Description

Domaine techniqueTechnical area

La présente invention concerne le domaine de la pose de revêtements à lames sur une paroi, et en particulier sur une paroi non horizontale de type mur, ou sur une paroi de type plafond. Plus précisément dans ce domaine la présente invention concerne des lames de revêtement qui sont assemblables bord à bord par emboîtement autobloquant, et des accessoires de pose permettant de solidariser lesdites lames de revêtement avec une paroi de manière à former un revêtement à pose fixe ou flottante.The present invention relates to the field of the laying of blade coatings on a wall, and in particular on a wall-type non-horizontal wall, or on a ceiling type wall. More specifically in this field the present invention relates to coating blades which are assembled edge-to-edge interlocking interlocking, and installation accessories for securing said coating blades with a wall so as to form a fixed or floating coating.

Art antérieurPrior art

Parmi l'ensemble des revêtements connus pouvant être posés au sol, on connaît des parquets décoratifs constitués de lames décoratives emboîtées bord à bord avec un blocage l'une par rapport à l'autre de deux lames emboîtées. Une lame présente le plus souvent une forme générale rectangulaire, mais peut également être de forme carrée. Ces lames de revêtement peuvent être emboîtées avec des lames voisines uniquement sur deux côtés opposés des lames ou sur tous les côtés des lames.Among all the known coatings that can be placed on the ground, there are known decorative floors consisting of decorative blades nested edge to edge with a locking relative to each other two nested blades. A blade most often has a general rectangular shape, but can also be square. These lining blades can be nested with adjacent blades only on two opposite sides of the blades or on all sides of the blades.

Pour leur emboîtement, ces lames comportent au moins deux bords opposés, qui sont profilés de manière à former des éléments d'accouplement complémentaires comportant respectivement au moins une rainure délimitée par deux lèvres avant et arrière, et une languette emboîtable dans la rainure entre les deux lèvres.For their interlocking, these blades comprise at least two opposite edges, which are profiled so as to form complementary coupling elements respectively comprising at least one groove delimited by two front and rear lips, and a tongue interlocking in the groove between the two. lips.

Pour le blocage des lames, lesdits éléments d'accouplement comportent en outre des moyens de verrouillage mécanique qui empêchent l'écartement réciproque de deux lames accouplées, dans un plan parallèle à leur face inférieure sensiblement plane, et dans une direction perpendiculaire à leurs bords accouplés. Ces moyens de verrouillage mécanique comportent le plus souvent un ergot de blocage en saillie sur la languette et un renfoncement ménagé dans la lèvre inférieure de la rainure et apte à recevoir ledit ergot de blocage.For locking the blades, said coupling elements further comprise mechanical locking means which prevent the mutual spacing of two coupled blades, in a plane parallel to their substantially flat bottom face, and in a direction perpendicular to their mating edges. . These mechanical locking means most often comprise a locking lug projecting from the tongue and a recess formed in the lower lip of the groove and able to receive said locking pin.

Il existe à ce jour de nombreux profils de bords de lames permettant un tel emboîtement bord à bord et autobloquant des lames. A titre d'exemples non exhaustifs, les publications ci-après illustrent différents exemples de lames assemblables par emboîtement bord à bord et autobloquant : demandes de brevet internationales WO96/27721 , WO97/47834 et WO 99/66151 ; brevets américains US 4 426 820 , US 7 444 791 , US 8 011 155 et US 8 495 849 .To this day, there are many blade edge profiles allowing such interlocking edge-to-edge and self-locking blades. By way of non-exhaustive examples, the following publications illustrate various examples of blades assembled by interlocking edge-to-edge and self-blocking: international patent applications WO96 / 27721 , WO97 / 47834 and WO 99/66151 ; US patents US 4,426,820 , US 7,444,791 , US 8,011,155 and US 8,495,849 .

A ce jour, les lames assemblables bord à bord par emboîtement autobloquant, telles que celles décrites dans les publications susvisées sont adaptées et utilisées pour réaliser des revêtements de sol, notamment des revêtements de sol à pose flottante.To date, the self-locking interlocking boards edge-to-edge, such as those described in the aforementioned publications are adapted and used to produce floor coverings, including floating floor coverings.

Si l'on souhaite en revanche poser ces lames assemblables bord à bord par emboîtement autobloquant sur une paroi non horizontale, telle qu'un mur, pour constituer un revêtement mural, ou sur un plafond, on est contraint à ce jour de fixer chaque lame sur la paroi en la clouant, en la vissant ou en l'agrafant au moyen de clous, vis ou agrafes passés à travers la lèvre arrière de la rainure d'emboîtement de l'un de leur bord. Cette technique de pose n'est pas pratique et surtout oblige à réaliser un revêtement à pose fixe et ne permet pas de réaliser un revêtement mural ou un revêtement de plafond à pose flottante. En outre, dans certains cas, la lèvre arrière de la rainure d'emboîtement du bord de la lame n'est pas suffisamment longue pour permettre une telle fixation, tel que par exemple pour les profils de lames décrits dans la demande de brevet internationale WO97/47834 . Les fabricants des ces lames sont donc contraints de réaliser des profils de lames spécifiques avec lèvre arrière plus longues pour réaliser des revêtements muraux.However, if it is desired to install these blades assembled edge-to-edge interlocking interlocking on a non-horizontal wall, such as a wall, to form a wall covering, or on a ceiling, we are forced to date to fix each blade on the wall by nailing it, screwing it or stapling it by means of nails, screws or staples passed through the rear lip of the interlocking groove of one of their edge. This installation technique is not practical and especially requires to achieve a fixed-laying coating and does not allow for a wall covering or a floating ceiling coating. In addition, in some cases, the rear lip of the interlocking groove of the edge of the blade is not long enough to allow such a fastening, such as for example for the blade profiles described in the international patent application. WO97 / 47834 . The manufacturers of these blades are therefore forced to make specific blade profiles with longer rear lip to make wall coverings.

A cause des ces difficultés, les lames assemblables bord à bord par emboîtement autobloquant sont à ce jour rarement utilisées pour réaliser des revêtements de mur ou de plafond, mais sont essentiellement utilisées pour réaliser des revêtements de sol.Because of these difficulties, self-locking interlocking edge-to-edge blades are rarely used to make wall or ceiling coverings, but are mainly used for floor coverings.

