Description
PROCEDE DE FABRICATION DE LAMES DE REVETEMENT DE SOL ET LAMES ISSUES DE CE PROCEDE, INSTALLATION ET FEUILLE DECOR POUR LA MISE EN ŒUVRE DU PROCEDE.METHOD OF MANUFACTURING SOIL COATING BLADES AND BLADES THEREOF, INSTALLATION AND DECORATED SHEET FOR CARRYING OUT THE METHOD.
L'invention concerne un procédé de fabrication de lames assemblables pour la confection d'un revêtement de sol partant de panneaux décors découpés et usinés .The invention relates to a method for manufacturing assemblable blades for making a floor covering from cut and machined decorative panels.
L'invention concerne encore une installation et une feuille décor pour la mise en oeuvre de ce procédé et les lames pour revêtement qui en sont issues .The invention also relates to an installation and a decorative sheet for the implementation of this method and the coating blades that are derived therefrom.
La présente invention concerne le domaine de la fabrication de panneaux décor et de lames pour la confection de revêtements de sol.The present invention relates to the field of manufacturing decorative panels and blades for making floor coverings.
Dans ce domaine, on connaît plus particulièrement les revêtements de sols dits stratifiés, composés d'une pluralité de lames que l'on assemble par collage ou emboîtement mécanique.In this field, more specifically known so-called laminate flooring, composed of a plurality of blades that are assembled by gluing or mechanical interlocking.
Ces lames sont débitées à partir de panneaux stratifiés revêtus en face supérieure d'une couche décorative.These blades are cut from laminated panels coated on the upper face of a decorative layer.
A ce propos, de tels panneaux comportent une âme en bois ou à base de bois, par exemple de type HDF ou MDF, c'est-à-dire constituée à partir de fibres de bois aggloméré sous presse et par addition d'un liant tel qu'une résine. Cette âme du panneau peut encore être constituée en matériau synthétique, voire à partir de matières recyclées .In this regard, such panels comprise a core of wood or wood-based, for example HDF or MDF type, that is to say formed from pressed wood fibers in press and by addition of a binder such as a resin. This core of the panel can still be made of synthetic material, or even from recycled materials.
Par ailleurs, cette âme d'un panneau stratifié, reçoit, sur sa face supérieure, un revêtement décoratif composé d'une feuille imprimée d'un décor et imprégnée d'une résine polymérisable, par exemple de type mélamine ou autre. De manière similaire, sur ce revêtement décoratif est appliqué un overlay sous forme d'une feuille cellulosique imprégnée de résine et contenant une
charge, de type oxyde d'alumine, qui a la particularité de conférer au revêtement de sol une meilleure tenue à l'abrasion. Sur la face inférieure de tels panneaux stratifiés est appliquée une couche, dite balance, pour équilibrer les contraintes dans le panneau. Elle consiste, usuellement, en une simple feuille de papier kraft, également imprégnée de résine.Moreover, this core of a laminated panel, receives, on its upper face, a decorative coating consisting of a printed sheet of a decor and impregnated with a polymerizable resin, for example melamine or other type. Similarly, on this decorative coating is applied an overlay in the form of a cellulosic sheet impregnated with resin and containing a charge, of the alumina oxide type, which has the particularity of giving the floor covering better resistance to abrasion. On the underside of such laminated panels is applied a layer, called balance, to balance the stresses in the panel. It consists, usually, in a simple sheet of kraft paper, also impregnated with resin.
Ces différentes couches composant un panneau stratifié: overlay, revêtement décoratif, âme et balance, sont pressées à chaud pour les lier entre elles. Aussi, il convient de refroidir les panneaux avant de procéder à leur usinage pour en débiter les lames ou dalles destinées à confectionner le revêtement de sol .These different layers composing a laminated panel: overlay, decorative coating, core and balance, are hot pressed to bind them together. Also, it is necessary to cool the panels before machining them to cut the blades or slabs for making the floor covering.
