Description

DESCRIPTION DESCRIPTION
TITRE : DISPOSITIF D’APPLICATION D’UNE BANDETITLE: DEVICE FOR APPLYING A TAPE
Domaine technique de l’invention Technical field of the invention
La présente invention concerne un dispositif d’application d’une bande sur une jointure entre deux panneaux. The present invention relates to a device for applying a strip to a joint between two panels.
Lors de la construction d’un mur, des panneaux, par exemple des plaques de plâtres, peuvent être disposés alignés les uns à la suite des autres afin de former ledit mur. De tels panneaux présentent habituellement un bord aminci, correspondant à une réduction de l’épaisseur du panneau à un bord d’extrémité de celui-ci. Ainsi, le contact de deux bords amincis de deux panneaux forme une jointure. When constructing a wall, panels, for example plasterboard, can be arranged aligned one after the other in order to form said wall. Such panels usually have a thinned edge, corresponding to a reduction in the thickness of the panel at one end edge thereof. Thus, the contact of two thinned edges of two panels forms a joint.
Une telle jointure nécessite d’être recouverte afin que celle-ci ne soit pas visible une fois la construction du mur finalisée. Le recouvrement d’une telle jointure revête entre autres d’un aspect d’étanchéité du mur et d’un aspect esthétique. Ainsi, il est courant d’utiliser des bandes par exemple de papier, afin de recouvrir les jointures des panneaux. Such a joint needs to be covered so that it is not visible once the construction of the wall is finalized. The covering of such a joint has, among other things, a waterproofing aspect of the wall and an aesthetic aspect. Thus, it is common to use strips, for example of paper, to cover the joints of the panels.
L’installation des bandes en jointure de panneaux consiste notamment en une étape de garnissage de la jointure par un enduit, puis une étape au cours de laquelle on dispose la bande sur l’enduit frais, puis une étape de serrage de bande, c’est-à-dire une étape au cours de laquelle la bande est plaquée contre l’enduit frais afin de chasser l’air et l’excèdent d’enduit sous celle-ci, puis une étape de récupération de l’excédent d’enduit. Par la suite la bande est de nouveau recouverte du même enduit qu’il faudra lisser. The installation of the strips at the panel joints consists in particular of a step of filling the joint with a coating, then a step during which the strip is placed on the fresh coating, then a step of tightening the strip, this that is to say a step during which the strip is pressed against the fresh coating in order to expel the air and the excess coating under it, then a step of recovering the excess coating . Subsequently, the strip is again covered with the same coating which must be smoothed.
Lors de la pose de la bande il est nécessaire de s’assurer que la bande est convenablement plaquée sur l’enduit tout en débarrassant la jointure et les panneaux de l’excédent d’enduit pouvant créer des irrégularités sur le mur une fois fini. Ces étapes sont fastidieuses et nécessitent de nombreuses opérations et manipulations de la part d’un opérateur. Également, ces étapes nécessitent de nombreux outils et leur utilisation sur des panneaux d’une hauteur importante peut s’avérer complexe. When installing the strip it is necessary to ensure that the strip is properly placed on the coating while clearing the joint and the panels of excess coating which could create irregularities on the wall once finished. These steps are tedious and require numerous operations and manipulations on the part of an operator. Also, these steps require numerous tools and their use on high panels can be complex.
Ainsi, l’invention se propose de résoudre le problème susmentionné en permettant de simplifier la pose de la bande en jointure de panneaux de plâtre. Notamment, l’invention propose un dispositif permettant de réaliser l’étape de serrage de la bande et de raclage du surplus d’enduit de manière simultanée et avec un unique dispositif. Thus, the invention proposes to solve the aforementioned problem by making it possible to simplify the installation of the strip at the joints of panels of plaster. In particular, the invention proposes a device making it possible to carry out the step of tightening the strip and scraping off the excess coating simultaneously and with a single device.

Description détaillée de l'invention Detailed description of the invention
Pour la description de l'invention et la compréhension des revendications, on adoptera à titre non limitatif et sans référence limitative à la gravité terrestre les orientations verticale, longitudinale et transversale selon le repère V, L, T indiqué aux figures dont les axes longitudinal L et transversal T s’étendent dans un plan horizontal. Par convention, l’axe longitudinal L est orienté de l’arrière vers l’avant. For the description of the invention and the understanding of the claims, we will adopt on a non-limiting basis and without limiting reference to terrestrial gravity the vertical, longitudinal and transverse orientations according to the reference V, L, T indicated in the figures whose longitudinal axes L and transverse T extend in a horizontal plane. By convention, the longitudinal axis L is oriented from rear to front.
Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence. In the description which follows, identical, similar or analogous elements will be designated by the same reference numerals.
La figure 1 illustre un ensemble d’application 10 d’une bande 12 sur une jointure 14 entre deux panneaux 16, par exemple d’un mur. Les deux panneaux 16 peuvent être par exemple et de manière non limitative des plaques de plâtre utilisées de manière habituelle dans les constructions de bâtiments et peuvent, par exemple et de manière non limitative, présenter un bord 17 aminci. On entend par bords 17 amincis une réduction de l'épaisseur des panneaux 16. Ainsi, la jointure 14 entre les deux panneaux 16 correspond au contact du bord 17, par exemple aminci, de chacun des panneaux 16. On comprend alors que les bords amincis forment une rainure entre les deux panneaux 16 correspondant à la jointure 14. Figure 1 illustrates an application assembly 10 of a strip 12 on a joint 14 between two panels 16, for example of a wall. The two panels 16 can be, for example and in a non-limiting manner, plasterboards usually used in building construction and can, for example and in a non-limiting manner, have a thinned edge 17. By thinned edges 17 we mean a reduction in the thickness of the panels 16. Thus, the joint 14 between the two panels 16 corresponds to the contact of the edge 17, for example thinned, of each of the panels 16. It is then understood that the thinned edges form a groove between the two panels 16 corresponding to the joint 14.
Une telle jointure 14 entre les deux panneaux 16 nécessite d’être recouverte pour former une zone lisse et continue. Ainsi, il est habituel de disposer la bande 12, par exemple de papier, en recouvrement de la jointure 14. Pour ce faire, un enduit permettant de coller la bande 12 est utilisé. Such a joint 14 between the two panels 16 needs to be covered to form a smooth and continuous zone. Thus, it is usual to arrange the strip 12, for example of paper, covering the joint 14. To do this, a coating allowing the strip 12 to be glued is used.