Il est par ailleurs connu des revêtements muraux ou de plafond à base de lames emboîtables bord à bord de type lambris. Ces lames de type lambris peuvent comporter au niveau de leurs bords opposés une rainure d'emboîtement et une languette pour leur emboitement bord à bord, mais ne comportent pas de moyens de verrouillage mécanique permettant un emboîtement autobloquant.It is also known wall coverings or ceiling panels based on edge-to-edge boarding panels. These panel-type blades may comprise at their opposite edges an interlocking groove and a tab for their interlocking edge to edge, but do not include mechanical locking means for interlocking interlocking.

Selon une technique de pose de lambris connue, on commence par fixer sur la paroi une pluralité de lattes destinées à former un support de pose pour les lames. Ces lattes sont fixées sur la paroi, par exemple par vissage, en étant disposées parallèlement les unes aux autres et espacées dans la direction perpendiculaire à leur axe longitudinal. Il peut également être avantageux que les lattes soient espacées selon leur direction longitudinale en sorte de ménager ultérieurement un passage pour une circulation d'air entre les lattes, et sous le revêtement décoratif.According to a known paneling installation technique, it is first fixed on the wall a plurality of slats for forming a laying support for the blades. These slats are fixed on the wall, for example by screwing, being arranged parallel to each other and spaced apart in the direction perpendicular to their longitudinal axis. It may also be advantageous if the slats are spaced in their longitudinal direction so as to subsequently provide a passage for air circulation between the slats, and under the decorative coating.

Une fois le support de pose à lattes fixé sur la paroi, on pose les lambris, en positionnant chaque lambris sur les lattes du support de pose et en fixant individuellement chaque lambris sur chaque latte sous-jacente du support de pose, et le cas échéant en emboîtant jointivement deux à deux les lames décoratives le long de leurs bords longitudinaux. A l'origine de cette technique de pose, les lattes étaient constituées de tasseaux en bois, et les lames de revêtement étaient fixées par clouage ou vissage sur les lattes en bois.Once the slatted installation support is fixed on the wall, the paneling is placed, positioning each paneling on the slats of the installation support and fixing individually each paneling on each latte underlying the installation support, and if necessary by joining the two decorative blades together along their longitudinal edges. At the origin of this technique of laying, the slats consisted of wooden cleats, and the cladding boards were fixed by nailing or screwing on the wooden slats.

On a également proposé de remplacer la fixation par clouage, vissage ou agrafage, par une fixation au moyen d'éléments de fixation individuels rapportés, de type clips de fixation, généralement en métal, et positionnés à l'interface entre chaque lame et chaque latte sous-jacente, et au niveau de la jointure entre deux lames décoratives juxtaposées. Cette solution de pose est par exemple décrite dans la demande de brevet WO 03/004796 . Les clips de fixation divulgués dans cette publication sont conçus de manière à permettre leur emboîtement sur un bord d'une lame de revêtement. En outre, dans cette publication WO03/004796 , les lattes forment des rails de pose le long desquels les clips de fixation peuvent coulisser individuellement.It has also been proposed to replace the fixing by nailing, screwing or stapling, by fixing by means of individual fasteners reported, fastening type of clips, usually made of metal, and positioned at the interface between each blade and each slat underlying, and at the joint between two decorative blades juxtaposed. This laying solution is for example described in the patent application WO 03/004796 . The fastening clips disclosed in this publication are designed to allow them to nest on one edge of a liner blade. In addition, in this publication WO03 / 004796 , the slats form laying rails along which the fixing clips can slide individually.

Les clips de fixation décrits dans cette publication WO03/004796 ne sont pas adaptés et ne peuvent être utilisés pour fixer des lames assemblables bord à bord par emboîtement autobloquant. La demande de brevet internationale WO2007/115747 divulgue un ensemble d'au moins deux lames de revêtement présentant les caractéristiques techniques du préambule de la revendication 1.The fixing clips described in this publication WO03 / 004796 are not suitable and can not be used to attach self-locking interlocking boards. International patent application WO2007 / 115747 discloses a set of at least two cladding blades having the technical features of the preamble of claim 1.

On a représenté sur les figures 1 à 3 un premier exemple connu d'assemblage bord à bord de lames de revêtement 1 identiques, mettant en oeuvre un principe d'emboîtement bord à bord autobloquant, avec plus particulièrement un serrage élastique des lames l'une par rapport à l'autre. Ce type d'emboîtement bord à bord autobloquant de lames de revêtement avec un serrage élastique est à ce jour principalement connu sous la désignation Uniclic®.We have shown on Figures 1 to 3 a first known example of edge-to-edge assembly of identical lining blades 1, implementing a self-locking edge-to-edge interlocking principle, with more particularly an elastic clamping of the blades relative to one another. This type of self-locking edge-to-edge interlocking of cladding blades with elastic clamping is so far mainly known under the designation Uniclic®.

On a représenté sur la figure 4 un deuxième exemple connu d'assemblage bord à bord de lames de revêtement l'identiques, mettant en oeuvre un principe d'emboîtement bord à bord autobloquant avec serrage élastique des lames l'une par rapport à l'autre, de type Uniclic®. Ces assemblages de type Uniclic® sont décrits notamment dans la demande de brevet internationale WO97/47834 .We have shown on the figure 4 a second known example of edge-to-edge assembly of identical cladding blades, implementing a self-locking edge-to-edge interlocking principle with elastic clamping of the blades relative to each other, of the Uniclic® type. These Uniclic® type assemblies are described in particular in the international patent application WO97 / 47834 .

On a représenté sur la figure 5 un troisième exemple connu d'assemblage bord à bord de lames de revêtement 1" identiques, mettant en oeuvre un principe d'emboîtement bord à bord autobloquant, sans serrage élastique des lames l'une par rapport à l'autre. Cet assemblage est décrit par exemple dans le brevet américain US 7 444 791 . Dans cette variante d'assemblage, l'accouplement bord à bord des deux lames 1", et leur auto-blocage l'une par rapport à l'autre, sont réalisés avec un léger jeu entre les lames 1 ".We have shown on the figure 5 a third known example of edge-to-edge assembly of identical lining blades 1 ", implementing a self-locking edge-to-edge interlocking principle, without elastic clamping of the blades relative to one another. for example in the US patent US 7,444,791 . In this assembly variant, the coupling edge to edge of the two blades 1 ", and their self-locking relative to each other, are made with a slight clearance between the blades 1".

On a représenté sur la figure 6 un quatrième exemple connu d'assemblage bord à bord de lames de revêtement 1'" identiques, mettant en oeuvre un principe d'emboîtement bord à bord autobloquant, sans serrage élastique des lames l'une par rapport à l'autre.We have shown on the figure 6 a fourth known example of edge-to-edge assembly of identical lining blades 1 ", implementing a self-locking edge-to-edge interlocking principle, without elastic clamping of the blades relative to each other.

