 of wicks of fibers 20. Furthermore, the self-twisting deliverer 7 is constituted by the last pair of cylinders of a conventional stretching system such as for example a double sleeve system 21.

Dans ce mode de réalisation, les fils d'âme sont constitués par les fils 2 provenant de la cantre 5,ces fils étant incorporés à la mèche 20 immédiatement en amont du . délivreur d'étirage 7, un condenseur 22 pouvant être prévu-dans cette zone pour faciliter l'introduction de l'âme dans la mèche.In this embodiment, the core wires consist of the wires 2 coming from the creel 5, these wires being incorporated into the wick 20 immediately upstream of the. stretching deliverer 7, a condenser 22 can be provided in this zone to facilitate the introduction of the core into the wick.

Comme dans l'exemple de réalisation illustré par les figures 1 et 2, des guides 30, 31 peuvent être prévus à la sortie du délivreur d'autotordage 7 pour diminuer l'écartement entre les fils dans la zone où ils subissent l'opération permettant de leur communiquer une torsion alternée. Comme précédemment, il pourrait être envisagé de maintenir la distance entre les fils constante sur toute la longueur du traitement.As in the embodiment illustrated by Figures 1 and 2, guides 30, 31 may be provided at the outlet of the self-twisting deliverer 7 to reduce the spacing between the wires in the area where they undergo the operation allowing them to communicate an alternating twist. As before, it could be envisaged to keep the distance between the wires constant over the entire length of the treatment.

La figure 5 illustre une variante dans laquelle un organe de traitement thermique 23, tel qu'un four, est disposé dans la partie supérieure de la machine. Ce four 23,qui peut être un four ouvert ou un four fermé, est de préférence disposé horizontalement ou légèrement en biais dans la partie supérieure de la machine. Eventuellement, un délivreur complémentaire 24 représenté en pointillés sur cette figure 5, est prévu à la sortie du four 23 et permet d'effectuer un étirage à chaud, en coopération avec le délivreur d'alimentation 1.FIG. 5 illustrates a variant in which a heat treatment member 23, such as an oven, is arranged in the upper part of the machine. This oven 23, which can be an open oven or a closed oven, is preferably arranged horizontally or slightly at an angle in the upper part of the machine. Optionally, a complementary deliverer 24 shown in dotted lines in this FIG. 5, is provided at the outlet of the oven 23 and makes it possible to carry out a hot drawing, in cooperation with the feeder 1.

Ce type de matériel peut également être équipé d'un système d'alimentation en mèches 20. Auquel cas, l'inclinaison du four 23 est telle que le fil 2 soit amené en biais en amont de la dernière paire de rouleaux du train d'étirage formant le délivreur d'autotordage 7.This type of material can also be equipped with a wick feed system 20. In which case, the inclination of the oven 23 is such that the wire 2 is brought obliquely upstream of the last pair of rollers of the train. stretch forming the self-twisting deliverer 7.

La figure 6 illustre une variante dans laquelle on effectue une opération de texturation par fausse torsion entre le délivreur d'alimentation 1 et le délivreur d'autotordage 7. Bien entendu, cette opération de texturation peut être combinée à un étirage simultané du fil 2. Une plaque de refroidissement 25 peut être prévue entre la broche 26 et le four 23.FIG. 6 illustrates a variant in which a texturing operation is carried out by false twist between the feeder 1 and the self-twisting unit 7. Of course, this texturing operation can be combined with a simultaneous drawing of the wire 2. A cooling plate 25 can be provided between the spindle 26 and the oven 23.

Dans tous les exemples qui précèdent, les organes de traitement sont montés de manière symétrique sur un bâti commun.In all of the above examples, the processing members are mounted symmetrically on a common frame.

La figure 7 illustre une variante d'une machine dans laquelle le délivreur d'alimentation 1, qui conformément à l'invention est séparé des organes de traitement, est disposé à un niveau inférieur de manière à pouvoir adapter entre ce délivreur et les organes de traitement, une installation de texturation, par exemple par fausse torsion, comportant également un four 23, un parcours de refroidissement 25 et une broche 26. Dans ce mode de réalisation, la zone de passage 3 pour l'opérateur est située entre la zone de texturation et la zone de traitement permettant d'obtenir le fil autotordu.FIG. 7 illustrates a variant of a machine in which the feeder 1, which in accordance with the invention is separated from the treatment members, is arranged at a lower level so as to be able to adapt between this deliverer and the control members processing, a texturing installation, for example by false twisting, also comprising an oven 23, a cooling path 25 and a spindle 26. In this embodiment, the passage zone 3 for the operator is located between the texturing zone and the treatment zone allowing the self-twisted yarn to be obtained .

Eventuellement, comme précédemment, un système d'amenée d'une mèche 20 de fibres peut être prévu dans la partie supérieure de la machine.Optionally, as before, a system for feeding a wick of fibers can be provided in the upper part of the machine.

Les exemples qui précèdent montrent bien les avantages apportée par l'invention et la grande souplesse d'un tel matériel. Bien entendu, l'invention n'est pas limitée à ces modes de réalisation, mais elle en couvre toutes les variantes réalisées dans le même esprit.The above examples clearly show the advantages provided by the invention and the great flexibility of such equipment. Of course, the invention is not limited to these embodiments, but it covers all the variants produced in the same spirit.

Par ailleurs, il est évident,-bien que cela n'ait pas été décrit, que la machine comporte des moyens détecteurs de de casse et d'arrêt pour chaque position, et peut être équipée de tout moyen conventionnel permettant de traiter correctement le fil, par exemple des régulateurs de tension, des systèmes d'aspiration permettant d'effectuer correctement les lancements et/ou d'éliminer les duvets qui pourraient s'échapper lors du traitement.Furthermore, it is obvious, although it has not been described, that the machine includes means for detecting breakage and stopping for each position, and can be equipped with any conventional means allowing the wire to be treated correctly. , for example voltage regulators, suction systems allowing correct launches and / or eliminating the down that might escape during the treatment.
