Titre de l'invention : DISPOSITIF DE FABRICATION D'UN ÉLÉMENT ALLONGÉ TEXTILE ET NON CONSOLIDÉ Title of the invention: DEVICE FOR MANUFACTURING AN ELONGATED TEXTILE AND NON-CONSOLIDATED ELEMENT
[0001] La présente invention concerne le domaine technique des dispositifs de fabrication d'un élément allongé textile et non consolidé ainsi que le procédé de fabrication associé et l'élément allongé textile et non consolidé obtenu. The present invention relates to the technical field of devices for manufacturing an elongated textile and unconsolidated element as well as the associated manufacturing process and the elongated textile and unconsolidated element obtained.
[0002] Dans le domaine ci-dessus, il est connu des méthodes de tressage pour former notamment des tubes allongés. Ces tubes pour être utilisables sont ensuite consolidés pour former des tubes composites. In the above field, it is known braiding methods to form including elongated tubes. These tubes to be usable are then consolidated to form composite tubes.
[0003] Cependant de telles méthodes sont coûteuses, ne permettent pas de fabriquer en grande quantité et sont contraignantes quant à la forme tubulaire obtenue. [0003] However, such methods are expensive, do not allow large quantities to be manufactured and are restrictive as to the tubular shape obtained.
[0004] Il existe également des machines de fabrication de tubes composites comprenant différentes couches de ruban les unes disposées sur les autres, une couche comprenant une résine qui se mélange et interagie avec les rubans des couches supérieures. Ces tubes présentent une matrice rigide et ne sont pas facilement transformables. [0004] There are also machines for manufacturing composite tubes comprising different layers of tape placed one on top of the other, one layer comprising a resin which mixes and interacts with the tapes of the upper layers. These tubes have a rigid matrix and are not easily transformed.
[0005] La présente invention vise à pallier ces inconvénients, et à fabriquer un élément allongé textile et non consolidé pouvant comprendre de grandes dimensions et étant transformable facilement. The present invention aims to overcome these drawbacks, and to manufacture an elongated textile and unconsolidated element that can include large dimensions and can be easily transformed.
[0006] A cet effet, l'invention concerne un dispositif de fabrication d'un élément allongé textile et non consolidé comprenant : To this end, the invention relates to a device for manufacturing an elongated textile and unconsolidated element comprising:
- un bâti comprenant un guide principal longitudinal selon une direction X, ledit guide principal étant fixe sur le bâti et - a frame comprising a main longitudinal guide in an X direction, said main guide being fixed on the frame and
- au moins deux modules disposés en série autour du guide principal selon la direction X, chaque module comprenant : - at least two modules arranged in series around the main guide in the direction X, each module comprising:
- une couronne d'alimentation entourant une section du guide principal,- a feed ring surrounding a section of the main guide,
- des moyens d'alimentation disposés sur la couronne aptes à alimenter au moins un ruban vers le guide principal selon un angle compris entre -90° et 90° avec la direction X et selon une vitesse d'avancée VI, chaque ruban étant apte à s'enrouler au moins autour du guide principal ou sur la couche de ruban supérieure, et - feed means arranged on the crown capable of feeding at least one ribbon to the main guide at an angle between -90° and 90° with the direction X and according to an advance speed VI, each ribbon being able to wrap at least around the main guide or over the top ribbon layer, and
- des moyens d'entraînement de la couronne aptes à faire tourner la couronne autour du guide principal selon une vitesse de rotation V2. [0007] La mise en œuvre de moyens d'alimentation de ruban autour d'un guide principal permet de déployer facilement les rubans dans une même direction. Chaque module peut ainsi délivrer au moins un ruban selon une direction donnée et l'élément allongé comprend ainsi plusieurs couches de ruban, chaque couche comprenant au moins un ruban disposé selon un angle donné. La couche supérieure est définie comme la dernière couche posée. - crown drive means capable of rotating the crown around the main guide according to a speed of rotation V2. [0007] The implementation of ribbon supply means around a main guide makes it possible to easily deploy the ribbons in the same direction. Each module can thus deliver at least one ribbon in a given direction and the elongated element thus comprises several layers of ribbon, each layer comprising at least one ribbon arranged at a given angle. The top layer is defined as the last layer laid.
[0008] Le dispositif selon l'invention permet de superposer autant de couches de ruban voulues que de nombre de modules mis en œuvre. La vitesse d'avancée VI correspond à la vitesse d'avancée de l'élément textile par rapport au guide principal du dispositif. La vitesse VI est ainsi sensiblement la même pour chaque module du dispositif. [0008] The device according to the invention makes it possible to superimpose as many layers of ribbon as desired as there are modules implemented. The forward speed VI corresponds to the forward speed of the textile element relative to the main guide of the device. The speed VI is thus substantially the same for each module of the device.
[0009] Un tel élément allongé obtenu par le dispositif selon l'invention présente de nombreux avantages. L'élément allongé est ainsi non consolidé et donc peut être facilement cintré à froid afin de lui donner une forme particulière non rectiligne. L'élément allongé peut être consolidé ensuite, par exemple, en le transformant dans un outillage compatible.Such an elongated element obtained by the device according to the invention has many advantages. The elongated element is thus unconsolidated and therefore can be easily cold bent in order to give it a particular non-rectilinear shape. The elongated element can then be consolidated, for example, by transforming it into a compatible tool.