Les lames de revêtement 1, 1', 1" ou 1'" sont des plaques monobloc pouvant être de forme rectangulaire ou carrée, d'épaisseur E. Chaque lame peut par exemple être réalisée à partir d'un profilé en bois massif, en stratifié ou mélaminé, ou en matière plastique, et notamment en PVC (Polychlorure de Vinyle). La face avant 10 de d'une lame peut comporter une ou plusieurs couches de surface, par exemple sous la forme d'un film monocouche ou multicouche, notamment en plastique, papier, mélamine ou placage bois, fixé par tout moyen connu, et notamment par collage et/ou thermocollage. Ce revêtement de surface de la lame peut remplir une fonction décorative, et/ou une fonction de protection contre l'usure. La face arrière 11 de chaque lame est destinée à être orientée vers la paroi de pose du revêtement, et est sensiblement plane. Les lames 1, 1', 1", 1'" peuvent être fabriquées par tout moyen de fabrication connu, et notamment par extrusion, usinage ou moulage.The cladding blades 1, 1 ', 1 "or 1'" are monobloc plates that can be rectangular or square, of thickness E. Each blade can for example be made from a solid wood profile, in laminate or melamine, or plastic, and in particular PVC (Polyvinyl chloride). The front face 10 of a blade may comprise one or more surface layers, for example in the form of a monolayer or multilayer film, in particular of plastic, paper, melamine or wood veneer, fixed by any known means, and in particular by gluing and / or heat-sealing. This surface coating of the blade can fulfill a decorative function, and / or a function of protection against wear. The rear face 11 of each blade is intended to be oriented towards the laying wall of the coating, and is substantially flat. The blades 1, 1 ', 1 ", 1" "can be manufactured by any known manufacturing means, and in particular by extrusion, machining or molding.

En référence à la figure 1, les deux bords opposés 12 et 13 d'une lame 1 sont profilés de manière à former des éléments d'accouplement complémentaires comportant respectivement une rainure d'emboîtement 120 et une languette 130 emboîtable dans la rainure d'emboîtement 120. La rainure d'emboîtement 120 est délimitée par deux lèvres avant 121 et arrière 122.With reference to the figure 1 , the two opposite edges 12 and 13 of a blade 1 are profiled so as to form complementary coupling elements respectively comprising a nesting groove 120 and a tongue 130 engageable in the interlocking groove 120. The groove nesting 120 is delimited by two lips before 121 and rear 122.

La lèvre avant 121 est suffisamment courte et épaisse pour être sensiblement indéformable en usage normal.The front lip 121 is sufficiently short and thick to be substantially indeformable in normal use.

La lèvre arrière 122 de longueur L2 (figure 1) supérieure à la longueur L1 de la lèvre avant 121, est élastiquement déformable dans un plan (X,Y) perpendiculaire au bord correspondant 12 de la lame, de manière à permettre un léger écartement de la lèvre arrière 122 par rapport à la lèvre avant 121.The rear lip 122 of length L 2 ( figure 1 ) greater than the length L 1 of the front lip 121, is elastically deformable in a plane (X, Y) perpendicular to the corresponding edge 12 of the blade, so as to allow a slight spacing of the rear lip 122 relative to the lip before 121.

De préférence, mais non nécessairement, pour des raisons de meilleure stabilité de l'emboîtement des lames, la différence de longueur ΔL (ΔL =L2 - L1) entre les deux lèvres 121 et 122, mesurée dans un plan (XY) perpendiculaire à leur face arrière 11 et perpendiculairement à la direction longitudinale (Z) de la rainure d'emboîtement 120, est de préférence inférieure ou égale à l'épaisseur E des lames 1. A titre d'exemple non limitatif de l'invention, l'épaisseur E des lames 1 est par exemple inférieure à 20mm, voire inférieure à 15mm.Preferably, but not necessarily, for reasons of better stability of the engagement of the blades, the difference in length ΔL (ΔL = L 2 - L 1 ) between the two lips 121 and 122, measured in a plane (XY) perpendicular at their rear face 11 and perpendicularly to the longitudinal direction (Z) of the engagement groove 120, is preferably less than or equal to the thickness E of the blades 1. As a non-limiting example of the invention, E thickness of the blades 1 is for example less than 20mm, or even less than 15mm.

Les bords 12 ,13 des lames 1 comportent également des moyens de verrouillage mécanique 123, 133 qui empêchent l'écartement réciproque de deux lames 1 accouplées, dans un plan (X,Z) parallèle à leur face inférieure 11 et dans une direction (figure 1/ axe X) perpendiculaire à la direction longitudinale (Z) de leurs bords accouplés. Dans la variante des figures 1 à 3, ces moyens de verrouillage mécanique sont constitués par un ergot de verrouillage 133 en saillie sur la languette 13, et par une rainure ou renfoncement de blocage 123, sensiblement en forme de V, ménagé dans la face interne 122a de la lèvre arrière 122 (Figure 3). La face interne 122a de la lèvre arrière 122 présente ainsi un profil non linéaire incluant ledit renfoncement de blocage 123.The edges 12, 13 of the blades 1 also comprise mechanical locking means 123, 133 which prevent the mutual spacing of two coupled blades 1, in a plane (X, Z) parallel to their lower face 11 and in one direction ( figure 1 X axis) perpendicular to the longitudinal direction (Z) of their coupled edges. In the variant of Figures 1 to 3 these mechanical locking means consist of a locking lug 133 projecting from the tongue 13, and a substantially V-shaped groove or locking recess 123 formed in the internal face 122a of the rear lip 122 ( Figure 3 ). The inner face 122a of the rear lip 122 thus has a non-linear profile including said locking recess 123.