Le procédé d’application de la bande 12 sera détaillé plus loin dans la suite de la description détaillée. The process of applying strip 12 will be detailed later in the detailed description.
Afin d’appliquer la bande 12 en recouvrement de la jointure 14, l’ensemble d’application 10 selon l’exemple de l’invention illustré peut être avantageusement utilisé. In order to apply the strip 12 to cover the joint 14, the application assembly 10 according to the example of the invention illustrated can be advantageously used.
L’ensemble d’application 10 comprend alors au moins un dispositif 18 d’application et un support 20 configuré pour être fixé à un réservoir 22 d’un élément de collage, par exemple un réservoir 22 pour l’enduit, évoqué précédemment. The application assembly 10 then comprises at least one application device 18 and a support 20 configured to be fixed to a reservoir 22 of a bonding element, for example a reservoir 22 for the coating, mentioned previously.
Le dispositif 18 d’application, particulièrement visible aux figures 2 à 5, comprend au moins une platine 24 qui s’étend dans un plan principal P longitudinal L et transversal T et qui forme un corps principal du dispositif 18 d’application. On comprend donc que la platine 24 forme une surface plane dont on définit un premier coté 26 et un deuxième coté 28 opposés l’un de l’autre suivant une direction verticale V. The application device 18, particularly visible in Figures 2 to 5, comprises at least one plate 24 which extends in a main plane P longitudinal L and transverse T and which forms a main body of the device 18 application. We therefore understand that the plate 24 forms a flat surface of which we define a first side 26 and a second side 28 opposite each other in a vertical direction V.
Dans la suite de la description on définira le premier coté 26 comme étant le coté destiné à être en regard de la bande lors de l’utilisation du dispositif 18 d’application et le deuxième coté 28 comme étant le coté destiné à être opposé à la bande, c’est-à-dire tourné vers un opérateur du dispositif 18 d’application. In the remainder of the description we will define the first side 26 as being the side intended to be opposite the strip when using the application device 18 and the second side 28 as being the side intended to be opposite the strip, that is to say turned towards an operator of the application device 18.
Le dispositif 18 d’application selon l’exemple de l’invention illustré comprend au moins un rouleau 30 et un organe de raclage 32. The application device 18 according to the example of the invention illustrated comprises at least one roller 30 and a scraping member 32.
De manière plus précise, la platine 24 comprend au moins une première lumière 34 et une deuxième lumière 36. On entend par lumière une ouverture traversante dans une épaisseur de la platine. La première lumière 34 et la deuxième lumière 36 présentent une forme sensiblement d’un quadrilatère. More precisely, the plate 24 comprises at least a first light 34 and a second light 36. By light we mean a through opening in a thickness of the plate. The first light 34 and the second light 36 have a shape substantially of a quadrilateral.
En définissant deux parties égales de la platine 24, c’est-à-dire miroir l’une de l’autre, suivant un plan sécant S transversal T et vertical V, la première lumière 34 et la deuxième lumière 36 sont formées dans la platine 24, dans une même partie de celle-ci, nommée alors première partie 38 de la platine 24. By defining two equal parts of the plate 24, that is to say mirror of one another, along a transverse plane S transverse T and vertical V, the first light 34 and the second light 36 are formed in the plate 24, in the same part thereof, then called first part 38 of plate 24.
Dans la suite de la description, un mode de réalisation avantageux va être décrit dans lequel la forme particulière de la platine est réalisée par découpage et pliage d’une pièce de tôle. Ce mode de réalisation permet avantageusement d’obtenir une platine à la solidité optimale puisque faite d’un seul tenant. In the remainder of the description, an advantageous embodiment will be described in which the particular shape of the plate is produced by cutting and folding a piece of sheet metal. This embodiment advantageously makes it possible to obtain a plate with optimal solidity since it is made in one piece.
On comprend par ailleurs que ce mode de réalisation avantageux n’est pas limitatif et que la platine peut être réalisée par tout autre moyen, par exemple par moulage. It is also understood that this advantageous embodiment is not limiting and that the plate can be produced by any other means, for example by molding.
Tel que visible à la figure 2, la première lumière 34 est formée par un découpage de la platine 24 de telle sorte à former une languette 40 rectangulaire, visible à la figure 3, puis par déformation de ladite languette 40. Dit autrement, la platine 24 est découpée de telle sorte à former trois bords intérieurs 42 en forme de U et une languette 40 résultant du découpage des trois bords intérieurs 42. As visible in Figure 2, the first light 34 is formed by cutting the plate 24 so as to form a rectangular tongue 40, visible in Figure 3, then by deformation of said tongue 40. In other words, the plate 24 is cut in such a way as to form three U-shaped interior edges 42 and a tongue 40 resulting from the cutting of the three interior edges 42.
La languette 40 de forme sensiblement rectangulaire est par la suite déformée de telle sorte qu’elle s’étende dans un plan sécant du plan principal P de la platine 24 et au travers de la première lumière 38. The tongue 40 of substantially rectangular shape is subsequently deformed such that it extends in a intersecting plane of the main plane P of the plate 24 and through the first light 38.
On comprend alors que la languette 40 est solidaire de la platine 24 par un bord de liaison 44 qui s’étend transversalement sur la platine 24 et opposé longitudinalement à un des bords intérieurs 42 de la première lumière 34 qui s’étend transversalement. We then understand that the tongue 40 is secured to the plate 24 by a connecting edge 44 which extends transversely on the plate 24 and opposite longitudinally to one of the interior edges 42 of the first light 34 which extends transversely.
L’organe de raclage 32 comprend au moins une lame 46 qui s’étend dans un plan sécant du plan principal P de la platine 24. La lame 46 comprend notamment un bord de fixation 48, visible à la figure 3, et un bord d'extrémité transversal 50, opposés l’un de l’autre suivant une direction d’allongement principal de la lame 46. Le bord de fixation 48 de la lame 46 correspond notamment au bord de la lame 46 solidaire de la languette 40 évoquée ci-dessus. The scraping member 32 comprises at least one blade 46 which extends in a intersecting plane of the main plane P of the plate 24. The blade 46 comprises in particular a fixing edge 48, visible in Figure 3, and an edge d transverse end 50, opposite each other in a direction of main elongation of the blade 46. The fixing edge 48 of the blade 46 corresponds in particular to the edge of the blade 46 secured to the tongue 40 mentioned above.
Selon un exemple non limitatif de l’invention, le bord de fixation 48 de la lame 46 et la languette 40 peuvent être solidaires l’un de l'autre par vissage, rivetage ou clipsage. According to a non-limiting example of the invention, the fixing edge 48 of the blade 46 and the tongue 40 can be secured to one another by screwing, riveting or clipping.