[0010] Les rubans sont déposés vers le guide principal avec un angle strictement supérieur à -90° par rapport à la direction X d'avancement de l'élément textile et strictement inférieur à 90° par rapport à la direction X d'avancement de l'élément textile. [0010] The ribbons are deposited towards the main guide with an angle strictly greater than −90° with respect to the direction X of advancement of the textile element and strictly less than 90° with respect to the direction X of advancement of the textile element.
[0011] Au sens de l'invention, un ruban est dit textile et comprend donc des fibres, par exemple des fibres de carbone unidirectionnelle, il s'agit alors de fibres sèches. Un ruban compatible avec l'invention est apte à s'enrouler autour du guide principal et comprend une structure suffisamment rigide pour rester enroulé autour du guide principal. [0011] Within the meaning of the invention, a ribbon is said to be textile and therefore comprises fibers, for example unidirectional carbon fibers, these are then dry fibers. A ribbon compatible with the invention is capable of being rolled up around the main guide and comprises a sufficiently rigid structure to remain rolled up around the main guide.
[0012] Un ruban compatible avec l'invention peut également être constitué de plastique, céramique, métal, papier ou mélanges de ces matières sans être exhaustif. Un ruban compatible avec l'invention est ainsi défini comme toute matière apte à se former autour d'un guide principal et résistant aux efforts inhérents au dispositif selon l'invention. [0012] A ribbon compatible with the invention can also be made of plastic, ceramic, metal, paper or mixtures of these materials, without being exhaustive. A ribbon compatible with the invention is thus defined as any material able to form around a main guide and resistant to the forces inherent in the device according to the invention.
[0013] Selon une forme de réalisation particulière, un ruban peut comprendre en outre une matrice destinée à se solidifier rapidement et un élément allongé textile consolidé peut être obtenu avec le dispositif de l'invention. [0013] According to a particular embodiment, a tape may further comprise a matrix intended to solidify rapidly and a consolidated textile elongate element may be obtained with the device of the invention.
[0014] Selon une forme de réalisation de l'invention, un ruban formé de fibres unidirectionnelles imprégné d'une matrice thermoplastique est doté d'une rigidité de flexion suffisante pour garder une forme enroulée sans le besoin de garder un support. [0014] According to one embodiment of the invention, a ribbon formed from unidirectional fibers impregnated with a thermoplastic matrix has sufficient bending rigidity to keep a rolled shape without the need to keep a support.
[0015] De tels rubans permettent de fabriquer un élément textile comprenant notamment une première couche de ruban orienté avec un angle de 0° par rapport au guide principal du dispositif, cette première couche de ruban étant apte à glisser sur le dit guide principal fixe sur le bâti et à entraîner les couches supérieures qui reposent sur la première.[0015] Such ribbons make it possible to manufacture a textile element comprising in particular a first layer of ribbon oriented with an angle of 0° relative to the main guide of the device, this first layer of tape being able to slide on said main guide fixed on the frame and to drive the upper layers which rest on the first.
[0016] Un des avantages de l'utilisation de tels rubans dans le dispositif permet une alimentation en continue des rubans et donc assure une production en continue. De plus, l'élément allongé textile obtenu est suffisamment solide et le guide principal du dispositif est fixe sur le bâti et donc ne fait pas partie de l'élément allongé textile obtenu. Au contraire de certains dispositifs existants, il n'est ainsi pas nécessaire de mettre en œuvre une étape de chauffe du matériau destinée à le solidifier pour obtenir un élément final utilisable. [0016] One of the advantages of using such ribbons in the device allows continuous supply of the ribbons and therefore ensures continuous production. In addition, the elongated textile element obtained is sufficiently strong and the main guide of the device is fixed to the frame and therefore does not form part of the elongated textile element obtained. Unlike certain existing devices, it is thus not necessary to implement a step of heating the material intended to solidify it in order to obtain a usable final element.
[0017] L'élément allongé textile et non consolidé obtenu peut être utilisé directement, il ne s'agit pas d'un élément intermédiaire. Cependant selon certaines utilisations voulues, des étapes supplémentaires peuvent être appliquées à l'élément allongé obtenu pour le transformer et/ou le consolider. [0017] The elongated textile and unconsolidated element obtained can be used directly, it is not an intermediate element. However, according to certain desired uses, additional steps can be applied to the elongated element obtained to transform and/or consolidate it.
[0018] Selon une caractéristique de l'invention, chaque module comprend des moyens d'alimentation indépendants. Ainsi, chaque module peut distribuer des rubans de nature différente. La nature et les dimensions des rubans peuvent être différents d'une couche à l'autre. [0018] According to a characteristic of the invention, each module comprises independent supply means. Thus, each module can dispense ribbons of a different nature. The nature and dimensions of the ribbons may be different from one layer to another.
