  • the method and the device described in this document can directly prepare solid or tubular profiles regardless of their section.
  • the new technical problem to be solved is to be able to manufacture tubes of very great length, generally limited only by the dimensions of the factory or possibly transport. Regarding the invention, it is possible to manufacture tubes longer than 30 meters and up to 100 meters or more.
  • the invention is not limited to the manufacture of circular section tubes but can be used to manufacture other profiles such as sections of flat or square section, boat masts, wind turbine blades.
  • the invention still makes it possible to manufacture tubes in a manner freed from the geometry of the section of the tube.

As regards the use of thermoplastic resin, the mechanical strength is much higher, particularly with respect to the impact resistance, compared to the use of thermosetting resin.
  • thermoplastic resin also allows greater ease of realization of the tubes. Since the invention produces elongated elements, such as tubes or tubular elements, with a thermoplastic resin, their use must be limited in places where the temperature must not exceed 100 ° C., that is to say either in the soil , or at sea where an interesting application is off-shore especially for oil installations. In the case of the production of tubes which can reach a length of 100 m, these are then connected together by connector devices which may be metallic to ensure a perfect seal, devices of this type being commercially available in particular from Freyssinet International domiciled in France.

Description

ELEMENTS ALLONGES RENFORCES TELS QUE DES TUBES, PROCEDE ET APPAREIL POUR LEUR FABRICATION ET UTILISATION DE CES ELEMENTS ALLONGESREINFORCED ELONGATED ELEMENTS SUCH AS TUBES, PROCESS AND APPARATUS FOR MAKING AND USING THE SAME
L'invention concerne le domaine technique de fabrication d'éléments allongés, tels que des tubes, par exemples tubes off-shore. Jusqu'à présent, il a été réalisé la fabrication de tubes en acier très lourds qui ont des problèmes de corrosion en milieu marin, et qui sont également difficiles à souder.The invention relates to the technical field of manufacturing elongated elements, such as tubes, for example off-shore tubes. So far, it has been realized the manufacture of very heavy steel tubes which have problems of corrosion in the marine environment, and which are also difficult to weld.
On connaît aussi par le document FR-A-2.031.719 (Société du Verre Textile) déposé le 5 février 1969, un procédé et un dispositif pour l'obtention de produits composés de fibres agglomérées par des résines synthétiques, en particulier, des résines thermoplastiques.Document FR-A-2.031.719 (Société du Verre Textile), filed February 5, 1969, discloses a method and a device for obtaining products composed of fibers agglomerated with synthetic resins, in particular resins. thermoplastics.
Le procédé et le dispositif décrits dans ce document permettent de préparer directement des profilés pleins ou tubulaires quelles que soient leur section.The method and the device described in this document can directly prepare solid or tubular profiles regardless of their section.
BUTS DE L'INVENTIONGOALS OF THE INVENTION
Le nouveau problème technique à résoudre est de pouvoir fabriquer des tubes de très grande longueur, en général limités uniquement par les dimensions de l'usine ou éventuellement du transport. Concernant l'invention, il est possible de fabriquer des tubes d'une longueur supérieure à 30 mètres et pouvant aller jusqu'à 100 mètres voire plus.The new technical problem to be solved is to be able to manufacture tubes of very great length, generally limited only by the dimensions of the factory or possibly transport. Regarding the invention, it is possible to manufacture tubes longer than 30 meters and up to 100 meters or more.
L'invention n'est pas limitée à la fabrication de tubes de section circulaire mais peut être utilisée pour fabriquer d'autres profilés tels que des profilés de section plate ou carrée, des mats de bateau, des pales d'éolienne.The invention is not limited to the manufacture of circular section tubes but can be used to manufacture other profiles such as sections of flat or square section, boat masts, wind turbine blades.
L'invention permet encore de fabriquer des tubes de manière affranchie de la géométrie de la section du tube. Cette géométrie peut être d'une forme quelconque.The invention still makes it possible to manufacture tubes in a manner freed from the geometry of the section of the tube. This geometry can be of any shape.
Un autre problème technique que l'invention vise à résoudre est la fabrication de tube à l'aide de résine thermoplastique et non pas thermodurcissable.Another technical problem that the invention aims to solve is the manufacture of tube using thermoplastic resin and not thermosetting.