La lame 46 s’étend ainsi dans un plan commun avec la languette 40 et vers un sens opposé longitudinalement à la deuxième lumière 36, c’est-à- dire de telle sorte à s’étendre en regard d’une deuxième partie 52 de la platine 24, opposée longitudinalement à la première partie 38 de la platine 24 évoquée précédemment. The blade 46 thus extends in a common plane with the tongue 40 and towards a direction opposite longitudinally to the second light 36, that is to say in such a way as to extend facing a second part 52 of the plate 24, opposite longitudinally to the first part 38 of the plate 24 mentioned above.
L’organe de raclage 32 s’étend par ailleurs en regard, au moins en partie, du premier côté 26 de la platine 24. The scraping member 32 also extends facing, at least in part, the first side 26 of the plate 24.
On comprend alors que le bord d’extrémité transversal 50 de la lame 46 est destiné à venir au contact de la bande lors de l’utilisation du dispositif 18 d’application. It is then understood that the transverse end edge 50 of the blade 46 is intended to come into contact with the strip when using the application device 18.
Selon une caractéristique non limitative de l’invention, le bord d’extrémité transversal 50 de la lame 46 s’étend sur une première dimension transversale DT1 visible à la figure 4 et comprise entre 100mm et 150mm. Selon un exemple avantageux, la première dimension transversale DT1 est égale à 125mm. According to a non-limiting characteristic of the invention, the transverse end edge 50 of the blade 46 extends over a first transverse dimension DT1 visible in Figure 4 and between 100mm and 150mm. According to an advantageous example, the first transverse dimension DT1 is equal to 125mm.
L’organe de raclage 32 comprend par ailleurs au moins deux ailes 54 qui s’étendent de part et d’autre de la lame 46 selon la direction transversale T, depuis son bord d’extrémité transversal 50 et de telle sorte que les ailes 54 s’étendent dans un plan sécant du plan principal P de la platine 24 et du plan de la lame 46 de l'organe de raclage 32. Les ailes 54 s’étendent notamment vers le rouleau 30. The scraping member 32 further comprises at least two wings 54 which extend on either side of the blade 46 in the transverse direction T, from its transverse end edge 50 and such that the wings 54 extend in a plane intersecting the main plane P of the plate 24 and the plane of the blade 46 of the scraping member 32. The wings 54 extend in particular towards the roller 30.
Ainsi, lors de l’utilisation du dispositif 18 d’application, le bord d’extrémité transversal 50 de la lame 46 est destiné à retirer l’excédent d’enduit sur et autour de la bande et les ailes 54 qu’ils portent permettent de canaliser l’enduit afin de faciliter sa récupération. Thus, when using the application device 18, the transverse end edge 50 of the blade 46 is intended to remove the excess coating on and around the strip and the wings 54 which they carry allow to channel the coating in order to facilitate its recovery.
Selon un exemple de l'invention, au moins le bord de fixation 48 de la lame 46 est déformable élastiquement. On entend par déformable élastiquement le fait que le bord de fixation 48 est capable de se déformer et de revenir à son état initial non déformé sans rupture de sa matière. On comprend alors qu’une telle caractéristique permet à la lame 46 d’être plus souple lors de l’utilisation du dispositif 18 d’application et de résister à une pression exercée par un opérateur dans l’objectif de plaquer le bord d’extrémité transversale 50 contre la bande. According to an example of the invention, at least the fixing edge 48 of the blade 46 is elastically deformable. By elastically deformable we mean the fact that the fixing edge 48 is capable of deforming and returning to its initial non-deformed state without breaking its material. We then understand that such a characteristic allows the blade 46 to be more flexible when using the application device 18 and to resist pressure exerted by an operator with the aim of pressing the end edge transversal 50 against the strip.
On comprend par ailleurs que la déformation élastique du bord de fixation 48 de la lame 46 déplace cette dernière vers le premier coté 26 de la platine 24 de telle sorte à réduire un espace vertical qui les sépare. It is also understood that the elastic deformation of the fixing edge 48 of the blade 46 moves the latter towards the first side 26 of the plate 24 so as to reduce a vertical space which separates them.
De ce fait, selon un exemple de l’invention, le dispositif 18 d’application comprend au moins un organe de butée 56 qui s’étend depuis la platine 24 vers la lame 46 de l’organe de raclage 32. Therefore, according to an example of the invention, the application device 18 comprises at least one stop member 56 which extends from the plate 24 towards the blade 46 of the scraping member 32.
De manière plus précise, l’organe de butée 56 peut prendre la forme d’une vis 56a traversant verticalement un orifice formé dans la platine 24 et bloquée en position par deux écrous 56b disposés de part et d’autre de la platine 24 selon la direction verticale V. On comprend alors que l’organe de butée 56 selon l’exemple de l’invention s’étend sur le premier coté 26 et sur le deuxième côté 28 de la platine 24. More precisely, the stop member 56 can take the form of a screw 56a passing vertically through an orifice formed in the plate 24 and locked in position by two nuts 56b arranged on either side of the plate 24 according to the vertical direction V. It is then understood that the stop member 56 according to the example of the invention extends over the first side 26 and over the second side 28 of the plate 24.
L’organe de butée 56 comprend alors un élément d’amortissement 56c disposé à une extrémité de la vis 56a qui s’étend sur le premier côté 26 de la platine 24, en regard de la lame 46 de l’organe de raclage 32. The stop member 56 then comprises a damping element 56c disposed at one end of the screw 56a which extends on the first side 26 of the plate 24, facing the blade 46 of the scraping member 32.
L’élément d’amortissement 56c peut être par exemple et de manière non limitative un ergot en une matière souple tel que du caoutchouc. The damping element 56c can be for example and in a non-limiting manner a lug made of a flexible material such as rubber.
L’organe de butée 56 est par ailleurs disposé dans la deuxième partie 52 de la platine 24 de telle sorte à s’étendre en regard de la lame 46 de l’organe de raclage 32. The stop member 56 is also arranged in the second part 52 of the plate 24 so as to extend opposite the blade 46 of the scraping member 32.
On comprend alors que l’organe de butée 56 tel que décrit, peut-être déplacé verticalement au travers de l’orifice de la platine 24, et que les écrous 56b assurent le maintien en position de la vis 56a au travers de l’orifice. We then understand that the stop member 56 as described can be moved vertically through the orifice of the plate 24, and that the nuts 56b ensure that the screw 56a is held in position through the orifice. .