La figure 3 montre une phase initiale d'emboîtement des deux lames. Sur cette figure 3, les pointillés représentent la lèvre arrière 122 au repos à l'état non déformée, avant emboîtement de la languette 13 dans la rainure 12. On suppose que la lame 1 de gauche est posée sur une paroi, sa face arrière 11 étant au contact de ladite paroi. L'insertion de la languette 13 dans la rainure 12 est réalisée dans un premier temps en inclinant la lame 1 de droite par rapport au plan (X,Z) parallèle au plan de pose de la face arrière 11 de l'autre lame 1, et introduisant la partie distale de la languette 13 dans la rainure 12 jusqu'à ce que l'ergot de blocage 133 soit au contact de la lèvre arrière 122. Puis on fait pivoter (Figure 3/ Flèche G1) la lame 1 de droite et on la déplace latéralement en direction de l'autre lame (Figure 3/ Flèche G2), de manière à faire pénétrer plus profondément la languette 13 dans la rainure 12. Ce mouvement permet d'exercer par effet de levier une pression sur la lèvre arrière 122, qui la déforme élastiquement en la forçant à s'écarter suffisamment de l'autre lèvre 121 pour permettre le positionnement de l'ergot de blocage 133 dans le renfoncement de blocage 123. Cette déformation de la lèvre arrière 122 est possible par exemple lorsque les lames sont posées sur une sous-couche en matériau compressible ; dans ce cas sous l'effet de levier, la lèvre arrière 122 est déformée en comprimant localement ladite sous-couche. Lorsque les lames 1 sont posées au contact d'une sous-couche dure ou d'un support de pose dur, sous l'effet de levier on obtient de manière connue une déformation élastique de la lèvre inférieure 122 par un très léger soulèvement d'une partie de la lame correspondante par rapport à la sous-couche ou au support de pose.The figure 3 shows an initial phase of nesting of the two blades. On this figure 3 , the dots represent the rear lip 122 at rest in the undeformed state, before interlocking of the tongue 13 in the groove 12. It is assumed that the blade 1 of the left is placed on a wall, its rear face 11 being in contact with said wall. The insertion of the tongue 13 into the groove 12 is made in a first step by inclining the blade 1 from the right relative to the plane (X, Z) parallel to the laying plane of the rear face 11 of the other blade 1, and introducing the distal portion of the tongue 13 in the groove 12 until the locking pin 133 is in contact with the rear lip 122. Then it is rotated ( Figure 3 / Arrow G 1 ) the right blade 1 and move it laterally towards the other blade ( Figure 3 / Arrow G 2 ), so as to penetrate the tongue 13 deeper into the groove 12. This movement makes it possible to exert by leverage a pressure on the rear lip 122, which deforms it elastically by forcing it to move apart enough of the other lip 121 to allow the positioning of the locking pin 133 in the locking recess 123. This deformation of the rear lip 122 is possible for example when the blades are placed on a sub-layer of compressible material; in this case under the leverage effect, the rear lip 122 is deformed by locally compressing said underlayer. When the blades 1 are placed in contact with a hard underlay or a hard laying support, under the effect of leverage is obtained in known manner an elastic deformation of the lower lip 122 by a very slight lifting of a part of the corresponding blade relative to the underlayer or the laying medium.

En référence à la figure 2, une fois l'emboîtement terminé, les faces arrière 11 des lames 1 sont sensiblement coplanaires (plan X,Z). La lèvre arrière 122 est en contact plan avec l'ergot de biocage133 dans une zone de contact Z1. Dans cette zone de contact Z1, la distance entre la face interne 122a de la lèvre arrière 122 et la languette 13 est nulle.With reference to the figure 2 once the nesting is complete, the rear faces 11 of the blades 1 are substantially coplanar (X, Z plane). The rear lip 122 is in plane contact with the biotraping pin 133 in a contact zone Z 1 . In this contact zone Z 1 , the distance between the inner face 122a of the rear lip 122 and the tongue 13 is zero.

La lèvre arrière 122 est en outre légèrement élastiquement déformée de telle sorte qu'elle exerce sur la languette 13 insérée dans la rainure 12, dans la zone de contact Z1, une force de serrage (Figure 2/ Flèche F) qui contribue à rapprocher les deux lames et à les maintenir serrées en butée l'une contre l'autre dans les zones de contact Z2 et Z3. Dans cette variante, l'accouplement bord à bord des deux lames 1, et leur auto-blocage l'une par rapport à l'autre, sont ainsi réalisés sans jeu entre les lames 1.The rear lip 122 is furthermore slightly elastically deformed so that it exerts on the tongue 13 inserted in the groove 12, in the contact zone Z 1 , a clamping force ( Figure 2 / Arrow F) which contributes to bring the two blades together and keep them tight abutted against each other in the contact zones Z 2 and Z 3 . In this variant, the coupling edge to edge of the two blades 1, and their self-locking relative to each other, are thus made without clearance between the blades 1.

On a représenté sur les figures 7 et 8, un exemple d'accessoire de pose qui comprend un élément de liaison 2, permettant de fixer le bord (avec rainure 120) d'une lame 1 sur une paroi, tout en permettant un emboîtement bord à bord autobloquant d'une autre lame 1 sur le bord opposé.We have shown on Figures 7 and 8 , an example of a fitting accessory which comprises a connecting element 2, for fixing the edge (with groove 120) of a blade 1 on a wall, while allowing interlocking edge-to-edge interlocking of another blade 1 on the opposite side.

Cet élément de liaison 2 est par exemple une patte rigide ou semi rigide en plastique ou en métal, de très faible épaisseur, qui a été mise en forme. Cet élément de liaison 2 peut également être en tout ou partie en carton ou en papier, notamment lorsqu'on cherche à réaliser un élément de liaison qui peut être écrasé entre une languette 130 emboîtée dans une rainure 120 et la lèvre arrière 122 de ladite rainure, afin de réduire son épaisseur.This connecting element 2 is for example a rigid or semi-rigid plastic or metal lug, very thin, which has been shaped. This connecting element 2 may also be wholly or partly made of cardboard or paper, particularly when it is desired to make a connecting element that can be crushed between a tongue 130 fitted into a groove 120 and the rear lip 122 of said groove , to reduce its thickness.

Cet élément de liaison 2 comporte ainsi une première partie 20, d'épaisseur e1, qui est adaptée pour être positionnée dans la rainure 12 d'une lame 1, au contact de la face interne 122a de la lèvre arrière 122. A une première extrémité, la première partie 20 se termine par un bourrelet d'écrasement 22 de plus grande épaisseur, obtenu par exemple par repliement de matière. A son extrémité opposée, la première partie 20 est prolongée par une deuxième partie 21, qui dans cet exemple particulier a un profil transversal essentiellement en forme de L. Dans cet exemple particulier, l'épaisseur de la deuxième partie 21 est sensiblement égale à celle (e1) de la première partie 20. Dans une autre variante, l'épaisseur de la deuxième partie 21 pourrait être différente et notamment supérieure à celle (e1) de la première partie 20.This connecting element 2 thus comprises a first part 20, of thickness e 1 , which is adapted to be positioned in the groove 12 of a blade 1, in contact with the internal face 122a of the rear lip 122. At a first end, the first portion 20 ends with a crimping bead 22 of greater thickness, obtained for example by folding material. At its opposite end, the first portion 20 is extended by a second portion 21, which in this particular example has a substantially L-shaped transverse profile. In this particular example, the thickness of the second portion 21 is substantially equal to that of the second portion 21. (e 1 ) of the first part 20. In another variant, the thickness of the second portion 21 could be different and in particular greater than that (e 1 ) of the first portion 20.