[0019] Selon une autre caractéristique de l'invention, le guide longitudinal principal comprend une section sensiblement circulaire ou polygonale ou encore de forme libre. L'élément allongé obtenu peut ainsi avoir la forme d'un tube ou peut être de forme plus complexe selon l'utilisation. [0019] According to another characteristic of the invention, the main longitudinal guide comprises a section that is substantially circular or polygonal or else of free form. The elongated element obtained may thus have the shape of a tube or may have a more complex shape depending on the use.
[0020] Selon encore une autre caractéristique de l'invention, les moyens d'alimentation comprennent au moins un distributeur de ruban disposé autour de la couronne d'alimentation. La mise en œuvre de distributeur de ruban permet un stockage et une distribution facilités des rubans vers le guide principal, le ou les distributeurs tournant autour du guide principal selon la vitesse de rotation de la couronne d'alimentation. [0020] According to yet another feature of the invention, the supply means comprise at least one tape dispenser arranged around the supply crown. The implementation of a tape dispenser allows easy storage and distribution of the tapes towards the main guide, the dispenser(s) rotating around the main guide according to the speed of rotation of the feed ring.
[0021] Selon une forme de réalisation de l'invention, les distributeurs de ruban comprennent des moyens de pivotement sur la couronne d'alimentation. La mise en œuvre de moyens de pivotement permet d'orienter la distribution des rubans vers le guide principal et ainsi de choisir un angle entre -90° et 90° entre le ruban et le guide principal. Tous les rubans d'un même module ont sensiblement le même angle avec le guide principal. [0022] Selon une autre forme de réalisation de l'invention, les distributeurs de ruban comprennent au moins une guillotine apte à couper au moins un ruban en sortie d'un distributeur et un élément motorisé apte à amener le ruban vers le guide principal. [0021] According to one embodiment of the invention, the tape dispensers include means for pivoting on the supply crown. The implementation of pivoting means makes it possible to orient the distribution of the ribbons towards the main guide and thus to choose an angle between −90° and 90° between the ribbon and the main guide. All the ribbons of the same module have substantially the same angle with the main guide. According to another embodiment of the invention, the tape dispensers comprise at least one guillotine capable of cutting at least one tape at the output of a dispenser and a motorized element capable of bringing the tape towards the main guide.
[0023] Selon une autre forme de réalisation de l'invention, les distributeurs de ruban comprennent des moyens de soudure, par exemple des moyens de soudure par ultrasons, aptes à souder un ruban sur une couche présente ou couche supérieure. D'autres moyens de soudure compatibles avec la nature des rubans utilisés sont possibles dans le cadre de l'invention. Lorsque le diamètre, ou la section s'il ne s'agit pas d'un tube, de l'élément allongé varie, il est intéressant d'ajouter ou d'enlever un ou plusieurs rubans, ce qui est possible dans le cadre de l'invention grâce à la mise en œuvre de guillotine et/ou de moyens de soudure. According to another embodiment of the invention, the tape dispensers comprise welding means, for example ultrasonic welding means, capable of welding a tape to a present layer or upper layer. Other welding means compatible with the nature of the strips used are possible within the scope of the invention. When the diameter, or the section if it is not a tube, of the elongated element varies, it is advantageous to add or remove one or more ribbons, which is possible within the framework of the invention thanks to the implementation of a guillotine and/or welding means.
[0024] Selon une forme de réalisation de l'invention, le dispositif comprend en outre dispositif d'aide au tirage apte à guider les rubans du ou des modules. [0024] According to one embodiment of the invention, the device further comprises a drawing aid device capable of guiding the strips of the module or modules.
[0025] L'utilisation d'un dispositif d'aide au tirage permet de faciliter le glissement des différentes couches de ruban le long du guide principal. Un exemple de réalisation de dispositif d'aide au tirage peut être un système d'au moins un rouleau disposé en aval du dernier module selon la direction X. Ce ou ces rouleaux exercent une pression suffisante pour entraîner le glissement des couches de ruban sur le guide principal. Selon la nature des rubans, ce dispositif d'aide peut être retiré au cours de la fabrication de l'élément textile qui par sa rigidité peut avancer seul sur le guide principal. Selon d'autres formes de réalisation, la nature des rubans ne nécessite pas d'aide au tirage. [0025] The use of a drawing aid device makes it easier to slide the different layers of tape along the main guide. An embodiment example of a pulling aid device may be a system of at least one roller arranged downstream of the last module in the direction X. This or these rollers exert sufficient pressure to cause the layers of tape to slide on the main guide. Depending on the nature of the ribbons, this aid device can be removed during the manufacture of the textile element which, due to its rigidity, can advance alone on the main guide. According to other embodiments, the nature of the ribbons does not require a drawing aid.
[0026] Selon une variante de réalisation de l'invention, le dispositif comprend en outre un guide secondaire longitudinal de diamètre ou de section supérieur au diamètre ou à la section s'il ne s'agit pas d'un tube, du guide principal et apte à translater sur le guide principal. Lorsque le dispositif est en fonctionnement, la mise en œuvre d'un guide secondaire de diamètre ou de section supérieur permet d'augmenter le diamètre, ou la section s'il ne s'agit pas d'un tube, de l'élément allongé, les rubans étant déposés sur le guide secondaire. [0026] According to a variant embodiment of the invention, the device further comprises a secondary longitudinal guide of diameter or section greater than the diameter or the section if it is not a tube, of the main guide and able to translate on the main guide. When the device is in operation, the implementation of a secondary guide of greater diameter or section makes it possible to increase the diameter, or the section if it is not a tube, of the elongated element , the ribbons being deposited on the secondary guide.