Selon un exemple avantageux de l’invention, le dispositif 18 d’application comprend deux organes de butées 56 selon les caractéristiques ci-dessus, les organes de butées 56 étant alignés le long d’une droite transversale T. According to an advantageous example of the invention, the application device 18 comprises two stop members 56 according to the above characteristics, the stop members 56 being aligned along a transverse line T.
Ainsi, on tire avantage de tels organes de butées 56 formés chacun par une vis 56a et deux écrous 56b, en ce qu’ils peuvent être ajustés verticalement. Ainsi, les organes de butées 56 forment un appui de la lame 46 de l’organe de raclage 32 lors de la déformation du bord de fixation 48 pendant l’utilisation du dispositif 18 d’application et assurent ainsi la stabilité du bord d’extrémité transversal 50 de la lame 46 lors de son passage au moins sur la bande. Thus, we take advantage of such stop members 56 each formed by a screw 56a and two nuts 56b, in that they can be adjusted vertically. Thus, the stop members 56 form a support for the blade 46 of the scraping member 32 during the deformation of the fixing edge 48 during the use of the application device 18 and thus ensure the stability of the end edge transverse 50 of the blade 46 during its passage at least on the strip.
Dit autrement, les deux organes de butées 56 tels qu’ils viennent d’être décrits, limitent la déformation transversale et verticale de la lame 46 lors de l’utilisation du dispositif 18 d’application afin que le bord d’extrémité transversale 50 soit continuellement au contact au moins de la bande, sur toute sa surface. Les deux organes de butées 56 permettent par ailleurs l’alignement parallèle de l’aile 54 avec le panneau 16. On améliore ainsi le raclage de l’enduit. In other words, the two stop members 56 as they have just been described, limit the transverse and vertical deformation of the blade 46 when using the application device 18 so that the transverse end edge 50 is continuously in contact with at least the strip, over its entire surface. The two stop members 56 also allow the parallel alignment of the wing 54 with the panel 16. This improves the scraping of the coating.
La deuxième lumière 36 de la platine 24 est formée de telle sorte que la première lumière 34 s’étend longitudinalement entre la deuxième lumière 36 et la deuxième partie 52 de la platine 24. The second light 36 of the plate 24 is formed such that the first light 34 extends longitudinally between the second light 36 and the second part 52 of the plate 24.
La deuxième lumière 38 est formée par découpage de la platine 24 le long de deux droites parallèles à la direction transversale T, de telle sorte à former deux arêtes internes 58 de la deuxième lumière 38. Par la suite, la portion de la platine 24 s’étendant entre les deux arêtes internes 58 et découpée longitudinalement de telle sorte à former deux pattes de fixation 60. The second light 38 is formed by cutting the plate 24 along two straight lines parallel to the transverse direction T, so as to form two internal edges 58 of the second light 38. Subsequently, the portion of the plate 24 s extending between the two internal edges 58 and cut longitudinally so as to form two fixing lugs 60.
De manière plus précise, les pattes de fixation 60 sont pliées au niveau d’un bord de liaison longitudinal 62 avec la platine 24 afin de s’étendre chacune dans un plan longitudinal L et vertical V, formant ainsi la deuxième lumière 36 de la platine 24. More precisely, the fixing lugs 60 are folded at a longitudinal connecting edge 62 with the plate 24 in order to each extend in a longitudinal plane L and vertical V, thus forming the second light 36 of the plate 24.
Les pattes de fixation 60 s’étendent par ailleurs vers le premier côté 26 de la platine 24. The fixing lugs 60 also extend towards the first side 26 of the plate 24.
On comprend alors que la deuxième lumière 36 est formée par les deux arêtes internes 58 qui s’étendent transversalement en regard l’une de l’autre, et par les deux bords de liaison longitudinal 62 des pattes de fixation 60, lesdits bords de liaison longitudinal 62 reliant longitudinalement les arêtes internes 58 l’une à l’autre. We then understand that the second light 36 is formed by the two internal edges 58 which extend transversely facing each other, and by the two longitudinal connecting edges 62 of the fixing lugs 60, said connecting edges longitudinal 62 longitudinally connecting the internal edges 58 to each other.
Tel que particulièrement visible à la figure 2, le rouleau 30 s’étend en regard de la deuxième lumière 36 de la platine 24. Plus particulièrement, le rouleau 30 est solidaire de la platine 24 via des moyens de fixation 64 autorisant la rotation du rouleau 30 autour d’un axe de rotation R transversal T. As particularly visible in Figure 2, the roller 30 extends opposite the second light 36 of the plate 24. More particularly, the roller 30 is secured to the plate 24 via fixing means 64 authorizing the rotation of the roller 30 around a transverse axis of rotation R T.
Selon l’exemple de l’invention illustré, les moyens de fixation 64 peuvent comprendre les pattes de fixation 60 évoquées ci-dessus et qui comprennent chacune une ouverture circulaire 66 configurée pour recevoir l’axe de rotation R du rouleau 30, non visible. According to the example of the invention illustrated, the fixing means 64 can comprise the fixing lugs 60 mentioned above and which each include a circular opening 66 configured to receive the axis of rotation R of the roller 30, not visible.
L’axe de rotation R du rouleau 30 peut être par exemple un arbre traversant le rouleau et logeant dans les ouvertures circulaires des pattes de fixation ou peut prendre la forme de deux ergots cylindriques qui s’étendent en saillie des extrémités libres transversales du rouleau de telle sorte à loger dans les ouvertures circulaires. The axis of rotation R of the roller 30 can for example be a shaft passing through the roller and housed in the circular openings of the fixing lugs or can take the form of two cylindrical lugs which extend projecting from the transverse free ends of the roller. so as to fit into the circular openings.
On comprend par ailleurs que le rouleau 30 et l’organe de raclage 32 s’étendent d’un même côté de la platine 24, ici le premier coté 26. We also understand that the roller 30 and the scraping member 32 extend on the same side of the plate 24, here the first side 26.
Le rouleau 30 tel que visible à la figure 4, présente une forme de double cônes de révolution 68 dont des bases 70 sont intégralement en contact l’une de l’autre. The roller 30 as visible in Figure 4, has the shape of double cones of revolution 68 whose bases 70 are fully in contact with each other.
