Abstract

The cellular structure product in honeycomb form is made by assembling superposed bands of the same width. Two adjacent bands are attached to one another by a plurality of first series and second series of staples. Each of the cells of the product breaks down into two opposite portions belonging to two adjacent bands, these two portions being connected together at the edges of the cell by a first series and a second series of staples aligned according to the band width. The alignment of staples of each of the series can be done across the band width by a stapler fitted with an anvil holder offset laterally, after positioning of the anvil of the stapler under two adjacent bands. In the non-deployed product, each band is thus stapled alternately twice with a lower band and twice with an upper band.

Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne, dans le domaine du soutènement, des structures alvéolaire. L'invention concerne plus particulièrement un produit alvéolaire de bonne tenue dans le temps, un procédé et un équipement de fabrication d'un tel produit. Il est fait référence au document FR 2721334A qui est considérée comme représentant l'état de la technique le plus pertinent.The present invention relates, in the field of retaining, alveolar structures. The invention relates more particularly to a cellular product of good durability, a method and equipment for manufacturing such a product. Reference is made to the document FR 2721334A which is considered to represent the most relevant state of the art.

ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Il est connu, notamment par le document WO 95/35417 , des revêtements de protection des sols contre l'érosion, présentant des structures alvéolaires. Des bandes de textile tissé ou non tissé sont assemblées par collage ou par couture au niveau de surfaces de contact pour former les parois d'alvéoles, en forme de nid d'abeille. Dans un réseau d'alvéoles formé par plusieurs bandes (N-1, N, N+1) placées en parallèle, on comprend qu'une bande N peut se décomposer en une succession de motifs composés d'une portion (41) collée à une bande adjacente N-1, une portion (42) intermédiaire non collée, une portion (43) collée à l'autre bande adjacente N+1 et une portion (44) intermédiaire joignant le motif suivant. La figure 4 illustre cet agencement pour la réalisation d'alvéoles hexagonales. Les bandes formant le réseau d'alvéoles sont rapportées sur une structure plane (40) de support par un agrafage. Ce type de fixation requiert la formation de languettes au niveau des bords en contact avec la structure plane, ce qui complique la fabrication du produit alvéolaire.It is known, in particular by the document WO 95/35417 , soil protection coatings against erosion, with honeycomb structures. Strips of woven or non-woven fabric are bonded or stitched together at contact surfaces to form honeycomb-shaped honeycomb walls. In a network of cells formed by several bands (N-1, N, N + 1) placed in parallel, it is understood that an N-band can decompose into a succession of patterns composed of a portion (41) glued to an adjacent band N-1, an unglued intermediate portion (42), a portion (43) glued to the other adjacent band N + 1 and an intermediate portion (44) joining the next pattern. The figure 4 illustrates this arrangement for the realization of hexagonal cells. The strips forming the cell network are attached to a flat support structure (40) by stapling. This type of fastening requires the formation of tongues at the edges in contact with the flat structure, which complicates the manufacture of the cellular product.

Par ailleurs dans ce type de produit, la rigidité de la structure est obtenue à l'aide d'un procédé d'enduction des fibres des bandes dans une résine. Or il a été constaté que la rigidité diminuait dans le temps avec ce type d'imprégnation.Moreover, in this type of product, the rigidity of the structure is obtained by means of a process for coating the fibers of the strips in a resin. However, it has been found that rigidity decreases over time with this type of impregnation.

DESCRIPTION GENERALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

La présente invention a donc pour but de pallier un ou plusieurs des inconvénients de l'art antérieur en proposant un produit alvéolaire restant relativement simple de conception qui soit d'une bonne tenue dans le temps, utilisable de façon fiable pour des applications de retenue de matière (par exemple : retenue de terrain, coffrage pour du béton à couler en pente).The present invention therefore aims to overcome one or more of the drawbacks of the prior art by providing a cellular product remaining relatively simple design that is of good strength over time, reliably used for restraint applications. material (for example: ground restraint, formwork for sloping concrete).

Ce but est atteint par un produit alvéolaire, comprenant une pluralité de bandes associées entre elles pour former dans une forme déployée une structure alvéolaire en forme de nid d'abeille, le produit ayant une hauteur qui correspond à la largeur des bandes pour ladite forme déployée, caractérisé en ce que les bandes sont liées entre elles par des agrafes, chacune des alvéoles du produit étant formée par deux portions appartenant à deux bandes adjacentes, ces deux portions étant connectées entre elles par une première série et une deuxième série d'agrafes alignées suivant la largeur de bande, ces deux séries correspondant à deux arêtes de l'alvéole.This object is achieved by a cellular product, comprising a plurality of strips associated with each other to form in a deployed form a cellular honeycomb-shaped structure, the product having a height which corresponds to the width of the strips for said deployed form. , characterized in that the strips are interconnected by staples, each of the cells of the product being formed by two portions belonging to two adjacent strips, these two portions being connected together by a first series and a second series of aligned staples following the bandwidth, these two series corresponding to two edges of the cell.

Ainsi, le produit selon l'invention permet avantageusement de se passer de résine de collage tout en obtenant une structure de rigidité et résistance satisfaisante à l'état déployé.Thus, the product according to the invention advantageously makes it possible to dispense with bonding resin while obtaining a structure of rigidity and satisfactory strength in the deployed state.

Selon une autre particularité, chacune des bandes est en textile non tissé à base de fibres de polyester, aiguilleté et calandré, de l'eau pouvant être filtrée par la bande.According to another feature, each of the strips is a nonwoven fabric based on polyester fibers, needled and calendered, water that can be filtered by the strip.