L'invention vise ainsi à remplacer les tubes en acier très lourds qui ont des problèmes de corrosion et également difficiles à souder. Dans la structure off-shore de type métallique, au-delà d'une certaine longueur comme par exemple 1500 m de profondeur, le poids est tellement important que ces structures ne résistent pas à leur propre poids.The invention thus aims to replace the very heavy steel tubes which have corrosion problems and also difficult to weld. In the offshore structure of metal type, beyond a certain length such as 1500 m deep, the weight is so important that these structures do not withstand their own weight.
L'invention permet aussi de résoudre ce problème. Selon un premier aspect, la présente invention couvre, à titre de produit nouveau, un élément allongé renforcé, comprenant une âme de forme allongée, recouverte d'au moins une couche à matériau composite comprenant une pluralité de rubans enroulés autour de ladite âme, chacun des rubans étant réalisé à l'aide de fils ou de fibres de renforcement, par exemple des fils ou fibres de verre ou de carbone, noyés dans une matrice en résine thermoplastique. Ces fils ou fibres de renforcement sont de préférence continus. Ainsi, les fils ou fibres sont avantageusement de grande longueur en général correspondant sensiblement à la longueur des rubans.The invention also solves this problem. According to a first aspect, the present invention covers, as new product, a reinforced elongated element, comprising an elongated core, covered with at least one layer of composite material comprising a plurality of ribbons wound around said core, each ribbons being made using son or reinforcing fibers, for example son or fiberglass or carbon, embedded in a thermoplastic resin matrix. These son or reinforcing fibers are preferably continuous. Thus, the son or fibers are advantageously of great length generally corresponding substantially to the length of the ribbons.
Dans le cadre de l'invention, la résine thermoplastique elle-même est disponible dans le commerce, sous forme de granulés. Egalement , en ce qui concerne la fabrication du ruban utilisé selon l'invention, on peut utiliser le procédé et l'appareil tels que décrits dans le document FR-A-2.031.719 cité ci-dessus. Naturellement, d'autres techniques de fabrication de ruban de ce type peuvent être utilisées. Concernant l'utilisation de résine thermoplastique, la résistance mécanique est beaucoup plus élevée notamment à la résistance aux chocs, par rapport à l'utilisation de résine thermodurcissable.In the context of the invention, the thermoplastic resin itself is commercially available in the form of granules. Also, with regard to the manufacture of the ribbon used according to the invention, the method and the apparatus as described in document FR-A-2,031,719 mentioned above can be used. Of course, other ribbon making techniques of this type can be used. As regards the use of thermoplastic resin, the mechanical strength is much higher, particularly with respect to the impact resistance, compared to the use of thermosetting resin.
L'utilisation de résine thermoplastique permet aussi une plus grande facilité de réalisation des tubes. Comme l'invention fabrique des éléments allongés , tels que des tubes ou éléments tubulaires, avec une résine thermoplastique, leur utilisation doit être limitée dans des lieux où la température ne doit pas excéder 1000C, c'est à dire soit dans le sol, soit en mer où une application intéressante est en off-shore notamment pour les installations pétrolières. Dans le cas de la réalisation de tubes qui peuvent atteindre une longueur de 100 m, ceux-ci sont ensuite connectés entre eux par des dispositifs connecteurs qui peuvent eux être métalliques de manière à assurer une étanchéité parfaite, des dispositifs de ce type étant disponibles dans le commerce notamment auprès de la société Freyssinet International domiciliée en France.The use of thermoplastic resin also allows greater ease of realization of the tubes. Since the invention produces elongated elements, such as tubes or tubular elements, with a thermoplastic resin, their use must be limited in places where the temperature must not exceed 100 ° C., that is to say either in the soil , or at sea where an interesting application is off-shore especially for oil installations. In the case of the production of tubes which can reach a length of 100 m, these are then connected together by connector devices which may be metallic to ensure a perfect seal, devices of this type being commercially available in particular from Freyssinet International domiciled in France.
Selon une variante de réalisation, l'âme de forme allongée précitée est réalisée en un métal ou un alliage de métal, notamment en acier, de préférence inoxydable.According to an alternative embodiment, the aforementioned elongated core is made of a metal or a metal alloy, in particular steel, preferably stainless.
Selon une autre variante de réalisation, l'âme est réalisée en un matériau thermoplastique, en particulier « nylon », de préférence de même nature que la résine thermoplastique servant à réaliser la matrice du ruban. Selon encore une autre variante de réalisation, la résine thermoplastique comprend ou est constituée de polyamide 11 ou de polyamide 12.According to another embodiment, the core is made of a thermoplastic material, in particular "nylon", preferably of the same nature as the thermoplastic resin used to make the matrix of the ribbon. According to yet another variant embodiment, the thermoplastic resin comprises or consists of polyamide 11 or polyamide 12.