Dans cette variante particulière, la deuxième partie 21 de l'élément de liaison comporte au moins un trou traversant 21c, pour le passage d'une vis, d'un clou ou d'une agrafe de fixation.In this particular embodiment, the second portion 21 of the connecting element comprises at least one through hole 21c, for the passage of a screw, a nail or a fastening clip.

Pour poser un revêtement à lames 1 sur une paroi P au moyen d'éléments de liaison 2, on procède de la manière suivante.To lay a blade liner 1 on a wall P by means of connecting elements 2, the procedure is as follows.

En référence à la figure 9, on pose une lame 1 au contact de la paroi P (face arrière 11 au contact de la paroi P). La paroi P peut être directement une paroi telle qu'un mur, plafond ou sol, avec éventuellement une sous-couche interposée, ou comme illustré sur la figure 11, peut être formée par un support de pose composé de tasseaux ou lattes T fixés sur une paroi et définissant un plan de pose P.With reference to the figure 9 , a blade 1 is placed in contact with the wall P (rear face 11 in contact with the wall P). The wall P can be directly a wall such as a wall, ceiling or floor, possibly with an interposed underlayer, or as illustrated in FIG. figure 11 , can be formed by a laying support composed of cleats or slats T fixed on a wall and defining a laying plane P.

Si cette lame 1 est une lame posée en premier et appartenant ainsi au bord du revêtement, on fixe sur la paroi P le bord 13 de la lame comportant la languette 130, par tout moyen de fixation approprié, et par exemple par vissage, agrafage ou clouage.If this blade 1 is a blade laid first and thus belonging to the edge of the coating, is fixed on the wall P the edge 13 of the blade having the tongue 130, by any suitable fastening means, for example by screwing, stapling or nailing.

Une fois la lame 1 posée, on fixe sur la paroi P son bord opposé 12 au moyen d'un ou plusieurs éléments de liaison 2 (figure 9). A cet effet, on positionne la première partie 20 de chaque élément de liaison 2 dans la rainure 12 de la lame 1. En référence à la figure 12, la première partie 20 de l'élément de liaison 2 présente un profil courbe identique à celui de la face interne 122a de la lèvre arrière 122. L'élément de liaison 2 épouse ainsi ladite face interne 122a de la lèvre arrière 20 sur une zone de fixation Z qui s'étend depuis un point A situé dans le renfoncement de blocage 123 jusqu'à un point B situé à la jonction entre la face interne 122a et la face latérale 122b de la lèvre arrière 122. La deuxième partie 21 de l'élément de liaison 2 est située à l'extérieur de la rainure 12 et prolonge la première partie 20 au delà de la face latérale 122b de la lèvre arrière 122. Plus particulièrement une branche 21a de la deuxième partie 21 de l'élément de liaison 2 s'étend sensiblement parallèlement à la face latérale 122b de la lèvre arrière 122 sans être au contact de cette face latérale 122b, et une deuxième branche 21b de la deuxième partie 21 de l'élément de liaison 2 est positionnée à plat contre la paroi P. Ensuite, on fixe rigidement l'élément de liaison 2 sur la paroi P au moyen d'une vis, d'un clou ou d'une agrafe 3 passé à travers la deuxième branche 21b de la deuxième partie 21 de l'élément de liaison 2 et pénétrant dans la paroi de pose P. Les éléments liaison 2 permettent ainsi de bloquer le bord 12 de la lame 1 par rapport à la paroi P.Once the blade 1 is placed, the wall P is fixed on its opposite edge 12 by means of one or more connecting elements 2 ( figure 9 ). For this purpose, the first part 20 of each connecting element 2 is positioned in the groove 12 of the blade 1. With reference to FIG. figure 12 , the first part 20 of the connecting element 2 has a curved profile identical to that of the inner face 122a of the rear lip 122. The connecting element 2 thus marries said inner face 122a of the rear lip 20 on a zone fastening Z which extends from a point A in the locking recess 123 to a point B located at the junction between the inner face 122a and the lateral face 122b of the rear lip 122. The second part 21 of the connecting element 2 is located outside the groove 12 and extends the first part 20 beyond the lateral face 122b of the rear lip 122. More particularly, a branch 21a of the second part 21 of the connecting element 2 extends substantially parallel to the lateral face 122b of the rear lip 122 without being in contact with this side face 122b, and a second branch 21b of the second portion 21 of the connecting element 2 is positioned flat against Then, the connecting element 2 is rigidly fixed to the wall P by means of a screw, a nail or a staple 3 passed through the second branch 21b of the second part 21 of the the connecting element 2 and penetrating into the laying wall P. The link elements 2 and allow to block the edge 12 of the blade 1 relative to the wall P.

Une fois la lame 1 fixée à la paroi P au niveau de son bord 12, on emboîte la languette 130 d'une autre lame 1 dans la rainure 12 de la lame 1 qui est fixée au moyen des éléments de liaison 2 (Figures 13 à 15), en procédant de la même manière que précédemment décrit pour l'emboîtement autobloquant de deux lames 1 sans mise en oeuvre d'élément de liaison 2. Une fois les deux lames 1 emboitées, les éléments de liaison 2 sont avantageusement masqués par les lames 1 et ne sont pas visibles.Once the blade 1 is fixed to the wall P at its edge 12, the tongue 130 of another blade 1 is engaged in the groove 12 of the blade 1 which is fixed by means of the connecting elements 2 ( Figures 13 to 15 ), proceeding in the same manner as previously described for the interlocking self-locking two blades 1 without implementation of connecting element 2. Once the two blades 1 nested, the connecting elements 2 are advantageously masked by the blades 1 and are not visible.

On réitère ses étapes de pose avec de nouvelles lames 1 jusqu'à ce que la dernière lame soit posée (lame en périphérie du revêtement). Pour chaque dernière lame posée périphérie i du revêtement, on fixe sur la paroi P le bord 12 (avec rainure 120) de cette lame, par tout moyen de fixation approprié, et par exemple par vissage, agrafage ou clouage.We repeat its laying steps with new blades 1 until the last blade is placed (blade around the coating). For each last blade placed periphery i of the coating, is fixed on the wall P the edge 12 (with groove 120) of this blade, by any suitable fastening means, for example by screwing, stapling or nailing.