Selon une autre particularité, chacune des bandes est en textile non tissé thermolié et ayant subi une thermofixation.According to another feature, each of the strips is thermofixed and thermofixed nonwoven fabric.

Selon une autre particularité, ladite première série et ladite deuxième série d'agrafes comprennent chacune entre trois et dix-huit agrafes régulièrement espacées et alignées suivant une même direction.According to another feature, said first series and said second series of staples each comprise between three and eighteen staples regularly spaced and aligned in the same direction.

Selon une autre particularité, les bandes sont dépourvues de résine d'enduction ou de collage et ont chacune une largeur déterminée comprise entre 50 et 400 mm.In another feature, the strips are devoid of coating resin or glue and each have a specific width of between 50 and 400 mm.

Selon une autre particularité, le produit alvéolaire comprend au moins une couche support reliée aux bandes du produit et en contact avec des bords des alvéoles.According to another feature, the cellular product comprises at least one support layer connected to the strips of the product and in contact with the edges of the cells.

Un objet supplémentaire de l'invention est de proposer des applications du produit alvéolaire.A further object of the invention is to propose applications of the cellular product.

A cet effet, il est proposé une utilisation du produit selon l'invention pour la protection d'un terrain contre l'érosion.For this purpose, it is proposed a use of the product according to the invention for the protection of a terrain against erosion.

Il est également proposé une utilisation du produit selon l'invention en liaison avec une couche support pour servir de coffrage perdu lors d'un coulage de matière durcissable.It is also proposed a use of the product according to the invention in connection with a support layer to serve as a formwork lost during casting hardenable material.

Un objet supplémentaire de l'invention est de proposer un procédé de fabrication de produit alvéolaire permettant de réaliser rapidement une structure alvéolaire adaptée à des applications de soutènement.A further object of the invention is to provide a foam product manufacturing method for quickly achieving a honeycomb structure suitable for retaining applications.

A cet effet, l'invention concerne un procédé de fabrication d'un produit alvéolaire, comprenant une étape d'assemblage de bandes de même largeur pour permettre de former dans une forme déployée une structure alvéolaire en forme de nid d'abeille, des bandes étant préalablement superposées, caractérisé en ce qu'il comprend une étape de liaison entre elles des bandes superposées par des agrafes, dans laquelle deux bandes adjacentes sont rattachées l'une à l'autre par une pluralité de premières séries et de deuxièmes série d'agrafes, chacune des alvéoles du produit étant formée par deux portions en vis-à-vis appartenant à deux bandes adjacentes, ces deux portions étant connectées entre elles au niveau d'arêtes de l'alvéole, par une première série et une deuxième série d'agrafes alignées suivant la largeur de bande, l'alignement d'agrafes de chacune des séries étant réalisé suivant la largeur de bande par une agrafeuse dotée d'un support d'enclume déporté latéralement, après positionnement de l'enclume de l'agrafeuse sous deux bandes adjacentes.To this end, the invention relates to a method for manufacturing a cellular product, comprising a step of assembling strips of the same width to allow forming in a deployed form a honeycomb-shaped honeycomb structure, strips being previously superimposed, characterized in that it comprises a step of linking together strips superimposed by staples, wherein two adjacent strips are attached to one another by a plurality of first series and second series of staples, each of the cells of the product being formed by two portions facing each other belonging to two adjacent strips, these two portions being connected together at the edges of the cell, by a first series and a second series of staples aligned according to the web width, the staple alignment of each of the series being bandwidth-based by a stapler having an anvil support carried laterally after positioning the anvil of the stapler in two adjacent bands.

La distance entre première série et deuxième série d'agrafes formant les arêtes d'une alvéole correspond par exemple à une constante. Cette distance longitudinale diminue naturellement lorsqu'on passe de la configuration empilée à la configuration déployée. Dans une alvéole de type hexagonale formée par une paire de bande, cette distance reste supérieure, même dans la configuration déployée, à la distance entre les deux rangées successives d'agrafes servant à accoler une paroi de cette alvéole contre une bande adjacente appartenant à une paire de bandes différente.The distance between the first series and the second series of staples forming the edges of a cell corresponds, for example, to a constant. This longitudinal distance naturally decreases when moving from the stacked configuration to the deployed configuration. In a hexagonal-shaped cell formed by a pair of bands, this distance remains greater, even in the deployed configuration, at the distance between the two rows successive staples used to attach a wall of this cell against an adjacent band belonging to a different pair of bands.

Il est ainsi obtenu une méthode permettant de réaliser par agrafage des alvéoles pour une largeur de bande relativement grande (typiquement de l'ordre de 100 mm). Pour chaque liaison entre bandes, les agrafes utilisées sont avantageusement alignées suivant la largeur de bande de façon à permettre une ouverture complète des alvéoles. Chaque opération de liaison peut être effectuée rapidement (par exemple avec 6 agrafes successivement délivrées pour former une arête droite d'alvéole), contrairement aux opérations de couture par exemple.It is thus obtained a method for stitching cells for a relatively large bandwidth (typically of the order of 100 mm). For each link between bands, the staples used are advantageously aligned along the bandwidth so as to allow complete opening of the cells. Each binding operation can be performed quickly (for example with 6 staples successively delivered to form a straight edge of cell), unlike sewing operations for example.

Selon une autre particularité, un premier ensemble et un second ensemble de moyens de guidage en translation suivant la largeur de bande sont utilisés en alternance une bande sur deux pour permettre de positionner l'agrafeuse à des niveaux en alignement d'agrafage qui sont décalés une bande sur deux, de façon à permettre la réalisation des alvéoles.According to another particularity, a first set and a second set of translational guide means along the bandwidth are used alternately every other band to enable the stapler to be positioned at staggered alignment levels which are shifted one by one. band out of two, so as to allow the realization of the cells.