Selon encore un mode de réalisation avantageux de l'invention, l'âme précitée présente une forme essentiellement convexe. Selon un mode de réalisation actuellement préféré, l'âme de forme allongée présente principalement ou essentiellement une forme tubulaire creuse de type tube.According to another advantageous embodiment of the invention, the aforementioned core has a substantially convex shape. According to a presently preferred embodiment, the elongated core essentially or essentially has a tube-like hollow tubular shape.
Selon un mode de réalisation avantageux de l'invention, les rubans sont enroulés autour de l'âme selon un angle prédéterminé par rapport à l'axe longitudinal de l'élément allongé, selon la résistance mécanique souhaitée pour l'application envisagée.According to an advantageous embodiment of the invention, the tapes are wound around the core at a predetermined angle with respect to the longitudinal axis of the elongated element, according to the desired mechanical strength for the intended application.
Par exemple, cet angle sera compris entre 20° et 70°. Pour des applications "type off-shore", l'angle envisagé est actuellement compris entre 30 et 60°. Pour des applications de type "pale d'éolienne", l'angle envisagé est actuellement compris entre 20 et 70°.For example, this angle will be between 20 ° and 70 °. For "off-shore" applications, the angle envisaged is currently between 30 and 60 °. For applications of the "wind turbine blade" type, the angle envisaged is currently between 20 and 70 °.
Selon un mode de réalisation avantageux, on peut prévoir au moins une et de préférence plusieurs couches d'un matériau composite de même nature ou de nature différente, notamment de rubans différents ou disposés selon des angles d'enroulement différents.According to an advantageous embodiment, it is possible to provide at least one and preferably several layers of a composite material of the same nature or of a different nature, in particular different ribbons or arranged at different winding angles.
Selon encore un autre mode de réalisation en particulier, on peut prévoir au moins une couche réalisée en un matériau composite comprenant une résine thermoplastique et utilisant comme renfort des fibres de verre, lesdites fibres de verre pouvant être enroulées selon des angles d'enroulement pré-déterminés autour de la couche précédente.According to yet another embodiment in particular, it is possible to provide at least one layer made of a composite material comprising a thermoplastic resin and using as reinforcement glass fibers, said glass fibers being able to be wound at predetermined winding angles around the previous layer.
Selon encore un autre mode de réalisation avantageux, on prévoit que la couche la plus externe sur l'élément allongé est réalisée en matériau composite comprenant une pluralité de rubans également enroulés autour de la couche précédente, lesdits rubans comprenant une matrice en résine thermoplastique et une matière de renfort sous forme de fils ou de fibres, de verre ou de carbone.According to yet another advantageous embodiment, it is expected that the outermost layer on the elongated element is made of composite material comprising a plurality of ribbons also wound around the previous layer, said ribbons comprising a thermoplastic resin matrix and a reinforcement material in the form of yarns or fibers, glass or carbon.
Grâce à l'invention, il n'est plus nécessaire d'avoir une couche de protection des éléments allongés, la couche en matériau composite thermoplastique constituant elle-même une couche de protection grâce à sa résistance mécanique, notamment à sa résistance aux chocs.Thanks to the invention, it is no longer necessary to have a protective layer of the elongated elements, the layer of thermoplastic composite material itself constituting a protective layer due to its mechanical strength, including its impact resistance.