En référence à la figure 14, par effet de levier, lors de l'insertion de la languette 130 dans la rainure 120, la lèvre arrière 122 est déformée élastiquement avec une amplitude suffisante pour permettre un emboîtement autobloquant de languette 130 dans la rainure 120 malgré le surplus d'épaisseur (e1) de l'élément de liaison 2. A titre d'exemple non limitatif, l'épaisseur (e1) est de préférence très faible, et par exemple inférieure ou égale à 0,5mm.With reference to the figure 14 , by levering, during the insertion of the tongue 130 into the groove 120, the rear lip 122 is elastically deformed with a sufficient amplitude to allow interlocking interlocking tongue 130 in the groove 120 despite the excess thickness ( e 1 ) of the connecting element 2. By way of non-limiting example, the thickness (e 1 ) is preferably very small, and for example less than or equal to 0.5 mm.

Dans la zone correspondant à la zone de contact Z1 susvisée (entre la languette 130 et la lèvre inférieure 122 en absence d'élément de liaison 2), on obtient un serrage de la première partie 20 de l'élément de liaison 2 entre la lèvre arrière 122 et la languette 130 introduite dans la rainure 12. Ce serrage permet de bloquer en position l'élément de liaison 2 entre la languette 130 et la lèvre arrière 122.In the zone corresponding to the above-mentioned contact zone Z 1 (between the tongue 130 and the lower lip 122 in the absence of a connecting element 2), a tightening of the first part 20 of the connecting element 2 between the rear lip 122 and the tongue 130 introduced into the groove 12. This clamping allows to lock in position the connecting element 2 between the tongue 130 and the rear lip 122.

Dans l'exemple particulier d'assemblage de la figure 2, au-delà de la zone de contact Z1, au niveau du renfoncement de blocage 123, dans une zone Z4 l'ergot de blocage 133 n'est pas en contact avec la face interne 122a de la lèvre arrière 122. Il subsiste dans cette zone Z4, entre l'ergot de blocage 133 et la face interne 122a de la lèvre arrière 122, un espace 124 dont la largeur (d4) est supérieure à l'épaisseur (e1) de la première partie 20 de l'élément de liaison 2, mais est inférieure à l'épaisseur du bourrelet d'écrasement 22 de l'élément de liaison 2. Il en résulte que lors de l'insertion de la languette 130, le bourrelet d'écrasement 22 est écrasé entre l'ergot de blocage 133 de la languette 130 et la face interne 122a de la lèvre arrière 122 (Figure 15). Cet écrasement du bourrelet d'écrasement 22 contribue à améliorer l'immobilisation de l'élément de liaison 2 par serrage de cet élément entre la languette 130 et la face interne 122a de la lèvre arrière 122.In the particular example of assembling the figure 2 beyond the contact zone Z 1 , at the blocking recess 123, in a zone Z4, the locking pin 133 is not in contact with the internal face 122a of the rear lip 122. It remains in this zone Z4, between the locking pin 133 and the inner face 122a of the rear lip 122, a space 124 whose width (d 4 ) is greater than the thickness (e 1 ) of the first part 20 of the connecting element 2, but is smaller than the thickness of the crimping bead 22 of the connecting element 2. As a result, during the insertion of the tongue 130, the crush bead 22 is crushed between locking tab 133 of the tongue 130 and the inner face 122a of the rear lip 122 ( Figure 15 ). This crushing of the crushing bead 22 contributes to improving the immobilization of the connecting element 2 by clamping this element between the tongue 130 and the internal face 122a of the rear lip 122.

Bien que la fixation des bords 12 avec rainure 120 des lames 1 sur une paroi P au moyen des éléments de liaison 2 soit plus spécifiquement utile pour la pose d'un revêtement à lames 1 sur un mur ou sur un plafond, il est néanmoins possible de poser également un revêtement à lames 1 au moyen d'éléments de liaison 2 sur un sol.Although the fixing of the edges 12 with groove 120 of the blades 1 on a wall P by means of the connecting elements 2 is more specifically useful for laying a louvered coating 1 on a wall or a ceiling, it is nevertheless possible to also lay a blade liner 1 by means of connecting elements 2 on a floor.

On a représenté sur les figures 16 et 17, un exemple d'accessoire de pose qui comprend un élément de liaison 2', permettant de fixer le bord 12 avec rainure 120 d'une lame 1' susvisée (figure 4) sur une paroi, tout en permettant un emboîtement autobloquant d'une autre lame 1' avec serrage élastique (force F) des lames 1' l'une contre l'autre (figures 18 et 19). Dans cette variante, l'emboîtement est réalisé uniquement par translation de la lame 1' dans le plan (X,Z) parallèle à la face arrière11 des lames et la une direction perpendiculaire à l'axe longitudinal (Z) de la rainure 120 (Figure 18/ Flèche G2).We have shown on Figures 16 and 17 , an example of a fitting accessory which comprises a connecting element 2 ', for fixing the edge 12 with groove 120 of a blade 1' referred to above ( figure 4 ) on one wall, while allowing a self-locking engagement of another blade 1 'with elastic clamping (force F) of the blades 1' against each other ( Figures 18 and 19 ). In this variant, the interlocking is achieved solely by translation of the blade 1 'in the plane (X, Z) parallel to the rear face 11 of the blades and the direction perpendicular to the longitudinal axis (Z) of the groove 120 ( Figure 18 / Arrow G2).

On a représenté sur les figures 20 et 21, un exemple d'accessoire de pose qui comprend un élément de liaison 2", permettant de fixer une lame 1" susvisée (figure 5) sur une paroi, tout en permettant un emboîtement autobloquant d'une autre lame 1" (Figure 22 et Figure 23).We have shown on Figures 20 and 21 , an example of a fitting accessory which comprises a connecting element 2 ", for fixing a blade 1" referred to above ( figure 5 ) on a wall, while allowing a self locking interlocking of another blade 1 "( Figure 22 and Figure 23 ).

On a représenté sur les figures 24 et 25, un exemple d'accessoire de pose qui comprend un élément de liaison 2"', permettant de fixer le bord 12 avec rainure 120 d'une lame 1'" susvisée (figure 6) sur une paroi, tout en permettant un emboîtement autobloquant d'une autre lame 1" (Figure 27 et Figure 28).We have shown on Figures 24 and 25 , an example of a fitting accessory which comprises a connecting element 2 "', for fixing the edge 12 with groove 120 of a blade 1""above ( figure 6 ) on a wall, while allowing a self locking interlocking of another blade 1 "( Figure 27 and Figure 28 ).