Selon une autre particularité, une bande additionnelle est ajoutée, après un cycle d'agrafage, sur une superposition de bandes déjà agrafées entre elles pour permettre de commencer un cycle d'agrafage supplémentaire.According to another feature, an additional strip is added, after a stapling cycle, on a superposition of strips already stapled together to allow to start an additional stapling cycle.

Selon une autre particularité, le support d'enclume est successivement inséré dans chacune des alvéoles réalisées lors du cycle d'agrafage précédent pour permettre la fixation des agrafes lors du cycle d'agrafage en cours, le reste de l'agrafeuse étant maintenu au-dessus de la bande dernièrement ajoutée pour ce cycle en cours.According to another feature, the anvil support is successively inserted in each of the cells made during the previous stapling cycle to allow the fastening of the staples during the stapling cycle in progress, the rest of the stapler being maintained at above the band last added for this current cycle.

Un objet supplémentaire de l'invention est de proposer un équipement de fabrication de produit alvéolaire permettant de concevoir de façon simple et rapide une structure alvéolaire adaptée à des applications de soutènement.A further object of the invention is to provide an alveolar product manufacturing equipment for designing a simple and fast way a honeycomb structure suitable for supporting applications.

A cet effet, l'invention concerne un équipement de fabrication d'un produit alvéolaire, comprenant un support allongé de bandes superposées et un dispositif pour associer les bandes entre elles afin que celles-ci forment dans une forme déployée une structure alvéolaire en forme de nid d'abeille, caractérisé en ce que le dispositif est une agrafeuse dotée d'un support d'enclume allongé et déporté latéralement pour permettre d'insérer l'enclume de l'agrafeuse sous deux bandes adjacentes, par le côté et selon le sens de la largeur des bandes, l'agrafeuse comprenant un couteau mobile (en translation) permettant en association avec l'enclume, de fixer des agrafes chacune orientées suivant une orientation orthogonale à l'orientation générale du support d'enclume, l'équipement comprenant en outre des moyens d'indication d'un premier groupe et d'un second groupe de positions souhaitées pour l'agrafage, le premier groupe et le second groupe étant utilisés en alternance une bande sur deux, de façon à permettre la réalisation d'alvéoles.To this end, the invention relates to an equipment for manufacturing a cellular product, comprising an elongated support of superimposed strips and a device for associating the strips together so that these form in a deployed form a honeycomb shaped structure. Honeycomb, characterized in that the device is a stapler with an elongated anvil support and offset laterally to allow insertion of the stapler's anvil under two adjacent strips, at the side and in the widthwise direction of the strips , the stapler comprising a movable knife (in translation) allowing in association with the anvil, to fix staples each oriented in an orientation orthogonal to the general orientation of the anvil support, the equipment further comprising means of indication of a first group and a second group of desired positions for stapling, the first group and the second group being used alternately every other band, so as to allow the realization of cells.

Ainsi, l'assemblage des bandes pour former la structure alvéolaire peut être réalisée sans opération de collage préjudiciable à la conservation de la rigidité du produit ni opération de couture fastidieuse. L'agencement spécifique de l'agrafeuse permet d'obtenir des alignements d'agrafes suivant la largeur de bande qui forment les arêtes des alvéoles.Thus, the assembly of the strips to form the honeycomb structure can be achieved without gluing operation detrimental to the preservation of rigidity of the product or tedious sewing operation. The specific arrangement of the stapler provides staple alignments along the bandwidth that form the edges of the stacks.

Selon une autre particularité, l'agrafeuse est rendue solidaire d'un système mobile suivant trois directions dont deux directions orthogonales entre elles et parallèles à un plan défini par le support de bandes et une troisième direction orthogonale à ce plan.According to another feature, the stapler is secured to a mobile system in three directions, two directions orthogonal to each other and parallel to a plane defined by the support strips and a third direction orthogonal to this plane.

Ainsi le mouvement longitudinal de l'agrafeuse vers les niveaux adéquats d'agrafage ainsi que le mouvement latéral à réaliser pour la pose d'une même série d'agrafes peuvent être réalisés à l'aide d'un système mobile (par exemple motorisé et glissant sur des rails d'un bâti).Thus, the longitudinal movement of the stapler to the appropriate levels of stapling as well as the lateral movement to be carried out for laying the same series of staples can be achieved by means of a mobile system (for example motorized and sliding on rails of a frame).

Selon une autre particularité, le support (S) de bandes (B) est couplé à une pluralité de moyens de guidage (6) de l'agrafeuse (1) qui sont répartis le long du support de bandes (B) en fonction de positions souhaitées pour l'agrafage, les moyens de guidage (6) recevant une tige (tg) solidaire de l'agrafeuse (1) et parallèle au support (10) d'enclume pour guider l'agrafeuse (1) et permettre une fixation de plusieurs agrafes (1) alignées entre elles pour une position déterminée.According to another particularity, the support (S) of strips (B) is coupled to a plurality of guide means (6) of the stapler (1) which are distributed along the support strips (B) according to positions desired for stapling, the guiding means (6) receiving a rod (tg) secured to the stapler (1) and parallel to the anvil support (10) for guiding the stapler (1) and allow a fixation of several staples (1) aligned with each other for a given position.

Selon une autre particularité, le support d'enclume est relié à une extrémité d'un élément de rallonge intermédiaire, cet élément de rallonge étant maintenu écarté du reste de l'agrafeuse par un bras latéral de support rattaché à l'autre extrémité de cet élément de rallonge.According to another particular feature, the anvil support is connected to one end of an intermediate extension member, this extension member being kept apart from the rest of the stapler by a lateral support arm attached to the other end thereof. extension element.