Ainsi , en sortie de presse, ces panneaux mélaminés sont à une température de l'ordre de 1000C et en vue de leur refroidissement on procède à leur stockage jusqu'à stabilisation de leur température ce qui peut prendre un certain temps, en particulier lorsque ces panneaux sont stockés par empilement immédiatement à l'issue de l'opération de pressage.Thus, by press output, such decorative panels are at a temperature of about 100 0 C and with a view to their cooling is carried out to storage until stabilization of their temperature which may take some time, particularly when these panels are stored by stacking immediately after the pressing operation.
Or, justement, un tel refroidissement sur une période prolongée peut engendrer des contraintes au niveau de ces panneaux, comme cela est expliqué en particulier dans le document EP-O.978.359. Par ailleurs, plus le temps de stabilisation des panneaux est long, plus il est nécessaire de disposer des espaces de stockage importants d' où résulte une flexibilité et une réactivité de production moindre.However, precisely, such a cooling over a prolonged period can cause constraints on these panels, as is explained in particular in the document EP-O.978.359. Moreover, the longer the stabilization time of the panels, the more it is necessary to have large storage spaces resulting in flexibility and responsiveness of less production.
A noter, encore, que de tels espaces de stockage sont nécessairement des enceintes à ambiance contrôlée et nécessitant un équipement particulier qui augmente encore le coût de la surface dévolue aux panneaux en cours de refroidissement.It should be noted, again, that such storage spaces are necessarily space-controlled enclosures requiring special equipment which further increases the cost of the area devoted to the panels being cooled.
A cela il faut ajouter que l'opération de pressage à chaud pose, elle-même, un certain nombre de problèmes. En particulier, comme cela a été expliqué plus haut, l'âme du panneau peut être
constituée à partir de fibres ou particules, notamment de bois ou d'autres matériaux, agglomérés à l'aide d'un liant synthétique. Sous l'effet de la chaleur, de tels matériaux peuvent avoir des comportements divers. En particulier, il peut en résulter des déformations se traduisant par des effets de tuilage ou de banane des lames composant le revêtement de sol.To this must be added that the hot pressing operation itself poses a number of problems. In particular, as explained above, the core of the panel can be made from fibers or particles, in particular wood or other materials, agglomerated with a synthetic binder. Under the effect of heat, such materials can behave differently. In particular, it can result in deformations resulting in tiling or banana effects of the blades making up the flooring.
En outre, il en résulte nécessairement des phénomènes de dilatation différentiels entre les matériaux qui sont très difficiles à gérer et d'où découle, justement, la nécessité de soumettre les panneaux à une période de stabilisation prolongée à l'issue.In addition, it necessarily results in differential expansion phenomena between the materials that are very difficult to manage and from which stems precisely the need to subject the panels to a period of prolonged stabilization at the end.
De même, le papier subit une expansion lors de son imprégnation de mélamine et l'aspect décoratif du revêtement de sol que l'on souhaite obtenir peut en être perturbé .Similarly, the paper expands during its melamine impregnation and the decorative aspect of the flooring that one wishes to obtain can be disturbed.
De plus, on remarquera que les niveaux de brillance que l'on peut obtenir au niveau d'un revêtement de sol stratifié sont limités. Ce degré de brillance résulte, tout comme les effets de relief, des tôles qui habillent la table, ou, selon le cas, le coulisseau de la presse. Ainsi, à chaque fois que l'on souhaite changer ce degré de brillance des panneaux fabriqués il convient de remplacer la tôle destinée à venir en contact avec la face supérieure de ces panneaux, sachant, en outre, que de telles tôles sont soumises à usure et il convient de les remplacer ou de les retraiter en surface périodiquement.In addition, it will be appreciated that the levels of gloss that can be achieved at a laminate floor are limited. This degree of gloss results, as the relief effects, sheets that dress the table, or, as the case, the slide of the press. Thus, whenever it is desired to change the degree of gloss of the panels manufactured it is necessary to replace the sheet intended to come into contact with the upper face of these panels, knowing, moreover, that such sheets are subject to wear and they should be replaced or retreated periodically.
