Abstract

The reinforcement for a deformable preform for a tubular section (2a) is made from a strip (3, 11) of structured filamentary material, wound upon itself in order to form a multi-layer cylinder, the layers (3a, 3b) thus formed being joined along at least one generatrix of the cylinder.

Description

Dans les brevets français n0 90 06269 et 90 13053 du déposant, il est fait état d'un dispositif pour réaliser sur place des tronçons de tubage ou de canalisation, à partir d'une préforme qui possède certaines caractéristiques notamment de structure. In the French patents Nos. 90 06269 and 90 13053 of the applicant, mention is made of a device for producing on-site sections of casing or pipe, from a preform which has certain characteristics, in particular of structure.

t'une de ces caractéristiques réside dans la constitution même de la paroi tubulaire de la préforme qui, tout en étant relativement épaisse, doit être déformable afin d'être pliée pour occuper un volume minimal avant mise en place. one of these characteristics resides in the very constitution of the tubular wall of the preform which, while being relatively thick, must be deformable in order to be folded to occupy a minimum volume before installation.

Pour atteindre ce résultat, la paroi de la préforme, conformément à ces brevets, met en oeuvre une pluralité de structures filamentaires du genre manches issues d'un tissage de fibres circonférentielles avec des fibres longitudinales, de manière que ces manches, étant enfilées les unes dans les autres, forment une sorte d'armature relativement épaisse mais de section transversale déformable sans être extensible pour autant. Chaque manche, pour que la section transversale de la paroi soit déformable, doit donc pouvoir glisser par rapport à ses voisines. To achieve this result, the wall of the preform, in accordance with these patents, implements a plurality of filamentary structures of the sleeve type resulting from a weaving of circumferential fibers with longitudinal fibers, so that these sleeves, being threaded together in the others, they form a kind of relatively thick reinforcement but of deformable cross section without being extensible. Each sleeve, so that the cross section of the wall is deformable, must therefore be able to slide relative to its neighbors.

Un même résultat peut être obtenu selon la présente invention et ce de manière plus simple pour ce qui concerne la fabrication de cette structure multicouche à couches glissantes les unes par rapport aux autres. The same result can be obtained according to the present invention and this in a simpler manner as regards the manufacture of this multilayer structure with sliding layers with respect to each other.

A cet effet, la présente invention a pour premier objet l'armature elle-même de préforme déformable pour section tubulaire, qui est issue d'une bande en matériau filamentaire structuré, enroulée sur elle-même pour former un cylindre multicouche, les couches ainsi formées étant réunies le long d'au moins une génératrice du cylindre. De manière avantageuse, la laison des couches entre elles sera réalisée par couture.  For this purpose, the present invention firstly relates to the frame itself of deformable preform for tubular section, which comes from a strip of structured filamentary material, wound on itself to form a multilayer cylinder, the layers thus formed being joined along at least one generatrix of the cylinder. Advantageously, the layers are layered together by sewing.

Il faut entendre par bande de matériau filamentaire structuré, une bande constituée par l'assemblage de fils ou de nappes de fils croisés perpendiculairement ou non, par tissage, collage ou tout moyen adéquat. The term “strip of structured filamentary material” should be understood to mean a strip formed by the assembly of threads or layers of threads crossed perpendicularly or not, by weaving, gluing or any suitable means.

Dans un mode de réalisation, la largeur de la bande correspond à la longueur du tronçon et l'enroulement s'opère autour d'un axe perpendiculaire à la direction longitudinale de la bande. Cette réalisation ne permet pas de produire une longueur illimitée d'armature. C'est pourquoi un second objet de l'invention est une bande de matériau pour réaliser l'armature précédente par enroulement hélicoïdal de manière à produire l'armature en continu. Cette bande estremarquable en ce qu'elle présente un bord longitudinal de longueur plus importante que l'autre. On peut ainsi obtenir une paroi multicouche épaisse, chaque couche s'étendant de la surface intérieure de l'armature à la surface extérieure de celleci. In one embodiment, the width of the strip corresponds to the length of the section and the winding takes place around an axis perpendicular to the longitudinal direction of the strip. This realization does not allow to produce an unlimited length of reinforcement. This is why a second object of the invention is a strip of material for making the previous reinforcement by helical winding so as to produce the reinforcement continuously. This strip is remarkable in that it has a longitudinal edge of greater length than the other. It is thus possible to obtain a thick multilayer wall, each layer extending from the interior surface of the frame to the exterior surface thereof.

La confection de l'armature susdite par enroulement hélicoïdal sera avantageusement réalisée grâce à un dispositif qui comporte un mandrin sur lequel on procède à l'enroulement hélicoïdal de la bande, préalablement stockée sur une bobine conique, et à l'extrémité duquel sont disposés une tête de liaison des couches bobinées le long d'une génératrice et un extracteur du tube ainsi formé. Ce dispositif peut également comporter des moyens pour recouvrir le mandrin d'uns nappe de fils longitudinaux, préalablement à l'enroulement de la bande. The aforementioned reinforcement is made by helical winding will advantageously be carried out by means of a device which comprises a mandrel on which the helical winding of the strip is carried out, previously stored on a conical coil, and at the end of which are arranged a head for connecting the layers wound along a generator and an extractor from the tube thus formed. This device may also include means for covering the mandrel with a sheet of longitudinal wires, prior to the winding of the strip.