Ainsi, une paire de bandes à attacher entre elles (situées au-dessus de l'ensemble des bandes) peut être soulevée au-dessus du support d'enclume, tout en restant bien en ligne. En effet, l'agrafeuse ne va pas entraver le maintien en ligne des bandes puisque l'élément de rallonge longitudinal est disposé sur le côté de l'empilement de bandes et un espace suffisant est laissé derrière le support d'enclume (par exemple environ 80 mm d'écart).Thus, a pair of tapes to be tied together (located above the set of tapes) can be raised over the anvil support, while remaining in line. Indeed, the stapler will not hinder the maintenance in line strips since the longitudinal extension member is disposed on the side of the stack of strips and sufficient space is left behind the anvil support (for example about 80 mm apart).

DESCRIPTION DES MODES DE REALISATION PREFERES DE L'INVENTIONDESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

En référence aux figures 1, 3 et 5, le produit alvéolaire selon l'invention est élaboré par association de plusieurs bandes (B) pouvant former dans une configuration déployée une structure alvéolaire en forme de nid d'abeille. Deux bandes (B) sont superposées sur un support (S) avant la réalisation des fixations. Comme dans la structure de la figure 4, le produit alvéolaire obtenu se compose de bandes (B) ayant la même orientation générale et se décomposant chacune en motifs élémentaires. On peut voir ainsi dans la figure 3 un motif élémentaire de bande (B) composé d'une portion accolée à une bande adjacente, une portion intermédiaire sans contact avec d'autres bandes, une portion accolée à l'autre bande adjacente et à nouveau une portion intermédiaire. Ce motif se répète plusieurs fois pour une bande (B). Chacune des alvéoles (A) du produit est formée par deux tronçons (t1, t2) en vis-à-vis appartenant à deux bandes adjacentes. Comme illustré à la figure 5, un tel tronçon (t1) comprend une portion accolée à une autre bande et deux portions intermédiaires. A la différence de la structure de la figure 4, un collage ou des coutures entre les portions de bande en contact ne sont pas nécessaires.With reference to figures 1 , 3 and 5 , the cellular product according to the invention is produced by combining several bands (B) which can form in a deployed configuration a honeycomb-shaped honeycomb structure. Two strips (B) are superimposed on a support (S) before the fastenings are made. As in the structure of the figure 4 the cellular product obtained is composed of strips (B) having the same general orientation and each of which breaks down into elementary patterns. We can see that in the figure 3 an elementary band pattern (B) composed of a portion contiguous to an adjacent band, an intermediate portion without contact with other bands, a portion contiguous to the other adjacent band and again an intermediate portion. This pattern is repeated several times for a band (B). Each of the cells (A) of the product is formed by two sections (t1, t2) vis-à-vis belonging to two adjacent bands. As illustrated in figure 5 such a section (t1) comprises a portion contiguous to another strip and two intermediate portions. Unlike the structure of the figure 4 bonding or seaming between web portions in contact is not necessary.

Les bandes (B) sont liées avantageusement entre elles par des agrafes (2) fixées suivant la direction de la largeur (20) de bande. Dans le mode de réalisation des figures 3 et 5, les deux tronçons (t1, t2) en vis-à-vis peuvent être reliés entre eux et former une alvéole (A) grâce à la présence d'une première série (s1) et d'une deuxième série (s2) d'agrafes (2) alignées suivant la largeur (20) de bande. Ces deux séries (s1, s2) correspondent donc à deux arêtes de l'alvéole (A) en forme d'hexagone. Ces deux arrêtes peuvent être considérées, de manière non limitative, comme opposées l'une à l'autre, relativement à une même alvéole. D'autres formes similaires d'alvéoles peuvent naturellement être réalisées comme peut l'apprécier l'homme du métier.The strips (B) are advantageously linked together by staples (2) fixed in the direction of the width (20) of the strip. In the embodiment of figures 3 and 5 the two sections (t1, t2) facing each other can be connected to each other and form a cell (A) by virtue of the presence of a first series (s1) and a second series (s2) of staples (2) aligned along the web width (20). These two series (s1, s2) thus correspond to two edges of the cell (A) in the shape of a hexagon. These two edges can be considered, in a nonlimiting manner, as opposed to one another, relative to the same cell. Other similar shapes of cells can of course be made as may be appreciated by those skilled in the art.

Les bandes (B) sont par exemple choisies dans un matériau de type textile non tissé, par exemple à base de fibres en polymère et aiguilleté. Pour améliorer la rigidité et la tenue dans le temps du produit alvéolaire, le matériau constitutif des bandes (B) peut être thermolié et thermofixé. La thermoliaison permet de lier les fibres entre elles, par exemple en introduisant des fibres additionnelles de liaison (consolidation thermique au coeur du produit du fait de l'incorporation de fibres passées au four), par exemple des fibres de polypropylène. La thermofixation peut consister à faire passer le matériau dans un four pour réaliser ainsi consolidation thermique de surface. Ces traitements thermiques permettent d'améliorer la résistance du matériau et d'éviter des allongements trop importants à l'usage. Le matériau de la bande (B) reste suffisamment poreux et perméable pour permettre de filtrer de l'eau. Cette perméabilisé permet à l'usage de réduire les efforts subis par le produit. Le remplissage (terre, ..) conserve ainsi sa cohésion.The strips (B) are, for example, chosen from a material of non-woven textile type, for example based on polymer and needled fibers. For to improve the rigidity and the resistance of the cellular product over time, the constituent material of the strips (B) can be thermolated and heat set. Thermolysis makes it possible to bind the fibers together, for example by introducing additional binding fibers (thermal consolidation at the core of the product due to the incorporation of fibers passed into the oven), for example polypropylene fibers. Heat-setting can consist of passing the material in an oven to achieve thermal consolidation of surface. These heat treatments make it possible to improve the resistance of the material and to avoid excessive elongations with use. The material of the strip (B) remains sufficiently porous and permeable to allow the filtration of water. This permeabilized allows the use to reduce the forces suffered by the product. The filling (earth, ..) thus retains its cohesion.