[0027] Le guide principal du dispositif selon l'invention est fixe sur le bâti et donc ne fait pas partie de l'élément allongé textile obtenu. Ainsi, au contraire des systèmes existants, le dispositif de fabrication ne comprend pas de mandrin, il est alors possible de faire varier le diamètre de l'élément textile obtenu de manière simple. De telles méthodes n'existent pas pour les dispositifs avec mandrin et sont expliquées ci-après. [0028] L'invention concerne également un procédé de fabrication d'un élément allongé textile et non consolidé comprenant les étapes suivantes : The main guide of the device according to the invention is fixed to the frame and therefore does not form part of the elongated textile element obtained. Thus, unlike existing systems, the manufacturing device does not include a mandrel, it is then possible to vary the diameter of the textile element obtained in a simple manner. Such methods do not exist for chuck devices and are explained below. The invention also relates to a method of manufacturing an elongated textile and unconsolidated element comprising the following steps:
- Mise en œuvre des moyens d'alimentation sur chacun des modules du dispositif selon l'invention, lesdits moyens d'alimentation comprenant des rubans choisis, - Implementation of the supply means on each of the modules of the device according to the invention, said supply means comprising selected ribbons,
- Paramétrage de la vitesse d'avancée VI et de la vitesse de rotation V2 de chacun des modules et mise en route de chaque module, - Parameterization of the advance speed VI and the rotation speed V2 of each of the modules and start-up of each module,
- Découpe de l'élément allongé et/ou épuisement des rubans, et - Cutting of the elongated element and/or exhaustion of the ribbons, and
- Récupération de l'élément allongé obtenu. - Recovery of the elongated element obtained.
[0029] La vitesse d'avancée VI correspond à la vitesse d'avancée de l'élément textile sur le guide principal. La vitesse d'avancée VI est donc sensiblement la même pour chacun des modules. La vitesse d'avancée VI et la vitesse de rotation V2 de chaque module sont liées, d'une part, à l'angle défini entre le ou les rubans alimentés par chacun des modules et leur vitesse d'alimentation. The forward speed VI corresponds to the forward speed of the textile element on the main guide. The forward speed VI is therefore substantially the same for each of the modules. The speed of advance VI and the speed of rotation V2 of each module are linked, on the one hand, to the angle defined between the strip or strips fed by each of the modules and their feed speed.
[0030] De tels moyens d'alimentation associés à la nature des rubans compatibles tels que décrits plus haut permet d'alimenter en continu et le dispositif et donc de mettre en œuvre un procédé en continue de fabrication d'élément allongé textile et non consolidé. Lesdits éléments textiles obtenus sont utilisables directement en sortie du dispositif. Il est à noter qu'un tel procédé de fabrication ne nécessite pas d'étape de chauffe des rubans ou de l'élément textile obtenu pour le solidifier et l'utiliser directement. [0030] Such supply means associated with the nature of the compatible ribbons as described above makes it possible to continuously supply the device and therefore to implement a continuous process for manufacturing an elongated textile and unconsolidated element. . Said textile elements obtained can be used directly at the outlet of the device. It should be noted that such a manufacturing process does not require a step of heating the ribbons or the textile element obtained in order to solidify it and use it directly.
[0031] Selon une forme de réalisation de l'invention, le procédé comprend en outre une étape de stockage de l'élément allongé enroulé autour d'une bobine de stockage. Le procédé selon l'invention permet de fabriquer jusqu'à épuisement des moyens d'alimentation en ruban un élément allongé de taille importante pouvant aller, par exemple, jusqu'au kilomètre. Stocker en bobine l'élément allongé en sortie du dispositif facilite la manutention. According to one embodiment of the invention, the method further comprises a step of storing the elongated element wound around a storage reel. The method according to the invention makes it possible to manufacture, until the tape supply means are exhausted, an elongated element of large size which can go, for example, up to one kilometer. Storing the elongated element on the reel at the outlet of the device facilitates handling.
[0032] Selon une variante de réalisation de l'invention, le procédé comprend en outre l'étape d'aide au tirage des rubans avec la mise en œuvre du dispositif d'aide au tirage. Le dispositif d'aide au tirage est placé en aval du dernier module délivrant la dernière couche de l'élément textile. Un opérateur peut, par exemple, guider chacune des couches de ruban vers le dispositif d'aide au tirage qui aidera ensuite à faire glisser les différentes couches sur le guide principal. According to a variant embodiment of the invention, the method further comprises the step of aiding the drawing of the ribbons with the implementation of the drawing aid device. The drawing aid device is placed downstream of the last module delivering the last layer of the textile element. An operator can, for example, guide each of the layers of tape towards the pulling aid device which will then help to slide the different layers on the main guide.