En d’autres termes, le rouleau 30 présente une forme cylindrique dont un diamètre D décroit depuis un centre C du cylindre, pris dans un plan longitudinal L et vertical V et formé par les bases 70 des deux cônes de révolution 68, vers les extrémités libres transversales 72 dudit rouleau 30. In other words, the roller 30 has a cylindrical shape whose diameter D decreases from a center C of the cylinder, taken in a longitudinal plane L and vertical V and formed by the bases 70 of the two cones of revolution 68, towards the ends transverse free parts 72 of said roller 30.
Dit encore autrement, on définit le centre C du rouleau 30 dans un plan vertical V et longitudinal L, pris à équidistance des extrémités libres transversales 72 du rouleau 30. Said another way, we define the center C of the roller 30 in a vertical V and longitudinal plane L, taken equidistant from the transverse free ends 72 of the roller 30.
Le centre C représente alors la partie du rouleau 30 dont le diamètre D est le plus important et les extrémités libres transversales 72 représentent les parties du rouleau 30 dont le diamètre D est le moins important. The center C then represents the part of the roller 30 whose diameter D is the largest and the free transverse ends 72 represent the parts of the roller 30 whose diameter D is the least important.
Selon une caractéristique non limitative de l’invention, le rouleau 30 présente un degré d’inclinaison I entre son centre C et ses extrémités libres transversales 72, compris entre 1 ° et 5°. Selon un exemple avantageux, le degré d’inclinaison I est de 2°. According to a non-limiting characteristic of the invention, the roller 30 has a degree of inclination I between its center C and its transverse free ends 72, between 1° and 5°. According to an advantageous example, the degree of inclination I is 2°.
Une telle configuration du rouleau 30 est avantageuse en ce qu’elle permet, lors de l’utilisation du dispositif 18 d’application, de diriger l’enduit excédent vers la périphérie extérieure de la bande afin qu’il puisse par la suite être raclé par l’organe de raclage 32. Such a configuration of the roller 30 is advantageous in that it allows, when using the application device 18, to direct the coating excess towards the outer periphery of the strip so that it can subsequently be scraped by the scraping member 32.
Tel que visible aux figures 3 et 4, le rouleau 30 comprend une zone de contact linéique LIN destinée à venir en appui au moins contre la bande. As visible in Figures 3 and 4, the roller 30 comprises a linear contact zone LIN intended to come to bear at least against the strip.
Ainsi, au moins la zone de contact linéique LIN située au centre C du rouleau 30 et le bord d’extrémité transversal 50 s’étendent dans un plan longitudinal L et transversal T commun. Thus, at least the linear contact zone LIN located at the center C of the roller 30 and the transverse end edge 50 extend in a common longitudinal L and transverse plane T.
Une telle caractéristique permet de garantir un contact entre la bande et d’une part le rouleau 30 et d’autre part le bord d’extrémité transversal 50 du dispositif 18 d’application. Such a characteristic makes it possible to guarantee contact between the strip and on the one hand the roller 30 and on the other hand the transverse end edge 50 of the application device 18.
Selon un exemple de l’invention visible à la figure 4, on définit une deuxième dimension transversale DT2 du rouleau 30 prise le long de son axe de rotation R. La première dimension transversale DT1 du bord d’extrémité transversal 50 de la lame 46 est alors supérieure à la deuxième dimension transversale DT2 du rouleau 30. According to an example of the invention visible in Figure 4, we define a second transverse dimension DT2 of the roller 30 taken along its axis of rotation R. The first transverse dimension DT1 of the transverse end edge 50 of the blade 46 is then greater than the second transverse dimension DT2 of the roller 30.
On comprend qu’une telle caractéristique permet au bord d’extrémité transversal 50 de la lame 46 d’assurer une récupération optimale de l’enduit chassé en périphérie de la bande par le rouleau 30 préalablement au passage de la lame 46. It is understood that such a characteristic allows the transverse end edge 50 of the blade 46 to ensure optimal recovery of the coating driven from the periphery of the strip by the roller 30 prior to the passage of the blade 46.
Selon un exemple non limitatif de l’invention, la deuxième dimension transversale DT2 du rouleau 30 est comprise entre 85mm et 95mm. Selon un exemple avantageux, la deuxième dimension transversale DT2 est égale à 90mm. According to a non-limiting example of the invention, the second transverse dimension DT2 of the roller 30 is between 85mm and 95mm. According to an advantageous example, the second transverse dimension DT2 is equal to 90mm.
Tel que visible à la figure 4, la lame 46 de l’organe de raclage 32 présente une dimension transversale croissante depuis son bord de fixation vers son bord d’extrémité transversal 50. On comprend alors que la lame 46 présente une forme évasée depuis son bord de fixation vers son bord d’extrémité transversal 50. As visible in Figure 4, the blade 46 of the scraping member 32 has an increasing transverse dimension from its fixing edge towards its transverse end edge 50. It is then understood that the blade 46 has a flared shape from its fixing edge towards its transverse end edge 50.
Une telle caractéristique permet de conserver une dimension optimale du bord d’extrémité transversal 50 de la lame 46 tel que décrit ci-dessus, tout en limitant une dimension transversale de la languette 40, et ainsi de la première lumière 34. On garantit ainsi un raclage optimal de l'enduit et une solidité optimale de la platine 24. Le dispositif d’application 18 visible à la figure 5 est par ailleurs configuré pour coopérer avec un ensemble comprenant un manche 76 couplé à un plateau 74. On comprend ainsi que le plateau 74 et le manche 76 forment une seule et même pièce. Such a characteristic makes it possible to maintain an optimal dimension of the transverse end edge 50 of the blade 46 as described above, while limiting a transverse dimension of the tongue 40, and thus of the first light 34. This guarantees a optimal scraping of the coating and optimal solidity of the plate 24. The application device 18 visible in Figure 5 is also configured to cooperate with an assembly comprising a handle 76 coupled to a plate 74. It is thus understood that the plate 74 and the handle 76 form one and the same part.
Plus précisément, le plateau 74 est disposé principalement sur le centre de la platine 24, à cheval entre la première partie 38 et la deuxième partie 52 de la platine 24, et s’étend sur le deuxième coté 28 de telle sorte à recouvrir au moins en partie la première lumière 34 de la platine 24. More precisely, the plate 74 is arranged mainly on the center of the plate 24, straddling between the first part 38 and the second part 52 of the plate 24, and extends on the second side 28 so as to cover at least partly the first light 34 of the plate 24.