Comme exemple de matériau non tissé aiguilleté, on peut citer de manière non limitative le DUTEXIM 41-45C THU commercialisé par Tharreau Industries, qui est à base de fibres polyester. Le type de matériau choisi peut avoir subi un calandrage et une thermofixation, de manière à offrir une excellente stabilité dimensionnelle à température élevée, ainsi qu'une très bonne régularité de poids et d'épaisseur (l'épaisseur constante est par exemple typiquement de l'ordre de 2 ou 3 mm). Le calandrage permet notamment de réduire l'épaisseur.As an example of nonwoven material needled, include but not limited to DUTEXIM 41-45C THU marketed by Tharreau Industries, which is based on polyester fibers. The type of material chosen may have undergone calendering and heat-setting, so as to offer excellent dimensional stability at high temperature, as well as a very good regularity of weight and thickness (the constant thickness is, for example, typically order of 2 or 3 mm). Calendering makes it possible to reduce the thickness.

Les bandes (B) sont dépourvues de résine d'enduction ou de collage et peuvent être chacune d'une même largeur (20) déterminée comprise entre 50 et 400 mm. On comprend que le produit alvéolaire dans sa configuration déployée va avoir une hauteur qui correspond à la largeur (20) des bandes (B). A titre d'exemple, la première série (s1) et la deuxième série (s2) d'agrafes peuvent comporter chacune entre trois et dix-huit agrafes (2) régulièrement espacées. Ces agrafes (2) sont rigoureusement alignées comme illustré à la figure 3. Pour une arête formée par des agrafes en U comprenant chacune une tige centrale prolongée à ses deux extrémités par une patte du U, les pattes étant destinées à être recourbées, les tiges centrales de ces agrafes sont alignées. Les agrafes (2) sont par exemple constituées d'acier inoxydable.The strips (B) are devoid of coating resin or glue and may each be of the same width (20) determined between 50 and 400 mm. It is understood that the cellular product in its deployed configuration will have a height which corresponds to the width (20) of the strips (B). By way of example, the first series (s1) and the second series (s2) of staples may each comprise between three and eighteen staples (2) regularly spaced apart. These staples (2) are rigorously aligned as shown in FIG. figure 3 . For an edge formed by U-shaped clips each comprising a central rod extended at both ends by a tab of the U, the tabs being intended to be bent, the stems The centers of these clips are aligned. The staples (2) consist for example of stainless steel.

Le procédé et l'équipement de fabrication du produit alvéolaire vont à présent être décrits en liaison avec les figures 1, 2, et 6.The method and equipment for manufacturing the cellular product will now be described in connection with the Figures 1, 2 , and 6 .

Dans l'exemple de la figure 1, l'équipement de fabrication comprend un support (S) allongé pour recevoir les bandes (B) superposées et un dispositif d'agrafage pour associer les bandes (B) entre elles. Les bandes (B) sont empilées et peuvent former ainsi un ensemble compact. Le long de cet empilement, on vient positionner le dispositif d'agrafage, par exemple mobile longitudinalement. Dans un mode de réalisation préféré de l'invention, un rail (120) de guidage est prévu dans un bâti surélevé par rapport à la table ou support (S) où sont placées les bandes (B). Pour chaque opération d'agrafage d'une série (s1, s2) d'agrafes, un guide est prévu pour limiter le mouvement longitudinal du dispositif d'agrafage.In the example of the figure 1 , the manufacturing equipment comprises an elongate support (S) for receiving the superposed strips (B) and a stapling device for associating the strips (B) with one another. The strips (B) are stacked and can thus form a compact assembly. Along this stack, it comes to position the stapling device, for example movable longitudinally. In a preferred embodiment of the invention, a guide rail (120) is provided in a frame raised relative to the table or support (S) where the strips (B) are placed. For each staple operation of a series (s1, s2) of staples, a guide is provided to limit the longitudinal movement of the stapling device.

Ce dispositif comporte une agrafeuse (1) en ligne supportée par le bâti et rendue mobile, grâce à système mobile monté sur le bâti, suivant trois directions dont deux directions orthogonales entre elles et parallèles au plan défini par le support de bandes (B) et une troisième direction orthogonale au plan défini par le support de bandes (B). L'agrafeuse (1) doit en effet pouvoir se déplacer latéralement sur un niveau longitudinal constant pour réaliser un parfait alignement d'agrafes (2) d'une même série (s1, s2). L'agrafeuse (1) utilisée diffère d'une agrafeuse conventionnelle pour surmonter la difficulté de réaliser ce type d'agrafage sur une largeur de bande (20) pouvant accepter un alignement de plusieurs agrafes (2).This device comprises an in-line stapler (1) supported by the frame and made mobile, thanks to a mobile system mounted on the frame, in three directions, two directions orthogonal to each other and parallel to the plane defined by the support strips (B) and a third direction orthogonal to the plane defined by the support strips (B). The stapler (1) must indeed be able to move laterally on a constant longitudinal level to achieve a perfect alignment of staples (2) of the same series (s1, s2). The stapler (1) used differs from a conventional stapler in overcoming the difficulty of performing this type of stapling on a web width (20) that can accommodate an alignment of a plurality of staples (2).