D'autres caractéristiques et avantages de l'invention ressortiront des exemples de réalisation donnés ci-après de manière non-limitative. Other characteristics and advantages of the invention will emerge from the exemplary embodiments given below in a non-limiting manner.

Il sera fait référence aux dessins annexés dans lesquels:
- la figure 1 est une vue en coupe transversale d'un tronçon de tubage dans ses deux états -plié et déplié- qui fait apparaître la structure de la paroi,
- la figure 2 est un schéma illustrant un mode de réalisation de l'armature du tronçon de tube par enroulement hélicoïdal d'une bande de tissu ou analogue,
- les figures 3 et 4 représentent, respectivement par une vue de dessus et par une vue en bout, une variante ddu dispositif de la figure 2
Le dessin de la figure 1, qui correspond aux dessins des brevet cités en préambule, se distingue de ces dessins par le fait que la structure filamentaire formant l'armature de la paroi du tube 2a ou de la préforme 2b, ntest pas constitué par une superposition de manches mais par l'enroulement d'une bande continue 3 sur elle-même pour former des couches Jointives successives 3a et 3b.Reference will be made to the appended drawings in which:
FIG. 1 is a cross-sectional view of a section of casing in its two states - folded and unfolded - which shows the structure of the wall,
FIG. 2 is a diagram illustrating an embodiment of the reinforcement of the tube section by helical winding of a strip of fabric or the like,
- Figures 3 and 4 show, respectively by a top view and by an end view, a variant of the device of Figure 2
The drawing of FIG. 1, which corresponds to the drawings of the patents cited in the preamble, differs from these drawings by the fact that the filamentary structure forming the reinforcement of the wall of the tube 2a or of the preform 2b, is not constituted by a sleeve superposition but by winding a continuous strip 3 on itself to form successive successive layers 3a and 3b.

La structure de cette bande est identique à celle du matériau ayant servi à la confection des manches décrites dans le brevets cités en préambule et il n'en sera pas donné d'autre description. The structure of this strip is identical to that of the material used to make the sleeves described in the patents cited in the preamble and no further description will be given thereof.

Pour maintenir la cohésion de l'enroulement, on relie les couches (zone C de la figure 1) les unes aux autres le long d'une génératrice par une ou deux coutures
C1, C2. Cette liaison, comme le montre la figure 1 (points A et B), n'empêche pas le glissement nécessaire au pliage en fer-à-cheval comme représenté, ou à plat comme illustré par la figure 2 du brevet 90 13053
A la figure 2, on a représenté une bobine 10 pour une bande 11 de matériau filamentaire dont l'un des bords Ila est plus long que l'autre bord llb. Cette bande Il est enroulée hélicoidalement sur un mandrin 12, de manière à former des couches qui se chevauChe sur une gande partie de leur largeur (par exemple 90% si on veut réaliser une armature à dix couches superposées).C'est pour cette raison que l'un des bords de la bande est plus long que l'autre, ce bord long étant situé à l'extérieur de la préforme, s'enroule sur un cylindre de plus grand diamètre que le bord plus court qui s'enroule directement sur le mandrin 12. On remarquera que la bobine 10 possède un noyau conique pour permettre l'enroulement aisé de cette bande 11 particulière.To maintain the cohesion of the winding, the layers (zone C of Figure 1) are connected to each other along a generator by one or two seams
C1, C2. This connection, as shown in Figure 1 (points A and B), does not prevent the sliding necessary for folding in horseshoe as shown, or flat as illustrated by Figure 2 of patent 90 13053
In Figure 2, there is shown a coil 10 for a strip 11 of filamentary material, one of the edges Ila is longer than the other edge 11b. This strip It is helically wound on a mandrel 12, so as to form overlapping layers over a large part of their width (for example 90% if we want to make a frame with ten superimposed layers). This is for this reason that one of the edges of the strip is longer than the other, this long edge being located outside the preform, is wound on a cylinder of larger diameter than the shorter edge which is wound directly on the mandrel 12. It will be noted that the coil 10 has a conical core to allow easy winding of this particular strip 11.

Le mandrin 12 constitue la table fixe d'une machine à coudre qui effectue une piqûre 13 sur les couches enroulées. L'armature ainsi constituée est tirée axialement au moyen d'un extracteur non-représenté suivant la flèche E. The mandrel 12 constitutes the fixed table of a sewing machine which performs a stitching 13 on the wound layers. The frame thus formed is pulled axially by means of an extractor not shown according to arrow E.

A la figure 3, on retrouve la même disposition générale qu'à la figure 2, avec une opération supplémentaire, préalable à l'enroulement, qui consiste à disposer des fibres longitudinales 14 le long du mandrin 12 pour constituer un renforcement longitudinal de l'armature. In FIG. 3, the same general arrangement is found as in FIG. 2, with an additional operation, prior to winding, which consists in placing the longitudinal fibers 14 along the mandrel 12 to constitute a longitudinal reinforcement of the frame.

Les moyens pour mettre en place ces fibres (pouvant se présenter en nappe ou sous formr d'un tissu), n'ont pas été représentés.The means for placing these fibers (which may be in the form of a sheet or in the form of a fabric) have not been shown.

La figure 4, qui est une vue en bout de la figure 3, montre symboliquement les moyens 15 de réalisation de la couture 13 ainsi que le mouvement F de rotation de la bobine 10 autour du mandrin 12.  FIG. 4, which is an end view of FIG. 3, symbolically shows the means 15 for producing the seam 13 as well as the movement F of rotation of the coil 10 around the mandrel 12.