[0033] Selon une forme de réalisation de l'invention, la bobine de stockage est un dispositif d'aide au tirage des rubans des moyens d'alimentation des modules du dispositif de fabrication. [0034] Selon une forme de réalisation de l'invention, le procédé comprend en outre l'étape supplémentaire de disposition d'un guide secondaire longitudinal au niveau du premier module et translation dudit guide secondaire selon la direction X. Le guide secondaire permet d'agrandir le diamètre ou la section s'il ne s'agit pas d'un tube, de l'élément allongé en cours de fabrication ou de diminuer le diamètre ou la section de l'élément si un premier guide secondaire a déjà été mis en œuvre. According to one embodiment of the invention, the storage reel is a device for assisting the drawing of the ribbons from the supply means of the modules of the manufacturing device. According to one embodiment of the invention, the method further comprises the additional step of arranging a longitudinal secondary guide at the level of the first module and translation of said secondary guide in the direction X. The secondary guide makes it possible to 'enlarge the diameter or the section if it is not a tube, of the elongated element being manufactured or reduce the diameter or the section of the element if a first secondary guide has already been placed implemented.
[0035] Selon une forme de réalisation de l'invention, le procédé comprend en outre une étape de cintrage à froid de l'élément allongé obtenu selon un angle voulu. Un avantage du dispositif de fabrication est la possibilité de cintrer à froid l'élément allongé. According to one embodiment of the invention, the method further comprises a step of cold bending the elongated element obtained at a desired angle. An advantage of the manufacturing device is the possibility of cold bending the elongated element.
[0036] Selon une forme de réalisation de l'invention, le procédé comprend en outre une étape de variation de diamètre, ou de la section s'il ne s'agit pas d'un tube, de l'élément allongé. D'autres moyens que la mise en œuvre du guide secondaire peuvent être mis en œuvre pour agrandir ou diminuer le diamètre, ou la section s'il ne s'agit pas d'un tube, de l'élément allongé. Par exemple, il est possible de prévoir une certaine orientation des rubans de chaque couche pour anticiper une étape supplémentaire finale permettant d'obtenir une variation du diamètre de l'élément allongé pouvant aller jusqu'à 50%. According to one embodiment of the invention, the method further comprises a step of varying the diameter, or the section if it is not a tube, of the elongated element. Means other than the implementation of the secondary guide can be implemented to enlarge or reduce the diameter, or the section if it is not a tube, of the elongated element. For example, it is possible to provide a certain orientation of the ribbons of each layer to anticipate a final additional step making it possible to obtain a variation in the diameter of the elongated element which may be up to 50%.
[0037] L'invention concerne également un élément allongé textile et non consolidé obtenu à partir du dispositif de fabrication selon l'invention. The invention also relates to an elongated textile and unconsolidated element obtained from the manufacturing device according to the invention.

La figure 3 illustre un élément allongé 11 obtenu au moyen du dispositif 1 selon l'invention. Ce sont les couches successives de ruban 10 disposés avec des angles différents qui permettent à l'élément allongé 11 obtenu de garder sa forme. La figure 4 illustre une coupe de cet élément allongé 11 où les couches successives sont visibles. A ribbon 10 compatible with the invention is, on the one hand, sufficiently flexible to wrap around the main guide 3.

[0059] Le dispositif illustré aux figures 1 et 2 comprend deux modules 4. Les moyens d'alimentation 6 du premier module 4 comprennent deux distributeurs 20 de ruban 10 et les moyens d'alimentation 6 du second module 4 comprennent un seul distributeur 20 de ruban 10. Les moyens d'alimentations 6 des différents modules 4 sont en effet indépendants les uns des autres. Ainsi chaque module 4 peut délivrer des rubans 10 de nature différente et un nombre choisi de ruban 10 par couche. The device illustrated in Figures 1 and 2 comprises two modules 4. The supply means 6 of the first module 4 comprise two distributors 20 of ribbon 10 and the supply means 6 of the second module 4 comprise a single distributor 20 of ribbon 10.

[0060] La figure 6 illustre un module 4 comprenant six distributeurs 20 de ruban 10. Les distributeurs 20 de ruban 10 sont disposés autour de la couronne d'alimentation 5. Selon les formes de réalisation illustrées, un distributeur 20 de ruban 10 comprend une bobine 21 fixée sur une face de la couronne 5 avec des moyens de pivotement 22. Selon cette forme de réalisation illustrée mais non limitative, les moyens de pivotement 22 comprennent une partie fixe 23 et une partie pivotante 24 dirigée vers la bobine 21. La bobine 21 est libre de pivoter dans la partie pivotante 24 et la partie pivotante est libre de pivoter par rapport à la partie fixe 23. Ainsi, la bobine 21 peut être disposée selon une configuration voulue et les moyens de pivotement 22 peuvent être bloqués selon la disposition voulue du distributeur 20.

The coil 21 is free to pivot in the pivoting part 24 and the pivoting part is free to pivot relative to the fixed part 23. Thus, the coil 21 can be arranged according to a desired configuration and the pivoting means 22 can be blocked according to the desired layout of the distributor 20.