Dans les deux variantes des figures 5 et 6, il convient de noter qu'une fois les deux lames 1" ou 1'" accouplées l'une avec l'autre, en absence d'élément de liaison (Figure 5 ou Figure 6), la lèvre arrière 122 n'est pas déformée et n'exerce pas de pression de serrage sur la languette 130, contrairement aux variantes des figures 3 et 4. Dans ces deux variantes des figures 5 et 6, en absence d'élément de liaison, il existe une zone Z1 de quasi-contact entre la languette 130 et la face interne 122a de la lèvre arrière 122. Dans cette zone de quasi-contact Z1, la distance séparant la face interne 122b de la lèvre arrière 122 et la languette 13 est très faible, et n'est pas nécessairement nulle comme dans les variantes de figures 3 et 4, mais dans tous les cas est inferieure à l'épaisseur (e1) de la première partie 20 de l'élément de liaison 2" ou 2"'. Dans les deux variantes des figures 22, 23, 26 et 27, comme pour les variantes des figures 12 à 14, 18 et 19, lors de l'emboîtement de la languette 130 dans la rainure 120, la lèvre arrière 122 est déformée élastiquement avec une amplitude suffisante pour permettre un emboîtement autobloquant de languette 130 dans la rainure 120 malgré le surplus d'épaisseur ( e1) de l'élément de liaison 2" ou 2"'. Dans la zone correspondant à la zone de quasi contact Z1 susvisée (entre la languette 130 et la lèvre inferieure 122 en absence d'élément de liaison), on obtient un serrage de la première partie 20 de l'élément de liaison 2" ou 2'" entre la lèvre arrière 122 et la languette 130 introduite dans la rainure 120. On obtient également un écrasement du bourrelet 22 de l'élément de liaison 2" ou 2" dans la zone Z4 entre la languette 130 et la lèvre arrière 122.In both variants of Figures 5 and 6 , it should be noted that once the two blades 1 "or 1 '" coupled with each other, in the absence of connecting element ( Figure 5 or Figure 6 ), the rear lip 122 is not deformed and does not exert a clamping pressure on the tongue 130, contrary to the variants of the Figures 3 and 4 . In these two variants of Figures 5 and 6 in the absence of a connecting element, there is a quasi-contact zone Z 1 between the tongue 130 and the internal face 122a of the rear lip 122. In this quasi-contact zone Z 1 , the distance separating the internal face 122b of the rear lip 122 and the tongue 13 is very small, and is not necessarily zero as in the variants of Figures 3 and 4 but in all cases is less than the thickness (e 1 ) of the first part 20 of the connecting element 2 "or 2"'. In both variants of Figures 22, 23 , 26 and 27 , as for the variants of the Figures 12 to 14 , 18 and 19 during the engagement of the tongue 130 in the groove 120, the rear lip 122 is elastically deformed with a sufficient amplitude to allow interlocking interlocking tongue 130 in the groove 120 despite the excess thickness (e1) of the connecting element 2 "or 2"'. In the zone corresponding to the quasi-contact zone Z 1 referred to above (between the tongue 130 and the lower lip 122 in the absence of a connecting element), a tightening of the first part 20 of the connecting element 2 "is obtained. 2 '"between the rear lip 122 and the tongue 130 inserted into the groove 120. The bead 22 of the connecting element 2" or 2 "is also crushed in the zone Z4 between the tongue 130 and the rear lip 122 .

Dans tous les exemples précédemment décrits en référence aux figures, grâce à la déformation élastique de la lèvre arrière 122, deux lames peuvent encore être accouplées l'une avec l'autre par emboîtement autobloquant, avec un serrage de la première partie 20 de l'élément de liaison 2, 2', 2" ou 2'" entre la lèvre arrière 122 et la languette 130 introduite dans la rainure 120, au moins dans une zone correspondant à ladite zone Z1 de contact ou de quasi-contact entre la languette 130 et la lèvre arrière 122 en l'absence d'élément de liaison. Dans une autre variante, on pourrait obtenir le même résultat en mettant en oeuvre une lèvre arrière 122 en matériau élastiquement compressible. De même, il est possible de combiner la mise en oeuvre d'une lèvre arrière 122 élastiquement déformable et en matériau élastiquement compressible. Dans une autre variante, on pourrait également obtenir le même résultat, en mettant en oeuvre une lèvre avant 121 élastiquement déformable ou élastiquement compressible.In all the examples previously described with reference to the figures, thanks to the elastic deformation of the rear lip 122, two blades can still be coupled to one another by interlocking interlocking, with a clamping of the first part 20 of the connecting element 2, 2 ', 2 "or 2'" between the rear lip 122 and the tongue 130 inserted in the groove 120, at least in an area corresponding to said zone Z 1 of contact or quasi-contact between the tongue 130 and the rear lip 122 in the absence of connecting element. In another variant, one could obtain the same result by implementing a rear lip 122 of elastically compressible material. Similarly, it is possible to combine the implementation of a rear lip 122 elastically deformable and elastically compressible material. In another variant, one could also obtain the same result, by implementing a lip before 121 elastically deformable or elastically compressible.

Dans toutes les variantes des figures annexées, les deux lames peuvent encore être accouplées l'une avec l'autre par emboîtement autobloquant, avec un serrage de la première partie 20 de l'élément de liaison 2, 2', 2" ou 2'" entre la lèvre arrière 122 et la languette 130 introduite dans la rainure 120, grâce à l'élasticité d'une des deux lèvres de la rainure 120. Dans une autre variante, l'élément de liaison 2, 2', 2" ou 2'" peut être dans un matériau permettant un écrasement au moins de la première partie 20 de sorte que lors de l'emboîtement autobloquant des lames la première partie 20 de l'élément de liaison est écrasée entre la languette 130 et la lèvre arrière 122 au moins dans la zone de contact ou quasi-contact Z1, avec une diminution d'épaisseur suffisante de la première partie 20 de l'élément de liaison. Dans le cadre de l'invention, il est possible d'utiliser cette faculté d'écrasement de l'élément de liaison sans mise en oeuvre de lèvres arrière et avant élastiquement déformables ou élastiquement compressibles ou de combiner cette faculté d'écrasement de l'élément de liaison avec une lèvre arrière 122 élastiquement déformable ou élastiquement compressible et/ou une lèvre avant 121 élastiquement déformable ou élastiquement compressible.In all the variants of the appended figures, the two blades can still be coupled to each other by interlocking engagement, with a clamping of the first part 20 of the connecting element 2, 2 ', 2 "or 2' between the rear lip 122 and the tongue 130 introduced into the groove 120, thanks to the elasticity of one of the two lips of the groove 120. In another variant, the connecting element 2, 2 ', 2 "or 2 '"may be in a material allowing crushing of at least the first part 20 so that when self locking the blades the first part 20 of the connecting element is crushed between the tongue 130 and the rear lip 122 at least in the zone of contact or quasi-contact Z1, with a sufficient reduction in thickness of the first part 20 of the connecting element. In the context of the invention, it is possible to use this ability to crush the connecting element without implementation of elastically deformable or elastically compressible back and front lips or to combine this ability to crush the connecting element with a rear lip 122 elastically deformable or elastically compressible and / or a front lip 121 elastically deformable or elastically compressible.