Comme cela a été indiqué plus haut, de cette tôle qui habille une presse découle, également, les effets de relief recherchés.As has been indicated above, this plate which dresses a press also results in the desired relief effects.
En particulier, certains revêtements de sol stratifiés comportent, en tant que revêtement décoratif, une imitation de carrelage, exigeant une différence de relief et d' aspect entre les carreaux et les joints délimitant ces derniers. Les difficultés à obtenir ces différents états de surface, combinés
au phénomène d'expansion du papier mélaminé décor, conduit à une fabrication de panneaux avec un taux de rébus important.In particular, some laminate flooring has, as a decorative coating, an imitation of tile, requiring a difference in relief and appearance between the tiles and the joints defining the latter. Difficulties in obtaining these different surface conditions, combined to the phenomenon of expansion of melamine-decor paper, leads to a production of panels with a high rate of rebus.
La présente invention se propose d' apporter une solution à l'ensemble des problèmes ci-dessus. Pour cela, il a été nécessaire, dans une première démarche inventive, d'aller à 1' encontre d'un préjugé de l'homme du métier selon lequel seule la solution de stratification permet d'obtenir un revêtement de sol d'une tenue mécanique suffisante pour une telle application.The present invention proposes to provide a solution to all of the above problems. For this, it was necessary, in a first inventive step, to go against a prejudice of the skilled person according to which only the laminating solution provides a floor covering of an outfit sufficient mechanical for such an application.
La solution selon l'invention résulte, par ailleurs, d'une remise en cause complète du procédé de fabrication de ce type de revêtement de sol stratifié. En particulier, c'est dans le cadre d'une seconde démarche inventive qu'il a été recherché une solution évitant tout apport de chaleur lors du surfaçage des panneaux. De manière particulière, selon le procédé conforme à l'invention, un panneau revêtu d'une couche décorative peut être immédiatement usiné pour la confection de lames de revêtement de sol.The solution according to the invention results, moreover, from a complete questioning of the manufacturing process of this type of laminate flooring. In particular, it was in the context of a second inventive step that a solution was sought that avoided any heat input when surfacing the panels. In particular, according to the method according to the invention, a panel coated with a decorative layer can be immediately machined for the manufacture of flooring boards.
Avantageusement, le procédé selon l'invention permet de concevoir une installation pour sa mise en œuvre comportant, immédiatement en aval une unité de production de panneaux, une unité de découpage et d'usinage pour débiter ces panneaux en lames ou dalles de revêtements de sols.Advantageously, the method according to the invention makes it possible to design an installation for its implementation comprising, immediately downstream, a panel production unit, a cutting and machining unit for cutting these panels into slabs or slabs of floor coverings. .
Selon un autre avantage du procédé selon l' invention, l'application d'une ou plusieurs couches de laque sur la face supérieure décorative des panneaux ou lames, permet de conférer au revêtement de sol un nombre infini d'aspect décoratif, brillant, mat, aspect ciré, nuance de teinte, mais, aussi, des propriétés particulières parfaitement adaptées à son usage .According to another advantage of the method according to the invention, the application of one or more layers of lacquer on the decorative upper side of the panels or blades, makes it possible to give the floor covering an infinite number of decorative, glossy, matte appearance , waxed appearance, nuance of hue, but, also, particular properties perfectly adapted to its use.
Ainsi, dans l'une au moins de ces couches de laque peut être incorporée une charge, tel que l'oxyde d'alumine pour en améliorer la tenue à l'abrasion. Cette propriété peut encore
découler du traitement spécifique d'une de ces couches de laque appliquée sur les panneaux et/ou lames, après découpage.Thus, in at least one of these lacquer layers may be incorporated a filler, such as alumina oxide to improve the abrasion resistance. This property can still result from the specific treatment of one of these layers of lacquer applied to the panels and / or blades, after cutting.