Le plateau 74 est alors solidaire de la platine 24 par un système de fixation composé de deux vis avec écrous, par exemple de type papillons. On comprend alors que des trous sont formés dans la platine 24 afin de recevoir les vis et écrous du système de fixation du plateau 74. Ainsi, la solidarisation du plateau 74 sur la platine 24 s’opère par coopération dudit plateau 74 avec le système de fixation comprenant les deux vis avec écrous. La coopération entre le plateau et le système de fixation correspond par exemple à un encliquetage du plateau sur ce dernier. De préférence les trous sur la platine sont espacés de 110mm selon la direction transversale T. The plate 74 is then secured to the plate 24 by a fixing system composed of two screws with nuts, for example of the butterfly type. It is then understood that holes are formed in the plate 24 in order to receive the screws and nuts of the fixing system of the plate 74. Thus, the securing of the plate 74 on the plate 24 takes place by cooperation of said plate 74 with the system of fixing including two screws with nuts. The cooperation between the plate and the fixing system corresponds for example to a snapping of the plate onto the latter. Preferably the holes on the plate are spaced 110mm apart in the transverse direction T.
Un tel ensemble comprenant le manche 76 et le plateau 74 dit « manche boite de finition » est par ailleurs connu de l’état de la technique et correspond à un élément de fixation standard sur le marché. Such an assembly comprising the handle 76 and the plate 74 called “finishing box handle” is also known from the state of the art and corresponds to a standard fixing element on the market.
On tire alors avantage d’une telle caractéristique en ce qu’elle permet une utilisation du dispositif d’application 18 dans un sens ou dans l’autre. Un tel avantage de l’invention sera exposé plus en détail lors de la description du procédé d’utilisation de l’ensemble d’application. We then take advantage of such a characteristic in that it allows use of the application device 18 in one direction or the other. Such an advantage of the invention will be explained in more detail during the description of the method of using the application assembly.
La platine 24 selon l’exemple de l’invention illustré comprend par ailleurs une découpe avant 77 qui s’étend transversalement dans la première partie 38 de la platine 24 et plus particulièrement le long d’une arrête d’extrémité transversale de la platine 24. Une telle découpe avant 77 est notamment centrée sur la platine 24 selon la direction transversale T. The plate 24 according to the illustrated example of the invention also comprises a front cutout 77 which extends transversely in the first part 38 of the plate 24 and more particularly along a transverse end edge of the plate 24 Such a front cutout 77 is in particular centered on the plate 24 in the transverse direction T.
Ainsi, une telle découpe avant 77 forme un moyen de guidage pour un utilisateur de l’ensemble d’application permettant de faciliter le déplacement du dispositif 18 d’application le long de la bande. Thus, such a front cutout 77 forms a guiding means for a user of the application assembly making it possible to facilitate movement of the application device 18 along the strip.
La découpe avant 77 présente par ailleurs une dimension transversale comprise entre 40mm et 60mm. De préférence, la découpe avant 71 s’étend sur une dimension transversale de 50mm correspondant habituellement à une dimension transversale, ou largeur, de la bande. The front cutout 77 also has a transverse dimension of between 40mm and 60mm. Preferably, the front cutout 71 extends over a transverse dimension of 50mm usually corresponding to a transverse dimension, or width, of the strip.
L’ensemble d’application 10 comprend également le support 20 évoqué précédemment. The application assembly 10 also includes the support 20 mentioned previously.
Dans la suite de la description, on comprendra que les directions longitudinale L, transversale T et verticale V du support 20 correspondent à celles du dispositif 18 d’application lors de l’utilisation du support 20 avec le dispositif 18 d’application. In the remainder of the description, it will be understood that the longitudinal L, transverse T and vertical V directions of the support 20 correspond to those of the application device 18 when using the support 20 with the application device 18.
Le support 20 particulièrement visible à la figure 6, comprend au moins une surface de guidage 78 configurée pour recevoir et guider le rouleau du dispositif d’application en rotation, et comprend une paroi de raclage 80 configurée pour recevoir la lame de l’organe de raclage lorsque le rouleau est guidé par la surface de guidage. The support 20, particularly visible in Figure 6, comprises at least one guide surface 78 configured to receive and guide the roller of the application device in rotation, and comprises a scraping wall 80 configured to receive the blade of the application member. scraping when the roller is guided by the guide surface.
Plus particulièrement, on définit une partie centrale 82 du support 20, la surface de guidage 78 s’étendant longitudinalement depuis la partie centrale 82 jusqu’à un bord libre 84 de la surface de guidage 78. More particularly, a central part 82 of the support 20 is defined, the guide surface 78 extending longitudinally from the central part 82 to a free edge 84 of the guide surface 78.
La surface de guidage 78 s’étend sur une troisième distance transversale DT3 qui est supérieure à la deuxième dimension transversale DT2 du rouleau 30 évoquée précédemment. The guide surface 78 extends over a third transverse distance DT3 which is greater than the second transverse dimension DT2 of the roller 30 mentioned previously.
Plus particulièrement, la surface de guidage 78 présente une forme évasée de telle sorte que sa troisième distance transversale DT3 soit supérieure au niveau de la partie centrale 82 par rapport à son bord libre 84. More particularly, the guide surface 78 has a flared shape such that its third transverse distance DT3 is greater at the level of the central part 82 relative to its free edge 84.
Une telle caractéristique permet alors de faciliter le positionnement du rouleau sur la surface de guidage 78 au niveau de la partie centrale 82, lors de l’utilisation du support 20. Such a characteristic then makes it possible to facilitate the positioning of the roller on the guide surface 78 at the level of the central part 82, when using the support 20.
Le surface de guidage 78 du support 20 comprend par ailleurs des bordures relevées 86 qui s’étendent suivant la direction longitudinale L et en périphérie transversale T de celle-ci. De telles bordures relevées 86 participent au guidage et au maintien transversal du rouleau le long de la surface de guidage 78. The guide surface 78 of the support 20 also comprises raised edges 86 which extend in the longitudinal direction L and at the transverse periphery T thereof. Such raised edges 86 participate in guiding and transversely maintaining the roller along the guide surface 78.
Les bordures relevées 86 de la surface de guidage 78 peuvent être formées, de manière non limitative, par pliage de la matière du support 20. The raised edges 86 of the guide surface 78 can be formed, in a non-limiting manner, by folding the material of the support 20.
Tel que visible aux figures 6 et 7, le bord libre 84 de la surface de guidage 78 comprend au moins un élément de maintien 88 du support 20 sur le réservoir 22. L’élément de maintien 88 peut être par exemple formé par des pattes courbées 90 de telle sorte à former des surfaces d’appui qui s’étendent dans des plans transversaux T et verticaux V. As visible in Figures 6 and 7, the free edge 84 of the guide surface 78 comprises at least one holding element 88 of the support 20 on the reservoir 22. The holding element 88 can for example be formed by curved tabs 90 so as to form bearing surfaces which extend in transverse planes T and vertical planes V.