Cette difficulté est surmontée en fournissant une agrafeuse (1) dotée d'un support (10) d'enclume déporté latéralement pour permettre d'insérer seulement l'enclume (100) de l'agrafeuse (1) sous deux bandes adjacentes à relier entre elles. Dans l'exemple des figures 1 et 6, l'agrafeuse (1) comporte ainsi sur un côté un U formé par trois élément

  • le support (10) d'enclume,
  • un élément de rallonge (ral) intermédiaire dont une extrémité est reliée audit support (10),
  • un bras latéral (bl) de support rattaché à l'autre extrémité de l'élément de rallonge (ral), ce bras latéral (bl) effectuant la jonction avec le reste de l'agrafeuse (1).
This difficulty is overcome by providing a stapler (1) with a laterally offset anvil support (10) to allow only the anvil (100) of the stapler (1) to be inserted under two adjacent strips to be connected between they. In the example of figures 1 and 6 , the stapler (1) thus has on one side a U formed by three elements
  • the anvil support (10),
  • an intermediate extension member (Ral), one end of which is connected to said support (10),
  • a lateral arm (bl) support attached to the other end of the extension member (ral), this lateral arm (bl) joining the rest of the stapler (1).

L'élément de rallonge (ral) est suffisamment décalé pour permettre de soulever une paire de bandes et l'introduire longitudinalement, sur toute la largeur (20) de bande, entre le support (10) d'enclume et .la sortie (13) d'agrafes (2) du corps principal (11) de l'agrafeuse (1). L'élément de rallonge (ral) reste par exemple continuellement dans une position de côté par rapport aux bandes (B) superposées lors du procédé. Le déplacement latéral de l'agrafeuse (1) est par exemple limité pour qu'un écartement latéral soit maintenu entre les bandes (B) et l'élément de rallonge (ral).The extension element (ral) is sufficiently offset to lift a pair of strips and introduce it longitudinally over the entire width (20) of the strip between the anvil support (10) and the outlet (13). ) of staples (2) of the main body (11) of the stapler (1). The extension element (ral) remains for example continuously in a position of side with respect to the strips (B) superimposed during the process. The lateral displacement of the stapler (1) is for example limited so that a lateral spacing is maintained between the strips (B) and the extension member (ral).

Pour réaliser le premier cycle d'agrafage relatif à la liaison entre deux bandes, le support (10) d'enclume est inséré sous la paire de bandes (B) comme illustré à la figure 6. Le nombre total de positions longitudinales d'agrafage est par exemple un nombre pair déterminé. On comprend, pour réaliser la structure alvéolaire, qu'un cycle d'agrafage doit se limiter à la pose d'agrafes pour seulement la moitié de ces positions, le cycle suivant étant dédié aux positions restantes. La totalité des positions d'agrafage est donc réalisée au cours de deux passages/cycles de l'agrafeuse (1), une bande (B) ayant été rajoutée sur le dessus entre les deux cycles.To perform the first stitching cycle relating to the connection between two strips, the anvil support (10) is inserted under the pair of strips (B) as shown in FIG. figure 6 . The total number of longitudinal positions of stapling is for example an even number determined. It is understood, to realize the honeycomb structure, a stapling cycle must be limited to the stapling for only half of these positions, the next cycle being dedicated to the remaining positions. All of the stapling positions are therefore performed during two passes / cycles of the stapler (1), a strip (B) having been added on top between the two cycles.

L'équipement comprend par exemple des moyens d'indication d'un premier groupe et d'un second groupe de positions souhaitées (gp1, gp2) pour l'agrafage, le premier groupe et le second groupe (gp1, gp2) étant utilisés en alternance une bande sur deux, de façon à permettre la réalisation des alvéoles (A). Ainsi, le premier cycle prévoit un agrafage pour le premier groupe de positions (gp1) et le second cycle prévoit un agrafage pour le second groupe de positions (gp2).The equipment comprises for example means for indicating a first group and a second group of desired positions (gp1, gp2) for stapling, the first group and the second group (gp1, gp2) being used in alternate one band out of two, so as to allow the realization of the cells (A). Thus, the first cycle provides stapling for the first group of positions (gp1) and the second cycle provides stapling for the second group of positions (gp2).

Comme illustré à la figure 2, pour tous les cycles postérieurs au premier cycle, le support (10) d'enclume doit être successivement inséré dans chacune des alvéoles (A) réalisées lors du cycle d'agrafage précédent pour permettre la fixation des agrafes (2) du cycle en cours. Naturellement, le reste de l'agrafeuse (1) est maintenu au-dessus de la bande (B) ajoutée pour chacun des nouveaux cycles. Une fois le support (10) inséré dans une alvéole (A) résultant du cycle précédant, deux alignements d'agrafes consécutifs vont être réalisés. Ensuite, le support (10) d'enclume ressort complètement sur le côté via un mouvement de translation approprié de l'agrafeuse et pourra s'insérer dans une autre alvéole (A) résultant du cycle précédent (les deux bandes supérieures étant soulevées).As illustrated in figure 2 for all cycles after the first cycle, the anvil support (10) must be successively inserted in each of the cells (A) made during the previous stapling cycle to allow the fixing of the staples (2) of the current cycle . Naturally, the rest of the stapler (1) is held above the strip (B) added for each of the new cycles. Once the support (10) inserted into a cell (A) resulting from the preceding cycle, two consecutive staple alignments will be made. Then, the anvil holder (10) is completely out of the way via the appropriate translation movement of the stapler and can be inserted into another cell (A) resulting from the previous cycle (the two upper bands being raised).