A ce propos, il convient tout particulièrement d'observer que s'il est connu, notamment dans le domaine des revêtements muraux, d'enrober des panneaux d'une feuille décor préimprégnée d'une couche de laque, le procédé et les vitesses de production des feuilles décor limitent les caractéristiques et propriétés que peut revêtir cette couche de laque d'imprégnation d.In this regard, it is particularly appropriate to observe that, if it is known, particularly in the field of wall coverings, to coat panels of a decorative sheet pre-impregnated with a layer of lacquer, the method and speeds of production of the decorative sheets limit the characteristics and properties that this layer of impregnation lacquer can take d.
Ainsi, les vitesses de production, de plusieurs centaines de mètres linéaires par minute de ces feuilles décor, ne permettent pas de mettre en œuvre des laques dont les propriétés , par exemple, de séchage ou de méthode d'imprégnation, ne peuvent tolérer de telles vitesses.Thus, the production speeds of several hundred linear meters per minute of these decorative sheets, do not allow to implement lakes whose properties, for example, drying or impregnation method, can not tolerate such speeds.
Justement, c'est dans le cadre d'une démarche inventive que l'on a su remettre en cause ces procédés de fabrication antérieurs et que l'on a constaté que les vitesses de production des panneaux pour revêtement de sol, y compris celle à laquelle sont débitées les lames depuis ces panneaux, n'ont rien à voir avec les vitesses d'impression d'une feuille décor. En effet, dans la fabrication de revêtement de sol on travaille à des vitesses de défilement largement moindres . De même , si le nombre d'impression de laque où l'épaisseur des couches appliquées sur une feuille décor est nécessairement limitée en cours de production de cette dernière, de telles restrictions n'existent pas dans une solution conforme à l' invention.In fact, it is in the context of an inventive step that these previous manufacturing processes have been questioned and that it has been found that the production speeds of the panels for floor covering, including which blades are cut from these panels, have nothing to do with the print speeds of a decorative sheet. Indeed, in the manufacture of flooring is working at scroll speeds much lower. Similarly, if the number of lacquer printing where the thickness of the layers applied to a decorative sheet is necessarily limited during production of the latter, such restrictions do not exist in a solution according to the invention.
Un autre avantage découlant de la présente invention consiste en ce qu' il est possible d' obtenir des lames de revêtement de sol parfaitement stables , ne présentant aucun risque de déformation qui résulterait de tensions internes suite aux opérations de surfaçage des panneaux dont sont issues ces lames.
Par ailleurs, le procédé selon l'invention évite tout stockage intermédiaire pour stabilisation des panneaux ou encore une quelconque unité de refroidissement.Another advantage of the present invention is that it is possible to obtain perfectly stable flooring blades, having no risk of deformation that would result from internal stresses following the surfacing operations of the panels from which these blades. Furthermore, the method according to the invention avoids any intermediate storage for stabilization of the panels or any cooling unit.
Un autre avantage découlant de la présente invention consiste en ce que l'âme d'un panneau peut être constituée en tout type de matériau, y compris dans des matériaux ne résistant pas à des températures aussi élevées que celles mises en œuvre dans un procédé de stratification usuelle.Another advantage deriving from the present invention is that the core of a panel can be made of any type of material, including materials that do not withstand temperatures as high as those used in a process. usual stratification.
De plus, dans la mesure où, pour l'application du revêtement décoratif, il est fait appel à des techniques d'enrobage classiques, telles que le calandrage, les panneaux supports ne sont pas nécessairement soumis à des pressions aussi importantes qui pouvaient limiter, jusqu'à présent, la nature des matériaux composant l'âme de ces panneaux.In addition, insofar as, for the application of the decorative coating, conventional coating techniques, such as calendering, are used, the support panels are not necessarily subjected to such high pressures which could limit, until now, the nature of the materials composing the soul of these panels.