Au moins deux pattes courbées 90 s’étendent alors en décaler l’une de l’autre selon la direction longitudinale L, de telle sorte à permettre le logement d’une bordure du réservoir 22 entre elles. At least two curved legs 90 then extend offset from one another in the longitudinal direction L, so as to allow the accommodation of an edge of the tank 22 between them.
Dit autrement, le décalage longitudinal des deux pattes courbées 90 permet au support de venir en prise de part et d’autre de la bordure du réservoir 22 de telle sorte à bloquer radialement en position le support 20 sur ledit réservoir 22. In other words, the longitudinal offset of the two curved legs 90 allows the support to engage on either side of the edge of the tank 22 so as to block the support 20 radially in position on said tank 22.
Selon l’exemple de l’invention illustré, le support 20 comprend trois pattes courbées 90 dont une patte courbée 90 centrale transversalement, est décalée longitudinalement par rapport aux deux autres pattes courbées 90. According to the example of the invention illustrated, the support 20 comprises three curved legs 90 of which a central curved leg 90 transversely is offset longitudinally relative to the two other curved legs 90.
Selon un exemple non limitatif de l’invention, les pattes courbées 90 sont formées par découpe et pliage de la matière du support 20. According to a non-limiting example of the invention, the curved legs 90 are formed by cutting and folding the material of the support 20.
La paroi de raclage 80 du support 20 s’étend depuis la partie centrale 82 du support 20 évoquée précédemment, et de telle sorte qu’elle s’étende en regard de la surface de guidage 78. En d’autres termes, la surface de guidage 78 et la paroi de raclage 80 sont alignées le long d’une première droite D1 qui est parallèle à la direction longitudinale L. The scraping wall 80 of the support 20 extends from the central part 82 of the support 20 mentioned previously, and such that it extends facing the guide surface 78. In other words, the surface of guide 78 and the scraping wall 80 are aligned along a first straight line D1 which is parallel to the longitudinal direction L.
La paroi de raclage 80 se présente alors comme une paroi qui fait saillie de la partie centrale 82 du support 20 dans un plan vertical V et transversal T et qui présente une complémentarité de forme et de dimension transversale avec l’organe de raclage. The scraping wall 80 then appears as a wall which projects from the central part 82 of the support 20 in a vertical plane V and transverse T and which has a complementary shape and transverse dimension with the scraping member.
On comprend qu’une telle caractéristique permet à la paroi de raclage 80 d’être positionnée de manière optimale afin que la lame de l’organe de raclage vienne lécher une arrête d’extrémité libre de la paroi de raclage 80, lorsque le rouleau est guidé en rotation sur la surface de guidage 78, comme cela est illustré à la figure 7. It is understood that such a characteristic allows the scraping wall 80 to be positioned optimally so that the blade of the scraping member comes to lick a free end edge of the scraping wall 80, when the roller is guided in rotation on the guide surface 78, as illustrated in Figure 7.
Un tel raclage permet alors de débarrasser la lame de l’enduit récolté lors du passage du dispositif d’application contre la bande. Such scraping then makes it possible to rid the blade of the coating collected during the passage of the application device against the belt.
Selon un exemple de l'invention, la paroi de raclage 80 peut comprendre des ouvertures de fixation 92 permettant la fixation d’une glissière en caoutchouc, non visible, fixée par une contreplaqué, non visible, par un procédé de vissage ou rivetage. According to an example of the invention, the scraping wall 80 may comprise fixing openings 92 allowing the fixing of a rubber slider, not visible, fixed by plywood, not visible, by a screwing or riveting process.
Le support 20 comprend par ailleurs des oreilles de fixation 94 au réservoir 22. Les oreilles de fixation 94 s’étendent notamment de part et d’autre de la partie centrale 82 du support 20 et de telle sorte qu’elles soient alignées le long d’une deuxième droite D2 perpendiculaire à la première droite D1 . On comprend alors que les oreilles de fixation 94 s’étendent selon la direction transversale T. The support 20 also comprises fixing ears 94 to the tank 22. The fixing ears 94 extend in particular on either side of the central part 82 of the support 20 and such that they are aligned along 'a second straight line D2 perpendicular to the first straight line D1. We then understand that the fixing lugs 94 extend in the transverse direction T.
Les oreilles de fixation 94 comprennent alors des trous de fixation 96 permettant d’y fixer des équerres, non représentées, de fixation au réservoir 22. The fixing lugs 94 then include fixing holes 96 allowing brackets, not shown, to be fixed to the tank 22.
Selon l’exemple de l’invention, les trous de fixation 96 sont de forme oblongue selon la direction transversale T afin de permettre l'ajustement de la position des équerres selon la direction transversale T. According to the example of the invention, the fixing holes 96 are of oblong shape in the transverse direction T in order to allow adjustment of the position of the brackets in the transverse direction T.
Le support 20 peut ainsi s’adapter à différents diamètres de réservoir 22. The support 20 can thus adapt to different diameters of tank 22.
Selon un exemple avantageux de l’invention, les oreilles de fixation 94 s’étendent chacune sur une dimension transversale comprise entre 25cm et 30cm. According to an advantageous example of the invention, the fixing ears 94 each extend over a transverse dimension of between 25cm and 30cm.
Les oreilles de fixation 94 peuvent comprendre chacune au moins une bordure de renfort 98 périphérique, formée par déformation de la matière du support 20, afin d’améliorer la solidité des oreilles de fixation 94. The fixing ears 94 may each include at least one peripheral reinforcing edge 98, formed by deformation of the material of the support 20, in order to improve the solidity of the fixing ears 94.
Le procédé d’utilisation de l’ensemble d’application 10 de la bande 12 selon un exemple de l’invention va maintenant être décrit plus en détail au moyen des figures 1 à 7. The method of using the application assembly 10 of the strip 12 according to an example of the invention will now be described in more detail using Figures 1 to 7.
Le procédé comprend une première étape, appelé étape de collage de la bande 12, au cours de laquelle on dispose l’enduit en recouvrement au moins de la jointure 14. The process includes a first step, called the strip 12 bonding step, during which the coating is placed to cover at least the joint 14.