[0061] La figure 7 illustre un exemple de réalisation particulier de l'invention dans lequel un distributeur 20 de ruban 10 comprend également, une guillotine 25 apte à couper le ruban 10 en sortie du distributeur 20, un moteur M apte à alimenter le ruban après découpe et des moyens de soudure 26 par ultrasons aptes à souder un ruban 10 au niveau d'une couche de rubans 10 présente ou couche supérieure. L'illustration du moteur M, de la guillotine 25 et des moyens de soudure 26 est schématique sur la figure 7 et d'autres formes de réalisation sont possibles et notamment avec des moyens d'agir sur un ruban 10 hors du distributeur 20. [0061] Figure 7 illustrates a particular embodiment of the invention in which a dispenser 20 of tape 10 also comprises a guillotine 25 capable of cutting the tape 10 at the outlet of the dispenser 20, a motor M capable of supplying the tape after cutting and ultrasonic welding means 26 able to weld a strip 10 at a layer of strips 10 present or upper layer. The illustration of the motor M, the guillotine 25 and the welding means 26 is schematic in figure 7 and other embodiments are possible and in particular with means for acting on a tape 10 outside the distributor 20.
[0062] Les figures 8 et 9 illustrent une forme de réalisation particulière de l'invention. Le dispositif 1 comprend trois modules 4. Le premier module 4 comprend quatre distributeurs 20 de ruban 10 qui déposent chacun un ruban 10 dans le sens d'avancement X, c'est-à-dire que l'angle entre le ruban 10 et le guide principal 3 a une valeur de 0 degré. Le deuxième module 4 comprend deux distributeurs 20 de ruban 10 et enfin le troisième module 4 comprend un seul distributeur 20 de ruban 10. Cette forme de réalisation n'est pas limitative pour l'invention. Figures 8 and 9 illustrate a particular embodiment of the invention. The device 1 comprises three modules 4. The first module 4 comprises four distributors 20 of ribbon 10 which each deposit a ribbon 10 in the direction of advance X, that is to say that the angle between the ribbon 10 and the main guide 3 has a value of 0 degrees. The second module 4 comprises two dispensers 20 of tape 10 and finally the third module 4 comprises a single dispenser 20 of tape 10. This embodiment is not limiting for the invention.
[0063] Afin de fabriquer un élément allongé 11 selon l'invention, une première étape consiste à mettre en œuvre des moyens d'alimentation 6 sur chacun des modules 4 du dispositif 1. A ses fins, selon les exemples illustrés, des bobines 21 comprenant chacune un ruban 10 choisis sont disposés sur chaque couronne d'alimentation 5 du dispositif 1. De préférence, les bobines délivrent le même ruban 10 par module et chaque module 4 peut comprendre des bobines de ruban 10 de type différent. In order to manufacture an elongated element 11 according to the invention, a first step consists in implementing supply means 6 on each of the modules 4 of the device 1. For its purposes, according to the examples illustrated, coils 21 each comprising a chosen ribbon 10 are arranged on each supply crown 5 of the device 1. Preferably, the reels deliver the same ribbon 10 per module and each module 4 can comprise reels of ribbon 10 of different types.
[0064] Selon l'exemple illustré aux figures 8 et 9, les rubans 10 utilisés ont une largeur comprise entre 20 et 10 mm et une épaisseur d'environ 150 microns. According to the example illustrated in Figures 8 and 9, the strips 10 used have a width of between 20 and 10 mm and a thickness of approximately 150 microns.
[0065] Une deuxième étape du procédé consiste à paramétrer, d'une part, la vitesse d'avancée VI et, d'autre part, la vitesse de rotation V2 de chacun des modules 4. Le paramétrage précis et coordonnée de ces deux valeurs permet de définir pour chaque moyen d'alimentation 6 un angle voulu entre le ruban 10 et le guide principal 3, cet angle varie entre -90 et 90° en excluant ces deux limites d'intervalle. Par exemple, et selon l'exemple du dispositif illustré aux figures 8 et 9, une première couche de ruban 10 est déposée avec un angle proche de 0° par rapport à la direction X, une deuxième couche de ruban 10 est déposée avec un angle d'environ 80° par rapport à la direction X et une troisième couche est déposée avec un angle proche de -80° par rapport à la direction X. A second step of the process consists in setting, on the one hand, the speed of advance VI and, on the other hand, the speed of rotation V2 of each of the modules 4. The precise and coordinated setting of these two values makes it possible to define for each supply means 6 a desired angle between the tape 10 and the main guide 3, this angle varies between -90 and 90° excluding these two interval limits. For example, and according to the example of the device illustrated in FIGS. 8 and 9, a first layer of ribbon 10 is deposited with an angle close to 0° with respect to the direction X, a second layer of ribbon 10 is deposited with an angle of approximately 80° with respect to the X direction and a third layer is deposited with an angle close to -80° with respect to the X direction.
[0066] Un exemple de paramétrage consiste à définir une vitesse d'avancée VI sensiblement égale à un mètre par minute et une vitesse de rotation V2 de deux modules 4 distribuant chacun un ruban 10 sensiblement égale à 360 tours par minute. Cet exemple n'est pas limitatif pour l'invention. An example of setting consists in defining an advance speed VI substantially equal to one meter per minute and a speed of rotation V2 of two modules 4 each distributing a tape 10 substantially equal to 360 rotations per minute. This example is not limiting for the invention.
[0067] Les modules 4 sont ensuite mis en route. The modules 4 are then started.