Ainsi, l'invention concerne un procédé de fabrication de lames assemblables pour la confection d'un revêtement de sol partant de panneaux décors découpés et usinés, caractérisé par le fait qu'avant et/ou après découpage d'un panneau on applique sur la face supérieure décorative de ce dernier et/ou des lames découpées au moins une couche d'une laque.Thus, the invention relates to a method of manufacturing assemblable blades for making a floor covering from cut and machined decoration panels, characterized in that before and / or after cutting a panel is applied to the decorative upper face of the latter and / or cut blades at least one layer of a lacquer.
Selon l'invention, dans une première étape on applique par collage et calandrage une feuille décor au moins sur la face supérieure décorative d'un panneau, avant application de laque et découpage pour la définition des lames .According to the invention, in a first step is applied by gluing and calendering a decorative sheet at least on the decorative upper side of a panel, before applying lacquer and cutting for the definition of the blades.
Selon l'invention au moins une des couches de laque appliquée contient une charge d' oxyde d' alumine .According to the invention at least one of the applied lacquer layers contains a charge of alumina oxide.
L'invention concerne encore une installation permettant la mise en œuvre du procédé ci-dessus comportant :The invention also relates to an installation for implementing the above method comprising:
- une unité de découpage des panneaux en lames ;
- et des moyens d'imprégnation de la face supérieure décorative des panneaux et/ou des lames, après découpage, d'au moins une couche de laque.- a unit for cutting the panels into strips; - And means for impregnating the decorative upper face of the panels and / or blades, after cutting, at least one layer of lacquer.
Avantageusement, cette installation comporte encore une unité d'enrobage des panneaux d'une feuille décor.Advantageously, this installation also comprises a unit for coating the panels of a decorative sheet.
Finalement, l'invention concerne des lames de revêtement de sol résultant du procédé selon l'invention comportant une âme à base de bois ou en matériau synthétique et/ou en matériau recyclé, caractérisée par le fait que sur leur face supérieure décorative est appliquée au moins une couche de laque.Finally, the invention relates to flooring panels resulting from the process according to the invention comprising a core based on wood or in synthetic material and / or recycled material, characterized in that on their decorative upper surface is applied to the less a layer of lacquer.
Avantageusement, la ou les couches de laques sont appliquées sur une feuille décor préalablement collée sur la face supérieure décorative des lames.Advantageously, the layer or layers of lacquer are applied to a decorative sheet previously bonded to the decorative upper face of the blades.
La présente invention et ses avantages seront mieux compris à la lecture de la description qui va suivre se rapportant à un exemple de réalisation et en référence au dessin ci-joint.The present invention and its advantages will be better understood on reading the following description relating to an exemplary embodiment and with reference to the attached drawing.
- la figure 1 est une représentation schématisée et en coupe d'une lame de revêtement de sol résultant d'un procédé de fabrication conforme à l'inventionFIG. 1 is a diagrammatic representation in section of a floor covering blade resulting from a manufacturing method according to the invention;
- la figure 2 illustre, de manière schématisée, une installation pour la mise en œuvre du procédé de fabrication de revêtement de sol selon l' inventionFIG. 2 schematically illustrates an installation for implementing the flooring manufacturing method according to the invention;
Tel que visible dans la figure 1 , la présente invention a trait au domaine des revêtements de sols . Un tel revêtement de sol est composé de lames 1 ou dalles issues de panneaux 2 visibles dans le schéma de la figure 2, souvent revêtues par surfaçage d'une feuille décor 3.