On observera que, dans les essais de résistance aux chocs, pour des résines thermodurcissables du type "epoxy", l'énergie nécessaire pour aboutir à une rupture est en général 5 fois plus faible que celle qui est nécessaire pour obtenir une rupture dans le cadre des résines thermoplastiques. Ce qui démontre l'intérêt de pouvoir réaliser des éléments allongés avec des résines thermoplastiques comme dans le cas de la présente invention. Selon un deuxième aspect, la présente invention concerne également un procédé de fabrication d'éléments allongés renforcés, caractérisé en ce qu'il comprend : a. La prévision d'un élément de support d'une âme de forme allongée, comportant des moyens permettant de réaliser un mouvement de translation de ladite âme de forme allongée ; b. La prévision d'au moins une cassette et avantageusement plusieurs cassettes de stockage de rubans réalisés en matériau composite comprenant une matrice en résine thermoplastique dans laquelle sont noyés des fils ou fibres de renforcement, par exemple des fils ou fibres de verre ou de carbone, c. La prévision de moyens de mise en rotation de chaque cassette. d. La prévision de moyens de synchronisation des moyens de déplacement en translation de l'âme de forme allongée et des moyens de mise en rotation de chaque cassette de ruban. e. La prévision d'au moins un dispositif de chauffage à une température supérieure à la température de fusion de la résine thermoplastique pendant une période de temps suffisante pour réaliser la fusion complète de la résine thermoplastique et le collage de la couche en matière composite sur ladite âme ou sur la couche précédente. f. On réalise, de manière synchronisée, le déplacement en translation de l'âme de forme allongée avec l'enroulement synchronisé selon un angle prédéterminé, d'au moins un ruban par mise en rotation d'au moins une cassette de stockage du ruban ; g. On réalise la formation d'une couche soit par le déroulement d'un nombre de rubans suffisant pour former ladite couche, soit en réalisant plusieurs passages en translation de ladite âme pour réaliser l'enroulement desdits rubans, h. On refroidit ou on laisse refroidir, après ledit chauffage, en obtenant ainsi l'élément allongé renforcé.It will be observed that, in the impact resistance tests, for thermosetting resins of the "epoxy" type, the energy required to break is generally 5 times lower than that necessary to obtain a rupture in the frame. thermoplastic resins. This demonstrates the advantage of being able to produce elongated elements with thermoplastic resins as in the case of the present invention. According to a second aspect, the present invention also relates to a method of manufacturing reinforced elongated elements, characterized in that it comprises: a. Providing a support member of an elongated core having means for translational movement of said elongated core; b. The provision of at least one cassette and advantageously several tape storage cassettes made of composite material comprising a thermoplastic resin matrix in which reinforcement fibers or fibers are embedded, for example glass or carbon fibers or fibers, c . The provision of means for rotating each cassette. d. The provision of means for synchronizing the displacement means in translation of the elongate core and means for rotating each ribbon cassette. e. Providing at least one heater at a temperature above the melting temperature of the thermoplastic resin for a period of time sufficient to complete melting of the thermoplastic resin and bonding the composite material layer to said core or on the previous layer. f. The movement in translation of the elongate core with the synchronized winding at a predetermined angle is carried out synchronously with at least one ribbon by rotating at least one ribbon storage cassette; boy Wut. The formation of a layer is carried out either by the unwinding of a sufficient number of ribbons to form said layer, or by carrying out several passages in translation of said core to effect the winding of said ribbons, h. Cooling or allowing to cool, after said heating, thereby obtaining the reinforced elongate member.
Eventuellement, on peut recommencer l'opération pour déposer une couche supplémentaire ou une pluralité de couches avec des rubans de nature différente.Optionally, the operation can be repeated to deposit an additional layer or a plurality of layers with ribbons of different nature.
Avantageusement, on prévoit des moyens de réglage de l'angle de déroulement de chaque ruban autour de ladite âme.Advantageously, means are provided for adjusting the unfolding angle of each ribbon around said core.
Selon un mode avantageux de procédé de l'invention, on prévoit plusieurs dispositifs successifs de supports de cassette desdits rubans, afin de réaliser en un seul mouvement de translation de l'âme ou de l'élément de forme allongée, le dépôt de plusieurs couches en matériau composite.According to an advantageous method of the invention, there are several successive arrangements of cassette holders of said ribbons, in order to achieve in a single translational movement of the core or the elongated element, the deposition of several layers made of composite material.
Selon un mode avantageux de réalisation de l'invention, on réalise l'enroulement de chaque ruban avec une tension prédéterminée, par exemple une force de traction d'environ un décanewton (un kilo) par ruban de manière à ce que, lorsque la résine thermoplastique est en fusion, il se réalise un auto-effet de déplacement vers le centre donc vers l'âme des fils ou fibres noyés dans la résine de chaque ruban, par un effet de tension interne, d'où un effet de placage sur l'âme ou la couche précédente. Selon l'invention, le dispositif de chauffage de la résine thermoplastique est orienté de façon à éviter un chauffage de l'âme ou de la couche précédente, afin de ne pas la dégrader.According to an advantageous embodiment of the invention, the winding of each ribbon is carried out with a predetermined tension, for example a tensile force of about one decanewton (one kilogram) per ribbon so that, when the resin thermoplastic is in fusion, it is realized a self-effect of displacement towards the center thus towards the core of the son or fibers embedded in the resin of each ribbon, by an effect of internal tension, from where a plating effect on the soul or the previous layer. According to the invention, the heating device of the thermoplastic resin is oriented so as to avoid heating the core or the previous layer, so as not to degrade it.