Dans l'exemple des figures 1 et 2, des alignements consécutifs peuvent être obtenus chacun de façon précise à l'aide d'un guidage du mouvement latéral de l'agrafeuse (1). Un maintien dans les positions (P1, P2) respectives correspondant à la direction d'alignement peut être réalisé à l'aide d'une tige (tg) solidaire de l'agrafeuse (1) et destinée à coopérer avec des moyens de guidage (6). En référence à la figure 1, le support (S) de bandes (B) est par exemple couplé à une pluralité de moyens de guidage (6) de l'agrafeuse (1) qui sont répartis le long du support de bandes (B) en fonction des positions souhaitées pour l'agrafage. Ces moyens de guidage (6) reçoivent la tige (tg), par engagement entre deux parois par exemple, et bloquent le mouvement longitudinal de l'agrafeuse (1). Des pairs de plaques, forment par exemple chacune un guide pour une position déterminée, les plaques étant, par exemple, de manière non limitative en bois, en métal, en plastique ou en thermoplastique, comme par exemple du polyméthacrylate de méthyle également désigné par PMMA. La tige (tg) qui est parallèle au support (10) d'enclume permet ainsi de guider l'agrafage des agrafes (2) d'une même série suivant la largeur (20). On est assuré d'obtenir une fixation de plusieurs agrafes (1) alignées entre elles pour une position déterminée (P1, P2).In the example of Figures 1 and 2 consecutive alignments can each be obtained accurately by means of a lateral movement guide of the stapler (1). A holding in the respective positions (P1, P2) corresponding to the alignment direction can be achieved by means of a rod (tg) integral with the stapler (1) and intended to cooperate with guiding means ( 6). With reference to the figure 1 the tape carrier (S) is for example coupled to a plurality of guide means (6) of the stapler (1) which are distributed along the tape carrier (B) according to the desired positions for stapling. These guide means (6) receive the rod (tg), by engagement between two walls for example, and block the longitudinal movement of the stapler (1). Peels of plates, for example each form a guide for a specific position, the plates being, for example, but not limited to wood, metal, plastic or thermoplastic, such as polymethyl methacrylate also designated by PMMA . The rod (tg) which is parallel to the anvil support (10) thus guides the stapling of the staples (2) of the same series along the width (20). It is ensured to obtain a fixation of several staples (1) aligned with each other for a given position (P1, P2).

L'agrafeuse (1) comprend un couteau mobile en translation (non représenté) permettant en association avec l'enclume (100), de fixer les agrafes (2). La position du couteau et l'orientation du chargeur (14) d'agrafes sont adaptées pour que les agrafes (2) soient chacune orientées suivant une orientation orthogonale à l'orientation générale du support (10) d'enclume. Le mouvement descendant du couteau permet l'insertion de l'agrafe (2) dans les deux bandes à fixer, tandis que l'enclume (100) permet de solliciter les extrémités d'agrafe et permet leur repliement sur la bande inférieure des bandes à fixer.The stapler (1) comprises a knife movable in translation (not shown) in association with the anvil (100), to fix the staples (2). The position of the knife and the orientation of the staple magazine (14) are adapted so that the staples (2) are each oriented in an orientation orthogonal to the general orientation of the anvil support (10). The downward movement of the knife allows the insertion of the staple (2) in the two strips to be fixed, while the anvil (100) makes it possible to solicit the staple ends and allows their folding on the lower band of the strips to be fixed.

On comprend que l'agrafeuse (1) vient agrafer en ligne des bandes (B) deux à deux sans requérir le moindre mouvement latéral pour les bandes (B), l'empilement restant toujours droit. L'espacement (E) entre le corps principal (11) de l'agrafeuse (1) et le support (10) d'enclume transversal permet en effet de ne pas modifier l'orientation générale en longueur des deux bandes (B) supérieures. Un décalage selon la longueur entre deux bandes successives est, par exemple, évité. C'est uniquement l'agrafeuse (1) qui se déplace latéralement une fois arrivée dans une position (P1, P2) d'agrafage. Dans l'exemple de la figure 1, la liaison (12) de l'agrafeuse (1) au bâti surélevé peut être équipée d'un ressort (r) ou moyen de rappel élastique analogue facilitant les opérations de soulèvement de l'agrafeuse (1) requises pour une bonne prise des bandes (B) à agrafer. Le soulèvement des bandes (B) pour permettre l'insertion du support (10) d'enclume peut être manuel ou réalisé par un outil complémentaire de levage d'une lame pouvant s'introduire sous les deux bandes (B) supérieures de l'empilement. Une plaque (15) peut être fixée sur le corps principal (11), par exemple sur le dessus, et permettre un raccordement par un bras ou une tige de manoeuvre descendante reliée au système mobile du bâti surélevé. Naturellement, un autre agencement peut convenir pour entraîner le déplacement de l'agrafeuse (1). Cette dernière peut alternativement être supportée latéralement par exemple et le bâti surélevé peut être remplacé par un rail au sol supportant le système mobile raccordé latéralement à l'agrafeuse (1).It is understood that the stapler (1) staple in line strips (B) in pairs without requiring the slightest lateral movement for the strips (B), the stack always remaining straight. The spacing (E) between the main body (11) of the stapler (1) and the transverse anvil support (10) makes it possible not to modify the general orientation in length of the two upper bands (B). . An offset along the length between two successive bands is, for example, avoided. Only the stapler (1) moves laterally when it reaches a stapling position (P1, P2). In the example of the figure 1 , the connection (12) of the stapler (1) to the elevated frame can be equipped with a spring (r) or similar elastic return means facilitating the lifting operations of the stapler (1) required for a good grip of the strips (B) to be stapled. The lifting of the strips (B) to allow the insertion of the anvil support (10) can be manual or performed by a complementary lifting tool of a blade that can be introduced under the two upper bands (B) of the stack. A plate (15) may be attached to the main body (11), for example on the top, and allow connection by an arm or a downward operating rod connected to the mobile system of the raised frame. Naturally, another arrangement may be suitable for causing the stapler (1) to move. The latter can alternatively be supported laterally for example and the raised frame can be replaced by a rail on the ground supporting the mobile system laterally connected to the stapler (1).