Plus particulièrement, un panneau 2 à partir duquel sont débitées les lames 1 comporte une âme 4 qui peut être constituée en des matériaux divers . En particulier, cette âme 4 peut être à base de bois, notamment en HDF, MDF ou en bois aggloméré, comme elle peut être constituée en un matériau synthétique, voire à base de matériaux recyclés.As seen in Figure 1, the present invention relates to the field of floor coverings. Such flooring is composed of blades 1 or slabs from panels 2 visible in the diagram of Figure 2, often coated by surfacing a decorative sheet 3. More particularly, a panel 2 from which the blades 1 are cut has a core 4 which may be made of various materials. In particular, this core 4 can be based on wood, especially HDF, MDF or wood chipboard, as it can be made of a synthetic material, or even based on recycled materials.
Quant à la feuille décor 3 que peut recevoir un tel panneau 2 sur sa face supérieure 5 , elle résulte d' un procédé d' impression habituel. A noter que sur sa face inférieure 6 d'un tel panneau 2 peut être appliquée une couche d' un revêtement d' équilibrage 13, souvent dénommée balance, voire une couche d'un matériau d' isolation acoustique .As for the decorative sheet 3 that can receive such a panel 2 on its upper face 5, it results from a usual printing process. Note that on its underside 6 of such a panel 2 may be applied a layer of a balancing coating 13, often called balance or even a layer of sound insulation material.
Selon le procédé conforme à l'invention, on applique sur la face supérieure décorative 5 ; 5A des panneaux 2 ou des lames 1 débitées partant de ces panneaux 2 , au moins une couche de laque 11.According to the process according to the invention, it is applied to the decorative upper face 5; 5A panels 2 or blades 1 debited starting from these panels 2, at least one layer of lacquer 11.
En cas d'enrobage des panneaux 2 d'une feuille décor 3, cette application d' au moins une couche de laque intervient postérieurement à cet enrobage.In case of coating the panels 2 of a decorative sheet 3, this application of at least one lacquer layer occurs after this coating.
Avantageusement, la feuille décor 3 est appliquée sur le panneau 2 par collage et calandrage. A ce propos, il est particulièrement utilisé une colle de type urée-formol 8.Advantageously, the decorative sheet 3 is applied to the panel 2 by gluing and calendering. In this connection, it is particularly used a urea-formaldehyde type adhesive 8.
De la même manière et en employant le même type de colle la couche d'équilibrage 13 peut venir revêtir la face inférieure du panneau 2.In the same way and by employing the same type of glue, the balancing layer 13 can coat the underside of the panel 2.
Ainsi, dans une unité de surfaçage S, on vient encoller, par des moyens adaptés , tout ou partie de la face supérieure 5 du panneau 2 avant d'y appliquer, notamment par calandrage, la feuille décor 3.
Ces panneaux 2 , en sortie de cette unité de surfaçage S , sont acheminés par des moyens de transfert 9 prévus en conséquence, en direction d'une unité d'usinage 10 où ils sont découpés en lames 1, lesquelles sont encore profilées, en périphérie, pour définir les moyens d'emboîtement, de type rainure et languette, permettant l'assemblage de ces lames par collage ou liaison mécanique .Thus, in a surfacing unit S, all or part of the upper face 5 of the panel 2 is glued, by suitable means, before applying, in particular by calendering, the decorative sheet 3. These panels 2, at the output of this surfacing unit S, are conveyed by means of transfer 9 provided accordingly, in the direction of a machining unit 10 where they are cut into blades 1, which are further profiled at the periphery. to define the interlocking means, tongue and groove type, allowing the assembly of these blades by gluing or mechanical connection.
Ainsi, cette unité d'usinage 10 peut se décomposer en une machine de découpe et une machine de profilage, tout comme ces opérations sont susceptibles d'être réalisées simultanément dans une même unité.Thus, this machining unit 10 can be broken down into a cutting machine and a profiling machine, just as these operations can be performed simultaneously in the same unit.
De manière plus particulièrement avantageuse, au moins une des couches de laque 11 constitue une protection à l'abrasion du revêtement de sol. Cette couche comporte, avantageusement, une charge d' oxyde d' alumine pour garantir cette résistance à l'abrasion.More particularly advantageously, at least one of the lacquer layers 11 is a protection against abrasion of the floor covering. This layer advantageously comprises a charge of alumina oxide to guarantee this abrasion resistance.