Par la suite, on dispose la bande 12 en recouvrement de la jointure 14 et de telle sorte qu’elle soit sensiblement centrée sur la jointure 14. On comprend alors que la bande 12 est maintenue sur la jointure 14 au moyen de l’enduit. Subsequently, the strip 12 is placed to cover the joint 14 and in such a way that it is substantially centered on the joint 14. We then understand that the strip 12 is held on the joint 14 by means of the coating.
Le procédé comprend alors une deuxième étape, au cours de laquelle la bande 12 est serrée, l’excédent d’enduit est retiré et la surface est lissée. Lors de cette deuxième étape, on utilise l’ensemble d’application 10 tel que décrit précédemment. The process then includes a second step, during which the strip 12 is tightened, the excess coating is removed and the surface is smoothed. During this second step, the application assembly 10 is used as described previously.
En effet, l’ensemble d’application 10 de la bande 12 permet avantageusement de réaliser les opérations de la deuxième étape en un seul passage sur la bande 12. Indeed, the application assembly 10 of the strip 12 advantageously allows the operations of the second step to be carried out in a single pass over the strip 12.
Ainsi, on installe le dispositif 18 d'application sur la bande 12 au moyen du manche 76 fixé à ce dernier et on effectue un mouvement en translation le long de la bande 12 en effectuant une pression constante. Thus, the application device 18 is installed on the strip 12 by means of the handle 76 fixed to the latter and a translation movement is carried out along the strip 12 while applying constant pressure.
Plus particulièrement, on déplace le dispositif 18 d’application le long de la bande 12 de telle sorte que le rouleau 30 passe préalablement à l’organe de raclage 32, sur la bande 12. More particularly, the application device 18 is moved along the strip 12 such that the roller 30 passes before the scraping member 32, on the strip 12.
De la sorte, le rouleau 30 plaque la bande 12 contre la jointure 14 et sa forme particulière en double cône inversé permet de diriger l’excèdent d’enduit en périphérie de la bande 12. In this way, the roller 30 presses the strip 12 against the joint 14 and its particular shape in an inverted double cone makes it possible to direct the excess coating to the periphery of the strip 12.
Une fois le rouleau 30 passé sur la bande 12, l’organe de raclage 32 récupère l’excédent d’enduit dirigé en périphérie de la bande 12 par le rouleau 30. Dit autrement, le bord d’extrémité transversal 50 et les ailes 54 de la lame 46 de l’organe de raclage 32 permettent d’une part de récupérer l’enduit et permettent d’autre part de lisser la surface de la bande 12 sur les panneaux 16 en recouvrement de la jointure 14. Once the roller 30 has passed over the strip 12, the scraping member 32 recovers the excess coating directed to the periphery of the strip 12 by the roller 30. In other words, the transverse end edge 50 and the wings 54 of the blade 46 of the scraping member 32 allow on the one hand to recover the coating and on the other hand to smooth the surface of the strip 12 on the panels 16 covering the joint 14.
On comprend par ailleurs que le manche 76 solidaire du dispositif 18 d’application, tel que décrit précédemment permet avantageusement à un opérateur d’utiliser le dispositif 18 d’application sans avoir besoin d’un dispositif d’élévation tel qu’un escabeau. It is also understood that the handle 76 secured to the application device 18, as described above, advantageously allows an operator to use the application device 18 without the need for an elevation device such as a stepladder.
Le manche 76, et notamment l'ensemble comprenant le manche 76 et le plateau 74, dit « manche boîte de finition », maintenu par vissage sur la platine 24, permet par ailleurs d’utiliser le dispositif 18 d’application selon deux directions à savoir du haut vers le bas ou du bas vers le haut, ces directions étant définies par rapport à la surface terrestre représentant le bas et suivant la gravité terrestre. The handle 76, and in particular the assembly comprising the handle 76 and the plate 74, called "finishing box handle", held by screwing on the plate 24, also allows the application device 18 to be used in two directions at namely from top to bottom or from bottom to top, these directions being defined in relation to the earth's surface representing the bottom and following earth's gravity.
Une fois le dispositif 18 d’application passé sur la bande 12, le procédé comprend une troisième étape au cours de laquelle on débrasse l’enduit du dispositif 18 d’application. Ainsi, lors de cette troisième étape, visible à la figure 7, le dispositif 18 d’application est disposé sur le support 20 de telle sorte que le rouleau 30 soit au contact de la partie centrale 82 et que le bord de fixation 48 de la lame 46 de l’organe de raclage 32 soit en regard de la paroi de raclage 80. Le dispositif 18 d’application est par la suite déplacé en translation longitudinale sur le support 20 de telle sorte que le rouleau 30 soit guidé par la surface de guidage 78 tel que décrit précédemment et de telle sorte que la lame 46 glisse le long de la paroi de raclage 80 depuis son extrémité de fixation vers son bord d’extrémité transversal, la débarrassant ainsi de l’enduit récolté. Once the application device 18 has passed over the belt 12, the process comprises a third step during which the coating is removed from the application device 18. Thus, during this third step, visible in Figure 7, the application device 18 is arranged on the support 20 such that the roller 30 is in contact with the central part 82 and the fixing edge 48 of the blade 46 of the scraping member 32 faces the scraping wall 80. The application device 18 is subsequently moved in longitudinal translation on the support 20 so that the roller 30 is guided by the surface of guide 78 as described above and such that the blade 46 slides along the scraping wall 80 from its fixing end towards its transverse end edge, thus ridding it of the collected coating.
L’enduit récolté s’écoule alors dans le réservoir 22 au-dessus duquel est disposé le support 20. The collected coating then flows into the tank 22 above which the support 20 is placed.
Ainsi, on tire avantage de l’ensemble d’application tel qu’il vient d’être décrit en ce qu’il permet de faciliter la pose d’une bande à une jointure de deux panneaux constitutifs d’un mur en assurant simultanément l’étape de serrage de la bande, l’étape de retrait d’excédent d’enduit et l’étape de lissage de la bande. Le dispositif d’application réduit ainsi les étapes nécessaires à la pose de bande pour un opérateur et permet de manière efficace d’appliquer la bande sur l’intégralité de la jointure indépendamment de la hauteur du mur, notamment au moyen de l’élément de fixation du manche. Thus, we take advantage of the application assembly as it has just been described in that it makes it possible to facilitate the installation of a strip at a joint of two panels constituting a wall while simultaneously ensuring the the step of tightening the strip, the step of removing excess coating and the step of smoothing the strip. The application device thus reduces the steps necessary for installing the strip for an operator and effectively allows the strip to be applied to the entire joint independently of the height of the wall, in particular by means of the fixing element. fixing the handle.