Dans les exemples de réalisations susvisés, la première partie 20 de l'élément de liaison 2, 2', 2", 2'" est formée de manière à épouser la face interne 122a de la lèvre arrière 122. Dans une autre variante telle que celle illustrée sur les figures 28 à 30, la première partie 20 de l'élément de liaison 2"" peut être déformable de manière à épouser la face interne 122a de la lèvre arrière 122, une fois les deux lames emboîtées bord à bord. Cette déformation est obtenue lors de l'emboîtement des deux lames (Figure 30). Cette première partie 20 de l'élément de liaison 2"" peut par exemple être constituée par un film souple ou malléable, notamment un film plastique.In the examples of embodiments mentioned above, the first part 20 of the connecting element 2, 2 ', 2 ", 2''is formed so as to fit the inner face 122a of the rear lip 122. In another variant such that that illustrated on the Figures 28 to 30 , the first part 20 of the connecting element 2 "" can be deformable so as to match the internal face 122a of the rear lip 122, once the two blades are fitted edge to edge. This deformation is obtained during the nesting of the two blades ( Figure 30 ). This first part 20 of the connecting element 2 "" may for example be constituted by a flexible or malleable film, in particular a plastic film.

Dans tous les exemples précédemment décrits en référence aux figures, les éléments de liaison 2, 2', 2",2"', 2""sont utilisés pour fixer les lames sur une paroi. Dans une autre variante également couverte par l'invention, les éléments de liaison pourraient être adaptés pour être montés de manière mobile sur une paroi, par exemple en étant montés dans un rail de pose, de manière par exemple à réaliser un revêtement à pose flottante, avec une possibilité de dilatation des lames dans un plan parallèle à leur face arrière 11 dans la direction (axe Z) parallèle à leurs bords 12, 13 accouplés et/ou dans la direction (axe X) perpendiculaire à leur bords 12,13 accouplés.In all the examples previously described with reference to the figures, the connecting elements 2, 2 ', 2 ", 2"', 2 "" are used to fix the blades on a wall. In another variant also covered by the invention, the connecting elements could be adapted to be mounted movably on a wall, for example by being mounted in a laying rail, for example to achieve a floating laying coating, with a possibility of expansion of blades in a plane parallel to their rear face 11 in the direction (Z axis) parallel to their edges 12, 13 coupled and / or in the direction (X axis) perpendicular to their edges 12,13 coupled.

On a représenté sur les figures 31 à 33, une autre variante de réalisation dans laquelle les deux lames 1'" sont identiques aux lames de figures 26 et 27, et dans lequel l'élément de liaison 2""' comporte un film ou un languette souple ou malléable F, notamment un film ou une languette en plastique ou en métal, monté sur un support rigide 21. Le support 21 est solidarisé à une paroi, par exemple en étant positionné dans un rail de pose (non représenté) fixé à ladite paroi, et de telle sorte qu'une partie du film ou de la languette souple ou malléable F soit positionnée contre la face latérale 122b de la lèvre arrière 122 de lame 1'" (Figure 31). Le support 21 peut par exemple être monté coulissant dans ledit rail de pose. Ensuite, en référence aux figures 32 et 33, on emboîte la languette 130 de l'autre lame 1'" dans la rainure 120, en déformant le film souple ou malléable F, de manière à ce qu'au moins une partie 20 de ce film F épouse au moins la face interne 122a de la lèvre arrière 122, une fois les deux lames emboîtées bord à bord (Figure 33). Dans cette variante, mais non nécessairement, une fois les deux lames emboîtées bord à bord, une partie du film 20' du film ou de la languette F est positionnée entre les bords des deux faces avant visibles 10 des lames 1'" et est en saillie par rapport aux faces avant 10 visible des lames 1'". Cette partie 20' est ensuite découpée au moyen d'une lame coupante.We have shown on Figures 31 to 33 , another variant embodiment in which the two blades 1 '"are identical to the blades of Figures 26 and 27 and in which the connecting element 2 ""'comprises a flexible or malleable film or tongue F, in particular a film or a tongue made of plastic or metal, mounted on a rigid support 21. The support 21 is secured to a wall, for example by being positioned in a laying rail (not shown) attached to said wall, and such that a portion of the film or flexible or malleable tongue F is positioned against the lateral face 122b of the rear lip 122 of blade 1 '"( Figure 31 ). The support 21 may for example be slidably mounted in said laying rail. Then, with reference to figures 32 and 33 the tongue 130 of the other blade 1 '"is engaged in the groove 120, deforming the flexible or malleable film F, so that at least a portion 20 of this film F matches at least the inner face 122a of the rear lip 122, once the two blades are fitted edge to edge ( Figure 33 ). In this variant, but not necessarily, once the two blades interlocked edge to edge, a portion of the film 20 'of the film or the tongue F is positioned between the edges of the two visible front faces 10 of the blades 1'"and is in projecting from the visible front faces 10 of the blades 1 '". This portion 20 'is then cut by means of a cutting blade.

Dans tous les exemples précédemment décrits en référence aux figures, une fois les lames de revêtement accouplées bord à bord, l'espace résiduel entre les bords des faces avant 10 visibles des lames de revêtement est très faible ou est inexistant lorsque les bords des faces avant 10 des lames de revêtement se touchent. Dans une autre variante, l'espace résiduel entre les bords des faces avant 10 visibles des lames de revêtement emboîtées bord à bord pourrait être plus important.In all the examples previously described with reference to the figures, once the cladding blades are coupled edge-to-edge, the residual space between the edges of the visible front faces 10 of the cladding blades is very small or nonexistent when the edges of the front faces Liner blades touch each other. In another variant, the residual space between the edges of the visible front faces of the nested coating blades edge to edge could be more important.