[0068] Selon la nature des rubans 10, un dispositif d'aide au tirage 30 est mis en œuvre afin d'aider au tirage des rubans 10 des différentes couches de l'élément 11. Selon la forme de réalisation illustrée aux figures 8 et 9, la première couche de ruban 10 issue du premier module 4 glisse sur le guide principal 3 au travers des deux autres modules 4 mis en œuvre. Les rubans 10 de la première couche peuvent glisser seuls si leur nature le permet ou avec une aide manuelle. Les rubans 10 des autres couches sont déposés sur la couche précédente et ensuite passent par le dispositif d'aide au tirage 30. Ce dispositif d'aide 30 n'est pas toujours nécessaire à la mise en œuvre du procédé mais il peut aider au glissement des différentes couches vers la direction X selon la nature des rubans 10 utilisés. Depending on the nature of the ribbons 10, a drawing aid device 30 is implemented in order to help draw the ribbons 10 from the different layers of the element 11. According to the embodiment illustrated in FIGS. 8 and 9, the first layer of tape 10 from the first module 4 slides on the main guide 3 through the two other modules 4 implemented. The tapes 10 of the first layer can slide alone if their nature allows it or with manual help. The ribbons 10 of the other layers are deposited on the previous layer and then pass through the drawing aid device 30. This aid device 30 is not always necessary for the implementation of the method but it can help sliding of the different layers towards the X direction depending on the nature of the tapes 10 used.
[0069] Selon une forme de réalisation particulière avec notamment des rubans de la première couche disposés selon un angle proche de 0° avec la direction X, il n'y a pas nécessairement besoin d'aide manuelle pour faire avancer lesdits rubans 10. According to a particular embodiment with in particular ribbons of the first layer arranged at an angle close to 0° with the direction X, there is not necessarily a need for manual assistance to advance said ribbons 10.
[0070] Une première couche de rubans 10 disposé avec un angle sensible de 0° avec la direction X par rapport au bâti 2 glisse ainsi sur le guide principal 3 longitudinal. [0070] A first layer of strips 10 arranged with a substantial angle of 0° with the direction X with respect to the frame 2 thus slides on the main longitudinal guide 3.
[0071] Selon une autre forme de réalisation, une fois que d'autres couches de rubans 10 sont superposées à la première couche, l'élément allongé 11 se fabrique sans aide et le dispositif d'aide au tirage 30 n'a plus d'utilité et peut être retiré. Il peut s'agir d'une période transitoire d'aide au démarrage qui est nécessaire si la nature du ruban 10 utilisé ne permet pas au ruban de se déployer efficacement hors de sa bobine 21. [0071] According to another embodiment, once other layers of ribbons 10 are superimposed on the first layer, the elongated element 11 is manufactured without assistance and the drawing aid device 30 no longer has to utility and can be removed. This may be a transitional period of start-up assistance which is necessary if the nature of the ribbon 10 used does not allow the ribbon to deploy effectively out of its spool 21.
[0072] L'élément allongé 11 qui se fabrique peut être stocké enroulé autour d'une bobine de stockage facilitant ainsi sa manutention ultérieure. L'élément allongé 11 peut également être découpé au fur et à mesure de sa fabrication selon la taille voulue et selon les étapes supplémentaires décrites ci-dessous, par exemple d'augmentation ou de réduction des dimensions. [0073] Selon une forme de réalisation (non illustrée) la bobine de stockage est un dispositif d'aide au tirage des rubans 10. En effet, lors de son enroulement, l'élément textile 11 entraîne le tirage des rubans 10 qui le forment. The elongated element 11 which is manufactured can be stored wrapped around a storage reel, thus facilitating its subsequent handling. The elongated element 11 can also be cut as it is manufactured according to the desired size and according to the additional steps described below, for example of increasing or reducing the dimensions. [0073] According to one embodiment (not shown), the storage reel is a device for assisting the drawing of the ribbons 10. Indeed, when it is wound, the textile element 11 causes the drawing of the ribbons 10 which form it. .
[0074] Lorsque l'élément allongé 11 est de taille voulue, on peut alors le découper. Une autre manière de terminer le procédé consiste à attendre l'épuisement des rubans 10.When the elongated element 11 is of the desired size, it can then be cut. Another way to end the process is to wait for the ribbons 10 to run out.
[0075] Un des avantages de l'utilisation du dispositif 1 selon l'invention dans le procédé de fabrication d'un élément allongé 11 textile est qu'aucune étape d'augmentation en température des rubans 10 et/ou de l'élément allongé 11 textile obtenu n'est nécessaire pour obtenir un élément allongé 11 textile solide utilisable. Il n'y a en effet pas besoin de mettre en œuvre une étape de transformation. One of the advantages of using the device 1 according to the invention in the process for manufacturing an elongated textile element 11 is that no step of increasing the temperature of the tapes 10 and/or of the elongated element 11 textile obtained is necessary to obtain an elongated element 11 usable solid textile. There is in fact no need to implement a transformation step.