Selon un mode de réalisation avantageux de l'invention, le chauffage est réalisé à l'aide de buses diffusant un air chaud à une température au minimum supérieure à la température de fusion de la résine thermoplastique utilisée.According to an advantageous embodiment of the invention, the heating is carried out using nozzles diffusing a hot air at a temperature at least higher than the melting temperature of the thermoplastic resin used.
L'invention permet donc d'utiliser uniquement de l'air chaud par nature moins agressif vis à vis de la matrice qu'une flamme utilisée dans la technique antérieure.The invention therefore makes it possible to use only hot air that is inherently less aggressive with respect to the matrix than a flame used in the prior art.
Selon un mode de réalisation avantageux de l'invention, on utilise un élément allongé de forme tubulaire de section quelconque polygonale ou circulaire, avantageusement creux de manière à former des tubes ou canalisations pour le transport de matériau, en particulier de fluide, notamment du pétrole ou du gaz liquide ou non.According to an advantageous embodiment of the invention, an elongated element of tubular form of arbitrary polygonal or circular cross-section is used, advantageously hollow so as to form tubes or pipes for the transport of material, in particular fluid, in particular oil. or liquid gas or not.
L'invention n'est pas limitée par une forme particulière de l'élément allongé car, grâce à l'emploi de rubans, ceux-ci épousent toute forme géométrique. L'invention est cependant avantageusement utilisée pour renforcer des âmes de forme essentiellement convexes, c'est à dire ne comportant pas de creux sur leur surface externe, creux sur lesquels il est extrêmement difficile d'appliquer lesdits rubans.The invention is not limited by a particular form of the elongate element because, thanks to the use of ribbons, these fit any geometric shape. The invention is however advantageously used to reinforce souls of substantially convex shape, that is to say having no hollow on their outer surface, hollow on which it is extremely difficult to apply said ribbons.
Selon un troisième aspect, la présente invention couvre aussi un appareil de fabrication d'éléments allongés renforcés, caractérisé en ce qu'il comprend : a. La prévision d'un élément de support d'une âme de forme allongée, comportant des moyens permettant de réaliser un mouvement de translation de ladite âme de forme allongée ; b. La prévision d'au moins une cassette et avantageusement plusieurs de cassettes de stockage de rubans réalisés en matériau composite comprenant une matrice en résine thermoplastique dans laquelle sont noyés des fils ou fibres de verre ou de carbone, c. La prévision de moyens de mise en rotation de chaque cassette. d. La prévision de moyens de synchronisation des moyens de déplacement en translation de l'âme de forme allongée et des moyens de mise en rotation de chaque cassette de ruban. e. La prévision d'au moins un dispositif de chauffage à une température supérieure à la température de fusion de la résine thermoplastique pendant une période de temps suffisante pour réaliser la fusion complète de la résine thermoplastique et le collage de la couche en matière composite sur ladite âme ou sur la couche précédente. f. La prévision de moyens de commande, de manière synchronisée, des moyens de synchronisation des moyens de déplacement en translation de l'âme de forme allongée et des moyens de mise en rotation de chaque cassette de ruban ; ces moyens de commande étant prévus soit pour réaliser le déroulement d'un nombre de rubans suffisant pour former au moins une couche en matériau composite comprenant une pluralité de rubans enroulés autour de l'âme de forme allongée, soit pour réaliser plusieurs passages en translation de ladite âme pour réaliser un enroulement desdits rubans ; g. Lesdits moyens de commande étant prévus pour commander chaque dispositif de chauffage à une température supérieure à une température de fusion de la résine thermoplastique pendant une période de temps suffisante pour réaliser la fusion complète de la résine thermoplastique et les collages d'une couche en matière composite sur ladite âme ou sur la couche précédente.According to a third aspect, the present invention also covers an apparatus for manufacturing reinforced elongated elements, characterized in that it comprises: a. Providing a support member of an elongated core having means for translational movement of said elongated core; b. The provision of at least one cassette and advantageously a plurality of tape storage cassettes made of composite material comprising a thermoplastic resin matrix in which glass or carbon fibers or fibers are embedded, c. The provision of means for rotating each cassette. d. The provision of means for synchronizing the displacement means in translation of the elongate core and means for rotating each ribbon cassette. e. Providing at least one heater at a temperature above the melting temperature of the thermoplastic resin for a period of time sufficient to complete melting of the thermoplastic resin and bonding the composite material layer to said core or on the previous layer. f. The provision of control means, in synchronized manner, means for synchronizing the displacement means in translation of the elongated core and means for rotating each tape cassette; these control means being provided either to perform the unwinding of a sufficient number of ribbons to form at least one layer of composite material comprising a plurality of ribbons wound around the elongated core, or to perform several translation passages of said core for winding said ribbons; boy Wut. Said control means being provided for controlling each heating device at a temperature above a melting temperature of the thermoplastic resin for a period of time sufficient to effect the complete melting of the thermoplastic resin and the bonding of a composite material layer. on said soul or on the previous layer.