L'installation permettant la mise en œuvre du procédé comporte, par conséquent, entre l'unité de surfaçage S et l'unité d'usinage 10, voire entre une machine de découpage et une autre de profilage, des moyens d'application 12 d'une telle laque.The installation allowing the implementation of the method therefore comprises, between the surfacing unit S and the machining unit 10, or even between a cutting machine and another profiling machine, application means 12. such a lacquer.
A noter qu'à de tels moyens d'application 12 peuvent être associés des moyens de séchage adaptés au type de laque mis en oeuvre . En particulier, de tels moyens de séchage peuvent emprunter la forme de rayonnement UV, un canal de séchage à air chaud puisé...It should be noted that such means of application 12 may be associated with drying means adapted to the type of lacquer used. In particular, such drying means can take the form of UV radiation, a pulsed hot air drying channel ...
On observera qu'au travers du procédé selon l'invention, le nombre de couches de laque dont peut être revêtue une lame est illimité, contrairement à une feuille décor pré-imprégnée de vernis. De même, il est ainsi possible d'obtenir une grande diversité dans les finitions et les teintes de la surface décorative 5A de ces lames. En effet, une couche de laque, en
dehors de présenter certaines caractéristiques destinées à améliorer les propriétés physiques du revêtement de sol, peut contribuer à l'aspect esthétique de ce dernier.It will be observed that through the method according to the invention, the number of layers of lacquer which can be coated a blade is unlimited, unlike a decorative sheet pre-impregnated with varnish. Similarly, it is thus possible to obtain a great diversity in the finishes and colors of the decorative surface 5A of these blades. Indeed, a layer of lacquer, in Apart from presenting certain characteristics intended to improve the physical properties of the flooring, can contribute to the aesthetic appearance of the latter.
Cette solution selon l'invention offre également la possibilité au fabricant de proposer à sa clientèle une grande variété de revêtements de sols différents .This solution according to the invention also offers the possibility to the manufacturer to offer its customers a wide variety of different floor coverings.
De manière plus particulière à l'invention, en travaillant à des vitesses d'application largement inférieures à celles dans le domaine de l'imprégnation de feuille de papier décor, pour certaines caractéristiques physiques, en particulier la résistance à l'usure et à l'abrasion du revêtement de sol, il est possible d' atteindre des valeurs largement supérieures à celles connues jusqu'alors.More particularly to the invention, working at application speeds much lower than those in the field of the impregnation of decorative paper sheet, for certain physical characteristics, in particular the resistance to wear and tear. Abrasion of the floor covering, it is possible to achieve values much higher than those known hitherto.
D'ailleurs l'invention porte encore sur une feuille décor 3 pour la mise en œuvre du procédé décrit ci-dessus, feuille décor dont la face décorative comporte un traitement de surface destiné à favoriser l'accrochage d'une couche de laque.Moreover, the invention also relates to a decorative sheet 3 for the implementation of the method described above, decorative sheet whose decorative face comprises a surface treatment to promote the attachment of a lacquer layer.
Cette solution, combinée à celle consistant à appliquer la feuille décor par collage sur les panneaux, conduit à une installation pour la fabrication de revêtement de sol particulièrement optimisée, évitant tout stock intermédiaire de stabilisation ou de refroidissement, comme usuellement nécessaire en matière de revêtement de sol stratifié.This solution, combined with that of applying the decorative sheet by gluing on the panels, leads to a facility for the production of particularly optimized flooring, avoiding any intermediate storage of stabilization or cooling, as is usually necessary in laminate floor.
Ainsi , l' invention vient répondre, de manière tout particulièrement avantageuse aux solutions de l'état de la technique .
Thus, the invention responds in a particularly advantageous manner to the solutions of the state of the art.