En référence à la figure 6, l'agrafeuse (1) peut être du type à piston actionneur, actionnée manuellement via une gâchette (g) et/ou de façon pneumatique. Un automate peut déclencher l'agrafage en synchronisation avec les mouvements du système déplaçant l'agrafeuse (1). Cet automate peut utiliser pour cela un programme de contrôle de l'agrafeuse, prenant en compte les déplacements du système mobile monté sur le bâti (non représenté) et des signaux indiquant des positions d'agrafage. Alternativement, la connexion pneumatique (31) et raccords associés (30, 32) peuvent être supprimés et l'opération d'agrafage peut être réalisée manuellement, à l'aide des moyens d'indication des groupes respectifs de positions souhaitées (gp1, gp2).With reference to the figure 6 , the stapler (1) may be of the actuator piston type, manually actuated via a trigger (g) and / or pneumatically. An automaton can trigger stapling in synchronization with the movements of the system moving the stapler (1). This controller can use for this a stapler control program, taking into account the movements of the mobile system mounted on the frame (not shown) and signals indicating stapling positions. Alternatively, the pneumatic connection (31) and associated connectors (30, 32) can be omitted and the stapling operation can be performed manually, using the means for indicating the respective groups of desired positions (gp1, gp2).

Le procédé de fabrication comprend plusieurs paires de cycles réalisées comme suit :

  • l'ajout d'une bande sur un empilement (ou début d'empilement) de bandes (B) pour démarrer le cycle ;
  • pose des agrafes (2) sur les deux bandes supérieures de l'empilement, pour un premier groupe de positions (gp1) d'agrafage ;
  • l'ajout d'une bande additionnelle sur l'empilement de bandes (B) pour démarrer le cycle suivant ;
  • pose des agrafes (2) sur les deux bandes supérieures de l'empilement, pour un second groupe de positions (gp2) d'agrafage (positions décalées par rapport à celles du premier groupe (gp1))
The manufacturing process comprises several pairs of cycles carried out as follows:
  • adding a tape on a stack (or beginning of stacking) of tapes (B) to start the cycle;
  • placing staples (2) on the two upper strips of the stack for a first group of stitching positions (gp1);
  • adding an additional band on the stack of strips (B) to start the next cycle;
  • placing staples (2) on the two upper bands of the stack, for a second group of positions (gp2) stapling (positions offset from those of the first group (gp1))

Comme illustré à la figure 1, l'obtention des positions (gp1, gp2) pour l'un ou l'autre type de cycle est permise par un premier ensemble et un second ensemble de moyens de guidage (6). Une paire de moyens de guidage est prévue pour l'obtention des positions (P1, P2) d'agrafage d'un cycle représentées sur la figure 2, tandis qu'une paire suivante de moyens de guidage est prévue pour l'obtention des positions d'agrafage d'un autre cycle. Lors d'un cycle déterminé, l'agrafeuse (1) va donc s'arrêter au niveau de deux dispositifs successifs des moyens de guidage (6) puis dépasser sans s'arrêter les deux dispositifs suivants des moyens de guidage. En effet ces deux derniers ne servent que pour le cycle suivant. Il y a donc une alternance de paires de dispositifs de guidage respectivement utilisables pour l'un ou l'autre des cycles. Autrement dit, ce premier ensemble et ce second ensemble de dispositifs de guidage (6) sont utilisés en alternance une bande sur deux pour permettre de positionner l'agrafeuse (1) à des niveaux en alignement d'agrafage qui sont décalés une bande sur deux, de façon à permettre la réalisation des alvéoles (A).As illustrated in figure 1 , obtaining positions (gp1, gp2) for one or the other type of cycle is permitted by a first set and a second set of guide means (6). A pair of guide means is provided for obtaining the staple positions (P1, P2) of a cycle represented on the figure 2 while a next pair of guide means is provided for obtaining the stapling positions of another cycle. During a determined cycle, the stapler (1) will therefore stop at two successive devices guide means (6) and then beyond without stopping the two following devices guide means. Indeed these last two are only used for the next cycle. There is therefore an alternation of pairs of guiding devices respectively usable for one or the other of the cycles. In other words, this first set and this second set of guiding devices (6) are used alternately every other band to enable the stapler (1) to be positioned at staggered alignment levels which are shifted one out of two stripes. , so as to allow the realization of the cells (A).

Un des avantages du produit est que la fixation entre les bandes est plus simple qu'avec des opérations de couture et conserve une très bonne tenue dans le temps, la rigidité de la structure étant conservée durablement (contrairement aux produits enduits de colle/résine). Le produit se présente, par exemple, sous la forme de rouleau avant d'être déployé, ce qui facilite notamment son stockage et son transport.One of the advantages of the product is that the fastening between the strips is simpler than with sewing operations and retains a very good held in time, the rigidity of the structure being maintained durably (unlike products coated glue / resin). The product is, for example, in the form of roll before being deployed, which facilitates in particular its storage and transport.

Il doit être évident, pour les personnes versées dans l'art, que la présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué.It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed.