Dans le cas de l'appareil de l'invention, pour accélérer le refroidissement de l'élément allongé renforcé obtenu, il peut être prévu des moyens de refroidissement en aval du ou des dispositif(s) de chauffage.In the case of the apparatus of the invention, to accelerate the cooling of the reinforced elongated element obtained, cooling means may be provided downstream of the heating device (s).
Sur une variante de réalisation de l'appareil de l'invention, l'appareil peut être prévu pour permettre de recommencer l'opération pour déposer une couche supplémentaire ou une pluralité de couches avec des rubans de nature différente. Dans ce cadre, il peut être prévu au moins un deuxième ensemble d'au moins une cassette et avantageusement de plusieurs cassettes de stockage de rubans soit de nature identique, soit de nature différente. Ainsi, selon un mode avantageux de l'appareil de l'invention, on prévoit plusieurs dispositifs successifs de support de cassettes desdits rubans, afin de réaliser en un seul mouvement de translation d'un élément de forme allongée et le dépôt de plusieurs couches en matériaux composites.In an alternative embodiment of the apparatus of the invention, the apparatus may be provided to allow the operation to be repeated to deposit an additional layer or a plurality of layers with ribbons of different nature. In this context, it may be provided at least a second set of at least one cassette and advantageously several tape storage cassettes of identical nature or different nature. Thus, according to an advantageous embodiment of the apparatus of the invention, provision is made for several successive devices for supporting cassettes of said ribbons, in order to achieve in a single translational movement of an elongated element and the deposition of several layers in composite materials.
Selon un autre mode de réalisation avantageux de l'appareil selon l'invention, on peut prévoir des moyens de réglage de tension à une valeur prédéterminée de l'enroulement de chaque ruban, par exemple en prévoyant que ces moyens de réglage de tension permettent d'effectuer un réglage et une force de traction d'environ un décanewton (un kilo) par ruban, de manière à ce que, lorsque la résine thermoplastique est en fusion, il se réalise un auto-effet de déplacement vers le centre donc vers l'âme des fils aux fibres noyées dans la résine de chaque ruban, par un effet de tension interne, d'où un effet de placage sur l'âme ou la couche précédente.According to another advantageous embodiment of the apparatus according to the invention, it is possible to provide means for adjusting the voltage at a predetermined value of the winding of each ribbon, for example by providing that these voltage adjustment means make it possible to adjusting and pulling force of about one decanewton (one kilogram) per ribbon, so that when the thermoplastic resin is melted, an auto-effect of movement towards the center, thus toward the fiber core embedded in the resin of each ribbon, by an internal tension effect, hence a plating effect on the soul or the previous layer.
Selon un mode de réalisation avantageux de l'invention, le dispositif de chauffage de la résine thermoplastique est orienté de façon à éviter un chauffage de l'âme ou de la couche précédente, afin de ne pas la dégrader. Selon encore un autre mode de réalisation avantageux de l'appareil selon l'invention, on peut prévoir que le dispositif de chauffage comprend des buses diffusant un air chaud à une température au minimum supérieure à la température de fusion de la résine thermoplastique utilisée. Selon un quatrième aspect, la présente invention couvre encore l'utilisation des éléments allongés renforcés précités, en particulier obtenus par le procédé selon l'invention ou l'appareil de fabrication de l'invention, pour la fabrication de canalisations enterrées dans le sol ou utilisées en off-shore en particulier sur les fonds marins. On comprend ainsi que l'invention permet bien de résoudre les problèmes techniques précédemment énoncés et, par conséquent, une solution nouvelle et non évidente pour un homme de l'art.According to an advantageous embodiment of the invention, the heating device of the thermoplastic resin is oriented so as to avoid heating the core or the previous layer, so as not to degrade. According to yet another advantageous embodiment of the apparatus according to the invention, it can be provided that the heating device comprises nozzles diffusing a hot air at a temperature at least greater than the melting temperature of the thermoplastic resin used.