[0076] L'élément allongé 11 textile et non consolidé obtenu peut enfin être récupéré. Des étapes de consolidation peuvent alors lui être appliquées, par exemple une étape de thermoformage lorsque les dimensions le permettent. Lors de la consolidation de l'élément allongé 11, il est également possible de varier légèrement les dimensions de l'élément allongé 11, notamment son périmètre, de l'ordre de 10-20 %. The elongated textile and unconsolidated element 11 obtained can finally be recovered. Consolidation steps can then be applied to it, for example a thermoforming step when the dimensions allow it. During the consolidation of the elongated element 11, it is also possible to slightly vary the dimensions of the elongated element 11, in particular its perimeter, of the order of 10-20%.
[0077] L'élément allongé 11 textile étant formé de couches de rubans 10, il est possible de prévoir une organisation particulière des orientations des rubans 10 d'une même couche et de chaque couche et des éventuels écarts entre lesdits rubans 10 d'une même couche pour anticiper une variation de périmètre de l'élément allongé 11 textile pouvant aller jusqu'à 50%. En effet, chacune des couches peut être forcée à une réorganisation angulaire indépendamment les unes des autres, la longueur de l'élément allongé 11 textile étant affectée. Une étape finale supplémentaire contraint alors l'élément allongé 11, chaque couche de rubans 10 se réoriente selon un nouvel angle, les rubans d'une même couche se rapprochent ou s'écartent, les différentes couches étant apte à glisser les unes sur les autres. The elongated textile element 11 being formed of layers of ribbons 10, it is possible to provide a particular organization of the orientations of the ribbons 10 of the same layer and of each layer and any gaps between said ribbons 10 of a same layer to anticipate a variation in the perimeter of the elongated textile element 11 of up to 50%. Indeed, each of the layers can be forced to an angular reorganization independently of each other, the length of the elongated textile element 11 being affected. An additional final step then constrains the elongated element 11, each layer of ribbons 10 reorients itself according to a new angle, the ribbons of the same layer approach or move apart, the different layers being able to slide on each other. .
[0078] Selon une forme de réalisation particulière, un guide secondaire longitudinal (non représenté) est disposé au niveau du premier module 4 pendant la fabrication. Ce guide secondaire de diamètre ou de section supérieur au diamètre ou à la section du guide principal 3 est placé en amont du premier module 4 et translate selon la direction de fabrication de l'élément allongé 11. Les rubans 10 des différents modules 4 se déposent alors sur le guide secondaire, et à nouveau sur le guide principal 3 après le passage du guide secondaire. Il est ainsi également possible d'augmenter fortement le diamètre ou la section ou encore forme globale de l'élément allongé 11 pendant sa fabrication. Un exemple d'un tel élément allongé 11 obtenu est illustré à la figure 10. According to a particular embodiment, a secondary longitudinal guide (not shown) is arranged at the level of the first module 4 during manufacture. This secondary guide of diameter or section greater than the diameter or the section of the main guide 3 is placed upstream of the first module 4 and translates according to the direction of manufacture of the elongated element 11. The ribbons 10 of the different modules 4 are deposited then on the secondary guide, and again on the main guide 3 after the passage of the secondary guide. It is thus also possible to greatly increase the diameter or cross-section or even the overall shape of the elongated element 11 during its manufacture. An example of such an elongated element 11 obtained is shown in Figure 10.
[0079] Avec une augmentation du diamètre ou de la section, des rubans 10 similaires aux rubans 10 alimentés par le module 4 correspondant peuvent être ajoutés grâce à des moyens de soudure 26 par ultrasons permettant ainsi de combler des ouvertures qui pourrait se former dues à l'augmentation de la surface de l'élément allongé 11, un tel exemple est illustré à la figure 10 avec des rubans 10 ajoutés sur la couche en dessous de la couche supérieure lors de l'augmentation du diamètre de l'élément 11 et des rubans 10 coupés lors de la diminution du diamètre de l'élément 11. [0080] Selon une autre forme de réalisation de l'invention, l'élément allongé 11 obtenu grâce au dispositif 1 est cintré à froid selon un angle voulu tel que l'élément allongé 11 apparait à la figure 11. Cette étape de cintrage à froid peut être faite à la main si la rigidité de flexion de l'élément allongé 11 obtenu le permet. With an increase in diameter or section, strips 10 similar to the strips 10 supplied by the corresponding module 4 can be added using ultrasonic welding means 26, thus making it possible to fill in openings which could form due to increase in the surface of the elongated element 11, such an example is illustrated in Figure 10 with ribbons 10 added on the layer below the upper layer when increasing the diameter of the element 11 and the ribbons 10 cut when the diameter of the element 11 is reduced. The elongated element 11 appears in FIG. 11. This cold bending step can be done by hand if the bending rigidity of the elongated element 11 obtained allows it.
[0081] Selon une autre forme de réalisation non illustrée, l'élément allongé 11 peut également être consolidé en intégrant une matrice solide au niveau d'une des couches de ruban 10 le composant. According to another embodiment not illustrated, the elongated element 11 can also be consolidated by integrating a solid matrix at one of the layers of tape 10 that makes it up.
[0082] Bien entendu, diverses autres modifications peuvent être apportées à l'invention dans le cadre des revendications annexées. Of course, various other modifications can be made to the invention within the scope of the appended claims.
